Heather turning brown

Posted by donnaroe Ohio zone 5 (My Page) on

I purchased very small 6 inch plants of heather last year at aldis. It did okay, and was slow to green up this spring, but I fed it with osmocote and it greened up beautifully. I have four petunia plants next to it and water them religiously, and now the heather's tips are turning brown. (pretty bad) Are they getting too much water? They are in full sun for most of the day. I backed off the water a week ago, but I really don't know anything about heather and could really use some help. I don't want to loose them. They are planted in a raised bed at the base of a royal star magnolia tree. Thanks!

RE: Heather turning brown

I know this is an old post but...

It sounds like too much water. Heather (calluna) like moist but well drained acid soil & an open position. I nearly lost my heather last year to an exceptionally wet spring. The garden centre recommended light fertilization and crossing my fingers.

A temporary acidifier is 1/8 c vinegar in 1 1/2 q water, once a week. you can buy elemental sulphur later if you need to acidify the soil.
