Planting Seed Potatoes
As we mentioned earlier, potatoes require warmth. Thus, you shouldn’t start planting until the last frost has passed. It is crucial that the soil is warm enough to allow potato seeds to grow. The soil temperature should be above 40F (4 C) otherwise your plants will not grow.
You can use your garden soil if it is a good quality soil. If it is not, it is recommended that you buy some good quality soil. Fill 4 to 5 inches of the container with soil. Put the potato seeds on the top of the soil with the eye buds facing upward. Then, add another 5 inches layer of soil to cover the potato seeds
Growth requirements of potatoes
The only negative when you grow potatoes in small spaces like this is the constant need to water. Potatoes need to be consistently moist, so a daily dousing during summer’s heat is an absolute must.
Fertilizing
Potatoes are not heavy feeders, thus applying a natural fertilizer is enough. Well-rotted manure and compost are sufficient to provide your potatoes with the nutrients they need to grow. However, for optimum growth, you could apply an organic liquid fertilizer. You shouldn’t fertilize your plants more than once a month.
Potatoes need a lot of potassium to grow. Therefore, you should avoid applying too much nitrogen fertilization to them. Nitrogen fertilizers will promote foliage growth rather than potato growth.
Harvesting
When the leaves are yellow and you start seeing blooms, you can start harvesting your potatoes. Don’t wait too long to harvest otherwise you will be harvesting dry potatoes.
This is how to grow potatoes in containers successfully. Follow these steps and you will enjoy a heavy yield of sweet delicious potatoes.
Enjoy growing potatoes!
