Westland Sulphate of Iron (Plant Food for Ericaceous Plants), 1.5 kg

Value for money

It seems to be working on my rhododendrons, looking a lot healthier now

Recommend, it's very strong, be careful how much you use

Added this to the grass once a year and it helps build the durablity of the grass as well as adding to the greenness and toughness of the grass. Applying this around september time has helped with the quality of my lawn. Another advantage is it helps suppress the growth of moss in the lawn. I dilute it down and apply sparingly all over my lawn. It takes 5 boxes too complete the whole lawn but is definitely great value for money.

Dry effective

I am new to this product, and it is early days yet, to judge if it dies the job. I think the packing and usability would be much h improved if a measuring spoon or scoop was included. And I do not like opening system ‐ could be much better.

Excellent conditioner for most shrubs

My evergreen large potted plants were yellowing so I ordered this to reverse, in time, the colour back to green!Time will tell but it was easy enough to use and I'm eagerly awaiting long term results.
