Hints and Tips for July – August 2022

Liz Kirton writes:

Gardening is a hobby that can bring great joy! In June I have seen a wonderful display of irises, rambling roses and poppies – beautiful! BUT I have been much saddened by disease in the onion bed and box moth destroying my 20 year old box hedges.

Looking forward to July, the herbaceous border should be at its best – take a record of which plants need to be divided in the Autumn.

Currants, berries, potatoes, onions, peas and beans should be ready for picking and storing.

When garlic leaves turn yellow, lift the bulbs and dry in a single layer in a dry place.

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 7 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.
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
