Let’s delve deeper into some of the best veggies you can cultivate during the winter:


In a greenhouse, potatoes find a haven from the harsh frosts that can damage their growth.

They prefer a cool environment, and with the right soil mixture and moisture levels, they can develop robustly.

The joy of digging up fresh potatoes in the heart of winter is unparalleled. Plus, there’s nothing like a homegrown potato to elevate your winter stews and roasts.

Winter lettuce

Salads need not be a summer-only affair.

Winter lettuce varieties, such as Winter Gem and Valdor, can provide you with crisp, fresh leaves even in the colder months. These varieties are specifically bred to withstand lower temperatures.

In the protective cocoon of a greenhouse, they can grow without the threat of frostbite, ensuring you have fresh greens for your winter salads.

And let’s be honest, there’s something quite satisfying about plucking fresh lettuce leaves while snow blankets the world outside.

Pak choi

Also known as bok choy, this Asian green is a delight in stir-fries and soups. It’s not just its flavor that’s impressive; Pak Choi is also a trooper when it comes to colder climates.

In the controlled environment of a greenhouse, it can grow steadily, providing you with its crunchy, leafy goodness throughout the winter.

Plus, it’s rich in vitamins A, C, and K, making it a nutritious addition to your winter meals.

Spinach and kale

These two are the superheroes of the vegetable world. Packed with nutrients and known for their health benefits, spinach and kale are must-haves for any greenhouse gardener.

They’re cold-hardy and can produce leaves continuously, even in lower light conditions typical of winter.

Whether you’re making smoothies, soups, or simply sautéing them with some garlic, these greens will ensure you’re getting your dose of vitamins and minerals.

Cabbage and broccoli

Both members of the Brassica family, cabbage and broccoli, are winter favorites. They’re robust, versatile, and packed with flavor.

In a greenhouse, they can grow without the constant threat of pests like cabbage worms.

By providing them with a steady supply of nutrients and ensuring they’re adequately spaced, you can look forward to a bountiful harvest. Imagine fresh broccoli florets in your pasta or a crunchy cabbage salad, all from your winter greenhouse garden.

Brussel sprouts

Often a divisive vegetable on the dinner table, but when homegrown, even the skeptics can be converted. Brussel sprouts are like mini cabbages and are perfect for roasting or steaming.

They might take a little longer to mature, but they’re well worth the wait.

In a greenhouse, they can grow tall and strong, shielded from harsh winds and snow.

Winter greenhouse gardening isn’t just about protection from the cold; it’s about extending the possibilities of what you can grow. At Greenhouse Emporium, we’ve seen countless gardeners transform their winter gardening experience with the right knowledge and tools.

So don’t let the snow deter you. With a greenhouse, winter can become your favorite gardening season.

When to Plant Winter Vegetables

The best time to plant winter vegetables is during the late summer to early fall. Why? This period allows your plants to establish strong roots before the harsh winter cold sets in.

By planting in this window, you’re setting up your veggies for a successful harvest during the winter months. At Greenhouse Emporium, we’ve seen countless gardeners reap bountiful harvests by following this simple guideline.

Remember, the aim is to enjoy fresh produce in winter, not to start the planting process then. So, mark your calendar and get those seeds in the ground when the time is right!

Caring for Vegetables in a Winter Greenhouse

Tending to vegetables in a winter greenhouse requires a unique approach. At Greenhouse Emporium, we’ve gathered insights over the years to help gardeners maximize their winter yields. Here’s our expert advice:


In our experience, plants in a winter greenhouse need less frequent watering. The reduced sunlight and cooler temperatures mean slower evaporation. However, it’s essential to monitor the soil moisture and ensure it doesn’t become too dry. We recommend using a moisture meter to strike the right balance.


Feeding your plants in the winter is crucial, but over-fertilizing can be detrimental. Our research indicates that a balanced, slow-release fertilizer works best during the colder months. This ensures your plants get the nutrients they need without overwhelming them.


Proper ventilation is vital to preventing mold and mildew. Even in winter, on sunny days, the temperature inside the greenhouse can spike. We recommend automated vent openers, available on our website, to maintain optimal airflow and temperature.


Harvesting at the right time ensures the best flavor and nutrient content. In our experience, some vegetables, like kale, even taste sweeter after a frost! Regularly check your plants and harvest when they’re at their peak.

Snow Removal

Heavy snow can block sunlight and strain your greenhouse structure. Our research indicates that using a soft broom to gently remove snow from the roof can prevent potential damage and ensure maximum light penetration. This is a crucial step in winterizing a greenhouse.
