What to do
* Vigorous pruning is needed on wistarias to stop long new tendrils creeping in under tiles and through windows.
* Apple and pear trees trained in cordons, espaliers and fans may need summer pruning. Do this gradually so the tree doesn't suffer too much of a shock.
* Layer border carnations. Choose young side shoots that have not flowered and nick through the joint at the base of each shoot. Do not cut it completely. Bend the side shoots down and peg them firmly into the ground with a bit of bent wire. Cover the split stem with fine damp soil and keep the plant well watered. The layers should root by early September.
* Start planting autumn flowering bulbs such as colchicum and sternbergia.
* Continue to dead head petunias, roses and osteospermums.
* Goose grass has been particularly aggressive this year. Haul it away to the bonfire before it drops its seeds for next year's crop.
* Continue to nick out side shoots of tomatoes and tie the main stem onto its support if necessary.
