Preparing your greenhouse for fall involves maintaining appropriate night temperatures for different plants, thorough cleaning to prevent pests and diseases, and proactive pest management using safe insecticidal soaps, sterilized soils, and yellow sticky traps to ensure a healthy growing environment.
With convenient access to water and power and designed to maximize the heating benefits of your home, the attached greenhouse is a must for those wanting to extend the season and enjoy the view into the garden. BC Greenhouse Builders offers a lean to greenhouse kit and a gable design for home-attached greenhouses. A lean-to is a roof that has a single slope with its upper edge adjoining a wall or building. A gable-attached greenhouse is a typical freestanding greenhouse with the gable end removed and attached to a wall.
How Does a Greenhouse Save Your Garden from Climate Challenges?
A greenhouse protects your garden from unpredictable weather, extends the growing season by one to two months, and shields crops from pests like slugs and marmots through controlled heat, water, and shelter. Unlike outdoor gardens affected by heavy rains, cold snaps, or short seasons, a greenhouse offers consistent conditions that support reliable growth and higher yields. Whether you're overwintering perennials, growing year-round vegetables, or simply avoiding climate chaos, a greenhouse provides a practical, long-term solution.

What Are the Tips to Maximize a Bumper Harvest?
To maximize your fall greenhouse harvest, start fast-growing crops like radishes, spinach, and mustard in late summer, and experiment with resilient plants like sesame for high yield with minimal water. A greenhouse extends the growing season beyond outdoor limits, especially in northern climates, allowing gardeners to produce fresh food well into fall. By donating excess produce, greenhouse growers can also support food security and uphold the human right to access fresh, healthy food.

Fivewall polycarbonate is a durable, energy-efficient glazing option with high insulation (R-value 3.03), 62% light transmission, and excellent structural strength—making it ideal for cold climates, snow loads, and year-round greenhouse gardening.
BC Greenhouses has been working with this glazing product for a few years. It was so impressive in terms of its energy efficiency that we built a new aluminum framing system to accommodate the wider profile. For example, a typical single glass greenhouse glazing is 3mm in thickness whereas the Fivewall polycarbonate is an impressive 16mm.
Growing prize-winning tomatoes requires a greenhouse for earlier ripening and protection, careful late-summer pruning and low-nitrogen fertilization with calcium, consistent watering, and good air circulation to produce healthy, blemish-free fruit ready for competition.
My tomatoes are sitting beside me in the front seat of my shiny black station wagon. We are on our way to the fair!

I called Rodney a year after his greenhouse was installed. I expected him to brag about the size of his tomatoes or the hours he spends sitting and enjoying the beautiful space he created.
