The Gardeners Almanac

The place to find out what to do in the garden this week

Growing 'Indoors' or 'Under glass' in August


Basically this month in the greenhouse is about ensuring that plants don't suffer from extremes of heat.

Keep the greenhouse well ventilated.

Ensure that plants are well watered and fed, and don't sit them in direct sunlight as the sun's rays through glass, can cause leaf scorch, or worse.

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
