I wonder if it is possible to Grow Soursop in the UK and Ireland?

Updated: Mar 21


Growing your own food is one of those simple joys in life—something that connects us back to the earth, back to traditions, and back to the sense of accomplishment that comes from nurturing a plant from seed to harvest. If you’ve ever tasted soursop, that tropical fruit with its creamy texture and sweet-sour flavour, you might be wondering if you can bring a little taste of the tropics into your own backyard, even here in the UK. But can soursop really grow in a climate as temperate as ours? Let’s explore that together.

 

Understanding the Soursop

 

Soursop, also known as Graviola or Annona muricata, is a plant native to the warm, humid climates of the Caribbean, Central America, and parts of Southeast Asia. It’s a tree that, when given the right conditions, can produce large, heart-shaped fruits with a spiky exterior and a soft, white flesh inside. The fruit is prized not just for its taste but also for its potential health benefits, which have been celebrated in traditional medicine for centuries.

 

But here’s the thing—soursop is a tropical plant through and through. It thrives in environments where temperatures consistently stay warm, humidity is high, and the sun is hot, hot, HOT!. So, the question becomes: can we create an environment like that here in the UK?

 

The UK Climate: Friend or Foe?

 

The UK is known for many things: rolling green hills, historic castles, and, of course, its somewhat unpredictable weather. Our climate is what’s called temperate, meaning we experience relatively mild temperatures year-round, but with a fair share of rain, chilly winters, and only brief bursts of warm, sunny weather.

 

Now, if you’ve been following along, you’ll know that these conditions aren’t exactly what soursop dreams are made of. Soursop trees need warmth—typically, they thrive in temperatures between 25°C and 30°C. Anything below 15°C, and you’re running the risk of damaging the plant, particularly its leaves and fruit. And frost? Well, that’s pretty much a death sentence for soursop.

 

So can Soursop grow in the UK and Ireland?

 

Despite these challenges, the story doesn’t end here. Where there’s a will, there’s a way, and with a little creativity and care, growing soursop in the UK isn’t entirely out of reach. Let’s talk about how one can actually turn this dream of growing soursop in the UK and Ireland into as reality:

 

1. Greenhouse Cultivation: Creating a Tropical Oasis...Indoors

 

One of the most practical ways to grow soursop in the UK and Ireland is by using a greenhouse. A well-maintained greenhouse can replicate the warm, humid conditions soursop needs to thrive. By controlling the temperature, humidity, and even light, you can create a little slice of the tropics right in your garden.


The top five benefits of using a greenhouse are as follows:

  1. Energy efficiency. Takes advantage of the environmental conditions, such as optimizing the heat inside the greenhouse.

  2. Control of microclimate. One of the main advantages of a greenhouse is to control and establish the optimal environment for cultivation. You can adjust the temperature, humidity, lighting, etc.

  3. Protection against diseases, pests and other vermin. Another advantage of a greenhouse is that it is very difficult to enter as it is a closed space.

  4. Optimum ventilation. You can ventilate the greenhouse quickly, thanks to their zenithal or side windows.

  5. Creating an optimum seal indoors against rain and air.

 

Of course, this isn’t without its challenges. Maintaining a consistent indoor temperature—especially during the coldest months—requires a reliable heating system.

 

 

2. Indoor Growing: Bringing the Tropics Inside

 

Another option, particularly if you don’t have space for a greenhouse, is to grow soursop indoors. This could be done in a large pot by a sunny window, or with the help of grow lights to supplement the natural light. The key here is to maintain warmth and humidity while ensuring that the plant has enough room to grow—soursop trees can get quite large, so you’ll need to manage their size with careful pruning.

 

Indoor growing does present some unique challenges, like ensuring proper pollination (which may require manual intervention) and dealing with potential pests. But with patience and attention, it’s possible to grow a healthy soursop tree indoors.

 

Learning from Experience

 

There are a few success stories from gardeners in the UK and other non-tropical regions who’ve managed to grow soursop with varying degrees of success. These stories often share a common theme: persistence, creativity, and a willingness to experiment.

 

One gardener I spoke with managed to grow a small soursop tree in his greenhouse in Kent. He said, “It’s a labour of love, really. I keep the temperature up, mist the leaves regularly, and I’ve got a heater on standby for those really cold nights. It’s not easy, but when you see that first fruit forming, it’s all worth it.”

 

Practical Tips for Growing Soursop in the UK and Ireland

 

If you’re ready to give it a go, here are a few practical tips to get you started:

 

1. Choose the Right Variety: Some soursop varieties may be more adaptable to cooler climates, so it’s worth researching which type of soursop might be best suited for your situation.

 

2. Prepare the Growing Environment: Whether you’re growing indoors or in a greenhouse, make sure your plant has rich, well-draining soil, and consider using a soil heater to keep the roots warm. For a project of this nature, preparation is key.

 

3. Be Patient and Observant: Growing soursop in the UK and Ireland will require close attention to the plant’s needs, especially in adjusting to the changing seasons. Regularly monitor the temperature, humidity, and overall health of the plant, and be ready to make adjustments as needed.
