Greenhouse gardening can be accomplished in much the same way as field planting. It's just that planting and growing occurs in a confined space, and there are some specific considerations that must be addressed. Whether you sow seeds directly in the soil, transplant seedlings into raised beds, cultivate orchids in individual pots, or germinate mushrooms in bags in your greenhouse, you will want to follow prescribed practices for the plants that you choose to grow. There are some advantages to each kind of planting. For instance, you can grow citrus fruits or tomatoes in large pots under greenhouse cover or string vining plants like beans and some flowers on trellises that extend from the ground upwards to the ceiling. Planning what to grow and how to make use of available space is an important part of greenhouse planning.
Some low-growing plants might benefit from the shade provided by taller adjacent plants, and intermixing flowers with some vegetable plants can help control pests. A basic knowledge of effective gardening principles is important whether you have a greenhouse or you plant a traditional dirt garden. Raised beds are particularly adaptable to greenhouse growing. Water requirements, of course, will vary based on the crops you choose. Misters, drip irrigation or automatic sprinklers can be utilized in a greenhouse to ensure that plants receive the proper amount of water, but typically greenhouse growing will require a bit less water than open field growing.
