Use water butts as much as possible and water your containers and baskets well in hot weather. Start to feed them with a balanced liquid fertiliser every 2 to 4 weeks.
Make small 'wells' around individual plants so that the water can soak the soil to about 25cm (10in). Merely wetting the surface wastes water, encourages weeds and can lead to surface rooting making plants more vulnerable.
Keep removing blanket weed from your pond to allow the plants and fish room to breathe.
Keep an eye out for white powdery mildew on plants. If possible, remove the affected parts and spray with a fungicide to prevent further spread.
Look for aphids on the underside of leaves - rub them off by hand or spray with an insecticide to prevent them multiplying. Alternatively try using a natural pest control such as Lacewing larvae
Keep an eye out for scarlet lily beetles on your lilies - remove and crush any you see. Also check for the sticky brown larvae on the underside of leaves.
Check for vine weevils by tipping your plants out of their pots and looking for 'C' shaped creamy maggots amongst the roots. Treat with nematodes if vine weevils are spotted.
Invest in pest control to prevent slugs attacking your young plants.
Clip evergreen hedges such as privet, box and yew while they're in active growth.
Open greenhouse vents and doors on warm days.
Check plants in your greenhouse daily and water them if the soil is dry.
Damp down your greenhouse on hot days to increase humidity and deter red spider mites.
Turn the compost in your bins every month to keep it well aerated.
Keep bird baths topped up in hot weather.
