Q.Why Are My Blackberry Leaf Edges Are Getting Brown/purple?
I have a fairly young Triple Crown blackberry plant in a container. New leaves are getting brown/purple edges. they do not die, but the plant doesn’t look happy. It is in a well drained potting mix, in a 20 Liter (about 5 Gallon) container. No fertilizer yet. Over watering? under watering? No evidence of pests. Anyone can help? Thx.

It appears as damage from overly wet soils. Fortunately, you can test for deficiencies or overload in nutrients in the soil to rule out nutrient imbalances or pH issues. These articles will help:

If you go through all test with no issues, then you may chalk this up to disease. I think that a soil test will reveal the issue, though.
