July Gardener's Calendar

July often a hot and dry month can put a lot of stress on your garden. If you have any grey water and collected rain water, use it to give your plants a drink. Baskets can suffer in hot weather too and die if not watered regularly. This month enjoy the summer and your garden, but don’t forget there’s plenty to do to ensure you get the best from your plants.

 

 

 

Sowing and planting

July is the time to plant autumn flowering bulbs and order your autumn bedding plants.

When your early border flowers have finished and are starting to die down fill in the spaces with Cannas, Fuchsia, Cosmos and Verbena Bonariensis, all will provide colour and interest for the rest of the summer.

 

Tidying your garden

Dead head bedding plants and perennials to encourage and prolong flowering. Cut back and feed Delphiniums and Geraniums to encourage a second flowering period. 

Make sure tall perennials such as Lupins and Delphiniums are staked up and tie in climbers such as Roses and Clematis to trellis, fences, and walls.  Train new growth diagonally or horizontally to encourage more flower buds.

 

July Garden Maintenance

To save water mulch borders, a layer of 2-3 inches will help keep down weeds too.  Move pots and containers into the shade to stop them drying out so quickly.

Make sure you water well throughout July, rain is scarce and plants prefer a regular, deep soaking as this helps develop a strong root system.  It is best to water in the early morning before the heat of the day.

Hoe your borders, to ensure that weeds don’t take over if you go on holiday.  Perennials weeds are best dealt with in the summer when they are growing fast.  Try a weed killer or, if you prefer the natural approach, dig them out.

Protect

If Clematis suddenly collapse, this could suggest clematis wilt.  The foliage turns black and the veins take on a purple colour. Affected stems should be cut down to ground level and the remaining stems and the surrounding soil sprayed with a fungicide. 

Treat any black spots you may find on your Roses.  Black spot can be identified by black or brown patches on the leaves and the leaves will turn yellow and fall off.  If left untreated it will strip the plant of all leaves and eventually kill the rose.

 

Vegetables

This month sow Beetroot, Spring Cabbages, Lettuces, Spring Onions, and Rocket. You’ll need to keep them well watered so keep that in mind if the weather gets really hot.  

Harvest Garlic, Onions, and Shallots when the lower leaves start to turn yellow.  You can dry them outside if it’s dry and sunny or on an indoor windowsill.

Courgettes can be picked when they are about 15cm long and harvest your Peas and Beans. Carrots are ready when the tops of the carrots, which are visible, look like they are the right diameter.  Harvest Potatoes if they are ready.  New Potatoes are ready a week or so after the flowers appear and all other Potatoes are ready when the foliage starts to die and turn yellow.

At this time you should have plenty of ripe Tomatoes to pick. Keep the stalk intact and store at room temperature for the best flavour.

Harvest early Blackberries, Blackcurrants, Redcurrants and Gooseberries when they are slightly soft.  Once your Strawberries have finished fruiting you can cut them back to 2cm high. Most varieties crop well for only 3 years.
