Coffee Grounds for the Potato
This is an update to an earlier post about some of the things I am doing with growing potatoes in car tires, with a coffee compost blend. In the month and half since then, there has been considerable growth of the potato plants.
Under the grass clippings is a mixture of coffee compost and leafmold. Using coffee grounds with potatoes seems to be working very well.
This second stack is going even better. The leaves and stems are in great condition, which was not the case last year. To date, I have not feed the plants anything besides what was already in the compost.
Another potato plant in coffee compost, this time in a polystyrene container. You can see some potatoes growing on the right, only a few inches below the surface. This container might well be full of spuds in a few months! In this one there is mostly fresh soil and vermicast, which seems ideally suited to growing potato.
The quality of this soil is providing me with healthy and productive plants, sure to provide the kind of fruits and vegetables that you just can’t buy in a shop. I might even haul a bag of the spuds to the coffee house that gave me all that ground coffee.
How to Grow Potato
I’ve been asked a few times how do I grow potatoes, and the whole thing is easy for home gardeners at any level. You could start with the potatoes that you buy from the supermarket, leave them out in non-direct sunlight until they start producing shoots in the potato eyes. A week after that starts, get them four inches into the ground with the shoots facing up, water the soil, and leave it be.
