In The Greenhouse and Around The Garden This September

Water greenhouse plants early on in the day so the greenhouse is dry by the evening. Damp, cool nights can encourage botrytis.

Improve clay soil before it becomes too wet or frozen by incorporating organic matter and/or horticultural grit.

Close greenhouse vents and doors late in the afternoon to help trap in heat overnight. This will ensure your plants crop for as long as possible.

Clear pond weeds and net your pond in anticipation of autumn leaf fall.

Clean out your greenhouse to reduce the risk of pests and diseases next year.

Install water butts to collect rain this autumn and winter. Rain water is great for watering ericaceous plants such as blueberries, rhododendrons and camellias.

Remove shading from your greenhouse towards the end of the month so that plants get the maximum light available.

Raise pots off the ground for the winter by using bricks or ‘pot feet’ to prevent waterlogging.

Top Tip:

Create compost bins in preparation for all the fallen leaves and dead plant material which you’ll be collection over the coming months. Autumn leaves make a great addition to compost bins and are ideal for making leaf mould. 


This Month's Key Tips
  • Plant spring flowering bulbs.
  • Net ponds before leaf fall gets underway.
  • Pick autumn raspberries.
  • Keep up with watering of new plants.
  • Plant trees and shrubs in autumn - will give them the best start to let the roots settle in before new spring growth.
