FAQ for small greenhouses buyers:

Where should a small greenhouse be placed?

Rather than putting it in an exposed area of your garden where it could blow over, try and choose a position next to a wall or fence. For extra support, you could position other containers on either side.

Do greenhouses have to be in the sun?

Generally, a greenhouse should get full sun, especially during the winter. Site your greenhouse to avoid shadows from buildings & trees, since many plants do best in full sun. However, in especially sunny climates, high altitude areas, or for shade-loving plants, partial shade can be better.

What can I put in a mini greenhouse?

In Autumn time cuttings from fuchsias and geraniums can be taken to provide plant material for next year. Salad crops such as lettuce can be planted in the mini greenhouse to ensure a steady supply during the winter months. Vegetables such as Spring cabbage can be grown on ready for planting out.

Are plastic greenhouses any good?

Plastic greenhouses are very popular, as they are easy to put up, easy to clean, can be very cost-effective, and come in a good variety of shapes and sizes. However, despite an initial higher cost, wooden greenhouses are well worth considering.

When should I start plants in my greenhouse?

Because of this controlled environment, you can actually start seeds in greenhouses anytime. However, if you are starting plants, which you plan to transplant into gardens outdoors in the spring, then you should start the seeds in greenhouses 6-8 weeks before the last expected frost date for your location.

Should a greenhouse have a floor?

Greenhouse floors need to have excellent drainage. Floors can be made of concrete, stone slabs, brick, sand, or even dirt. Gravel floors provide excellent drainage and can be used in conjunction with a weed barrier to keep weeds from growing up through the rocks.
