FAQs
Do I need another tree to get fruit?
No, the Opal plum is self-fertile, meaning it can produce fruit on its own without another tree.
When is the best time to plant this tree?
These trees can be planted year-round, provided the ground is not frozen or waterlogged, though autumn and spring are ideal.
How large will the tree grow?
As a compact variety, it is manageable for most gardens, though size depends on the rootstock and annual pruning.
Can I grow this in a large container?
Yes, it can be grown in a large, heavy pot, but it will require more frequent watering and annual feeding compared to a tree in the ground.
When should I prune the tree?
Pruning should be done in mid-summer to prevent the risk of silver leaf disease.
Troubleshooting
Tree is not producing fruit
Ensure the tree is receiving at least 6-8 hours of direct sunlight and that late spring frosts haven't damaged the blossoms.
Leaves are turning yellow
Check soil drainage; waterlogged roots can cause yellowing. Ensure you are not overwatering.
Fruit drop occurring prematurely
Regularly check moisture levels during hot, dry periods as drought stress is a common cause of fruit drop.

Setup, Compatibility & Care
Planting: Dig a hole twice the size of the 5-litre pot. Ensure the graft union is slightly above the soil level.
Sunlight: Plant in a spot that receives full sun to promote sugar development in the fruit.
Watering: Keep the soil consistently moist, especially during the first two years of establishment and during dry spells in July and August.
Feeding: Apply a balanced fruit tree fertilizer in early spring as new growth appears.
Mulching: Apply a layer of organic mulch around the base of the tree in spring to retain moisture and suppress weeds.
Pruning: Prune in mid-summer to avoid silver leaf disease, removing dead or crossing branches to maintain an open, goblet-shaped canopy.
