How to Grow Fruit Trees in a Greenhouse

If you think of greenhouses as being reserved for exotic flowers and plants, it’s time to rethink your idea of these spaces. They can also be used to grow fruit trees. This is a great way to expand your home orchard and bring in new species that might not otherwise be able to thrive in your climate.

If you’re planning on growing plants in a greenhouse, make sure that they’re from a variety of climates that are suitable for your space.

Back in the day, greenhouses were the most common places where people grew citrus trees. Today, they can also grow avocados and even a few pomegranates.

If you’re not sure which tropical fruit to buy, you can always check the average height of the fruit on the list. Then, you can also look for dwarf varieties.

Can You Grow Fruit Trees in a Greenhouse?

Many gardeners are confused about the concept of growing fruit trees in a greenhouse. This is a relatively new concept, and it is not as hard as you might think. You will need a greenhouse that is large enough to hold the trees, a heat system, and a method for pollinating the trees.

If you’re looking for tropical fruits, a greenhouse can provide you with a wide variety of fruits and vegetables. So, can you grow fruit trees in a greenhouse?

Yes, you can grow fruit trees in a greenhouse. Greenhouse fruit tree growing can also help expand a home’s orchards. This process allows people to bring in species that would otherwise not be able to survive in their climate.

Although fruit tree cultivation is not as common as you might think, it is still possible to grow these plants inside a greenhouse.

The general environment of a greenhouse is very good for growing fruit trees. However, it is important to maintain a certain level of commitment to ensure that the tree bears fruit.

How to Grow Fruit Trees in a Greenhouse

The Size of the Greenhouse

Regardless of the type of fruit tree, you’re going to pick, a large greenhouse is going to be required.

You need to be able to reach the plants that are growing in your yard. In some cases, it may be necessary to have two trees for pollination.

If you have a budget, I would go as tall as possible. The minimum height should be around 9ft in the center. This will allow you to grow.

Picking Suitable Fruit Trees

Before you start planning your greenhouse, it’s important to think about the overall plan. Having the right plants will help you achieve the best possible climate.

If you want to grow tropical plants, make sure that you stick to those and don’t mix them with other plants.


Without pollination, fruit production doesn’t work properly. There are different types of trees that require different forms of pollination.

Cross-pollination is a process that involves attracting beneficial insects to your greenhouse. For fruit trees, you will need at least 2 trees.

Pots vs. in-ground

Most people will plant their fruit trees in pots so they can move them around. Doing so will reduce the tree’s fruit size. However, this doesn’t affect its overall size.

The biggest issue with growing trees in a greenhouse is that they can’t be easily changed. For instance, if you want to re-organize your beds after a few years, you might want to plant a different tree in its place.

Unfortunately, this method can also cause the tree’s roots to become too deep, which will prevent them from developing a complete weed protection system.

Growing Fruit Trees in Containers

The Choice of Pot

The container’s dimensions will be determined by the root system of the fruit tree. For instance, if the tree has a deep root system, then the container should be wider than it is tall.

Tap roots are the roots of fruit trees that look for their nutrients in the soil. They need a pot that’s a lot deeper than usual.

Fruit trees that develop deep root systems should be placed in a big container. Make sure that the space around the pot is wide and deep enough to support their growing roots.

It’s also important to choose a material that’s stronger and more durable than plastic. This will help prevent the pot from cracking.

If you are planning on planting a young fruit tree, then the container should be at least 16 inches wide. It should be re-potted after a couple of years. If you start with a smaller container, then you might not need to re-pot again for the first five years.

Soil And Compost

Use a high-quality soil that is free of pests and diseases. Also, choose a combination of leaf compost and topsoil to nourish the fruit tree. This combination will prevent the tree’s substrate from depleting its nutrients.


For organic fertilization, try using compost or earthworm humus. These are both very effective and can be made from your own kitchen waste.


One of the most important factors that a plant should consider when it comes to its care is irrigation. This is because it can help keep its soil moist and prevent it from getting dried out.

In open ground, the roots can fetch more water, but in pots, they don’t have this advantage. This causes the plants to get dehydrated.

When it comes to keeping your fruit trees healthy and growing, it’s important to install a drip irrigation system. This will prevent them from experiencing even temporary drought.

Before you start watering, make sure that the tree has its own water requirement. This will help determine how much water it needs.

When the soil is dry, water the plants when the top two inches of it are full. Then, let the water drain from the bottom of the container.

Repotting & Exchanging the Soil

You need to change the soil every two to three years to ensure that it provides the best nutrients for your plant. If your plant is still young, increase the pot’s diameter by a couple of inches.

After a while, it will become harder to re-pot due to the weight of the pot and the size of the pot. Instead, you can only change the surface by adding rich soil.

Every 4 to 5 years, you have to remove the tree’s pot and replace its soil. This is a tedious and time-consuming operation.

