Hi has anyone tried using Rock Dust as a feed for Alpines. I have a small Alpine House with a typical beginners selection after plants all in terracotta pots and sand plunge beds
Hi Sharon, I haven't used it but a little research confirms that it can provide trace elements and minerals and so may improve the health of your plants, especially if your compost mix is lacking in these. What it won't do, however, is feed your plants so when the nutrients in your compost have been exhausted you will still need to feed with a low nitrogen fertiliser. This only needs to be done every few waterings and at about a quarter of the strength suggested on the packaging. Hope that helps.
Thank you I will give it a try, We also sell Chempak no 8 Low Nitrogen feed in our allotment trading hut, as my plunge beds are in three isolated sections then I think a little experimentation is on the cards
