Q: What is the main use of Supergro Plus 16-0-2?
A: Supergro Plus is designed to promote rapid greening and vigorous growth in lawns, gardens, shrubs, and trees. It’s especially effective when you need strong top growth and want to enhance overall plant health without adding phosphorus.
Q: Why doesn’t this formula include phosphorus?
A: Many soils already have sufficient phosphorus, and some regions restrict its use to prevent water pollution. This phosphorus-free formula is ideal for areas with those concerns while still delivering essential nutrients.
Q: How often should I apply it?
A: For best results, apply every 2 weeks during the growing season. Frequency can be adjusted depending on your plant or lawn’s specific needs.

A: Absolutely. It works well on vegetables, flowers, shrubs, and trees. Just make sure to follow appropriate mixing rates and avoid applying directly to edible parts of plants.
Q: Can I apply it in hot weather?
A: Yes, but it’s best to apply early in the morning or in the evening to avoid leaf burn. Avoid foliar spraying in the heat of the day.
Q: How long does it take to see results?
A: You’ll typically see greener, more vigorous growth within a few days of application, especially when applied as a foliar spray.
Q: Will it burn my lawn or plants?
A: Not when used as directed. Supergro Plus has a low-salt, non-burning formula that’s safe for routine use.
Q: Can I mix this with other products?
A: Yes, Supergro Plus can be tank-mixed with compatible fertilizers or microbial products. Always do a small compatibility test first if combining with other inputs.
