Put into consideration the changes in the weather every year. Therefore, expect a lot of adjustments to make sure that the environment inside your greenhouse is ideal for plants to flourish.

The most challenging part for every gardener would be during the winter season. During this time, the heat inside your greenhouse may decrease, which weakens your plants causing them to be sickly.

Those who do not experience the four seasons still face challenges as they try to grow plants yearround. During rainy days, the temperature outside of the greenhouse also decreases. A flood can sometimes occur when a storm hits.

Growing Vegetable YearRound In A Greenhouse

Without further ado, here is a list of the ways on how to grow vegetables year round in a greenhouse:


#1 Get to know your vegetables

Every vegetable varies in shape, size, color, and taste. The same goes for the environment where it usually grows. Knowing what kind of condition your vegetable prefer will help you imitate it inside a greenhouse.

You’d want to know what season your vegetable grows abundantly, so here are the following plants best for each season:



  • brussels sprouts
  • winter squash
  • cabbage
  • potatoes
  • carrots



  • radishes
  • spinach
  • asparagus
  • broccoli



  • bell peppers
  • kale
  • mushrooms
  • onions



  • tomatoes
  • corn
  • zucchini
  • cucumbers

In contrast, some plants can strive in any season.

What is important is that you know which season your chosen vegetable sprouts. When picking what type of vegetables, you will plant inside your greenhouse, ensure that they all thrive during the same season.

To make it easier for you to adjust the humidity, temperature, and other factors to provide a desirable place for the veggies. However, as the environment as where you are in, we suggest you tend to plants coming from the same. It will minimize your work as you almost have everything your vegetable needs.


#2 Choosing a container and the kind of soil

Now that you’ve chosen your vegetables to grow, it’s time to use your selected container and soil. The best container must drain excess water completely. It must also have enough space for your plant to grow freely. The type of container will depend on your vegetable.

We suggest the first plant the vegetable in a container, even if you’re planning it directly to the soil. Potting is best for starters, as it does not require additional building. Choosing a pot relies on your taste; buying pot trays would help move pots effectively.

Adding to this, you’d want to use fertile soil with a mix of compost. It will not only improve your soil’s quality but will also provide heat for the plants.


#3 Control the greenhouse condition

You should control the amount of light, temperature, humidity, and water in your greenhouse.


Amount of light

We learned from our biology class that plants need sunlight to undergo photosynthesis. As much as humans need sun for warmth and other purposes, plants utilize sunlight to make their food.

To make use of the natural light, ensure that the greenhouse is not in a shady area. Place the plant where it can directly receive the sunlight. However, it’s not every day that you can see the sun.

Therefore, you’d rely on LED lights to temporarily replace natural light. Especially in winter, installing a lighting system will help your plants grow without sunlight. There are also lights for warmth available.


Ideal temperature

You’d want to measure the temperature outside of your greenhouse as it also affects the condition inside. Using a thermometer will help you track any temperature changes, allowing you to do something to maintain it.

Avoiding the fluctuating in temperature will help your plants to stay healthy by not disrupting it.

To maintain the temperature in colder seasons, some gardeners would set up a heating system inside their greenhouse. However, it can be quiet pricey.

Therefore, we suggest you stick with insulation to save you time and money. Adding insulation will involve placing horticultural bubble wraps on the walls of your greenhouse. But if the weather outside is just too cold, then you’d rely on the heating system as well.

Additionally, do not forget about ventilating the grow room to let in fresh air to reduce the moisture inside. Growing vegetables seasonally do not require you much heat for winter, as long as the condition suits the season outside your greenhouse.



The amount of humidity mostly depends on the type of vegetable and climate. Once again, always consider your place’s environment and choose what type of vegetable you think can strive.

You can make use of misting, the cheapest way to provide humidity for your plants. As seasons change, your plants will require less amount of moisture.

Therefore, spend more time inside your greenhouse and observe if it needs more humidity or not. You can tell it by feeling the moisture of the vegetables; try it!



Lastly, make sure that the vegetables receive enough water every season. They may need more water during summer and less in winter, so do adjust when needed.

Once again, please get to know your plants as their needs vary from each other. If you manually water your plants, do check if it needs watering by feeling the soil. If it is damp, then skip to the other pot to water.

You’ll notice during winter that your vegetables need less watering. Moreover, the automatic water system is an available option for you if you want to save time on watering each of your veggies.



Keep in mind the environment where your greens are from and its type to provide them the ideal condition inside your greenhouse. Hopefully, this article about how to grow vegetables year round in a greenhouse gave you more insights into your greenhouse gardening plans. Thank you for your time!
