Q.pachysandra fertilizer
Can I use Miracle-Gro Shake N’ Feed on my pachysandra at the start of fall? Some of it is turning yellow and I think it may need some nitrogen. Thanks

Fertilizing your plants in the spring is recommended.
Scatter a handful for every 4 square feet of garden bed, but avoid getting the fertilizer on the leaves.
If you are questioning your nitrogen levels, a soil test is the only way to determine this. Fall is a good time to do a soil test.
Yellowing leaves could indicate watering issues, pests or disease.
Here are some link with more information.
