Initiator tablets provide enhanced growth and long lasting protection against the damage caused by various insects that attack containerised newly planted and established plants. The tablets are designed to be placed in the soil adjacent to plants for normal maintenance or in the planting hole during transplanting of seedlings so that the growing plant can take up the fertiliser. Can be used on a variety of different kinds of plants, for example, palms, azalea, eucalypts roses, and lillypillies.
