Propagating Tasks in September


There is still time to sow a few perennials and take a few cuttings.

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
