Plums trees are simple to plant from seeds and are an ideal addition to a landscape or garden. The main problem with growing plum trees is keeping animals away from digging up the planted seeds. There are remedies for this though, and you can enjoy wild plums throughout the year.
Collect plum seeds from a plum. Wash them thoroughly in the sink. Let them dry for about two weeks on a paper towel in a dry, cool area.
Find a well-drained area to plant the tree that is in full sun. The ideal soil for growing a plum tree is loamy, and sandy or clay soil is the least ideal.
Use a shovel or till to loosen the soil about 12 inches. Insert the plum seed about 4 inches deep and cover with soil. Use a sprinkler to water the seeds for about 10 minutes in the morning and 10 minutes in the evening for the first four days. After that, water every other day for 10 minutes in the morning. You want to keep the soil moist but not in puddles.
Create a barrier around the plum seed so squirrels cannot get to them and dig them up. Use chicken wire and wooden stakes to build a 1-foot-by-1-foot dome around the seed. The point is just to protect it from animals digging up the seeds.
