Blackberries produce best in full sun, but they can tolerate partial shade. However, plants do not grow or produce well in heavy shade.

Blackberries are sensitive to wet soils. Therefore, drainage is an important factor to consider when you're selecting a site. If blackberry plants are in waterlogged soils for more than a few days at a time, they normally die a slow death from lack of aeration (oxygen) or from subsequent attack by root diseases. Plants do best in a well-drained, fertile, loam soil with moderate water holding capacity. Avoid heavy clay or sandy soils.

Preparing the soil. You should be able to keep your blackberry planting productive for 15 to 20 years, so choose and prepare a site carefully before you establish the planting.

Almost any soil type is suitable for blackberries as long as the drainage is good.

Blackberry plants require about 1 inch of water per week from mid-June through harvest. When rainfall doesn't provide this amount, you should irrigate. Extremely warm and windy conditions make greater amounts of water necessary

A good guide for fertilization is to observe plant growth. Leaves should be a healthy green; a pale green or yellow color may indicate nitrogen deficiency. Canes should grow well and be stout rather than spindly.
