Quick Answer:

To optimize greenhouse climate control year-round, tailor your heating and cooling system to your location, crop types, and usage seasons—then enhance efficiency with proper glazing, insulation like bubble wrap, thermal mass (black barrels), energy curtains, and strategic air circulation.

When offering heating and cooling suggestions for optimum climate control for your greenhouse, we ask our customers three things:

Quick Answer:

To keep your plants safe in winter, use your greenhouse as a controlled environment by insulating with materials like bubble wrap, using energy-efficient methods such as partitioned zones or under-bench heating, and bringing more delicate plants indoors. Cold-hardy crops can thrive with minimal heating, and creative techniques like milk jug gardening or covered trays can extend your growing season. Personalize your setup to balance energy use, plant needs, and available space, turning setbacks—like a fallen Christmas cactus—into opportunities for propagation and resilience

Saturday Morning Startle

It’s 7 AM and I’m having coffee in my cozy rocking chair waiting for the sun to come up so I can walk the dogs.

Quick Answer:

To grow healthy plants in greenhouse pots, select the right pot size and material—using breathable options like terra cotta or fabric pots for moisture-sensitive plants—choose nutrient-rich soil suited to your crop, and refresh or repot plants seasonally to prevent root crowding and nutrient depletion, ensuring optimal growth and flexibility.

How do you grow?

Essentially there are two ways to grow in soil in your greenhouse. You can grow in pots or you can grow in planting beds. We look now at growing in posts, and we will consider the positives and negatives growing directly in the ground.

What Are the 5 Tips for Keeping My Greenhouse Toasty This Winter?
To keep your greenhouse warm and your plants thriving in winter, start by growing cold-tolerant crops and installing an electric plug with a thermostat to control supplemental heat from soil cables or space heaters. Add frost protection by layering Agribon fabric, build mini-insulated zones for tender plants, and use old-school lights or warming tools for targeted heat. Finally, keep air circulating year-round with fans to prevent cold pockets and strengthen plant growth.

Keeping Your Plants Cozy This Holiday Season

Imagine my surprise when a small hole we drilled through our greenhouse foundation became a runway for mice. We pulled an extension cord into my greenhouse through that hole and the tiny gap became a neon sign for rodents.

Quick Answer:

What are the best tactics to keep your plants alive in a winter greenhouse? Protecting plants in winter requires matching their cold tolerance to the right strategies, such as using row covers, fabric shelters, thermostatic heaters, and airflow management to create microclimates within your greenhouse. Tropical plants should be moved indoors before the first frost, while semi-tropical species like citrus and bananas can thrive under floating row covers and supplemental heat. Temperate and hardy plants—like kale, arugula, and geraniums—often survive with less protection, but benefit from insulation, moisture, and bottom heat for propagation; overall success depends on segmenting your space, monitoring temperatures, and applying targeted heating only where needed.

Row Cover, Fleece and Heaters 

All these items will help your winter greenhouse. 

Quick Answer:

What are the 6 essential tips for cleaning a greenhouse before winter sets in? The best time to clean your greenhouse is in late fall when plant growth slows, focusing on removing dead plants, reducing watering, clearing cobwebs, washing overwintering plants, and cleaning row covers to prevent pests and diseases. A thorough fall cleaning deters common greenhouse problems like mold, fungus gnats, and spider mites, ensuring a healthier growing environment for the upcoming season. Starting early and cleaning on a sunny day optimizes results and prepares your greenhouse for a productive spring restart.

Its never too early to get a head start

My husband and I planned a mid-week ski trip but on departure day I was still in my off finishing a time-sensitive project. We were staying overnight at the hill, it was still a workday, and the car was loaded up. There was no rush to get moving.

Quick Answer:

To extend your greenhouse growing season into fall and winter, begin a "cut and paste" routine: remove shade cloth to maximize light, clear out tired or unproductive plants, and replant with cool-season crops like spinach, bok choi, and lettuce in available gaps or containers. This proactive approach ensures a continuous harvest as light wanes and temperatures drop. By assessing plant performance and reseeding strategically, you keep your greenhouse productive and vibrant well into the colder months.

Some people consider the first day of school or even “back to school” shopping as the real start to fall. But for me and my garden, the first day of fall comes when wasps appear at my outdoor dining table and I am extending the greenhouse growing season.

Quick Answer:

Strategically rotate crops by seeding quick growers like radishes and greens alongside longer-season vegetables, using every opening in your greenhouse to maintain continuous harvests from early spring through late fall—without needing a rigid chart, just readiness and smart succession planting.

My crazy dogs

Corle ran ahead of me on the beach and stuck her head right into a dead seal. And then she took a big bite. 

Quick Answer:

Clearing greenhouse waste on a small scale involves chopping bulky plants into smaller pieces to speed composting, using tools like a chipper and rodent-proof compost bins such as the Speedibin for faster, pest-free decomposition. When animal assistance isn’t available, this method efficiently manages large volumes of plant debris, turning waste into valuable compost in about six months. Proper waste management not only keeps your greenhouse tidy but also supports sustainable gardening by recycling nutrients back into your soil.

Arnold is always hungry. And some of his favorite foods are the fruits and vegetables I grow in my greenhouse.  He also eats the plants of the tomatoes and squash I grow. He gently pokes around, licking up the small green fruits first and then chomps down on the whole tangled twisted plant.

Quick Answer:

How Much Food Can My Small Greenhouse Grow?
A small 8’ x 8’ greenhouse can produce a surprisingly abundant and diverse harvest by maximizing vertical and horizontal space with crops like microgreens, radishes, lettuce, tomatoes, and cucumbers, especially when supplemented with seasonal heating and grow lights. Crop selection and greenhouse heating significantly impact yield and growing seasons, allowing multiple successive harvests and year-round gardening possibilities. To optimize food production, gardeners should prioritize fast-maturing crops they love and efficiently use all growing areas, including shelves, pots, and hanging baskets.
