Depart the burlap on B&B timber. Merely take away the twine on the high and unroll the higher portion of the burlap to disclose the basis flare, the place the roots diverge from the principle trunk. Set the tree inside, and place sufficient soil on high to cowl the roots.

Water the tree effectively after planting, and add extra soil on high if it settles under the floor. Assure planting success by overlaying the location with a two to three-inch layer of mulch, like compost or straw. Depart a spot between the mulch and the chestnut’s trunk. 

Rising from Seed

Rising timber from seeds takes a very long time. In order for you chestnuts within the subsequent few years, you’ll need to plant saplings as an alternative of seeds. Develop seeds for a enjoyable experiment, or for those who’d wish to breed blight-resistant cultivars.
