Check these first

- Check the stem base for soft or dark discoloration.
Likely causes
Overwatering
Most likelyHow to tell: The soil stays soggy for days and the base of the stem feels soft or mushy. Leaves may turn yellow or brown before dropping.
What to do: Stop watering immediately and let the soil dry out completely. If the soil is heavy clay, you may need to transplant the sagebrush into a well draining mix of native soil and gravel.
Poor Drainage
PossibleHow to tell: Water pools on the surface after rain or irrigation. The plant sits in a low spot where water collects.
What to do: Create a small mound of soil to elevate the plant base above the surrounding ground. Ensure the planting site has excellent drainage by mixing in coarse sand or small rocks.

When to worry
If the entire base of the plant is mushy, it is likely too late to save it. Some minor wilting after a heavy rain is normal, but it should recover as the soil dries.
Stopping it coming back
Only water your sagebrush once every 14 to 30 days once it is established. Always plant in full sun with gritty, fast draining soil.

Questions people ask
