A coffee lover I am not, but I wasn’t going to let that deter me from this month’s Urban Jungle Bloggers theme, especially since I’ve discovered it may very well be quite beneficial for our green and growing friends…
I’ve been looking at feeds for my house plant babies for a while – they make me happy, so I want them to be happy too! I heard that coffee grounds can be good for plants as they increase the moisture hold in soil and add nitrogen, which leafy plants love for bright greens & strong stems.
Coffee also contains calcium & magnesium which are good for plant health. However, it can boost the soil acidity so should be used in moderation, particularly with succulents (and probably not best for cacti, as they both prefer a relatively neutral PH).
I’m a little bit nervous but willing. I’ve decided to try a liquid solution from a full strength cup which is then diluted 1 part liquid coffee to 3 parts cold water (it looks like weak tea). Since it’s not really growing season here, I’ll use it once a month with my succulents for now (plus water in between), and perhaps bi-weekly for my Monsterra, Rubber Tree & Snake Plant. We’ll see how things go.
Other ideas for plant feed I’ve come across are…
\\ crushed egg shells worked through soil for calcium
\\ cooled water from boiled potatoes & pasta for adding starch
\\ very weak milk solution (as in fill a finished milk bottle with water – that weak) for adding calcium
\\ finely chopped peel for added nutrients. Banana adds nitrogen, potassium, calcium, sulfur, phosphorus, magnesium and sodium. Orange adds nutrients & nitrogen.
Have you tried any of these and did they work? I’d love to hear your house plant feed secrets & successes!
