Collect the seed pods from a sycamore tree in the fall when they turn brown. Allow them to dry for up to two weeks until they break open easily, and extract the seeds from the seed pods. Remove the hairs from the sycamore seeds by rubbing them against a wire screen.

Fill a medium planting pot with a general-purpose potting soil. Place the sycamore seeds on top of the soil, separating them by about 2 inches. Cover the seeds with 1/8 inch of soil. Keep the pots at room temperature and water the soil regularly to keep it from drying out. The seeds should germinate in about 2 weeks.

Transplant the sycamore saplings to the permanent planting site when they are at least 6 inches tall. Water the saplings regularly to keep the soil moist. The soil should have good drainage, although a sycamore tree can tolerate soil with poor drainage. The tree should not require special maintenance after the first growing season outside.
