CalMag 1L | Calcium & Magnesium Plant Additive with Beneficial Iron

This is a great product and does what it says on the bottle. I ordered it after getting the beginning of some tomato blossom end problems. A single application not only cured this but improved the general health of the plants. I will be using it fortnightly from now on . When I bought it I thought it was a bit pricey but the small amount used per application means it should last well.

Excellent product , easy to use and it does the job it is designed for at a good price.

The product seems to have fixed the issue which I caught early of blossom end rot on my tomatoe plants. The only problem that I had was that the measuring cap had a big hole in it so it couldn't be used.

It's good stuff when needed. My water is very soft and needs cal mag i use 1mill per litre at every watering as it stops a lot of problems.

Great stuff this bottle goes a very long way will definitely order more when needed which won’t be for a while as I still have loads left

Very effective as a drench for exhibition celery plants. Use regularly to prevent heart rot. I used to use Chempak calcium which no longer seems available but the Calmag product is better and gives strong clean plants. also good for tomatoes preventing blossom end rot.

Very pleased with this 😊

Very good cal mag best price online and much needed
