1. I note that you produce both Osmocote and Miracle Gro continuous feed granules. Please would you let me know what the difference is between the two. One is more readily available for me than the other.

2. I have bought Osmocote (although Miracle Gro would have been easier to buy). I am having difficulty in working out the measurements for my pots.
I have plant pots of 9", 12" and 14". Please would you tell me how much I should use for each of these. I note that a handful is described as being about 30 grams.

3. I cannot quite understand how to use the Osmocote. I have watched youtube videos but it remains unclear to me, as do the instructions. I have just planted a new hydrangea in a 9" pot, and put compost at the bottom, sprinkled some Osmocote on top of that, sprinkled about 1cm more of compost on top, sat plant on top, and then back filled with more compost around the side of it, with some Osmocote mixed in with it. Does this sound about right? Will the water take the nutrients down into the roots when I water? I used one handful for this, which I suspect is too much. Will this harm the plant or roots?

Thank you for your help.

Continuous Plant Feeds

Posted 08 Feb 2017

Hi Bertie & George,

Osmocote Controlled Release Plant Food contains 16:5:17 and Miracle-Gro All Purpose Continuous Release Plant Food contains 17:9:11.

For mixing Osmocote in compost when potting up use 25-45gms/10lt of compost. Use the lower dose for bigger pot sizes or for sensitive/young plants. Without knowing the height of the pot it is difficult to say how much to use.

When potting up, mix the Osmococte with the compost in a bin then put some in the base of the pot, place the rootball on top making sure the top of the ball is 15mm below the rim. Fill the remaining space with the mix gently firming with your fingers and water the compost. 

It is important to use any feed as accurately as possible to avoid causing any harm to the plants.

For feeding existing plants in pots we suggest using Osmocote Controlled Release Plant Food Tablets

Kind Regards
