How to Choose a Greenhouse for Your Space

Most gardeners would love to own a greenhouse. This appeal may be strongest in cold climates, but being able to grow an endless supply of sturdy little seedlings is a pretty appealing concept no matter where you live.

And what gardener isn't intrigued by the idea of having a tropical environment filled with orchids, citrus and jasmine; or wouldn't relish the opportunity to pick fresh salad greens and vine-ripened tomatoes on a cold winter day.

There are now dozens of affordable, well-constructed greenhouses on the market, as well as a full range of accessories that make greenhouse gardening easier than ever.

Consider Function

An attached greenhouse or sunroom is the right choice if you want a place to read and putter among potted plants.

For starting seeds, a freestanding polyethylene-covered hoop house can probably give you everything you're looking for.

If your objective is to have a nearly year-round supply of fresh greens and herbs, you may want to consider a solar greenhouse that requires little or no supplemental heat.

Can you imagine yourself tending an extensive collection of orchids, propagating begonias and experimenting with oleander and passiflora? If so, you'll want a well-insulated, professional-quality greenhouse that can be temperature-controlled year-round, with running water, a power source for supplemental lights, active ventilation and plenty of room for expansion.

Consider Appearance

Appearance may also be an important consideration. Will you be happy with a polyethylene hoop house, or is it important that your greenhouse be a more aesthetically pleasing addition to your home and your landscape?

Consider Location and Climate

Climate and location are crucial considerations. One reason greenhouses are so popular in England is that their climate is far more moderate than what most of us must cope with here in the U.S. Operating a year-round greenhouse in Vermont or Minnesota usually requires an insulated foundation, double glazing, insulating shades, buried power and water lines, and a serious financial commitment for heating.

In the summer, maintaining a plant-friendly environment may require shade cloth, multiple fans and a misting system. But people who do have a greenhouse, and have tasted the pleasures of being able to fuss around in their own warm, plant-filled jungle, would be quick to argue that the benefits outweigh the challenges.
