Title: I've heard that feeding radishes on coffee makes them grow better...?
Post by: P-Kasso2 on 28 January, 2016, 12:34:14 PM
I just heard this from an old allotmenteer the other day. Admittedly he is rather 'special' at times but old allotmenteers do often possess some surprising knowledge that others simply don't know about.

Even so, I have never heard that coffee helps radishes grow bigger and faster and better than before.

Quite the opposite. I'd expect any plant (radishes included) to immediately keel over if fed on coffee.

So who is right? Me? Or the ancient allotmenteer? Is there any scientific evidence one way or the other?

PS He didn't say whether fresh coffee or Maxwell House or a cup of decaf works best.

Firstly, I am assuming your allotmenteer buddy is referring to coffee grounds rather than freeze dried coffee granules or powder.

Radishes prefer a slightly acidic soil and coffee grounds are reputedly acidic; so their use might well be beneficial especially if the soil is erring towards the alkaline.

Coffee grounds, irrespective of brand, will provide nitrogen, potassium, phosphorus and other minerals that can support plant growth.

That makes sense...in just the same way that tea bags thrown on compost heaps work well. So long as me radishes don't get a caffeine blast and start getting twitchy on me I'll give it a try.
