Empathy Bulb Starter with rootgrow™ Mycorrhizal Fungi 500g is a biologically active planting treatment developed to give bulbs, corms and tubers a strong start. At the heart of the formulation is rootgrow™ mycorrhizal fungi, which establishes a secondary root system in association with the plant's roots, helping the plant access additional water and nutrients from the surrounding soil.
The formulation also combines vermiculite to support drainage and aeration in the root zone, seaweed meal as a source of naturally occurring auxins associated with root development, and natural humates, which provide organic acids for the treated bulb and soil microorganisms. This 500g pack can treat up to 50 bulbs, making it a useful companion product for seasonal bulb planting.
Supports the roots from planting time – rootgrow™ mycorrhizal fungi works in association with the developing root system.
More than a conventional planting mix – combines beneficial mycorrhizal fungi with vermiculite, seaweed meal and humates.
Helps the root zone – vermiculite supports good drainage and soil aeration.
Easy to apply – simply measure into the base of the planting hole before planting.
Excellent pack performance – the 500g pack treats up to 50 bulbs, depending on bulb size and application rate.

Vermiculite is included to help provide good drainage and aeration around the developing root zone.
The mix contains seaweed meal, a source of natural auxins that support root development during establishment.
Natural humates provide organic acids that benefit the treated bulb and soil microorganisms.
