- These rates are intended as guidelines. Suståne encourages a trial prior to changing any fertilizer program.
- Do not steam sterilize container mix after fertilizer has been incorporated.
- Do not store container mix more than two weeks after incorporating fertilizer. Plant material can be damaged from salt accumulation.
- Monitor electrical conductivity (EC) of container substrate throughout production cycle.
- If mix is stored longer than two weeks, leaching container mix may be required to remove accumulated salts
- Adjust application rate as needed.
