Can You Grow Blackberries In A Greenhouse
Because blackberries are a little more demanding in their care as compared to other fruits, growing them in a greenhouse can be a very good option. Blackberries like plenty of moisture in the air and soil, so it is important that you take extra care of your plants if you choose to grow them outdoors. The advantage of growing blackberries indoors is that you will be able to have control over their environment.
Blackberries are one of the easiest fruits to grow in a greenhouse, as they prefer to grow in damp and dark places.
Blackberries are one of the easiest fruits to grow in a greenhouse, as they prefer to grow in damp and dark places. They like a soil pH of 6.0-6.5, which is easy to achieve with a little lime or wood ash.
You can start growing blackberries from seed or by planting rooted cuttings (also known as “strigs”). Either way, you need to keep them moist until they’re established—watering once a week is usually enough—but after that they’ll do just fine with rainfall alone.
It is important to research the variety of blackberry you want to grow and to know that some varieties are better suited for indoor growing than others.
It is important to research the variety of blackberry you want to grow and to know that some varieties are better suited for indoor growing than others. For example, if you have a greenhouse with high temperatures and humidity levels during the summer months, most varieties of blackberries will do well there. However, if your greenhouse has low temperatures in winter months (below 35°F), only certain varieties will survive. These include:
- Mary’s Seedling
- Shady Lady
- Black Satin
If you can get a hold of a primocane variety, these varieties are generally smaller, more compact bushes, with shorter canes that are easier to train and maintain.

Growing blackberries in a greenhouse will protect your crop from birds, and take advantage of the warmth this microclimate can provide during the winter months when blackberries are dormant.
Growing blackberries in a greenhouse will protect your crop from birds, and take advantage of the warmth this microclimate can provide during the winter months when blackberries are dormant. Greenhouses are also cooler than outside conditions in summer, which helps to prevent overheating of your plants.
Greenhouses also provide better light than most areas outside, making it easier to achieve good growth for your plants. Additionally, greenhouses tend to be easier for gardeners to maintain and protect from pests or diseases that could otherwise destroy their harvest.
When planting, prepare 4-inch pots with a 50 percent peat-based soil mix.
When planting, prepare 4-inch pots with a 50 percent peat-based soil mix. You can buy this at your local garden center or make your own by mixing equal parts of potting soil and compost. The compost should be from a good source to ensure that it has plenty of natural nutrients for the plants to use.
The plants will need something to anchor them in place as well as enough space for their roots to grow and develop properly. To achieve this, you’ll need to fill each pot about halfway with the soil mixture before setting it aside while you work on the next one. Once all four containers are ready, plant three blackberries in each container; if you end up having too many berries growing next year then they will take care of themselves!
Water in well and leave out at room temperature until roots appear (around three weeks).
When the roots have appeared, you can transplant your blackberries. Do so immediately after they have rooted, as root growth slows once they are out of the water.
You need to make sure that the soil is well drained and that your greenhouse has good ventilation, especially at night when temperatures dip below freezing.
Plant into well dug ground with plenty of compost at least 2.5 meters apart.
Planting distance depends on a number of factors, including the type of blackberry you’re planting and the soil type. In general, the recommended distance is 2.5 meters between plants. This can vary depending on soil type: sandy soils will require more spacing because they drain quickly and don’t retain moisture well; clay soils will have greater drainage but may not support deep root growth.
Planting depth also has an impact on plant health—the deeper you plant your blackberries (up to 35 centimeters), the better established they’ll be when it comes time for harvest!
They need moisture but good drainage, so add plenty of grit if your soil is heavy.

- Blackberries like a soil that is slightly acidic, with pH between 6 and 7.5 (pH 7 is neutral). To test the acidity of your blackberry bed, collect a small sample in an airtight container and take it to your local garden center or nursery for testing. If the results indicate that you should adjust the pH, add lime or wood ashes according to package directions until it reaches 6 to 7.5.
- Blackberries thrive on organic matter such as compost or aged manure; one application per year should be sufficient for most gardens.
If you want to grow trailing varieties outdoors, plant them along 5ft wire arches or a strong trellis.
If you want to grow trailing varieties outdoors, plant them along 5ft wire arches or a strong trellis. The arch or trellis should be at least 5ft high so that the canes don’t touch the ground and rot from too much moisture.
Water regularly until established then less often unless it’s very dry.
Once established in your greenhouse, blackberries will require little or no additional water. The first year or two you should ensure that the plants are getting enough water so they don’t dry out and die, but after that you can cut back on watering significantly.
To determine whether or not your blackberry plant needs watering: Check if the soil feels dry 1-2 inches below the surface of the potting mix. If it is still moist at this level, then no additional watering is needed at this time. If it has dried out completely and/or seems like it will be difficult to get enough moisture into them to survive until next spring without frequent irrigation, then there are two options for you to consider:
- Watering once per week with a gentle stream from a lukewarm shower head (this method may not be feasible if you live in an apartment or have very limited access to running hot water). This method should only be used as necessary since overwatering can cause root rot problems and even death in some cases; however if done properly this method can help maintain healthy plants while reducing ongoing maintenance requirements considerably over time compared to other methods such
- Transplanting each plant into its own 5 gallon bucket filled with moistened potting mix before placing them back under full sun conditions outside where they’ll receive plenty of natural rainfall which will keep them adequately hydrated throughout summer months when temperatures begin reaching upwards towards 100° F.”
Don’t tie them in too tightly as the stems need some room to swell as the fruit develops.

- The fruit develops on new growth, so you don’t want to cut off too many of your blackberry canes at once or they won’t have enough energy to produce fruit next year.
Blackberries can be grown year round inside a greenhouse
Blackberries can be grown year round inside a greenhouse, but not outside. In fact, it’s best to grow them in pots so that you can bring them indoors and place them in the sun during winter months.
One of the most challenging aspects of growing blackberries in a greenhouse is keeping them tidy and trained. They will always need pruning and training to keep their fruit well within reach, so it’s worth thinking hard about how you will do this before you commit to planting your berries. If you want trailing berries that can be picked from the base up, then think about using 5ft wire arches or a strong trellis along which your berries can run. Bush varieties will need less training but still benefit from a bit of structure around which they can grow.
