What is the point of a greenhouse?

Question

How does putting my plants in a greenhouse help them grow? Is it purely to shield them from cold weather, or are there other benefits?

Answer 1

There are several benefits of a greenhouse:

• accumulation of heat from the sun

• possibility to regulate temperature and humidity

• Protection from wind and excessive rain

• protection from unwelcome pollens

• limited protection from pests especially birds.

Typically you put in a greenhouse plants that prefer a warmer climate than the local one.

Answer 2

Primarily, greenhouses trap heat and moisture.

Most plants prefer things warm and damp, so it's an ideal environment for growing fruit and germinating seeds.

Answer 3

Green houses can extend your growing season, and even allow you to grow throughout the year.
