The plum is a drupe whose seed is inside the stone that is found in the core of the fruit. You can harvest seeds from most plum varieties you find on the market and subject them to a process called "layering". Once germinated, you can transfer them to the garden or into a pot.
Steps
Part 1 of 3: Collect the Seed
Step 1. Buy ripe plums at the market
Choose those that are grown in your area or in a similar climate, to make sure they withstand the environmental conditions in which you live; it is better to avoid early varieties because it is difficult for the seeds to develop into plants with similar characteristics.
Step 2. Eat the pulp
Choose the tastiest fruit and plant the seed, because generally the "child" tree tends to keep the "maternal" traits.
Step 3. Remove all of the pulp until the pit looks completely clean
Step 4. Display it on the windowsill for a few days
The seed inside dries and shrinks a little, facilitating the conservation process; in addition, the shell breaks more easily when it is dry.
Step 5. Get a little nutcracker
Place the core horizontally between the two ends of the tool and gently break it apart.
Be careful not to press too hard; a crushed seed produces no plants
Step 6. Extract the seed which has an almond-like appearance
This is the element you need to bury in order for it to germinate.
Step 7. Fill a glass of water
Drop the seed on us; if it sinks, you can try to make it sprout; if not, try another pit until you find a suitable seed.
Part 2 of 3: Germinating the Seed
Step 1. Leave it to soak overnight in the glass of water
For this operation choose water at room temperature.
Step 2. Fill a plastic bag or airtight jar 2/3 full with compost-rich soil
Moisten the earth but don't overdo it.
Step 3. Place the seeds or seed in the compost and seal the container
Shake it so that the seeds penetrate deep into the loose soil.
Step 4. Set the refrigerator temperature to about 4 ° C
Put the container back inside to begin the layering process. This cold germination technique allows the seeds to develop roots, so they can be transplanted into the garden and become trees.
Part 3 of 3: Planting the Seeds
Step 1. Choose the final location for the plum trees
It is advisable to plant at least two trees, so that they can pollinate each other and bear fruit.
Step 2. Opt for a frost-free area
It must be slightly sheltered, a surface that you can mulch and cover to avoid frost that would kill the seedlings; they must also be exposed in full sun.
Step 3. Get plenty of well-draining potting soil and compost before burying trees
Adding the earth allows the water to drain better.
Step 4. Consider planting plums in large pots and relocating them later if you are unsure of the best location
Be sure to use deep vessels with drainage holes.
Step 5. Remove the seeds from the jar or bag when they have developed white, healthy roots
Be careful not to break them during the transfer.
Step 6. Dig a small hole a few inches deeper than the roots
Create a small mound of soil in the center and place the seed on it, taking care to distribute the root system all around.
Step 7. Cover the seed with more potting soil
Space future trees about 6-8m from each other.
Step 8. Water the earth and protect it
Wet the soil thoroughly before it dries completely; plums should start fruiting in 3-5 years.
