The profile lets us know that Norway maple seeds are among the cold germs. In concrete terms, this means that only a cold stimulus puts the seed in a good mood to germinate. Here you can find out how this stratification can easily be achieved in the refrigerator at home.
Norway maple seedlings are best raised at home
Harvesting and preparing seeds - Here's how
After flowering in April and May, the winged fruits of the Norway maple soar through the air in late summer and autumn. To get to the seeds hidden inside, proceed as follows:
- Cut off the wings and gently pull apart the bottom end with your fingers
- Pull out the flat seeds
- Soak the seeds in water for 36 to 48 hours
Since the ovary of the characteristic fruits split when ripe, only a little finesse is required for the seed harvest.
Instructions for sowing - How stratification works
Fill the soaked seeds with moist sand or potting soil in a sturdy freezer bag. Tightly closed and twisted into a space-saving sausage, keep the seed bag in the vegetable compartment of the refrigerator at -1 to +3 degrees Celsius. In the freezer, with temperatures of -18 degrees Celsius, it is much too cold for the seeds. This is how it goes on:
- After 6 to 8 weeks, take the seeds out of the fridge
- Fill small pots with potting soil
- Sow seeds, sieve thinly and spray with water
- Cover jars with transparent lids or cling film
- Place in a partially shaded window seat
In the following weeks and months, please check the need for watering regularly. Constant moisture in the substrate has a beneficial effect on further growth. When the first green tips break through the earth, the lid or foil has done its job and is removed. If your Norway maple seedlings have developed 4 to 5 real pairs of leaves above the cotyledons, enrich the irrigation water with diluted liquid fertilizer every 4 weeks.
tips
In the profile of Kugelahorn you can read that Norway maple is his progenitor. In order to multiply an Acer platanoides Globosum, you are still in a losing battle by sowing seeds. In fact, spherical maple is a refinement by the hand of the master gardener, which can neither be propagated generatively with seeds nor using the vegetative method with cuttings.
