A: It depends on what you want to grow. If you want to grow plants year-round in a cold climate, a greenhouse heater is necessary. If you just want to extend the growing season by a few weeks, an unheated greenhouse is usually fine.
A: Glass is beautiful and lasts forever, but it’s heavy and can break. Polycarbonate is a great option for beginners because it’s shatterproof and provides better insulation (retaining heat inside the greenhouse better).
A: Use shade cloth, open all greenhouse ventilation points, and consider a solar-powered fan to keep the greenhouse air moving.
A: Yes! By using a greenhouse, you can grow cold-hardy crops like kale, carrots, and leeks throughout the winter, even without a heater, as long as you provide some extra insulation.
No, most mushrooms don’t. Oysters, Lion's Mane, and Shiitake need a little light to develop their colors and shapes properly. A kitchen counter away from direct sunlight is usually perfect.
While possible through "cloning," it is difficult for a beginner. It is much more successful to start growing using a mushroom kit or purchased spawn from a reputable supplier.
Pink Oyster mushrooms are the speed champions, often ready for harvest within 3 to 5 days of the first "pins" appearing.
The primary benefit is pest control. Onions repel a wide variety of pests, including aphids, carrot rust fly, onion flies, and beetles due to their strong sulfur scent. This helps protect nearby vulnerable plants.
No. You should avoid planting onions near legumes like peas and beans. Peas fix nitrogen, but onions can interfere with this process and inhibit the growth of the pea plants. Asparagus is another plant that does not grow well together with onions.
Yes, onions grow best in full sun. However, they can tolerate some partial shade provided by taller companion plants like tomatoes or peppers, especially in very hot climates.
If you have ever felt the frustration of a killing frost ending your harvest too early, or the disappointment of leggy seedlings struggling on a windowsill, then owning a greenhouse is the solution you have been searching for.
Imagine walking into a warm greenhouse while the outside air is still biting with the chill of late winter. Inside, the air is humid, the scent of damp earth is rich, and rows of vibrant green vegetable starts are reaching toward the glass. This isn't just a dream for professional farmers; it is entirely achievable for the beginner gardener. Whether you have a sprawling backyard or just a small patio, greenhouse gardening offers a way to take control of the climate and grow crops that would otherwise never survive in your local hardiness zone.
In this comprehensive beginner’s guide, we will explore every facet of greenhouse gardening 101. We will cover what these structures are, where to put them, how to choose the right greenhouse, and—most importantly—how to keep your plants in a greenhouse thriving through every season.
To understand greenhouse growing, we first have to understand the structure itself. A greenhouse is a framed structure covered with a transparent or translucent material—usually glass, polycarbonate, or plastic film. It works by trapping solar radiation. The sunlight passes through the greenhouse roof and walls, warming the soil and plants inside. This heat is then trapped by the structure, creating a microclimate that is significantly warmer than the ambient outdoor temperature.
New to greenhouse growing? You’ll quickly find that a hobby greenhouse offers benefits that traditional open-air gardens simply cannot match.
Siting a greenhouse is the most important decision you will make. You cannot simply plop a greenhouse kit anywhere and expect it to work. Make sure your greenhouse is positioned to maximize its efficiency.
For greenhouse gardening, light is your primary fuel. Ideally, your greenhouse should receive at least 6 to 8 hours of direct sunlight during the winter months.
The greenhouse floor must be level. If the ground is sloped, the greenhouse frame will eventually warp, leading to cracked glass or doors that won't shut. Additionally, ensure the site has good drainage. You don't want water pooling inside the greenhouse or around the foundation, as this leads to high humidity and root rot.
Don't put your small greenhouse so far at the back of the property that you dread walking to it.
When choosing a greenhouse, consider your goals. Are you just starting a greenhouse garden for a few herbs, or do you want to provide vegetables all year round for your family?
The "when" depends on your climate, but for most greenhouse gardening 101 enthusiasts, the calendar looks like this:
Greenhouse gardening is different from outdoor gardening because the environment is contained. You should almost never use "garden soil" from your backyard in pots inside the greenhouse.
If you are new to greenhouse growing, start with these reliable performers:
Owning a greenhouse means you are the "Weather God." You control the rain, the wind, and the sun. This requires a bit of daily maintenance.
Because a greenhouse can become very warm, plants dry out much faster than they do outside.
Greenhouse ventilation is arguably the most neglected part of greenhouse gardening 101.
Inside the greenhouse, the lack of natural predators (like ladybugs or birds) means that a few aphids can quickly become a plague.
