Spring/Summer is finallly upon us. This years tip is to apply crabgrass control your first two applications of fertilizer this year. We are predicting a very bad crabgrass season! As rains lessen and heat increases typical lawns slow down where as crabgrass has such a developed tap root and basic root structure it can retain water and reach deeper allowing it to flourish in harsh climates as well as having a large leaf it absorbs twice as much sunlight. so BE WARNED.... its easier to prevent than to stop.
Use fertilizer with lower nitrogen and higher potassium., Try and find a good fertilizer with some iron for that deep green!!
