5 greenhouse trends that will be everywhere in 2025
As our greenhouses wind down for winter, now is the perfect time to plan for the year ahead.
From rainwater harvesting to natural pest control, the experts at Hartley Botanic have revealed the top greenhouse trends set to shape 2025.
Garden greenhouses have become more popular over the years, allowing gardeners to extend the growing season, sow plants earlier, and store supplies during bad weather.
If you're the proud owner of one, or are simply keen to know what's trending, take a look at the top greenhouse predictions for 2025:
1. Greenhouse partitions
Greenhouse partitions are on the rise for 2025. With a partition, you can create separate growing environments for your plants within the same structure.
"Partitions in greenhouses are becoming increasingly popular as gardeners look for more precise control over their growing environment and formally divide structures for additional lifestyle uses," says the team at Hartley Botanic.
"By dividing greenhouses into distinct zones, partitions allow for tailored microclimates that cater to the specific needs of different plants optimising conditions such as temperature, humidity, and light exposure.
"This not only improves plant health, it also enhances resource efficiency, allowing for more specific heating, ventilation, and watering. Additionally, as a physical barrier, partitions can reduce the spread of pests and diseases and the need for environmentally-friendly controls."
2. Rainwater harvesting
Rainwater harvesting (RWH) is big news in gardening. According to Hartley Botanic, the demand for water butts is growing as homeowners look for ways to save money, reduce their monthly water bills, and help the planet.
"Rainwater may swing from being sporadic to torrential as a result of climate change, it is also better for plants, as it often has a lower pH. The minerals that are sometimes found in mains water, especially in hard water areas can raise the pH of your root zone, which can affect nutrient availability," says the team.
"Rainwater is vital for the healthy growth of ericaceous plants such as azaleas, camellias and rhododendrons."

3. Natural pest control
Biological pest control uses natural enemies rather than harmful chemicals to control pests. This works by inviting beneficial insects to your greenhouse to prey on common pests, such as greenflies.
Hartley Botanic predicts this will be common practice for greenhouse owners in 2025. But how does it work?
"The predatory wasp Encarsia formosa can be used to combat whitefly. Meanwhile, a rove beetle named Atheta coriaria can help get rid of red spider mites. You can also control mealybug, with the ladybird Cryptolaemus montrouzieri." Simply attract them with their favourite flowers and let them get to work.
Don't forget to check plants regularly for signs of an infestation, as it is easier to control smaller occurrences.

4. Successional growing (year-long harvesting)
Successional growing, also known as successional planting, is an easy way to keep your garden productive so there is always something to harvest. And greenhouses are the perfect places for this to take place.
"Greenhouses provide a controlled environment that can extend the growing season and protect plants from undesirable weather. For those who grow their own food, this means edible plants year-round, it also means enjoying the benefits of bulbs flowering early.
"'Successional sowing' allows for growing and harvesting 'cut and come again' edibles at all stages of growth. This can range from microgreen seedlings to juvenile and mature plants and will result in an interesting array of eating textures — from soft to crisp."
5. Shelving and staging
Shelving is essential for efficient growing in any greenhouse. For 2025, Hartley Botanic expects shelving and staging to take root, as people organise and declutter their greenhouses.
"There are many accessories that can help you make the best use of your greenhouse and using a mix of shelving and staging is highly effective," says the team.
"As greenhouses increasingly evolve into multi-use growing and lifestyle spaces, attractive ways to organise them are becoming more popular boosting the interest in staging and shelving."
