A greenhouse lets you start seeds weeks earlier, protect tender plants from frost and keep harvesting long after the outdoor garden has finished. From portable greenhouses for a patio to large walk-in kits for serious growers, there's a size for every yard and budget.
Types of greenhouses
- Polycarbonate greenhouses use rigid panels on an aluminum or steel frame. They hold heat well, diffuse sunlight evenly and stand up to wind and snow, making them a long-term investment.
- Walk-in tunnel greenhouses use a PE cover over a steel frame. They're affordable, quick to assemble and give you plenty of growing room.
- Portable and mini greenhouses with shelving fit patios and balconies and are ideal for starting seedlings.
- Low tunnels cover garden rows to protect crops from frost, pests and heavy rain.
How to choose
Start with what you want to grow and how much space you have, then leave room to expand, since most gardeners wish they had bought bigger. Look for roll-up doors, windows or roof vents for airflow, because good ventilation prevents overheating and disease on sunny days. In windy areas, choose a sturdy frame and anchor it securely to the ground.
Getting the most from your greenhouse
Place it where it receives as much sun as possible, ideally on level ground with good drainage. Add shelving and grow lights to make the most of the space, and pair it with raised garden beds for an efficient, productive garden all year.
