02Why it happens

03What to do

1. 01 Apply wood-based material as a surface mulch instead of digging it in.
2. 02 If already dug in, water with diluted urine at 1:10 or a liquid nitrogen feed.
3. 03 Do not add more high-carbon material to the affected bed this season.
4. 04 Compost chips for a year before use in soil, or keep them on the surface permanently.
