Quick Answer:

Sterilizing your soil, pots, and trays is essential when starting seeds in a greenhouse to prevent disease, improve seedling survival, and create optimal growing conditions—use commercial seed starter mixes, sterilize reused containers with bleach, and consider homemade sterile blends or soil baking for best results.

Sterility in the greenhouse sounds somber but in a few instances, it truly matters and saves gardeners from hassle and disappointment. Here is where I heed caution.

Quick Answer:

Elevate the beauty and biodiversity of your vegetable garden by planting fragrant Sweet Pea ‘Matucana’, vibrant Clary Sage, and long-blooming Hummingbird Mint—three easy-to-grow annuals that attract pollinators, complement edibles, and flower from summer through fall.

Last Summer I realized My little food garden was looking dull- prolific - but dull. To remedy the tedious rows, I decided to try three uncommon annuals to improve the appearance. To my surprise, they all flowered for five months. These plentiful flowers did so much to spiff up the vegetable Greenhouse Garden that this summer, they've made their debut in the flowerbed.

We really do build greenhouses in any custom color! This periwinkle greenhouse was shipped to Oregon and the picture are from during that installation process. Would you pick a color as wild as this one? Or something more classic?

BC Greenhouse Builders recommends placing your greenhouse for maximum year-round productivity:

Forcing Bulbs

For the friends with the winter blues, or being impressive on Valentine's Day, consider forcing bulbs. "Forcing" sounds ruthless, but it's the process of condensing the bulb's winter and spring, so the flowers bloom in early winter instead of mid-Spring. A greenhouse makes this easy, and foolproof.

This is the new rooftop greenhouse at Indiana Wesleyan University during the installation phase.  At 28x75 feet long, this commercial rooftop greenhouse will serve the Division of Natural Sciences.   Greenhouses for schools are certainly a growing trend and we are happy to be a part of this new exciting project for IWU!

Quick Answer:

Think fertilizing is optional? Think again. Even the laziest greenhouse gardeners will see bigger blooms, healthier seedlings, and more resilient plants with the right fertilizer routine. Whether you’re starting cuttings or transplanting seedlings, container-grown plants need consistent nutrients due to frequent watering and limited soil volume. A simple system—like color-coded watering cans and diluted fertilizer solutions—makes regular feeding easy and effective. By using a light but frequent approach, even busy or forgetful gardeners can ensure robust root growth, reduced transplant shock, and thriving greenhouse plants from season to season.

Truth be told, I can easily ignore a bit of soil spilled on the benches or an occasional unsterilized pot for seedlings. I don't always wear gloves, or fastidiously wash labels. I like the results in my greenhouse. My Sweet Peas bloom early, my tomatoes grow fat on the vine. A little mess, a few germs - my plants and I are no worse for the wear.

We recently helped out some customers who had purchased one of our greenhouses secondhand! The greenhouse was fully functional and they only needed a handful of new vents and screws. But other than that, it looks to be in pretty great shape! They were very happy with their purchase and we love seeing our greenhouses continuing to get love years after they are originally sold.

One of our favourite BC Greenhouse Builders projects! This Greenhouse that we built and went on sight to install is a 17x46 custom greenhouse for a public school in Brooklyn (PS216) as part of The Edible Schoolyard Project. The greenhouse is the heart of the classroom whereby the students will be gardening in a kitchen classroom setting that provides a hands-on environment for students in which to apply skills learned in traditional math, science and humanities classes.
