Potato Sack Garden


A big advantage of potato sack / bins is that the crop can be relatively isolated from pests.


If your garden soil is contaminated with eel worm, or blight for example, you can use a proprietary organic potato compost in bins or by making potato grow bags instead.


Any yard or patio will do as long as it gets plenty of light. Try to avoid windy situations. Containers in a warm and light situation produce earlier potatoes.


Bear in mind that it may be necessary to stake up the plants for support. 4 stakes with perimeter string will do. Although large tubs and grow bags can be moved if necessary, they will be too heavy to lift off the ground once filled.

Potato tubers are formed underground on side stems. So if the plant can be coaxed to produce side stems throughout the soil depth there is potential for a big harvest.


In practise this can't be relied upon. Even so it remains possible to obtain a bucket almost full of potatoes.


Be sure to keep filling the bin gradually leaving no more than 4" (12cm) green stems above ground. Also ensure the soil is moisture retentive and don't let it dry out.


Don't add excess nitrogen fertilizer.


Start growing as early as possible before the days get too long.


One final advantage of the potato sack-bins comes especially when using proprietary potato compost such as Humax with a late 'maincrop' - You can use the bin to store the potatoes.


Simply cut down the foliage and cover the potato bin to keep it dry.


Note that potatoes can be harvested on a cut-and-cum basis by feeling beneath the soil surface for tubers that are ready. This method will encourage small tubers to grow to full size.


Alternatively the crop can be harvested together at the end of season and stored in the buckets.
