Question by littbitt9

I have purple sage bushes that have been been turning black (leaves and branches). I have sprayed it for fungus and for insects numberous times this summer but it doesn't seem to help. I have cut the branches off that are the infested the most. We have had twice as much rain in our area that we would normally get so it has been a very wet summer. Is there hope or should I just dig them up?

Too much water can turn the leaves black. You can't control the rain, but you can amend the soil to make sure it drains as quickly as possible. If you have clayey soil, mix in some sand and some compost and then replant. This should help the soil drain a little better. Amend the entire planting bed, not just the planting holes and be sure to work the amendments down into the top 12 inches of soil. I think you'll see an improvement in their growth. Good luck with your garden!
