In The Greenhouse This September
Water greenhouse plants early on in the day so the greenhouse is dry by the evening. Damp, cool nights can encourage botrytis.
Clean out your greenhouse to reduce the risk of pest and disease next year.
Empty pots, old compost and decaying plant material can harbour unwanted pests over winter.
Remove shading from your greenhouse towards the end of the month so that plants get the maximum light available.
Clean out cold frames ahead of autumn sowing and growing.
Top Tip:
Close greenhouse vents and doors late in the afternoon to help trap in heat overnight. This will ensure your plants crops for as long as possible.
