If you have a smaller garden than you would like it is still possible to have a greenhouse. Greenhouses are so great because you can grow plants you might not be able to normally because the weather is too cold. If you want a green house for a small garden then you should shop around for a portable green-house. They are easily stored away during the winter when you probably don’t use it anyway. They are lightweight and well made but there is the risk of them blowing ways in storms so tie them to something like a wall.
