STX DIY (StressX) From Carbon Earth Company is a specialty potassium fertilizer. Potassium plays an important role in plant performance, this product capitalizes on biochar's ability to provide a housing site for potassium ions - meaning potassium where you need it for longer.
STX DIY is formulated for lawns with potassium deficiencies by supplying K in a low salt index form. This product is also great for lawns under stress in summer from heat or those recovering from insect or disease pressure.
This product also contains 4% iron to give the lawn a nice greenup without inducing extra top growth. STX DIY is a great product for summer applications.
