How to Plant Acorn Seeds
Planting acorn seeds is a fun and environmentally worthwhile project that costs practically nothing. Acorns propagate quickly in the right soil with plenty of water and drainage. You can gather acorns off the ground for free by exploring almost any stretch of forest in the fall. Plant the acorns in April and you'll have seedlings 6 inches tall within a month. Your oak trees will be ready for planting outdoors within 2 months. Does this Spark an idea?

Tips & Warnings
Don't wait too late to gather fall acorns or insects and squirrels will beat you to them. Look for acorns from October to mid-November. Plant only whole, uncracked acorns with no visible signs of damage. You can begin growing acorns at any time of year, but the seedlings should not be planted outdoors until mid- to late May after the final threat of frost has passed.
