Superthrive Vitamin/Hormone Plant Growth Stimulant
DetailsSUPERthrive is a highly concentrated plant growth stimulant that helps to greatly improve transplanting success and revive plants recovering from hail damage, frost and heat stress. Thoroughly soak the soil in the planting hole after transplanting. Then use it again 2-to-3 times at two week intervals: use at same frequency when reviving stressed or damaged plants. To improve your results, we highly recommend combining SUPERthrive with Sea Com-PGR liquid seaweed to give plants the synergistic boost that occurs when using the two products together. You'll be astounded how quickly plants rebound from damage and stress to begin active growth. A little goes a long way; mix 1/4 tsp. per gallon of water. One 2-0z. bottle treats 48 gallons of water. SUPERthrive is not a fertilizer but can be added to liquid fertilizers to improve root uptake of the nutrients.

Comments about High Country Gardens Superthrive Vitamin/Hormone Plant Growth Stimulant:
I LOVE this product!!!! I use it when I water in new or transplanted plants. It is also AMAZING to use for annuals in containers or window boxes that get stressed with too much heat/not enough watering. I had great success reviving my window boxes in Massachusetts this summer (there is a drought) from full on wilt after vacations when they completely dried out. The boxes look great even now. Seriously, I will ALWAYS use this product. It is also great when transplanting plants from one garden to another (when they wilt from being moved) or if they have been transported (mail-order plants). HIGHLY RECOMMEND!!!!

Q & A
USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
