Planning a Greenhouse – What to Grow in Your Greenhouse

Choosing, Siting and Planning a Greenhouse

planning a greenhouse The type of greenhouse that you choose and the site that you select for it are both vital factors in providing a good environment for your plants.

Of course, not everybody has the chance to buy the perfect greenhouse, nor do they necessarily have the ideal place to put it. However, there are often adaptations that can be made, such as putting up wind-breaks, installing extra vents and insulation, or making benching that folds away.

Most important, with careful planning you can make sure that the plants you grow are suitable for your greenhouse, whatever its shortcomings. If you are just starting out, then check the chart below.

What will you use your greenhouse for?


Requirements and conditions

Raising annual plants for the garden

Good light early in the year. Benching with sand and capillary matting (you can get foldaway benching if you need the space later). A heated propagator is a great advantage.

Raising other plants from seeds and cuttings

Benching, as above. Shade in summer. A heated propagator will give you better results with a wider range of plants.

Growing tender summer vegetables, such as tomatoes

Soil borders are preferable. Good ventilation and light, and an efficient means of watering. A greenhouse with high eaves and glass to the ground is preferable.

Growing winter vegetables

Soil borders are preferable. Good insulation. During cold months of the year, some crops can be forced if placed under benching.

Growing fruit

Tree fruits usually need plenty of space and are difficult to fit into a small greenhouse with other plants. Growing trees in pots and moving them outside in summer is a possibility, but you will need a greenhouse with good access and a wide door. A vine is easier to accommodate (although it needs rigorous training), as are strawberries and melons. All need good light and ventilation.

Growing houseplants

Heat in winter is needed for many, but not all, common houseplants. Shading and sometimes humidity in summer.

Producing cut flowers, such as chrysanthemums

Chrysanthemums fit into a mixed greenhouse if grown in pots. Hardy annual flowers are best in soil borders. All need good light. Insulation extends the season.

Growing ornamentals for flowering in the greenhouse

You can find ornamentals and cropping plants to fit most greenhouses, although only foliage plants will grow in very shady conditions.
