An empty greenhouse looks spacious, but mature tomatoes can soon fill the path and doorway. Draw a route to the back plants and leave room for watering, tying in and harvesting. Position a propagation table where it gets light without shading mature crops for long periods. Allow for a door that needs to open fully and windows that remain accessible. In a polytunnel, also keep a clear route and access to ventilation. A compact greenhouse calls for fewer crops at once, as well as considering plant spacing.
From spring to autumn, sunshine can rapidly raise indoor temperatures. Ventilation and suitable shading where needed limit overheating. Check weather, windows and plants daily; automatic openers help but still need checking. Open roof windows and doors where structurally safe. For tunnels, consider wind and side-opening instructions. A slightly open door may not suffice for a full crop. Choose shading you can reduce when days darken.
Plants under roofs do not automatically receive rain. Check soil or pots and water roots directly. Indoor pots may dry quickly while densely planted beds stay moist longer. Do not retain one timer setting all season. Wet leaves and dense crops favour fungi. Monitor spacing and airflow and remove dead or affected material appropriately. Ventilation does not replace water, and extra water does not fix a bed remaining wet through poor drainage.
When a main crop finishes, remove old plants and inspect wires, ties, glass or plastic. Make space before planting another round. A clean workspace and pots reduce the spread of problems; the greenhouse does not need sterilising every week. Consider whether a cooler season allows suitable leafy crops or whether you want to repair the greenhouse first. Account for prolonged damp and frost: an unheated greenhouse is not automatically frost-free. Save a plan with actual plant sizes so next year involves less shuffling between a table, watering can and wall of leaves.
