DescriptionDetailsDelivery

Rootgrow Tomato Starter is a practical way to give your young tomato plants the best possible start, delivering essential biology often missing from standard composts and bagged growing media. These 100% peat free, compact biscuits are made from compressed coir and expand when watered, releasing nutrients and beneficial organisms directly where roots need them most.

Each biscuit contains five active ingredients designed to support strong, productive growth. Rootgrow mycorrhizal fungi develop a natural relationship with plant roots, creating a secondary root system that improves establishment, boosts flowering and fruiting, and helps plants recover from periods of drought. Beneficial soil bacteria work to fix nitrogen from the air, providing a steady and reliable nutrient source, while slow release nutrients continue feeding plants for up to four months.

Seaweed meal is included to encourage vigorous root development, complemented by a blend of bio-additives such as humates and biochar, which help nourish and sustain beneficial soil microbes. Together, these elements create an ideal environment for healthy, flavour-rich crops.

How to use: Place one biscuit into the soil, pot, basket or grow bag, position your young plant directly on top, backfill and water thoroughly. Use one biscuit per plant.

FAQs

Learn more about how to use a tomato starter mix.

How to use Tomato Starter?

To use your Tomato Starter, place one compressed coir block in the base of the planting hole and cover lightly with soil or compost. Position your tomato plant on top and water thoroughly to help the block expand and activate. Use one block per small pot, grow bag, or plant in the garden, adjusting the amount for larger containers as needed. Apply only once at planting to encourage strong root establishment and healthy growth throughout the season.

What promotes root growth in tomatoes?

This mix delivers essential tomato nutrients to help your plants grow strong and healthy. The Tomato Starter features mycorrhizal fungi that connect with roots to make them larger and more resilient, beneficial bacteria that capture nitrogen from the air, and seaweed meal to spur rapid root development. Added humates and biochar also sustain vital soil microbes around the roots. When the compressed coir block expands with water, these tomato nutrients reach the root zone directly, supporting bigger harvests and greater drought resilience.

Can Tomato Starter be used for established plants?

Tomato Starter is primarily intended for use at planting to establish the beneficial root-fungi relationship. For established plants, it is recommended to use Liquid Tomato Fertiliser, a high-potash feed to promote bumper tomato crops. This feed supports fruiting stages by delivering potassium to strengthen stems, improve disease resistance, and produce fuller trusses once roots are established.
