Growing Guide – December


Jobs To Be Getting On With

Continue to monitor the temperature carefully this month. Frost-free greenhouses should be kept at a minimum night time temperature of 5 – 7°C (42 – 45°F) and a maximum temperature of 13 – 16°C (55 – 60°F) during the day – any warmer may result in weak and lanky plant growth.

Some ventilation will be necessary to remove condensation and to keep the air moving inside the greenhouse. Do tackle this carefully though to avoid creating draughts that are prone to causing dangerous drops in temperature and killing plants; the advice given for the months of October and November will help you.

All should be relatively calm and peaceful inside the greenhouse this month, fitting the mood of the season. Take a look at our December Growing Guide for our gardening gift idea.

The very best relationship has a gardener and a flower. The gardener nurtures and the flower blooms.
