The Q&A Archives: Do I sacrifice my lanarth hydrangaes?

Question: Lanarth hydrangaes (3) were planted last May, facing north with minimal sun. I have a drip watering system and planted in compost and soil. The first season many leaves yellowed and the blooms were minimal. This year the leaf growth has been minimal compared to other hydrangaes in other locations. Would we be better off finding a new location for these and planting a more hardy variety in its place or will they perk up? They are in the front of the house. Please advise. Thank you.

Answer: Based on your description I suspect they may have yellowed due to planting too deeply and/or overwatering and lack of direct sun combined, as well as possibly a fertility problem -- either over or under supply of nitrogen or possibly a micronutrient deficiency. Blooming last summer would have been dependent on buds formed on growth from the year before, so a one year performance is not really a fair trial. On the other hand, they do need some direct sun to bloom well. A few hours of morning sun up to all morning sun is about right. I would consider moving them and I would not re-plant with hydrangeas there.
