Tips for July and August 2020, writes Elizabeth Kirton :
All that planning and preparation is worth it in July and August. Now you can harvest raspberries, currants, gooseberries and freeze any surplus to cheer up winter menus. By the end of August, the apple and pear harvest can begin; these fruits can be stored on trays in newspaper.
Thanks to the heat and lack of rain in June, beans, peas and early potatoes have not thrived, but will be ready for harvest and the annual courgette glut is under way.
When garlic leaves turn yellow, lift the bulbs and dry in a single layer in a dry place.
Sow seeds for autumn and winter salads.
This is a popular plant with bees – Echinops ritro ‘Veitch’s Blue’
Clip, snip and cut
- Early summer flowering shrubs like Philadelphus: cut back flowered stems to a strong lower shoot and remove one fifth of the old woody stems.
- Clip privet, box, yew, cypress and other ‘hedgy’ plants now the birds have finished nesting in them.
- Cut long whippy shoots of Wisteria to 5 leaves from the main stem.
- Prune out flowered stems of rambling roses; thin out the vigorous new growth and tie it in.
- Summer-prune cordon or espalier apples and pears
- Cut non-flowering side branches of grape vines to 5 leaves and fruit- bearing branches to 2 leaves beyond the fruit bunch.
- Cut back hardy geraniums to the ground after the first flush of flowers to get fresh foliage and more flowers later on.
- Dead-heading keeps perennials and bedding plants flowering for longer.
- In August, trim lavender, leaving an inch (2.5cm) of new growth
Propagate
- Take semi-ripe cuttings from shrubs – use the current season’s growth, cut below a node, remove the soft tips and place in gritty compost.
- Divide bearded irises and plant the young rhizomes 12inches(30cm) apart.
- Use strawberry runners to supply new plants for next year
- Collect seeds from perennials and hardy annuals as they ripen; store in paper envelopes (labelled!) in a cool dry place until spring
For your diary
Church Crookham Garden society has its annual show scheduled for 22nd August, but it is unlikely that we will be able to use the hall by then. We shall keep you informed.
