Small greenhouse tips: 5 ways to make the most of limited space

Tips to help you effectively use your small greenhouse

Having a greenhouse is useful, but it was also a luxury for many years. Now, thanks to smaller, portable greenhouses, almost any gardener can have a greenhouse of their own. There are even small greenhouse kits that can teach you how to make a small greenhouse on your own. However, since they’re smaller, you need to use the space more carefully. If you aren’t sure where to start, we can help.

There are plenty of ways you can use your greenhouse, but here are our top five tips for making the most of your smaller greenhouse!

Stagger your shelves

Adding extra shelves to your greenhouse is often the first step toward making the most of your small greenhouse, but where you put the shelves and what size shelves you use; can make all the difference.

Place the shelves that stick out the farthest on the bottom, then place shorter shelves over them. This gives taller plants room to grow without limiting the space you have available for other plants. You can also add multiple smaller shelves on the same level with space between them, providing breaks for hanging vines to trail or tall plants to grow.

Sketching your shelving layout before hanging can be helpful for this tip! It’s no fun to get halfway through hanging your shelves, only to realize you’ve made an easily avoidable mistake. Additionally, make sure to hang your shelves securely to avoid falling shelves and broken flower pots.

Depending on the material your greenhouse is made of, you may not be able to hang additional shelving. If that’s the case, look for smaller free-standing shelves, which you may be able to stack. Attach the shelves to each other for added stability.

Use hooks to hang potted plants

It’s easy to forget your greenhouse’s ceiling is an available space. There are plenty of vegetables and flowers that can grow in hanging pots, and secure hooks are easy to find at most hardware stores. You may need a ladder or step stool to reach the ceiling, and be sure the hooks attach securely before hanging your plants.

Vining plants are an obvious choice for this, and tomatoes are likely the first vegetable that comes to mind when thinking about a hanging garden. Morning glories, strawberries, and peppers are other good choices. However, smaller non-vining plants like lettuce, chives, and mint can also grow well in hanging baskets. You’ll just need to take the basket down to properly harvest them.

Rotate which plants are in your greenhouse

Plants have varying levels of cold tolerance, and you can use that to your advantage when moving plants into your greenhouse for the winter. You should move your most sensitive plants to the greenhouse first, along with any seeds or seedlings you’re starting. However, plants that are a bit more cold tolerant can stay outside for longer, giving you more time to arrange your plants and plan how you will use your space.

Plants moved into the greenhouse early may not stay there the entire time, either. You might find that some plants are better suited for the indoors, vegetables may be harvested, and unfortunately, some plants may die. In these cases, you can move those plants out of the greenhouse, allowing you to bring the ones left outside in before the cold becomes dangerous to them.

Don’t forget to use the floor room

Not every plant needs to be on a shelf. The floor of your greenhouse is an equally valid place to keep your plants. You should leave a bit of walking room, so you can reach your plants without tripping, but otherwise, you can put your plants wherever makes the most sense to you. If your greenhouse doesn’t have a solid floor, you can even plant your garden choices directly into the ground of your greenhouse.

If you’re concerned about the ground being too cold in the winter, spread a tarp, layer of newspaper, or even a bit of mulch underneath the plants. You can even use a small box or stand to lift them up just enough so they aren’t in contact with the ground. Want to know how to heat a small greenhouse? You can use compost!

Focus on smaller or faster-growing plants

When space is limited, you need to maximize the number of plants you can grow and harvest. An easy way to do this is to focus on growing plants you can harvest young (like kale, spinach, and lettuce). Additionally, if you grow smaller plants, you’ll be able to fit more in the greenhouse overall.

In principle, this may sound obvious. However, you can extend it beyond the plant itself. Plants that are small and grow quickly often have smaller root systems, which means they need smaller pots. Some plants that you harvest early can even be harvested as sprouts. Since the sprouts won’t be left to mature, you can plant more of them than you otherwise would in a single pot.

Whether you just want a place to keep your seeds during winter or plan on growing a full harvest of vegetables, these tips will help you achieve your gardening goals. Not every tip will work for every gardener, so be sure to test them out and see what fits your gardening style the best! Remember that there’s no harm in trying out a new idea, and if you absolutely can’t make it work, you can always get a second small greenhouse.

5 outdoor lighting tips we learned from experience so you didn’t have to
Hanging outdoor lights

One of the most exciting parts about setting up an outdoor space is designing the lighting in a way that makes it not only beautiful to look at but enjoyable to spend time in. The types of lights and where you place them will depend on what your space looks like. Even in an urban apartment or home, you can accentuate balconies and patios with lights that make summer evenings feel a bit more magical — but how do you know what to choose? It’s natural to make mistakes the first time around, like buying bulbs that are too large or a lamp with a cord when you don’t have an outlet. Luckily, we’ve got a few outdoor lighting tips up our sleeve to help you forgo some of those initial hiccups.

Different types of lights you can use
First thing’s first: it’s important to assess your space and consider the different types of lighting you can use for it. If you’ve got a deck with stairs, you can utilize things like lights placed under the steps to illuminate them or rail lights to keep the night extra safe. These lights are usually subtle, so you don’t have to worry about them overpowering the area.

Houseplants under grow lights

Just like growing houseplants indoors, growing plants in a greenhouse requires specific care and a suitable environment. Even though the greenhouse will have some light from the sun coming in, the glass panes are often filtered in some kind of way to prevent your plant’s leaves from scorching. Enter grow lights. They’re used most commonly in darker spaces or during colder months; however, they're greatly beneficial to your greenhouse plants and help ensure that the plants are getting the light they need to thrive.

Can you have an indoor greenhouse?
Absolutely! Indoor greenhouses are revered for how sustainable and inexpensive they can be. An indoor greenhouse with lights can be installed anywhere in the home where you have the space, and it’s a perfect place to grow things like fruits, herbs, and veggies indoors. If you’re only planning to grow a couple herbs, you can get something as small as a tabletop greenhouse! It will fit a few plants, won’t take up too much space, and will add to the aesthetic of a room while letting you grow plants in a unique way.
