The Big Three: Balancing NPK Without Frying Your Roots

• The Growing Stage (Weeks 1 to 4): Your tomato needs plenty of Nitrogen (N) to build a thick main stem and lush green leaves. Top-dress each plant pot with exactly 150ml of Microtek Worm Nuggets per 16L of container space, scratching it gently into the top layer of your soil to deliver slow, non-burning nutrients.
• The Flowering & Fruit Stage (Week 5 Onward): The second you see clusters of yellow flowers appear, the plant’s need for Nitrogen drops significantly, while its need for Potassium (K — for fruit size and sugars) and Phosphorus (P — for flower count) sky-rockets. Introduce a clean, organic phosphorus booster like Bio Guano or Supernatural to jump-start heavy fruit development.

Stopping Blossom End Rot: The Calcium Trick

The single biggest failure home tomato growers face in Australia is Blossom End Rot. This is where the bottom of the tomato turns black, leathery, and completely rotted out. This is not a bug attack or a disease, mate—it is a simple Calcium deficiency inside the fruit walls. Calcium is a lazy, slow-moving mineral that cannot travel through the plant cells on its own; it relies entirely on the flow of water via transpiration (water being drawn up by the roots and evaporated out through the leaves like a natural straw).

To ensure plenty of natural calcium is bound directly into the soil, our award-winning Easy As Organics Living Soil comes pre-blended with high-grade organic limestone and gypsum. To make sure the plant can actually grab that calcium during a scorching 40°C afternoon, inoculate your roots with Mykos Mycorrhizal Fungi. This wraps a microscopic web of beneficial fungal threads around your roots, expanding the total root surface area by up to 300% for stable, continuous water and calcium uptake.
