How To Grow Violets

Types. There are two main groups, the Parma violets, with double flowers, and the singles. These latter may be further split up into ‘hardy’ for flowering outdoors in winter, and ‘large flowered’ for flowering in frames. A few singles have petaloid centres to the blooms and are termed ‘semi-double.’

Soil and Situation. A cool, rich, rather heavy soil suits all violets best and they like a sheltered position shaded from the noonday sun. Manure or compost can be used freely in the preparation of the summer quarters,.

Propagation. New stock should be raised every year, either from cuttings, taken in Aug—Sept., or by offsets (young rooted pieces) pulled from old clumps in March—April. Cuttings are prepared from the ends of runners, but in other ways are made, inserted, and treated in exactly the same manner as those of violas or pansies.

Cultural Routine. Rooted cuttings or offsets are planted out in March—April, singles 1 ft. apart in rows 18 in. apart, doubles 6 in. apart in rows 1 ft. apart. Water in freely if weather is dry. Subsequently keep hoed, feed with dilute liquid manure frequently during the summer and spray with derris or malathion occasionally to keep down red spider.

Frame Culture. Make up beds of loamy soil, with plenty of leaf-mould or peat and a little sharp sand, to within 6-9 in. of the glass. Transfer clumps to these in September with large balls of roots and soil and plant so that leaves are just touching. Ventilate freely at first, more sparingly as weather becomes cold. Water moderately. Stir soil occasionally with a pointed stick.
