In his book, Popular Garden Flowers, published by Grant Richards Ltd. In 1911, Walter Wright, perhaps the greatest authority on gardenat the beginning of the twentieth century, writes:
‘However great our enthusiasm for the gladiolus . . . we have to acknowledge that it can hardly be classed as one of the greatof the people.’
Obviously the impact of the discovery of the primulinus race of the gladioli, discovered close to the Victoria Falls in 1902, and which brought about a revolution in hybridizing the gladiolus, had not by 1911 made its presence felt. The discovery of the Primulinus gladiolus may be said to have revolutionized the flower until it may safely be said that the gladiolus has made greater headway with flower lovers than perhaps any other flower. Certainly the Dutch bulb growers now state that they raise and sell more gladioli corms than corms or bulbs of any other flower and this includes the vast narcissus group. The gladiolus, too, has become internationally popular, as witness the large number of entries at the Annual Show of the British Gladiolus Society, which come from all parts of the world, with hybridists in Canada and New Zealand perhaps leading the field with new varieties of exhibition standard. To-day the gladiolus is a florists’ flower in the true sense – the colour range cannot be compared with that of any other flower, while the great improvement in size and quality of the individual florets must be beyond the imagination of the early twentieth-century gardeners.

The modern gladiolus may be divided into four distinct.
(a) The Colvillei Section, used for early flowering under glass.
(b) The large-flowered section, the result of combining various distinct strains.
(c) The primulinus group which for the first time opened up the way for introducing the yellow colouring into the large-flowered section – and
(d) The new miniature and butterfly gladioli which of recent years have given the gladiolus an even greater popularity than it was enjoying prior to their introduction. This is an era of the small garden and these are plants which possess the magnificent colouring of their larger-flowering brothers, added to which is a daintiness of flower and habit which makes them the ideal small-garden flower.
Each section is most suitable forand the appreciation of flowers in the home, which compensates for our restricted gardens and has contributed greatly towards the present popularity of the flower.
For cultural purposes we may make only two divisions, Section A, the indoor-flowering gladioli – and Sections B, C, and D, which are outdoor-flowering and which are all given much the same culture. It must, however, be said that the Colvillei group will bloom well in a sheltered border in favourable districts of the south if the corms are planted in autumn
THE COLVILLEI GLADIOLI
Growing to a height of only 18 in. and flowering during March, these dainty plants require almost the same treatment as, and like they must be grown in light. They will never grow to perfection as will and tulips in partial shade. Again, like freesias they must be given no water until growth appears. The corms are most inexpensive and are best planted late in August, my method being to set the corms in 48-size 2-in. Deep, placing three to each pot. Use an acid-free soil for gladioli do not like acid conditions. If in doubt, add a handful of lime rubble to each pot and the same amount of peat or decayed mushroom-bed manure, and some sand.
The pots are then removed to a plunge bed, under a wall is ideal, where the pots are covered with 4 in. of sand or weathered ashes and there they remain, covered with corrugated sheets or frame lights until early January. Very gentle forcing only is required, a temperature of 50 F. being suitable and very careful attention must be given to, giving only the minimum to keep the soil in a just moist condition. If there is any doubt about the having sufficient light in midwinter it is better to leave the pots in the outdoor beds until mid-February when light conditions are better. In any case, to provide a succession of bloom it is better to bring the pots indoors at fortnightly intervals. The blooms may need some support which should be provided by means of thin canes tied with raffia.
VARIETIES AND SPECIES FOR INDOOR FLOWERING
- Colvillei, The Bride. This is perhaps the purest white flower in cultivation, for not only are the petals pure white, so are the anthers.
- Colvillei rubra. Richest carmine-red, a grand companion to The Bride.
- Nanus, Amanda Mahy. This is a bright salmon-red-flowering species, which produces a spike of but 12 in. long. It is valuable in that it may be planted early October both in a sheltered in the open and in small pots for indoor flowering in May. The corms may be grown on entirely in a cold frame. Outdoors it blooms from mid-June and is so useful for bridging the gap between the early Colvillei flowering and the earliest of the summer-flowering gladioli which come into bloom in July.
- Nanus, Spitfire. Bears a bloom of rich scarlet with crimson markings.
