How to grow

Good pest and disease resistance

Good pest and disease resistance

This variety can have issues with Slugs and Snails as well as Powdery Mildew. For Slugs and Snails, it is important to 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 leaves. It is also a good idea to spray your plant with water which has boiled some garlic in it for around 2 hours. For more serious slug and snail control you can also use specific nematodes that will find the pests and cause them to die. To prevent Powdery Mildew you should try to prevent crowded and humid conditions. Properly space plants apart and get rid of any weeds. Water at the soil and try to prevent soil splashing from the soil onto the leaves.MORE

Water often

Water often

Water several times a week during hot and dry periods to keep the ground evenly moist. During the non-summer months the rain should provide enough water for the plant, especially after it has established itself after its first year.

Full sun to partial shade

Full sun to partial shade

This variety will grow in areas of moderate sunlight, including around 4-6 hours of dappled sunlight in partial shade but also grows in full sun.

Fertile, well-drained soil

Fertile, well-drained soil

Mix in plenty of organic matter such as garden compost into the soil before planting. If your soil is particularly clay-heavy and easily becomes waterlogged, add some perlite or gravel into the soil to improve drainage.

Feed regularly

Feed regularly

Apply a mulch of well-rotted manure or compost in the autumn to protect the roots and to also give the soil added nutrients to promote healthy growth. ?v=1613300718

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.

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.
