Superthrive - The Original Vitamin Solution for plants
Superthrive – The Original Plant Vitamin Solution, Since 1940
Some products last because of clever marketing. Superthrive has lasted since 1940 because gardeners keep reaching for it at exactly the same moments: repotting day, a plant that's sulking after a move, a tray of seedlings going out into the world. It isn't a fertiliser. It's a concentrated vitamin B1 and kelp tonic that helps plants cope with the stress of change, so they get back to growing sooner.
When to Reach for It
- Repotting and transplanting: helps reduce transplant shock and gets new roots moving
- Stressed or struggling plants: after a move, a cold spell, over- or under-watering
- Seedlings and cuttings: a gentle boost through their most fragile weeks
- Seed and bulb soaking before planting
- Cut Christmas trees: in the water of the tree stand
How to Use
| Use | Dose |
|---|---|
| Regular watering (houseplants, veg, hydro) | About 1ml per 4 litres of water, weekly or every other week |
| A single houseplant | 1 drop in a cup (about 120ml) of water |
| Transplanting flowers and tender plants | 1ml per 4 litres, before and after planting |
| Transplanting trees and woody shrubs | Up to 5ml per 4 litres, before and after planting |
| Seed and bulb soak | 1ml per 4 litres, soak for 15 minutes |
Shake well before use. It works alongside any feed, in soil, coco or hydro, and as a foliar spray.
🌿 Rose's Pro-Tip: water the plant with Superthrive the day before you repot it, and again straight after. A plant that goes into the move well-watered and comes out of it well-watered loses far fewer leaves to the shock.
Why It Lasts So Long
Superthrive is extremely concentrated. At 1ml per 4 litres, even a small bottle treats hundreds of litres of water, so one bottle sees most gardeners through years of repotting.
Pairs well with: Hygrozyme and Great White mycorrhizae for a healthy root zone.
