Cultivars
Serr
Both English walnut and English oak are large trees with extensive root systems, competing for water and nutrients in the soil.
Larvae bore into the developing walnuts, causing damage and reducing nut quality. Symptoms include wormholes in the nuts and premature nut drop.
The larvae of this fly feed on the developing walnut husk, causing discoloration and damage to the nut. Symptoms include blackened or discolored husks.
Aphids suck sap from the leaves and young shoots, causing stunted growth and leaf distortion. Symptoms include curled or yellowing leaves and honeydew excretion.
Steps:
- Collect mature walnuts in autumn.
- Allow them to dry slightly.
- Plant the nuts directly in the ground in autumn or stratify them for spring planting.
- Grafting is a more reliable method for maintaining desired traits.
- Choose a compatible rootstock and scion.
- Perform the graft in late winter or early spring.
Neem oil

Kaolin clay
