Root Feeding - Knowledgebase Question

Pasadena, Te
Question by gmlwilli

I have been using granular, water soluble All Purpose Miracle Grow to root feed the plants in my yard. Two nursery men have advised Miracle Grow, when used regularly, will leave a salt residue in my soil. Should I use liquid plant food in my root feeder? What do you recommend?

Any fertilizer has the potential to leave a salt residue if you apply in the same places over and over again. Changing the brand of fertilizer you use won't make any difference but moving your root feeders to different spots can keep salts from building up in the soil. Flooding the soil periodically at the base of the root feeders can help leach out any salt build up. Hope this information is helpful.
