Sweet Potatoes 'Okinawan Purple' / 'Molokai Improved'

AVAILABLE FROM NOVEMBER AS TUBERS AND FROM MAY AS PLANTS.
Elongated, dark purple, slender tubers, the purple tuber flesh is particularly popular and contains extra healthy ingredients. This variety is not suitable for outdoor cultivation, so a plastic tunnel or greenhouse will provide a solution. Unfortunately, purple varieties for outdoor cultivation in our climate do not yet exist, but we are working on it…

Our active grower is constantly looking for the best varieties of Sweet Potatoes for open ground or for the greenhouse. In May-June, he offers us young plants, and in November, the tubers from which you can grow beautiful plants yourself.
WHAT DO YOU DO WITH THE PLANTS?
If you haven't grown plants yourself from a tuber in winter (see below), we have young plants available from May to plant out (after the last chance of night frost). The fast-creeping plants need space; plant them 40 cm apart and 80-90 cm between rows. Large raised beds are beneficial for soil warmth and thus for yield. Regular watering is very important during dry periods; professional growers often use drip irrigation. Harvest at the latest before the first night frosts.
WHAT DO YOU DO WITH A TUBER?
Just put it in the ground outdoors? No! Cultivation is a little different from growing seed potatoes. It's a fun job to do indoors, in a warm spot. (From May, when the weather is warm, it can also be done directly outdoors)
You need a seed propagator with a high lid, or you can use any tray or pot that can accommodate one or more tubers lying down. In the latter case, it is wise to create a frame over which you stretch plastic for warmth and moisture retention.
Place the tubers (lying down) in cocopeat 809620-zaaigrond-cocopeat-briketten
2/3 submerged in the soil. Keep them well-lit, moist, and warm; the tuber will produce many shoots. After 5-10 cm of growth, you can break or cut these off close to the tuber and directly insert them into a pot or a swollen Jiffy-7 pellet. Each cutting will root very easily.
There are also other methods, for example in water; just watch this video on YouTube.
