The yam belongs to very thermophilic plants. That is why the planting time comes in mid-May or early June, when there is no threat of frost, and the soil warms up to the required temperature of +15 degrees. Planting can be done earlier, but only in greenhouse conditions.
The soil
Preparation begin in the fall. The soil is dug up to a depth of 15-20 cm. To prepare a suitable soil mixture, it is necessary to take loose soil, humus and coarse sand in equal parts.
Next, nitrogen, phosphate and potash fertilizers are introduced into it. This may be rotted manure or compost, superphosphate or potassium sulfate.
Inventory
For different ways of growing yams will need:
- a box or container for germination;
- glass containers;
- disposable cups.
All inventory in which the sweet potato will be germinated must be thoroughly washed, dried and disinfected. Boxes and plastic containers are treated with special solutions., and glass containers can be ignited in the oven.
Material
Yam is planted with cuttings, and for this they can be obtained in two ways:
- buy ready;
- grow from a tuber.
Before growing planting material must be pre-treated, disinfected. This will increase the yield and save you from possible diseases. To process the tubers, it is necessary to soak in a solution of a fungicide or biofungicide.
Choosing a place
The plot on which the sweet potatoes will be planted should be well lit and located on the south side. Best of all, if from the north side of the ridge will be closed buildings or a fence. This will give a good warm.
In no case can not plant a plant on the site, even with the smallest shading. Batat does not tolerate the shadow. Also the site should be protected from the winds.
Scheme
The plant has the ability to curl and climb, so it needs a wide distance between the rows. The best distance is 100 cm, with a tolerance of plus minus 25 cm. The distance between plants should be at least 30 cm, and best of all 40-50 cm. Compressed circuit 75 to 35 or 50 to 50.
The distance depends on the variety of the planted sweet potato. The optimal landing pattern is 75 by 50 and 100 by 35.
Tubers
This method of landing is used in January or February. Need to buy a few tubers. They will be enough for a small area. Disinfect tubers with a weak solution of copper sulfate. Next, prepare the box for the germination of tubers, at the bottom of which make drainage holes and set the pan. Then follow these steps:
- Prepare the soil mixture and calcine it in the oven.
- Fill the third of the box with soil, top with 3 cm of sand.
- Disinfect the tubers and place them in the ground.
- Squeeze the tubers into the ground and sprinkle with sand for 3-4 cm.
- Water the soil regularly.
- Keep the box at a temperature of +18 to +27 degrees.
- After 30 days, there are 10 cm shoots that need to be separated and put water, before the roots.
- After the appearance of the roots, plant shoots in separate containers (you can use glasses).
- Sprouts removed up to 7 times, after 10 days.
- In the spring you can land in open ground, provided that the temperature of the soil is +15, and air - +25.
- On the site to prepare 15 cm of the hole and pour them. The planting pattern is 40 cm by 70 cm.
- Deepen the seedlings into two internodes and warm with a bottle or glass jar.

Seeds
This method of planting begin in the month of February. Prepare a soil mixture. Seeds are disinfected in a manganese solution and dried. Next you need to perform the following steps:

- Two weeks before planting it is necessary to harden the sprouts. To do this, they are taken out every day for a couple of hours in the fresh air.
Sprouts
- Rinse the tubers and cut them into several pieces. If the tuber is small enough to cut into two parts, larger ones cut into 3-4 parts.
- Fill a small jar or other container with water. The top of the tank should correspond to the size of the portion of the sweet potato, which must be half-dipped in water.
- Part of the tuber is placed cut off into the water, after fixing it with toothpicks from all sides.
- Put the sweet potato in a well-lit place.
- After 14-20 days, the first shoots will appear.

- Place the sprouts in a container of water until the roots appear.
- After 2-3 days, the roots will seem. After that, landing in open ground.
Without sprouts
This method of landing is not suitable for sweet potatoes. This is because if you put the tubers immediately in the ground, the shoots will have to wait a very long time.
