Growing a variety of plants in your greenhouse can allow you to produce more food while still limiting your garden to a single area. A 20 foot dome is big enough to provide gardeners with plenty of room if they would like to grow more than one type of crop. Beds, containers, shelves, and other growing methods can all be utilized with proper planning.

Grow Plants That Won’t Overcrowd Your Space

Use the Floor Space for Larger Plants

Large plants will typically require more space than smaller crops. You may want to utilize garden beds in order to provide larger plants with their own growing area.

A 20 Foot Dome Greenhouse provides enough floor space that you can separate larger plants from smaller ones. You should still leave adequate room between beds or rows for accessing your plants in order to water, prune, and harvest.

Pay attention to how large each plant will grow before you choose its location. Planning ahead can reduce your chances of overcrowding later on.

Grow Different Vegetables Together

When you have more space in your greenhouse you can grow multiple types of vegetables simultaneously. One area could be used for growing leafy greens while another area could be used for larger vegetables.

Sections of a 20 Foot Geodesic Dome Greenhouse can be used as individual growing spaces. You may even want to group vegetables together that have similar growing requirements. This can make caring for your plants easier.

Try not to mix plants that have very different space requirements. Providing each plant with enough space can help to keep your garden more organized.

Add Containers for Flexibility

Containers can provide you with more options when it comes to organizing your greenhouse. There will be occasions when you need to move plants around in order to change your setup.

A 20 Foot Greenhouse Dome can hold both containers as well as garden beds. Containers can be used for small plants while larger plants can take up permanent residence in garden beds.

You can even use containers to move plants outdoors at a later time if you choose.

Make Use of Vertical Space

Not every plant needs to be grown on the ground. Adding shelves or other vertical growing platforms can give you more growing space above the floor.

Plants such as herbs, seedlings, and small plants can be placed on shelves. This gives you more room to grow while ensuring that your greenhouse will be easy to move through.

Be sure to place shelves in an area where you can reach the plants without difficulty. Shelves should not be blocking walkways or your ability to care for the larger plants.

Create Separate Growing Zones

Divide your greenhouse into different growing zones. This will allow you to separate plants based on size and how you plan to access them.

A 20 Foot Dome Greenhouse Kit allows you to design a layout that will work for your planting intentions. You can create different growing zones based on plant size, water requirements, and more.

It can even be helpful to leave open space if your plants will need room to grow. Many plants will require more space once they reach maturity.

Grow Herbs and Smaller Plants

Growing herbs can help you maximize space because they often do not require as much room as larger plants. You can grow herbs in containers, beds, or shelves depending on your setup.

You can even dedicate a section of your 20 Ft Dome Greenhouse to growing herbs. Herbs do not typically require as much space as larger vegetables.

Basil, parsley, cilantro, mint, and many other herbs can be grown in your greenhouse. Grouping herbs together can make it easier to harvest and water the plants.

Use the Greenhouse for Seedlings

Seedlings are another great way to maximize the space in your greenhouse. You can keep trays and small containers on shelves or tables while larger plants grow on the floor.

Once seedlings have matured you can transplant them to larger containers or into garden beds. Allowing plants to start in your greenhouse can free up space for them later on.

Creating a dedicated area for seed starting can also help you to keep young plants organized.

Leave Enough Room for Walkways

Just because you have more growing space doesn’t mean you should try to fill every inch of your greenhouse with plants. Ensure you leave enough room to access your plants and supplies.

Walkways should make it easy to water, prune, harvest, and check your plants for pests. They also allow you to move tools and supplies around without knocking over plants.

Plan your layout in a way that allows you to reach every plant once it has grown to full size.

Group Plants by Their Needs

Plants can have varying requirements. Some plants may require more sunlight than others. Different plants may also have different watering needs.

Group plants with similar needs together to make your life easier. Plants that need frequent watering can be grouped while plants that don’t need water as often can be grouped together elsewhere.

Organizing your plants by their needs can help you develop a regular maintenance routine while maximizing your growing space.

Plan for Seasonal Changes

Your greenhouse does not need to have the same setup throughout the year. Certain crops can be planted during different seasons to take full advantage of your growing areas.

Using containers and shelves that can be moved can make changing your setup easier. You may want to start seedlings in one area of the greenhouse while later using the same area for herbs or vegetables.

Always try to plan ahead for how you can continue making use of your greenhouse.

Think About Plant Size

When deciding how many plants to grow you should think about what you plan to grow. Ten small herb plants will take up much less room than ten tomato or pepper plants.

Look at the expected mature size of each plant before putting it in your greenhouse. Allow larger plants enough room to grow so they won’t end up crowding nearby plants.

By planning ahead you can create a realistic growing plan rather than trying to fit as many plants into your greenhouse as possible.

Keep Gardening Supplies Organized

You may also need room to store gardening supplies. Pots, soil, trays, hand tools, and watering cans should be kept stored away instead of left out in the growing areas.

Using shelves or other storage containers can help you maximize space and stay organized. Store supplies you use often within easy reach.

Choosing to grow in a 20 foot dome will open up a wide variety of growing options. Vegetables, herbs, seedlings, and much more can all be grown in a greenhouse of this size. How much you can grow at once will vary based on your crop choices and the mature size of each plant.

Using beds, containers, shelves, and other organizing methods can help you maximize space in your greenhouse. By leaving room for walkways and proper spacing your plants will thrive.
