Replanting into soil previously used to grow similar tree species usually results in poor early tree growth.
The replant disease complex is caused by root lesion nematodes and several fungal genera, exacerbated by poor soil health.
Organically acceptable strategies to improve replant growth include nematode antagonistic cover crops, organic soil amendments, green manure cover crops, and Brassica seed meals.
Compost amendments show considerable promise for improving replant growth.
