It is not difficult to grow a walnut tree in a pot yourself. All you need is fresh walnuts paired with a bit of luck. You should also make sure from the start that you have enough space in your garden for a gigantic walnut tree, because the plant gets very large over the years. Learn how easy it is to get a walnut to grow and thrive!Walnuts can be grown well in pots
Cultivation in pots explained step by step
- For a strong seedling you need five to six fresh walnuts (not from the supermarket!).
- Remove the green peel.
- Do the swim test to sort out dead nuts (healthy nuts sink to the bottom, unfit ones float to the top).
- Take a flower pot and fill it with damp leaves.
- Place the nuts on the foliage.
- Put some garden soil on the nuts.
- Close the pot tightly with chicken wire (14.99€) (keeps rodents away).
- Dig the pot into the ground in your garden (to protect against frost damage).
- The shells open between late March and early April. As a result, root and shoot appear.
- Transplant the walnuts into a fresh flower pot with garden soil. But now insert the nuts close to the surface.
- Place the pot in a bright, cool place until after the ice saints to protect the walnut seeds from frost. Temperatures of two to ten degrees are ideal.
- Keep the potting soil slightly moist.
- Place the seedlings in your desired place in the garden after the following ice saints.
- Water the seedlings regularly for the first few weeks after this measure, especially on warm, dry days.
- In the first year, the plants grow about 25 to 30 centimeters in height.
- From the seedlings, determine the two or three strongest seedlings. Pull all others carefully out of the ground.
- Next spring you select the most beautiful walnut baby. Cut off the weaker plants below the root neck (in the ground). This will prevent these specimens from growing further. Caution: Don't pull any more here, so as not to damage the roots of the chosen pupil.
- In the third or fourth year it is time for the first cut.
In order to accelerate growth and get the first harvest faster, grafting makes sense.
