Garden greenhouses

A lasting growing space for border crops, staging and a full growing year.

Who is this type for?

A permanent garden greenhouse gives you more scope for trained crops, staging and year-round gardening. Choose a stable level base and a frame and glazing system suitable for the location. An unheated permanent greenhouse can still freeze.

Five things to check

  1. Measure the usable interior, shelving and door opening.
  2. Read the anchoring instructions and assess wind exposure.
  3. Check ventilation: you need to release heat on sunny days.
  4. Confirm replacement parts, glazing or covers are available.
  5. Include base work, delivery and assembly in the budget.

Choose around your plants

Seed trays benefit from staging; tall tomatoes need headroom and strong supports. Leave access for watering and for opening windows. Plan the space using the mature plants’ dimensions rather than the size of their nursery pots.