LARGE OR SUMMER-FLOWERING GLADIOLI
The gladiolus is one of the easiest of all plants to grow well and provided the soil has been well dug and thoroughly cleaned, the corms will bloom to perfection. They do enjoy a soil which has been previously manured for a crop of peas or potatoes, for they should not be given any manure which is too rich in nitrogen. This will cause the spike to become too tall and soft and the flowers will lack the much-desired brightness of colour.
The exhibitor will go to any lengths in the preparations of his soil, but for the amateur and for the grower who wishes to grow gladioli on a commercial scale, a well-prepared soil that is in no way sour is all that is necessary. By a well-prepared soil is meant one manured for a previous year’s crop and with which is incorporated some additional humus-forming materials, for this is what the gladiolus revels in. Spent hops, peat, old mushroom-bed manure, decayed, all are suitable and should be forked in during March, the ground having been dug and allowed to weather over winter. The often sour soil of a town garden should have a light dressing with lime. At planting-time, a 2-oz. per square yard dressing with bone meal and liberal quantities of bonfire-ash raked in will supply the slow-acting fertilizers and the much-needed potash to build up sturdy growth and enhance the colour of the blooms.
The gladiolus is not particular as to whether the soil is light and sandy or of a clay nature. I have grown exhibition quality spikes in all soils, but what the plant does require is a soil that is well drained. A cold, wet soil will never grow good gladioli, the corms may even rot away beforeaction commences and those that do grow will be extremely late in flowering. Should the soil be heavy, it will be better to plant the corms in wide trenches, at the bottom of which should be placed a 3-in, layer of ashes or sand. The soil preparation should be done in autumn or early winter to allow for a firm bed at planting-time. If the ground is of an impoverished nature and some rotted manure is available this should be incorporated with the lower soil for the corms should never be allowed to come into direct contact with manure though humus is another matter.
Equally important as the preparation of the soil, is situation, for it must be remembered that gladioli grow to a height of anything up to 4 ft., and even the more dwarf primulinus and miniatures may be seriously damaged by winds especially when theare heavy with fully opened blooms. Delightful as they are in a mixed border, I feel that gladioli are at their best when planted in beds to themselves, for here they may be given the culture they deserve, and the brilliance of their blooms may be seen without any distractions. But in this way they must be given protection against strong winds and they are essentially lovers of the sun. Give them a southerly aspect and ample protection against the prevailing winds. A substantial hedge or wattle hurdles are ideal and with this protection it is possible to grow gladioli by the acre without the additional labour of individual staking.
PLANTING THE CORMS
For early blooms, those situated in the favourable districts of the south-west may plant any time from March 1st. In the south Midlands planting may be done at the end of March and in the colder north, early April is soon enough. It is important to allow the ground time in which to become warm and should the warm spring weather be long delayed it will be far better to wait a week or so longer than the usual planting-time. Corms, bulbs orwhich are in soil too cold to allow any root growth will be better left in their containers. Again, it is a debated point as to whether the gladiolus is perfectly hardy and growth should not be too advanced whilst hard frost is likely to be experienced.
Planting should be done to provide a succession of bloom, though it must be remembered that the varieties themselves will naturally bloom at various times and in a cold exposed position it will be advisable to plant early and quick-maturing varieties. This is far more important than generally realized. For instance, the new small-flowered variety, Scotia, a lovely yellow with peach markings, will take up to a hundred days to reach maturity, compared with only eighty days taken by the lovely ruffled miniature variety Statuette. Should it not be suitable for planting the corms before mid-April, it will mean that Scotia may not be in bloom until August and in the cold, wet summer of 2002 it was September before it flowered in my exposed garden, when the blooms were little appreciated in the cold, wet autumn. Where planting can be done early in March the variety matters little, but those with exposed gardens would be advised to concentrate on early and mid-season varieties.
