July in the flower garden

It’s July, time when the roads get busier with holiday makers and time to retreat to the sanctuary that is the garden.

When it is warm, continue to hoe weeds, as they will shrivel and die on the surface. Likewise, if you see any larvae or adult pests pick them off, squash them or use a suitable control method. Scarlet Lily beetles are particularly a pest at this time of year.

Pruning

If you have any variegated shrubs, cut out any non variegated branches, making your cut at the base of the stem where it joins the main trunk. Many variegated shrubs will try and revert to their mono colour if not managed in such manner.

Prune deciduous magnolias if required but always leave at least 75% of the original canopy.

Prune your early flowering shrubs like Weigela taking them back to well placed side shoots.

Cut back hardy geraniums after flowering to encourage them to re-flower or grow fresh foliage.

Watering

Continue to harvest rain and use your water butts to water plants like agapanthus, camellias and rhododendrons as they will be setting their buds for next year.

You should also water clematis, roses, laurel and honeysuckle in dry weather to discourage powdery mildew.
