Mixing UltraGrow Bio Fertilisers: What You Need to Know

The great news is that most UltraGrow bio fertilisers are cross-compatible, meaning they can be mixed and applied together without any special requirements. Simply follow the basic guidelines, and you’re good to go!

If you’re mixing a product from another brand or have concerns, it’s always a good idea to conduct a jar test first.

Key Application Tips

The most important factors to keep in mind are the size of the area you need to cover and the recommended application rate (e.g., 100ml per 100m²). As long as you apply the fertiliser at the suggested rate over the appropriate area, and use the minimum amount of carrier water, your application will be effective.

Proper Mixing Procedure

When mixing liquid fertilisers in a sprayer, always add the water first. This reduces the risk of fertiliser splashing back, which—while our products are primarily organic and safe—no one wants a mouthful of seaweed! Adding water first also helps prevent the solution from frothing or bubbling, which can lead to overflow.

How to Conduct a Jar Compatibility Test

If you’re unsure about product compatibility, especially when using fertilisers from different brands, follow these steps for a quick jar test:

1. 1. 1. Read the Labels: It’s essential to know the composition of the products you’re mixing. This ensures you’re aware of potential interactions.
      2. Shake Liquid Products: Shaking liquid fertilisers before mixing ensures that any settled ingredients are evenly distributed.
      3. Prepare the Jar: Adding 500ml of water to a 1L jar provides enough carrier water for the products to dissolve properly. This simulates the dilution and mixing process in a sprayer.
      4. Mix in Order: Adding products in the same sequence and ratio as in the sprayer helps you test the actual mixing process you’ll use. A teaspoon is an appropriate amount to represent small-scale mixing.
      5. Shake and Wait: Shaking and letting the solution sit for 30 minutes allows you to observe any signs of incompatibility, like precipitation or separation, which indicates that the products may not mix well together.

This method effectively mimics how the fertilisers will behave when mixed in a tank. If no issues arise during the test, you can be confident that the mixture will be stable in the larger spray tank.
