Can I use these products together?

yes you can. We recommend using these products together for best results.

Is the Health-mix a fertiliser?

How much Health-mix do I need for my hedges?

One tablet dissolved in one litre of water will cover an area of 10m2.

How much Grow do I apply to my plants?

500g does 10m2, ife you have pots you can apply approx 50g per 1m2 pot

Do I need to water in Grow?

Yes you should water in Grow after applying. Grow is a fast acting fertliser and will rapidly break down as soon as it is watered in.

My bux has dulled and started to brown off after using our product

Hi there Stan!

Thanks for getting in touch! I'd like to clear a few things up. For treating bronzing leaves, we actually recommend using Topbuxus Health-Mix instead of Topbuxus Grow.

It's also possible that your plants might have a root disease, depending on the bronzing pattern you're seeing. Correctly diagnosing the issue is key to success, so we'd love to help you with this. Could you send some photos of your plants to This will help us assess their condition more accurately.

In the meantime, I suggest checking out our care guide, YouTube channel, and Instagram for more resources. We've put a lot of effort into providing helpful information to ensure your plants thrive.

Looking forward to assisting you!

Health mix and grow

I have used both the heath mix and Grow on my English Box on one part to see the differences to my hedge, the results are fantastic the part that I treated is beautiful, now I have used it all over, I thought I was going to loose the hedge until I found this product it was browning and not growing much but now it’s green and healthy looking
Thank you so much for this Product

Katherine Carey
Amazing product

I generally view before and after photos in advertising with cynicism. Using Top Buxus products has resulted in amazing growth and repair . I know the before and after photos are real!

Pam Fortey

It has all taken a while to work

Hi Pam! It's amazing how plants can surprise us with their own schedules, isn't it? From micro climates to watering routines, there's so much that affects their growth. And you're absolutely right about patience being key in gardening – sometimes reality doesn't quite match our expectations, but that's all part of the journey!

If you ever have any questions or need advice, we're here to help. We take pride in assisting fellow gardeners with troubleshooting any issues they encounter. It's great to hear that you eventually saw the results you were hoping for! How long did it take before you noticed those changes?
