Walnut is a deciduous tree from the walnut family. This plant can be found in Korea, China and Japan, in Central Asia and in the south of the Balkans. Walnut prefers moist neutral or slightly alkaline soils and is not frost-resistant. This plant reproduces mainly by seeds. To preserve the characteristics of the variety, propagation by grafting is used.
It is necessary
- - nuts;
- - sawdust;
- - sand.
Instructions
Step 1
Like any seeds enclosed in a dense shell, walnut seeds need to be stratified. To provide the nuts with suitable conditions for germination, they are planted in the ground in the fall. For spring planting, seeds should be kept in cold and high humidity conditions.
Step 2
For planting, use fresh nuts from this year's harvest. The longer they have been stored, the lower their germination will be. If you have the opportunity to harvest the seeds yourself, choose ripe nuts that easily fall out of the pericarp pod and leave them in the sun for a day or two. You can dry the seeds in the shade.
Step 3
If you plan to plant nuts in the fall, choose an area of slightly acidic or slightly alkaline soil. Acidic soil should be limed before sowing. The groundwater level at the site should be constant, but not high. Dig up the ground and make a groove eight centimeters deep in it.
Step 4
Place the nuts in the groove on the edge, about forty centimeters apart. The distance between the rows must be at least one meter. Sprinkle earth over the nuts. In areas with little snowy winters, crops should be covered with grass or sawdust with a layer of ten to twenty centimeters.
Step 5
In the spring, when the nuts begin to sprout, remove some of the sawdust, leaving a five centimeter layer. Walnut seeds germinate unevenly, shoots may appear even after a year.
Step 6
Before planting in spring, the nuts are kept for a period of one to three months in wet sand or sawdust. Seeds with shells, the thickness of which is less than a millimeter, are best soaked in water, nuts with thick skin are stratified according to all the rules.
Step 7
Before putting nuts in sawdust or sand, soak them for two to three days in room temperature water, which will have to be changed every day. Place the soaked seeds in a container with damp sand or sawdust on the edge, sprinkle with a substrate and put them in a room with a temperature of three to seven degrees. Containers of nuts should be checked once a month and the substrate should be moistened if necessary.
Step 8
Nuts with thin shells are stored at a temperature of one to five degrees in a dry place, and a month before planting they are soaked in water at room temperature. When the shell flaps open, the seeds are spread on the edge in a container with wet sawdust and germinated at a temperature of about twenty-five degrees.
Step 9
Plant the sprouted nuts in the ground after the spring frost ends.
