The Ornamental Garden in July


This month is mainly about keeping the garden neat and tidy by deadheading spent flowers, and pruning and supporting wayward plants when requied.

It is also about ensuring that plants don't lack for Food and Water, and that they are free from Pests and Diseases.

Note: As with most advice on gardening the advisors location will often influence the content of the advice.

To alleviate this problem I have produced this chart indicating how you can make adjustments to the timing of events as seen in this website.

I hope you find this useful! .......Tg
