Sprouting potato tubers before planting them will speed up the growth of your young plants, bring the harvest forward by a few days to a few weeks, and improve the harvest.
This technique does not apply to potatoes purchased pre-germinated in a garden center and therefore ready to plant.
Potato sprouting applies to seedlings purchased ungerminated and to potatoes from the previous year.
Germinate potatoes from ungerminated plants
Here's the right technique to help your potatoes sprout before you plant them.
- Use a crate or in an egg carton
- Store the potatoes without stacking them
- If a germ exists, it must look upwards
- Arrange the potatoes in the light, in a dry, cool and airy place
- The ideal germination temperature is between 10 and 15 °
- Germination time lasts about 4-6 weeks
Use your own seed potatoes for germination
It is quite possible to use potatoes from the previous year to germinate them.
- The grubbing takes place about 4 weeks before the potato harvest
- Select disease-free potatoes from vigorous plants
- Let the potatoes sit on the ground for a few days
- Finally, select the tubers that have resisted the best, without rotting
- Finally, store them in a cool and ventilated place until the following year
- Around February-March, start germination as explained above.
A few weeks after starting to germinate your potatoes and when the soil temperature is around 12 °, it is time to put them in the ground and grow your potatoes for a good harvest!
A good way to find out the ideal planting time is when the sprouts turn purple ...
