Bonzer Gromate All Purpose: Seaweed & Humic Acid Liquid Fertiliser
Bonzer Gromate All Purpose is a liquid seaweed and humic acid fertiliser designed to build stronger roots, healthier soil and more resilient plants across the whole garden. It works as both a plant tonic and a soil conditioner, making it an easy all-rounder for lawns, vegetables, fruit trees, flowers, natives and pot plants.
Rather than just feeding the plant, it feeds the soil and the root zone. The seaweed component acts as a natural biostimulant that helps plants establish, settle after transplanting and cope with stresses like heat and dry spells, while the humic acid improves the soil's ability to hold and release nutrients, so whatever you feed your plants works more efficiently. Together they encourage stronger root development and better nutrient uptake.
Because it is a gentle, all-purpose liquid, it is safe to use regularly through the growing season and won't burn plants when used as directed. It is handy at planting and transplanting time to help roots take hold, and as a pick-me-up for tired or stressed plants. Being a concentrate, it is diluted in water and either watered onto the soil or applied to the foliage.

How to Use
Bonzer Gromate is a concentrate, so dilute it in water at the rate on the label before applying. As a general approach, water the diluted solution over the soil and root zone, or apply to the foliage as a spray, and reapply through the growing season. It is especially useful at planting and transplanting to help roots settle, and as a regular tonic every couple of weeks during active growth. Water in well after soil application. Always follow the label rates and directions for your plant type and situation.
Getting the Best From It
Apply in the cooler part of the day, early morning or late afternoon, rather than in the heat, and to moist rather than bone-dry soil for best uptake. Because it works on the soil as well as the plant, regular light applications tend to give better long-term results than occasional heavy ones. Use it alongside your normal fertiliser program, since seaweed and humic acid products are there to improve root health and nutrient efficiency rather than to replace a complete feed. Shake well before measuring, and reseal the cap after use.
