Inject 1 ml every 4″ around the base (flare) of the tree. See label for details.

Timing of Nutribooster Injections

Injections may be made any time during the growing season. However, as summer ends, green-up will be less likely to occur because the leaves become less responsive as they age. The best time to inject is spring through early summer.
