Planting Advice for Euonymus hamiltonianus 'Koi Boy'

Our pot grown Koi Boy Spindle trees can be planted at any time of year. Remove weeds and grass near the planting site, then dig a square hole as deep as the root mass and twice as wide. We recommend sprinkling root grow in the hole to aid establishment, especially if you have poor soil.

Remove the pot, gently loosen the roots and place into the planting hole. Mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank soil up around the collar of the tree.

For single stem forms of Euonymus, use a staking kit with the stake inserted into the ground at an angle to avoid penetrating the rootmass. Water around the base.

Aftercare Advice for Euonymus hamiltonianus 'Koi Boy'

If you’re planting Spindle trees in spring, summer or dry weather, water well and regularly for the first few months. Make sure to keep an eye on young plants and increase watering if there are periods of hot and dry weather. If you’re planting in autumn, you may only need to water a little.

Keep the area around Euonymus free of competing weeds and grass for the first couple of growing seasons.

Pruning Advice for Euonymus hamiltonianus 'Koi Boy'

Spindle trees do not require regular pruning. If you wish to tidy Euonymus up, do this during the dormant season. Focus on removing any damaged, diseased or overcrowded branches. If you require a clear trunk, remove any side shoots to help raise the crown.
