| The lower branches on my tiger eye sumac now have leaves that are turning more yellow than the regular yellow tint it gets in the summer. It is slowly making its way up to the top branches and causing the leaves and the branches to die. It doesn't look like a typical lack of iron and I've given it plenty of nitrogen. Any ideas what is causing this? |
| Insufficient sunshine or poorly draining soils can stress a sumac to the point that the foliage changes colors too early in the season. Try watering deeply only once a week during the first year it is in the ground and then only every 10-14 days from the second year on. Sumac is drought tolerant and too much water can stress the plant. Best wishes with your garden! |
