Buying a Portable Greenhouse

Niki Jabbour, the author of “Growing Under Cover” and a writer for SavvyGardening.com, offers some sage advice on deciding which portable greenhouse is right for you: Consider carefully how you want to use it.

Will it be temporary frost protection overtop a garden bed? Or are you planning to start seedlings inside it this spring? Maybe you’re looking to create a microclimate around heat-loving summer vegetables like tomatoes, eggplants and peppers. Or perhaps you’re hoping to extend the harvest season into the autumn and winter months.

Regardless of your gardening goal, Jabbour says it’s important to pick the right portable greenhouse to achieve it.

Other factors to think about:

  • Size: Carefully measure the available space and select a portable greenhouse to fit it. “This is particularly important in urban areas where garden space for a large structure can be hard to find,” says Jabbour.
  • Placement: A sunny spot, sheltered from gusty winds, is ideal. Never place a greenhouse under trees or in the shade of nearby buildings.
  • Durability: “In Northern areas like mine, where we get a lot of snow in winter, it’s essential to have a greenhouse — portable or permanent — that can withstand snow load,” Jabbour says. Materials like powder-coated aluminum and steel tend to be stronger and more stable than cheap plastic. “There are a lot of options available online and at garden supply stores and an inexpensive structure made from polyethylene won’t be as durable as one made from polycarbonate or glass,” she says.
  • Design: Floorless models protect plants already growing and offer good drainage. A-framed or arched (walk-ins) let you cultivate tall plants.
  • Budget: The old adage “You get what you pay for” is also true for portable greenhouses. If you want a portable greenhouse to last for years, don’t go cheap. You can justify the expense when you consider the money you’ll save on your grocery bill.

Expand the growing season, protect vulnerable plants from frost and give seedlings a fighting chance with our picks for the top portable greenhouses.
