How to Grow Polish Sour Morello Cherry Fruit Seeds

Polish sour Morello Cherry trees or Wisniak Tree as the Polish refer to this abundant fruiting cherry red stone fruit.

Prunus cerasus austera L ‘lutowka’ is a slow growing often multi-stemmed tall tree attaining just 7-12 feet high and 7 feet wide. Small Fruiting trees are highly sort after particularly where space is limited and whilst a number of fruiting cherry tree varieties exist.

P. ‘lutowka’ is the hardiest and best performing example of a fruiting cherry I have had the pleasure to work alongside.

Polish Sour Cherry Flowering in my yard

Introduced to the US in the 1990s this is the most popular sour cherry ground originally from Europe it is an increasingly popular Cherry for liquor and cordials.

Hardy in zones 3-8 I have a super maturing example of this small urban fruit tree. Freely self pollinating and quickly produces large crimson red fruit within 2 to 5 years of sowing.

Heavy fruiting Polish sour cherries popular as a cordial in Poland.

The parent tree growing in my own back yard was brought over to N.E coast of USA in early 1990’s by my husbands Polish Babcia (Grandmother). Originally smuggled into the country from far eastern Poland almost 30 years later and it still supplies the local Polish neighborhood with fresh sour morello cherries.

Today I am offering you a chance to grow a few trees yourself! Ten easy to grow from seed first chill the hard seed in the freezer for a few weeks in a small ziplock bag.

Adding some abrasive chips of horticultural grit to the ziplock bag will speed up the germination process by helping to breakdown the hard nut like stone outer layer and allow it to absorb moisture from the surrounding substrate.

This cold period will improve germination and imitate a hard winter, breaking dormancy and encouraging the seed shell to soften allowing the emerging seed embryo to break free. Leaving the seeds for at least a few weeks will improve germination times and rates, removing the seeds from the freezer simple sow an inch deep along with the grit in a soil based seed compost, tray or square pots.

Germination will take anything from 30-365 days depending on growing conditions. Once germinated grow on seedlings, keeping them moist, free from drafts, keep plants growing well-supported to encourage an upright stem or main trunk. A growing tree will require a larger container size every 6 months for the first few seasons. Once approx 6ft tall plant out in the trees final location, free from overhead power cables and buildings.
