Q:Does Height Really Matter?

A: Not As Much As You Might Think...
One stand out specification that customers often use to judge the value of a tree is the height. So should height directly correlate with the price of a tree? No, not necessarily.
To an extent the height of a tree can give you a good indication of its maturity but you must not forget: To grow a productive, well shaped, healthy tree you must prune it back regularly, especially when young.
Our trees often grow up to 2m in the fields before we prune them back and package them ready to send out. This pruning encourages the tree to grow more, stronger branches and ensures there is a good balance between the root size and top growth. This ensures that your tree puts energy into establishing a healthy root base instead of supporting top growth, providing a better foundation for your tree in the future.
So, in summary: Dont let the extra 10/20cm you may find elsewhere sway you. You are likely to be paying extra for the delivery costs and, if you want a healthy tree in the long run, youre going to have to chop it off anyway!

Caring and Maintenance

Water young trees regularly until roots are well established. Trim annually from mid to late summer. Apply some fertilizer in spring in order to promote healthy growth. Optionally, mulch in spring. Check tree ties regularly and loosen any if necessary to avoid rubbing of the stems.


  • Planting Distance: 8m

Suited to almost all well-drained and moderately fertile soils in either an exposed or sheltered location with either full sun or partial shade.
Before planting your tree, clean up all wandering weeds and keep a clean ring around the tree base. Water well during the first year until well established.

Autumn is the best season for planting trees, as the soil moisture and heat allow easier and faster root establishment and regeneration of damaged root systems.

This is an example of our polypot - note the fruit/ornamental trees we stock will vary in appearance according to species and season.

Bare Root

Bare root trees are a great alternative to container grown versions during the winter.

Whilst trees are dormant, they are easier to transport and plant and are a little less delicate than in the summer.

Planting in late autumn/ winter provides the tree with the opportunity to establish a strong root system so that it is ready to burst into life come spring.

We wrap the roots of all our trees with a special bag and compost to help them retain moisture and ensure they arrive on your doorstep as healthy as possible.

"I was a little wary of ordering a tree online since you can't choose the particular one that you prefer, but the tree that I was sent is lovely - a very good specimen and a well balanced shape. I would be happy to order from Primrose again."