The size of the corm is a matter for consideration. The medium-sized high-crowned corm is the best and will produce a larger spike and of better quality than a flat, but possibly larger corm. Not all varieties produce the same sized corm and a 10-12 cm. corm of some varieties may give as good a flower spike as x 1-14 cm. corms of some other varieties. Like the very large-sizedcorms which have become acclimatized to the soil and climate in which they were grown for so long, I believe that the 14-16 cm. corms have passed their most vigorous best, and for an exhibition spike, the 12-14 cm. size is most suitable. The cut-flower grower, growing for a market that is not quite up to the best standards, will find the 8-1 o cm. size quite suitable, though for a top-quality market spike the 10-12 cm. size is the best. The corms will cost about one-third more than for the smaller size, but prices obtained for the bloom will more than compensate. Again, if growing on for a second season, the 10-12 cm. size is a necessity for after the spikes, even if several leaves are allowed to remain, the corm will produce a smaller spike in its second season. If in the first place the 8-10 cm. Corm is used the spike produced the following season will be of no use for marketing. However, it must be remembered that certain varieties will produce a larger spike from the same sized corm as others.
The corm should be firm at the top when gently pressed with the fingers and it should not show any blemishes, neither should it be blackish brown in appearance or it may signify `fusarium yellow’ disease.
By far the best way of planting seems to be in trenches, for here the ground may be given more concentrated attention and staking and cutting may be more easily carried out. As the gladiolus is essentially a cut flower, the beds should be of sufficient width to make cutting as easy as possible and trenches 2 ft. wide are sug gested. Again and even more important, if the same distance is allowed between the beds or trenches, this ground can be used in alternate years so that the corms are not grown on the same soil for two successive years.
Plant the corms with a trowel or spade but never with a dibber, for no cavity must be allowed beneath the base where theare produced. When planting in trenches a popular method is to remove a 4-inch depth of soil with a spade and to ‘set’ the corms rather than to ‘plant’ them. I think 4 in. is the correct planting depth on a heavy loam, but so as to give greater support to the spike, those corms being planted into a light sandy soil are best planted 5-6 in. deep. Also in soil which tends to be of a wet nature, slightly shallower planting will be advised.
Should the weather be unduly dry at planting-time, it is vital to water the ground, for the base of the corms will tend to rot away if root action is delayed.
On ground that is well drained the trench bed system is to be recommended in preference to the more popular idea of planting in raised beds for not only ismore effective in dry weather, but it is possible to earth-up the plants as top growth takes place – or a soil and peat mulch may be given around the plants. This will not only assist the plants during dry weather but more important, it may do away with any need to stake the plants, especially in the case of the smaller-flowering varieties. The corms may be planted anything up to 12 in. apart. The commercial growers will plant in beds with a pathway between each and the corms will be set no more than 6 in. apart. In this way they will support each other and if earthed-up, little or no staking will be necessary.
When planting in mixed borders, it is preferable to plant about 9 in. apart in groups of four. The flower spikes may then be supported by tying green twine around the clump and if in a sheltered position it may then be possible to do away with a stake. If growing in a position which will be swept by winds, beds of gladioli should be supported by extending twine along the rows fastened to stout stakes at each end and at every six feet. The exhibitor will stake every individual spike, which will take away the charm of the flower whilst in the garden, but the exhibitor is only concerned about how the spike will look on the show bench and gives no thought to the plant for providing colour in the garden, or when used for indoor floral.
Planting the corms directly on to a layer of sand is often recommended, but I have never found this method necessary except on a very heavy, wet soil which may not grow good gladioli even with the sand.
Corms planted early in April will appear above the soil at the end of the month, but they will require no attention until about June 1st when the first earthing-up may be necessary and spraying once each week with a weak solution of potassium permanganate which will make the leaves bitter and so keep off fly attacks. Then as soon as the first sign of buds appears, which is apparent when theappears swollen, generally about mid to late June, gentle should be commenced.
This is the most vital stage in the life of the gladiolus, for on it depends not only length of stem and quality of the bloom, but also the vigour of the corm for next season and the formation of the cormlets for growing on. As it is necessary to provide the cormlets with both nitrogen and phosphates, this is best provided as diluted animal-manure water, made by dissolving poultry, pig, sheep or horse droppings by suspending the droppings in a bag into a barrel or tank of water.
Bearing in mind that it is far better to provide the corms with a continuous supply of dilute fertilizer rather than an occasional concentrated, the manure water should be used once a week. An excellent method of applying this is to make with the back of a rake, a drill 2-in. Deep on either side of the bed or trench and to pour the manure water into the drills It will gradually find its way to the corms.
Gladioli also love soot water which may be given once a month or even alternate fortnights in addition to the liquid manure. It cannot be stated too often that feeding should continue until long after the flower spike has been removed, right into early autumn so that the old corm will be built up for the following season’s flowering and the cormlets will continue to make growth.
