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

These days, conservation efforts are making headway in producing a blight-resistant American chestnut.
Sure, they’re! They develop shortly in gardens with full solar.
Some species can, although most of them require the presence of one other tree for environment friendly cross-pollination.
