Over the years, there has been a significant increase in the number of people who are taking an interest in allotment growing. Whether your allotment is small or large, having a defined space for growing plants offers a therapeutic routine that many people value as a hobby.
However, if you’re a long-time grower, you already know the amount of care it takes to ensure your allotment continues to thrive. For instance, your plants’ growth is heavily influenced by moisture levels and sunlight.

On some days, the soil dries out faster than you expect, and on other days, you wish you had a more reliable watering system to take care of your plants.
Manual watering does the job, but it starts becoming a time-consuming task as your plot expands. If you step away for a short trip or face a long dry spell, keeping up with your plants’ watering needs becomes difficult.
An irrigation system makes that job easier by consistently delivering automatic, precise watering. It helps you maintain a steady flow for your plants and protect your stored water, giving you more time to focus on the parts of gardening that you enjoy most.
In this article, we’ll cover 6 irrigation system providers in the UK that can help you keep your allotment healthy with automated and accurate watering through every season.

Customer Review
Here’s what a customer had to say about Harvst’s irrigation system on Trustpilot:
“Great product that has made my Greenhouse a lot easier to use. Much more powerful then all the other Solar irrigation systems that are out there. Having the wrong system can kill all the plants you have. This one is also connected to the internet, so you can see if it has watered, the temperature of the site and is intelligent to water more if the temperature hits certain points you can program in. Much more professional and cleaner to set up with a main water system around the greenhouse that then you can connect your dripper feeds, rather than having tiny hoses around, where if one fails, your whole system would not work. With this, you do not have this problem.
I must not forget to add, their support is fantastic, fast and local!”
