The Ornamental Garden in October
Generally this month is about tidying up before winter sets in, and planting out various perennials, and shrubs before the soil cools down.
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