The corms will appreciate a mulch of peat or hop manure during late June for though the gladiolus enjoys a position of full sun, it will not tolerate a soil which is too dry. In fact, during a dry period and especially if the soil does not contain much humus, regular soaking in addition to the manure water application is essential to the formation of a first-class spike and good spawn growth.
GROWING GLADIOLI UNDER CLOCHES
The gladiolus is one of the most profitable of all flowers under barn-type cloches or Ganwicks. It is a flower that t oes well under glass, but it makes such rapid growth that though an early flower spike will make a good price a spike which makes too much early growth and which necessitates the removal of the glass cover before the often cold, frosty and windy May weather has departed, may be spoilt because of its earliness. So cloching and planting is not advised before mid-March, so that the coverings may be removed towards the end of May.
The trench method is most suitable, made to the width of the glass to be used and dug about jo in. deep. It should be prepared as described but 3 in. from the top of the trench should be left which will allow the flower stems to make the maximum growth whilst still covered with the cloches. The corms should therefore be planted 6 in. below the top of the trench, being 3 in. deep in the soil. Plant in rows allowing 6 in. between each corm. Closer planting is not advised formight prove troublesome. It is advisable to prepare the trench during early winter to allow time for consolidation and the cloches should be placed over the trenches at the end of February to allow the soil to warm up before planting the corms. Feeding with liquid manure and soot water should continue from mid-May and as soon as the cloches are removed the top 3 in. of soil should be filled in to give the plants extra support, peat or hop manure being mixed with soil for this purpose which also acts as a mulch.
CUTTING AND MARKETING THE BLOOM
The flower spike will be ready for cutting for market and indoor decoration as soon as the first or lower floret has fully opened and the others will be showing colour. The top blooms will then open gradually in water and give pleasure over a long period. The spikes will also pack and transport with the minimum of bruising. When cutting, leave as many leaves as possible, two being a minimum, four if possible, so that the corms may be nourished for future use. The flower stems should not be broken, but cleanly severed with a sharp knife or scissors. Market bunches are generally of six spikes, which should be tied with raffia just under the open lower bloom and again at the bottom of the stem to make them secure. It is advisable to stand the stems in cold water for several hours before boxing or marketing.
Gladioli used in the home will remain in a fresh condition for a greater period if half an inch of stem is cut off every three days and fresh water provided.
PROPAGATION OF THE CORMLETS
Though the gladiolus is not difficult to grow from, named varieties may only be increased by growing on the tiny corms or spawn to be found clustered at the base of the old corms when lifted in October. Some varieties are fairly shy with their cormlet production, others produce spawn in abundance, the shy varieties remaining more expensive even though they may be long-established varieties. During the course of a growing season the gladiolus produces a completely new corm, perhaps two, immediately above the corm originally planted which will have withered away entirely. Upon lifting, the decayed corm should be removed and burnt. The cormlets, varying in size from little more than pinheads to small corms will be found clustered round the base of the newly formed corm. Every one, however small, will be carefully removed, for all will eventually grow into flowering-sized corms. The very smallest will take up to three years to attain flowering size, those which are larger will bloom in two years. This being the case it is advisable to segregate them in two sections, using clean paper bags in which are punched several air holes to store them during winter, having removed all soil particles at lifting-time.
The cormlets are grown on in beds, the soil first being brought to a fine tilth with the back of the head of a rake – drills 1 in. deep are made 6 in. apart and along each is sprinkled a mixture of peat and some coarse sand. The cormlets are then dropped into the drills in the same way as for planting peas, early April being the most suitable time. A position of full sun is advisable and it is essential to keep the ground free from weeds. Neither must the corms be allowed to suffer from lack of moisture. An aid to germination is to place the cormlets in a warm room for a fortnight before planting out and to immerse them in cold water the night previous to planting. So that they may be handled easily, they should be taken from the water an hour before required for planting and partially dried off in a warm room. They must not be allowed to flower during their stay in thebed, as all their energies must be reserved for the formation of a substantial corm. The corms should be fed with dilute liquid animal-manure water during August and September and they are lifted and stored in early October in the same way as for mature corms.
