LATE AUTUMN / OBSERVE & PROTECT
November in an
unheated greenhouse.
Shorter days mean slower growth. Care for what is actually there.
Three priorities
- Inspect leaves and stems for pests, mould or damage.
- Keep safely accessible glazing clear enough to admit daylight.
- Pick modest outer leaves only from well-established suitable crops.
Before you start
A quiet greenhouse is not a failed greenhouse. Growth follows the daylight.
Check which crops are actually present, their stage of growth and the instructions for their varieties. Move a job if its conditions are not met. A blank harvest record is more useful than an invented success.
A useful five-minute inspection
Look at moisture, temperature and new growth. If foliage looks damaged, inspect both sides and take a clear photograph before deciding on a treatment. Water the growing medium only when needed.
