- Amending the Soil: Add organic matter, such as compost or manure, to improve drainage and fertility.
- Testing the Soil: Conduct a soil test to determine the pH and nutrient levels.

Watering and Fertilizing
- Watering: Water thornless blackberries regularly, especially during hot, dry weather.
- Fertilizing: Fertilize the bushes in early spring with a balanced fertilizer.
Pest and Disease Control
Thornless blackberries are susceptible to pests and diseases, including aphids, mites, and anthracnose.
