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

Growing 'Indoors' or 'Under glass' in March


On bright days temperatures can rise rapidly so provide adequate ventilation.

Ensure seedlings and other delicate plants are shaded from direct sunlight.

Increase the watering and feeding of established plants.

Soft plant growth will encourage feeding pests so regular plant inspections shoud be made to alleviate this problem.

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
