When Should You Plant In A Mini Greenhouse?

Are you curious about when should you plant in a mini greenhouse? Whether it be spring, summer, or winter, you can. Well, there is a wide variety of homemade and professional designs when it comes to greenhouses. The generic term that people refer them to is the mini greenhouse.

In general, they are taking up less than 10 square feet of the floor space or ground. But they vary in terms of height – some are short, and some are tall.

Most gardeners utilize them to start seeding earlier than usual or to propagate plants indoors. This is mostly true for plants that like to grow in high humidity. The small greenhouse will protect them from various elements, including wind, snow, and rain.

Apart from that, it will also help you in extending your growing season, thereby increasing your yields. To achieve that, you should be able to learn how to use your mini greenhouse to the best of your advantage, and that includes knowing the right plants to grow in it as well as the right time to do it.


Mini Greenhouse Uses

Although mini greenhouses are not engineered for all types of gardening tasks, they are very handy on the things that they are good at. One of its most ideal uses is seed starting, especially if you utilize a single shelf.

Mini greenhouses are also very useful if you intend to clone plants present in your landscape. The plastic covers can trap the humidity; that is why you can easily and effectively perform graft or cutting.

However, this small structure needs significantly more care as compared to the standard greenhouse. That is since high levels of humidity, and the heat can rapidly build in there.

You have to monitor its temperature closely, especially when you build your mini greenhouse outdoors. Also, check its humidity levels regularly. Yes, humidity brings many benefits to most plants; however, it can result in the rotting of roots or even fungal diseases.

The plants that you can grow inside are not limited to those kinds of vegetables that are easy to start or full sun annuals. As long as you set the right microclimate within your mini greenhouse, you can use it to grow almost all kinds of plants you desire.

But of course, it is ideal to start with fruits, vegetables, and annuals. If you think that you can already control the condition better, you can try growing cacti, orchids, or carnivorous plants if you like.


Ideal Plants To Grow In Your Mini Greenhouse

There is a wide variety of plants, vegetables, and fruits that you can grow in your mini greenhouse. This includes tomatoes, peppers, eggplants, asparagus, lettuce, cucumbers, salads, squashes, sweet pop, and French cabbage.

But take note that some of which are best to be planted inside your small greenhouse in spring. Some are good during winter and some in summer. So when should you plant in a mini greenhouse? You should see to it that you will be growing appropriate plants based on the season.

For that reason, I decided to include the ideal plants to cultivate in this post, depending on the season for you to know when to grow in your mini greenhouse the plants you desire.


In Spring

During the spring, gardeners keep themselves busy growing young plants to soon transfer into their garden once they become ready. That is because spring is the perfect season to do so.

When the season begins, it is always good to cultivate plug plants such as Petunia, Begonia, and Busy Lizzies. After some time, you can transplant them, and eventually, they will bear beautiful flowers that will add life to your garden.


In Summer

When summer comes, you can utilize your mini greenhouse for seed starting. As mentioned above, it is a great structure for cloning the plants that are already growing in your garden, and during summer is the best time to do it.

The humidity levels during this season are best for grafts and cuttings. That is because the mini greenhouse can offer that appropriate warmth for tender summer plants like chilies, eggplants, and tomatoes.

This small yet incredible structure can also help your crop to grow larger and ripen more quickly. Aside from that, the mini greenhouse can also offer a perfect environment if you desire to propagate your plants.


In Winter

Some gardening specialists also claim that a mini greenhouse is an ideal solution for overwintering young plants. Not only that, but it is also a place to keep delicate plants such as fuchsias shield and geraniums.

You can even grow the bulbs that bloom only in summer and transplant them when spring comes. Much more, you can protect your alpines and your rockery plants against the rain if you place them inside your mini greenhouse. Doing so will prevent them from risks of rotting.



A mini greenhouse is a great structure for gardening hobbyists. When should you plant in a mini greenhouse? Whether the sun shines or the rain falls, it doesn’t matter. As long as you know how to control the climate inside.
