Growing 'Indoors' or 'Under glass' in December


Basically this month is about keeping plants ticking over, and ensuring that they are growing in optimum conditions.

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
