Propagating Tasks in May
The bulk of the propagating tasks under glass will be nearing completion now, apart from perhaps some pricking out, and potting up of of late sowings and cuttings.
However! this does not necessarily mean it is the end of propagating, as the soil outdoors will be beginning to warm up now thus allowing propagation to take place by means of Insitu sowings and Plant division.
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
