How to Grow

From seed

When you are planting fresh plum seeds or pits, first remove the pit and wash in lukewarm water with a soft scrub brush to remove any pulp.

The seed needs a chilling off period at temperatures of between 33-41 F (1-5 C) before it will germinate, about 10-12 weeks.

This is called the stratification process and there are two methods to accomplish it.

The first method is to wrap the pit in a moist paper towel inside a plastic bag and then place it in the refrigerator.

Leave it there for six to eight weeks, keeping an eye on it in case it sprouts earlier.

Natural germination is also a method of stratification wherein the plum pit goes directly in the ground during the fall or winter.

It’s a good idea to add some organic matter, but no fertilizer, into the hole, about a month before planting the pit.

When planting the fresh plum seeds, they should be 8cm deep in the soil.

Mark where you have planted the pit so you can find it in the spring.

Leave the plum pit outside through the winter months and watch for any sprouting; thereafter, keep the new plant moist and watch it grow.

If you have cold stratified the seed in the refrigerator, once it has sprouted, remove it and plant the plum pit in a container with well-draining soil composed of one part vermiculite and one part potting soil, about 5 cm deep.

Situate the pot in a cool, bright area and keep moist but not too wet.

From Plant

After all danger of frost has passed, select a new location in the garden for your new plum tree with at least six hours of direct sunlight.

Prepare the soil by digging a hole 30cm deep, removing any rock or debris.

Mix compost into the soil.

Plant the new plum from a pit to its original depth and tamp the soil around the plant.

Water and keep evenly moist.

Collect seed

Remove the pit and wash in lukewarm water with a soft scrub brush to remove any pulp.

The seed needs a chilling off period at temperatures of between 33-41 F (1-5 C) before it will germinate, about 10-12 weeks.

This is called the stratification process and there are two methods to accomplish it.

The first method is to wrap the pit in a moist paper towel inside a plastic bag and then place it in the refrigerator.

Leave it there for six to eight weeks, keeping an eye on it in case it sprouts earlier.

The second is to plant directly in the ground.