Trimming Roots

This operation is only performed on mature subjects. Take the root ball out of the pot and cut it with a pair of shears. Use a saw for larger roots.

Take out a small section of the root ball and remove up to four inches of roots. This will allow you to add more nutrients to the bottom of the pot.


With a greenhouse, you can control the environment of the fruit tree that you have. You can also regulate the temperature.

Fruits and vegetables that are grown in a pot are less hardy than those that are grown in the ground. This is because the soil no longer provides an adequate insulating layer.

If you’re looking to extend the growing season, consider investing in a gas or electric heater. An evaporative cooler can also help keep your plants cool during the summer months.

Growing Fruit Trees in Pots

In an unheated greenhouse, fruit trees can be grown in pots, boxes, or even in containers. The restriction of the roots prevents the trees from developing too early, and the glass catches the sun’s warmth, which helps protect the fruitlets from the harsh winter.

For this purpose, a pot-grown tree should be purchased, which should be filled with fruits and vegetables such as apples, cherries, plums, and gages. Set up the tree in a well-draining container and then cover it with a layer of compost.

The soil should be at least 2.5 cm below the rim of the pot to allow for proper drainage. To work the compost, start by working it around the roots, and then firm it down with a blunt-ended stick.

For organic compost, the following formula is commonly used by a nursery that has been producing pot trees for over a century. It consists of three parts fibrous loam, one part well-rotted manure, and a small amount of chalk.

During the winter, place the pots in a bed of ashes, which will prevent the entry of pests and diseases. The ashes will also help prevent the wood from turning brown. The cold weather will also help the tree develop properly.

The pots should be taken into an unheated greenhouse at the end of January. In order to conserve the sun’s heat, open the greenhouse at midday and shut it down early. During the first week or two, water will be required to allow the tree to start its syringing process. This process should continue until the fruit begins to produce.

By March, the water requirements of the pot should be increased, and this should be done daily. To avoid draughts, allow the tree to open its blossom when it’s fully open.

Well-rotted manure should be given to the pot tree when the fruit has all set. This will help prevent over-cropping and ensure that the fruit is thin. To prevent birds from entering the tree, the vents should be covered with nets.

The pot trees should be re-potted every year in October or November. After removing the tree, the soil is removed from the surface and the roots are shortened using the same formula.

A larger pot should only be provided once it’s absolutely necessary. New trees should also be purchased to use the first set of pots.

How to Take Care of Your Fruit Tree in Greenhouse

Aside from keeping the trees warm in winter, greenhouse fruit trees also require regular maintenance and monitoring of the environment. This includes making sure that the temperature doesn’t get too hot on sunny days.

For many fruit trees, such as citrus, you’ll need to consider fertilization and pollination. Having a greenhouse that’s designed to exclude pests can help, but it also has to be considered carefully to ensure that bees and other natural pollinators can thrive.

It’s time to start taking care of your fruit trees. Although they usually require little attention, they can require a lot of care to maintain their health.

Pruning and Trimming of Fruit Trees

After the leaves have fallen on the fruit trees, they go into a state of rest. This period allows you to carry out delicate tasks on the tree without damaging its structure.

You can prune fruit trees from the first year. They need to be kept well-developed and vigorous to maintain their appearance.

Pruning can help control the growth of certain fruit species, such as the fruit tree. It can also prevent the spread of fungi. To minimize the effects of the pruning, use clean tools and sharp ones.

After a few years, your trees will grow taller and taller. They should be kept trim so that they don’t damage the roof of your greenhouse.

Protection From Unsuitable Temperatures & Pests

While it’s possible to keep your fruit trees from threads, it’s also important to keep a consistent temperature to prevent pests and diseases.

Electric or gas heaters can help combat the effects of frost. In summer, you might also need to protect yourself from the sun.

Even if you don’t have a serious issue with pests or diseases, it’s still possible that you might purchase plants or tools that are infected.

You should also watch out for signs of pests in your greenhouse. These include fungi, aphids, and mites. Getting rid of these pests as quickly as possible will help limit their spread.

Choose a Rich Soil and Fertilizer

Like their counterparts planted in the ground, fruit trees require fertile soil to thrive. They also feed on nutrients and minerals to produce delicious fruit.

It’s best to use natural fertilizer products such as compost, guano, and earthworm humus. However, be careful not to over-fertilize.

Depending on the type of fruit tree and the soil, the amount of fertilizer that’s needed can vary. It’s also important to do a soil test before adding fertilizer.


In their natural environment, fruit and tropical plants would benefit from being partly enclosed under a canopy of tall trees that consistently stay wet and windy.

In the Mediterranean, for instance, it rains for a portion of the year instead of the whole year. This means that various plants and trees thrive in this environment.

Some of the most common sub-tropical plants include dwarf citrus trees, fruit trees, and flowers. Meyer lemons are also very popular in growing dome greenhouses.
