Potatoes- what on earth?

Potatoes – what on earth?

We often hear the phrase ‘Earthing up’ whilst speaking about potatoes, especially around this time of the year. It is much simpler and more useful than it may sound!

Earthing up

Earthing up or ridging as it is sometimes known, is simply drawing up soil into a ridge above the row of planted potatoes. You can do this as soon as foliage emerges above the surface.

Why?

 For container potatoes

Maybe you have decided to grow potatoes in sacks or containers, if so the process of earthing up still applies- simply add layers of compost in stages as the stems begin to grow. Carry on until you reach the top of the container. A good heap of about 8 inches / 20-cm should be enough.

Don’t rush

After all your efforts with earthing up, don’t give in to the temptation of harvesting your crops too early. For early potatoes be sure to wait until the flowers are completely out and for the main crop variety you can hold back until the foliage begins to turn yellow.
