Summer is the most active time for many house andplants. Sunlight is at its strongest, the temperature is at its highest, and plants respond by growing and flowering. For this they need energy from food and water, and it’s up to you to keep them satisfied.
Many summer tasks are general ones: removing faded, to encourage bushy growth and keeping plants tidy. Other tasks, such as providing high , are mainly seasonal.
Feed and water generously
Feed most house plants every one or two weeks, using dilute liquid fertilizer, as instructed on the label. Don’t overfeed – it does more harm than good – and don’tnewly bought or re-potted plants. and Stag’s-Horn Fern appreciate a ‘foliar’ feed: spray dilute liquid fertilizer directly onto the . Pelargoniums always flower better when underfed.
House plants need varying amounts of water – Desert, for example, need less than Umbrella Plant. Whatever the maximum amount of water is for a particular plant, summer is usually the time to give it. For most house plants, this means thoroughly, then letting the top lcm ( 1/2 inches) mixture dry out before again.
Increase humidity and ventilation Plants that like moist air need higher humidity, the hotter it is. In summer, people sprayfloors and staging with water, or ‘damp them down’, to increase humidity. You can’t do that in your home, but you can increase humidity locally around tropical and thin-leaved plants.
Place the pot in a larger pot and fill the space between with damp peat.
Group plants on a gravel filled-tray kept topped up with water.
Open windows on humid days, so the E plants benefit from the humidity.
A Opening the windows also gives house plants the fresh air they need. If it’s stuffy for you indoors, chances are, it’s also stuffy for the plants! Avoid draughts, which dry out leaves.
Place plants outside
After the last frost, place the house plants listed on the back cover in a sheltered spot outdoors. The sun helps ripen the woody growth, so they flower or fruit well the following season. Rain washes the dust off the leaves and increases the humidity, and fresh air helps ripen wood and build up the plant’s resistance to pests and diseases. Keep an eye on the weather and avoid placing plants near corners where they could blow over.
Shade plants from hot sunlight
If you haven’t already done so, move all plants exceptand succulents away from south-facing windowsills; or put up net curtains, to filter the light. Outdoors, provide light shade for house plants, too, except for and succulents. Remember that plants on a sunny get extra heat and light reflected off the paving.
Watch out for pests

Check, too, the undersides of any curled or disfigured leaves. If you discover pests, move the plant to an isolated spot.
Patio plant care
Most of the summer tasks for house plants apply to patio plants, too – especially generous watering and. Pots and window-boxes may need watering several times a week, or even once a day. Hanging baskets may need watering twice a day. The smaller the , the more often it needs watering; peat-based mixtures dry out quicker than loam-based ones. If you go on , move the plants to a shady spot, if possible, and ask a neighbour to check on them every few days to see that they are safe and healthy and have not dried out from lack of watering.

With Tomatoes, nip out any shoots that form where branches meet the main . Once the tiny fruits are visible on the bottom truss, feed weekly with special Tomato fertilizer. Once six trusses form, pinch out the top; as the fruit ripen, remove a few of the lower leaves.
Many plants look their best now, but as well as enjoying them, you should help them make the most of summer by giving them special attention.
