How to grow
How to grow
Excellent pest and disease resistance
Generally free of pests and diseases, but young plants may be vulnerable to slugs and snails. Keep the area around the plant debris free and as dry as possible, especially at night as slugs and snails love damp conditions. You can use barriers such as egg shells or copper wire to surround the plant to prevent slugs and snails reaching the leavesMORE
Keep well watered
Needs a permanently wet soil - do not allow soil to dry out.
Full sun to partial shade
Position where the plants will receive at least 4-6 hours of sunlight daily in spring/summer.
Rich medium to wet soil
Any permanently moist or waterlogged soil. Tolerates poor drainage.
Feeding not required
No need to feed - this plant gets all the nutrients it needs from the soil. ?v=1613300967

Best plants you will ever get online
I have ordered plants from them twice this year. They arrived well packaged, on time and looked strong and healthy. I feel the staff from Roots plants deal with their plants and customers with passion and care. I can’t wait to order again, price is good as well.
Highly recommended all round
Delivered quickly, perfectly packaged and the tree was in excellent condition. Really healthy and taken to the garden with no problems. Can't recommend highly enough. 5 stars isn't enough!
Satisfied customer
Unlike other online sellers, this company are well ahead in the quality stakes. My plant arrived promptly as per their promise and the plant was much more established and healthy than I had expected. It’s the second time I have ordered from them and I have faith in their promise. Excellent service.
A really good quality tree
A really good quality tree, delivered on time and very well packaged. But the emailed planting advice and supporting information was what really impressed me. Thoroughly recommended.
Exceptional quality
The quality of the plants was exceptional, unlike ones I have had before from local garden centres. Thank you so much. I will definitely be using you again.
Marvellous!
Marvellous service, great plants and fast delivery. Very useful information on how to care for the plants I bought. Easy to use website that makes it far too easy to overindulge in fabulous plants 😂🌱
