JOBS AHEAD
Drop lawn mowing to once a fortnight in very warm, dry weather.
If you are going on holiday, ask a neighbour to water your plants or purchase an automatic watering system so your gardening efforts are not lost when you are away. See our other holiday-proofing tips.
Remember to stake taller plants, such as dahlias and lupins, as they will be growing quickly during this time.
Plants in flower beds and borders will need to be watered more regularly due to rising temperatures.
Hand-weed your borders to prevent weeds from becoming established, and check often for signs of any developing pest problems.
Picking the flowers of sweet peas every couple of days will encourage even more flowering.
Deadheaded any spent blooms around the garden to encourage new flowers.
Encourage tomato crops to grow by applying a liquid tomato feed every fortnight.
Spread a thick layer of mulch around moisture-loving crops such as broad beans and courgettes, as they will need even more hydration over summer.
There is still time to sow some peas and broad beans before the end of July, which will produce an autumn crop.
Remove any damaged and undersized fruit crops, and be on the lookout for any signs of fungal disease on leaves.
If some fruit crops are still ripening, cover them with a layer of fleece to prevent damage from birds and insects.
Strawberry runners can be pegged down into pots of compost to produce new plants towards the end of July.
Manage the temperature of the greenhouse with the use of shutters or shade paint, and open the doors regularly on hot days to increase ventilation.
Remember that greenhouse plants will dry out more quickly as temperatures rise, and most will require daily watering.
Watch out for common pests such as vine weevil and whitefly, which can be controlled by spraying the underside of leaves with a soap-based spray.