LIFTING AND STORING
During May 2001, much interesting correspondence appeared in Amateur Gardening about the hardiness of the gladiolus corm, several correspondents writing to say that during the severe winters of 1998 and 1999, corms that were lifted and stored in a supposedly frost-proof room suffered tremendous losses, while a number inadvertently left in the ground came though the winter unharmed.
In the south-west country, I have frequently allowed corms under barn cloches to remain in the ground throughout the winter, giving them no other attention than the removal of the yellow leaves late in October, followed by a heavy peat mulch. The corms are covered with the cloches early in December, and where time is limited, this method may be recommended. Those living in the north and Midlands would be advised to lift the corms by mid-October, as soon as the foliage appears to be turning yellow. My own method is to remove the cormlets and as much soil as possible, then to string up the corms in separate varieties in a dry, airy room for three weeks before cutting away the foliage and placing the corms, cleaned of all soil, into wooden trays, stacked above each other in a frost-proof room. It is not advisable to keep the corms near to hot-water pipes or a stove, for they may shrivel. This particularly applies to the cormlets which, if allowed to become dry and hard like peas, may take many weeks to sprout when planted out in April, which will mean that they may take considerably longer to attain flowering-size corms.
If a frost-proof room cannot be provided, then it may be safer to leave the corms in the ground and to cover them with a heavy mulch of peat or decayed leaves and some straw.
Care should be taken in lifting so as not to bruise the corms or lose the cormlets. With many of the new introductions likely to remain expensive for many years, it is suggested that far more attention should be given to rearing the cormlets, as the work is interesting and will mean a great saving financially.
DISEASES AND PESTS
Fusarium Rot. Gladioli are relatively free from diseases, but the rotting of the corms during storage caused by this disease must account for considerable losses each year. The fungus, fusarium oxysporium, attacks the corm from the roots, causing the leaves to turn prematurely yellow and the flower spike to be stunted. If the corm is cut open it will be found to be in a rotten condition, but in many cases no sign of this condition can be detected on the outside of the corm, until it has been kept over winter. A dry atmosphere for storage will do much to keep the trouble under control. Some varieties such as Picardy and Puccini are highly resistant and for this reason should be used more frequently in the introduction of new varieties. Some control will also be achieved in rotational cropping and in the regular sorting of all corms once each month throughout the winter, but since it attacks the corms from the inside control by the use of any chemicals is impossible when once the fungus is present.
Septaria. This is the ‘hard rot’ disease of gladioli which may attack a whole batch of corms in storage. The disease does not attack the core of the corm as does Fusarium Rot, only does it affect the outside of the corm in the form of reddish patches and though it does not appear to be the direct cause of the corm’s collapse, its presence will open up the corm for the entry of the dreaded Fusarium disease. Septaria is generally present on the fresh foliage of plants growing in the warm, moist climate of the south-west. Apart from rotation of cropping, the foliage should be regularly sprayed with Bordeaux Mixture, when the brown blotches are observed on the leaves. Dipping the corms for an hour just before planting in a o.I per cent solution of mercuric chloride, a deadly poison which should not be used when there are children about, will control the disease.
Thrips. This is a pest which attacks all parts of the gladiolus, particularly the leaves, causing them to turn brown. But the most serious aspect is in the ability of the pests to work their way into the corms and toon them during winter storage. Where they have made their presence felt, corm infestation may be reduced by removing the foliage completely before the corms are lifted. A more thorough control may be achieved by dusting the corms with napthalene as soon as they are set out in the trays, covering them with old sacking or newspaper to retain the fumes. The napthalene should be used at the rate of 1 oz. for every loo corms and is perfectly safe to use – or a dusting at monthly intervals with 5 per cent D.D.T. Will also ensure partial control.

This delightful section of recent introduction has created a new interest in the gladiolus. The miniatures are ideal plants for the small garden and most attractive when used for floral display indoors. Mixed with the large-flowering section they are most delightful, or used for filling in spaces towards the front of a border where they should be planted in clumps of five or six. The florets are elegantly ruffled, providing a charmingly coy effect.
Just beginning to make their mark, this delightful section with their attractive hooded upper petal are superb for cutting, like the miniatures, remaining in a fresh condition at least ten days when cut. These plants may be characterized by the ‘open’ formation of the florets up the stem. If possible, their colour range is far wider than that of the large-flowering section, several of them, like the scarlet-edged white Atom, being edged with gold and white.
