Chaste trees are quite easily propagated from seed. When grown in USDA growing zones 7 through 11, they simply require well-draining soil and a sunny spot in which to grow. After that, chaste trees can be virtually left to their own devices. The seeds are planted in fall, and by spring they explode in showy, fragrant lilac flowers. However, before you plant a chaste tree you should know that it is highly attractive to bees. When choosing a location for your tree, keep in mind that there will be swarms as long as there are flowers. Bees have even been known to sleep on the chaste tree's blossoms. Those with bee-sting allergies should beware.
Stratify the Chaste Tree Seed
Lay a 2-inch layer of moistened peat moss at the bottom of a plastic freezer bag. Lay three chaste tree seeds on top of the peat moss. Cover the seeds with another 2-inch layer of moistened peat moss.
Blow into the freezer bag to provide your chaste tree seed with air. Seal the bag tightly.
Leave the freezer bag in a cool, dark place for four days.
Place the chaste tree seed in the freezer for three weeks.
Move the chaste tree seed to the refrigerator if you are not ready to plant it.
Plant the Chaste Tree Seed
Dig a hole that is 3 feet wide and 3 feet deep.
Mix half of the excavated soil with an equal amount of aged compost.
Refill the hole with the amended soil.
Tamp the soil down with your feet to remove any air pockets.
Plant the chaste tree seed ½ inch beneath the soil.
Water the soil thoroughly, but not so heavily that puddles form. Continue to water your chaste tree seedling regularly until it is established.
