Everything You Need For Your Backyard Greenhouse To Take OffVIA MERCHANT

When it comes to current lawn and garden trends, backyard greenhouses are the latest obsession—and for good reason. The structure allows you to cultivate vegetables and other plants in a temperature-controlled, enclosed environment that’s safe from harsh weather conditions and pesky pests. But you need the right greenhouse accessories for a successful setup.

Different types of greenhouses are suitable for different types of yards. If you have the space for it, a large glass greenhouse could be the way to go. But if you’re working with a small yard (or just beginning as a greenhouse gardener), then this portable greenhouse on Amazon might be the one for you. Portable greenhouses and cold-frame greenhouses are smart options for those with smaller living spaces, like apartments.

Whichever greenhouse route you decide to go, there are a few must-have greenhouse accessories you’ll need to get your greens growing. From a greenhouse heater to outdoor grow lights for a greenhouse, we’ve rounded up all the essentials you’ll need for your backyard greenhouse to take off.

Greenhouse Heater

A heater is one of the most important greenhouse accessories. To keep a greenhouse frost-free, the temperature must remain above 32 degrees Fahrenheit. During colder months, it’s wise to use a greenhouse heater to keep plants from freezing. This Bio Green model heats spaces up to 120 square feet and comes with a digital thermostat. It’s made of durable stainless steel and is splash-proof, so you don’t have to worry about watering around it. Best of all, it’s inexpensive to operate!

Greenhouse accessories are extremely helpful for keeping your flora and fauna organized. We like this freestanding metal shelving unit for stacking all your outdoor plant pots. It’s simple, takes up minimal space and you can check on all your seedlings without moving them around, thanks to the three, four or five tiered shelving options.

T-Type Garden Waterproof Plant Labels via merchant

Plant Labels

Once you begin filling up your greenhouse with vegetation, you’ll need a way to keep track of what you’ve potted. These plastic plant labels are reusable and waterproof, making them ideal greenhouse accessories. We like the way the black labels look because they don’t take away from the flora, but there are also white and multicolor packs if you prefer another hue.

This salsa grow kit, one of our favorite greenhouse accessories, provides seeds for all the fixings needed to make fresh salsa: Roma tomatoes, jalapeños, verde tomatillos, cilantro, scallions and beefsteak tomatoes. Packaged in a recycled egg carton, the seeds can be transferred to larger pots once they outgrow their initial home.

Self-Watering Seedling Starter

Resembling an egg carton in design, this self-watering seedling kit is perfect for starting your garden patch from scratch. Just add soil and seeds to each well, then pour a little water into the base. The porous terra cotta wicks water from the reservoir to provide the seedlings with just the right amount of moisture. You only need to refill the base about once a week to grow plants from the seeds.
