Sweet potatoes are a very good vegetable, can be used as the main food to fill hunger, 30 years ago, our family would grow a field of sweet potatoes every year, and each stubble is about a month apart, so that you can eat sweet potatoes without interruption, endless sweet potatoes, and you can pick them up on the street to sell.
After we have been planting sweet potatoes for a long time, we have summed up a lot of experience, and the following will share with you three ways to keep sweet potatoes, let's get to know each way to keep seeds, understand the advantages and disadvantages of each way of retaining seeds, and planting sweet potatoes in the future will not have to worry about no sweet potato seedlings.
1. Keep the roots of sweet potatoes and raise seedlings next year
Keeping sweet potato roots is the most common way in the north, because the north is relatively cold, sweet potatoes cannot be planted in winter, and sweet potatoes can only be planted again after the snow melts in the next spring (except, of course, greenhouse planting); Therefore, it is impossible to nurse seedlings in winter, so we can only wait until the snow melts the following year and the weather warms up before starting seedlings.
However, sweet potato seedlings are not easy to preserve, so sweet potato seeds can only be retained by retaining sweet potato roots; Sweet potato tubers are easy to preserve, not easy to rot, and can be stored all the way to the next spring.
Of course, if you don't have potato seedlings, but you want to plant sweet potatoes, you can also use sweet potato roots to cultivate seedlings, and then separate them for planting after growing sweet potato seedlings.
In short, if it snows in winter in your area, you can use the method of leaving sweet potato tubers to keep seeds for sweet potatoes, and then start seedlings in the next spring, and plant seedlings after breeding.
2. Leave sweet potato vine eyes and nurse sweet potato seedlings
As we all know, sweet potatoes are a crop that can reproduce asexually, and sweet potato vines can grow indefinitely, but sweet potato vines must have knotted eyes; Based on this, we can also keep the knots of the sweet potato vine as sweet potato seeds, as follows.
First, we select some disease-free robust sweet potato vines, remove the leaves on them, then cut them in the way of two segments, throw them into grass and wood ash and brush them again, and finally bury them in sand for preservation; If it snows in winter, you also need to cover the perimeter with a plastic film to prevent frostbite of the sweet potato vine eye; The seedlings will be dug up again in the spring of the following year.
Retaining the sweet potato vine eye to keep seeds for sweet potatoes, good treatment, can save a lot of sweet potato roots, is a very recommended way, but not suitable for snow-free areas in the south.
3. Keep sweet potato vine and dock seedlings without gaps
For the southern seaside area, sweet potatoes can be grown all year round, because the temperature will not be very low, and there is no need to worry about frostbite of sweet potatoes; Therefore, every ten days before harvesting sweet potatoes, we can cut some sweet potato seedlings to seedling, in fact, strictly speaking, planting, but in other plots, according to the normal steps and methods of planting sweet potatoes.
In this way, we can achieve gapless docking seedling sweet potatoes, and there are sweet potato seedlings to plant sweet potatoes all year round, so there is no need to worry about the problem of planting sweet potatoes without sweet potato seedlings one day; If your home is also southern and it doesn't snow in winter, you can use continuous planting to preserve sweet potato seeds.
Sweet potato seeding is so simple, you can decide which method to use according to the local weather conditions, so as to ensure that there are always sweet potato seeds to plant.
