Root Boost
Root Boost builds root mass and fine-root development and speeds transplant recovery. Indole-3-butyric acid with calcium nitrate and seaweed extract stimulates rooting and helps young plants establish faster.

Pre-harvest and re-entry intervals are restrictions carried on pesticide labels. These products are not pesticides, so neither applies. For comparison, four hours is the shortest re-entry interval a registered pesticide can carry.
Root development accelerant from Vegalab Crop Science, powered by indole-3-butyric acid (IBA) · calcium nitrate · Sargassum seaweed extract. Root Boost targets Root mass, fine-root development, transplant recovery.
Indole-3-butyric acid, a root-promoting auxin, applied with calcium nitrate and Sargassum seaweed extract at the root zone. IBA drives root initiation and lateral branching directly; the calcium supports cell-wall development in the new roots. Plants establish quickly after transplant and develop a denser, deeper root architecture.

Why invest in roots at transplant?
The first weeks after transplanting set up the whole crop. A plant that quickly builds a strong, branching root system establishes faster, takes up more water and nutrition, and is far more resilient to early stress. Slow rooters stall, suffer transplant shock and never quite catch up - so supporting rooting early pays off across the season.
How does Root Boost drive rooting?
Root Boost (2-0-0; N 2.00%, Ca 1.50%) combines indole-3-butyric acid, calcium nitrate and Sargassum seaweed extract. IBA is a root-promoting auxin and initiates roots directly, the calcium supports cell-wall development in the new roots, and seaweed compounds support stress recovery - together building root mass, fine-root development and faster transplant establishment.

Apply to the soil or root zone at transplanting and through early establishment - the window where root stimulation translates most directly into a stronger, more resilient plant. Repeat through early growth to sustain fine-root development as the crop establishes.
Which crops is it for?
Root Boost has been tested on all transplants, tree fruit, vines and berries. It is most valuable for any transplanted crop and for young plantings of perennials, where establishment speed and root capacity shape the years that follow.
What does calcium nitrate add?
Calcium supports cell-wall development in the new roots, so the roots the plant builds are better formed and can work more effectively. Combined with the rooting stimulus of Indole-3-butyric acid and the stress support of seaweed, it helps the whole root-soil system establish well.
