Castings start working the moment they hit your soil, so the sooner you start the sooner you start the journey to breathing health and life back into your soil.
For best results we suggest a healthy addition of high quality compost into your feeding schedule.

Application in dry environments.
Application of castings into the planting hole of young trees is crucial to ensure that the multitude of benefits that vermicast offers to strengthen and provide healthy growth from its early years is readily available right at the roots.
Application is highly advised if you are planting, wet or dry season, with or without installed irrigation.
Application of castings can be done year round, they works to stabilise moisture in soil helping to retain moisture in dry soils.
Microbes and worms in vermicast breed and function best in a slightly humid environment.
A bone dry sand will simply encourage worms to migrate and seek out more suitabe environments, not staying where you want them to do their work.
For best results in the dry season on small exposed trees, the instilation of irrigation prior to your application of vermicast is advised, otherwise waiting for the rainy season, so that the worms and microbes have the best environment to get established.
With this said, despite their fragile appearance, worms are supprisingly resiliant.
This is less of an issue in established trees whose branches above provide plenty of shade for the soil beneath.
