Live Oak Germination Time

Germination Time

• The average germination time for acorns planted under optimal growth conditions is about one week, cites the Mississippi State University Extension. Keep the growing medium moist through germination time. Do not over-water as the acorn will rot before germination. After seedlings have emerged, remove the weaker seedlings and allow the stronger ones to get established before moving them to a permanent site in the landscape.

Collecting Acorns

• The best time to collect acorns for propagation is during fall -- any time from October to December. Often acorns start to germinate while still attached to trees. It is best to pick ripe acorns from the tree before they fall to the ground as these become prone to infestation from weevils. Ripeness is indicated by a brown color rather than the yellow of the unripe ones. To test maturity, separate the acorn from the cup; it should come apart clean without leaving tissue residue.

Planting Tips

• Fresh acorns planted immediately after collection germinate readily without any pre-planting treatment such as scarification or stratification. Check the viability of acorns by placing them in a large pan of water. The ones that float to the top are not fully developed or are damaged. Fill a medium-size pot with equal amount of potting soil and topsoil from the garden. Plant several acorns in each pot, inserting to a depth of three times the length of the acorn.

Cultural Requirements

• Plant live oak in areas of full to partial sun. The tree prefers a well-drained soil and adapts well to acidic or alkaline ground. Established trees are tolerant of drought and sandy soil. Live oak trees are also adapted to coastal conditions. Tree growth is optimal in regions with warm, humid weather. Live oaks are hardy in USDA zones 8 to 11.
