bush out

[The Grizzly] has a heavy head, a rather wolflike face, with full cheek tufts of fur bushing out well up to the ears,

Removing the shoots on the side of the plant will encourage it to grow upward instead of bushing out.

The Stalking-Hedge should be two or three Yards long, and about a Yard and an half high, and made in small Wands, and bushed out in the manner of a true Hedge, with certain Supports or Stakes, to bear it up from falling whilst you take your aim to Shoot. And this is to be carried before you for your Shelter from the Fowl.
