An overview of winter greenhouse growing has been covered in our December 2023 blog post, but it seems worthwhile to expand the conversation of winter growing in a home or hobby greenhouse this month as well. For one thing, a greenhouse is not the end of the story. A few other accessories and ideas will make you a more successful grower this winter. 

Recognize the Signs of Plant Stress

Quick Answer:

How do I revive my plants and know if they need fertilizer? Yellowing leaves, pale color, and stunted growth are common signs of nutrient deficiencies—especially nitrogen and sulfur—while shiny, vibrant leaves indicate a well-fed, thriving plant. Are compost, worm tea, and manure enough to fertilize greenhouse plants? Though compost, worm castings, and manures improve soil texture and microbial health, they lack essential nutrients and should be paired with a balanced fertilizer for full plant recovery. What other issues might be stressing your greenhouse plants? Inconsistent watering, pest infestations like scale, or high pH levels can also cause symptoms of stress; identifying the root cause and responding with steady care, micronutrients, and natural pest control helps restore plant vitality and resilience.

How Do You Prepare Your Greenhouse for Spring?
Preparing your greenhouse for spring involves starting seeds and cuttings of both cold-tolerant and heat-loving plants, organizing space by moving or harvesting early crops, and timing indoor planting according to local frost dates. Efficient greenhouse management—rotating crops, repotting, and maximizing space with shelves—ensures continuous harvests and healthy plant growth throughout the season. Beyond growing food, a greenhouse provides a year-round sanctuary that nurtures both plants and gardeners.

Starting Seeds and Cuttings for Your Greenhouse Garden

It’s really, truly spring and the neighbours are jealous. They don’t have a greenhouse, so getting ready for spring in their gardens is all about buying high-cost overgrown plants from commercial greenhouses.

How does nature in a greenhouse benefit health and well-being? Greenhouse gardening fosters year-round growth, creativity, and mental wellness. The greenhouse serves as both sanctuary and studio, where finger limes, tomatoes, and microgreens thrive—and where the act of nurturing plants inspires everyone from camera crew to casual observers. As supported by experts like psychiatrist Susan Stuart-Smith, engaging with natural complexity in gardens has proven restorative effects. Whether it’s growing exotic citrus or saving tomato seeds, greenhouse gardening extends the seasons and deepens our connection to nature—reminding us that the seeds we sow today hold the promise of tomorrow’s blooms.

Late Fall Harvests

It's late September and I taste my first-ever finger lime, grown right in my greenhouse, and I am amazed by the crisp texture and luscious lime taste of the juicy vesicles. (See my first impressions here) And just then an unrelated email arrives. A Los Angeles-based marketing firm asks, "Will you showcase the benefits of nature on behalf of a client for an online event?"

Quick Answer:

Want to kickstart your greenhouse garden this season? The best time to begin is now. Cool-weather crops like arugula, bok choi, spinach, and radishes thrive in early spring greenhouse conditions—even in unheated spaces. Warm the soil with heating cables or IRT mulch to speed up germination and enjoy a head start on the growing season. Greenhouse gardening in late winter or early spring also means fewer pests, like flea beetles. While heat-loving plants like peppers need more warmth to sprout, starting them indoors on a damp paper towel can ensure strong, healthy transplants later. With the right timing and a simple crop schedule, your greenhouse can produce fresh greens and veggies year-round.

What Are the Tips for Growing Greenhouse Tomatoes in the Heat?
To prevent heat stress and flower drop in greenhouse tomatoes, use 40-70% shade cloth to reduce temperature and light intensity, maintain good air circulation with fans and open screen doors, and regularly water soil and paths to cool the environment and increase humidity. Selecting heat-tolerant tomato varieties, like smaller-fruited types or proven heirlooms such as Juliet and Cherokee Purple, helps ensure fruit set during hot spells. Combining these strategies allows growers to maximize tomato yields and extend the harvest season even in extreme summer heat.

The Trouble with Greenhouse Tomatoes

Do your greenhouse tomatoes have heat stroke?

If your tomato blooms are bending and falling off, flower and all, they are having a heatstroke. When extreme heat hits, greenhouse tomatoes fail to set fruit even as the leaves keep growing and new blooms appear.
