Some Spring Days in Iowa By the way, I always use wire hairpins to hold down creeping rootstocks of every kind; it keeps them from springing up and drying before the rootlets have a chance to grasp the soil. The Garden, You, and I A rootstock can affect the tree it supports in various ways. Northern Nut Growers Association Report of the Proceedings at the Forty-Second Annual Meeting Urbana, Illinois, August 28, 29 and 30, 1951 In certain plants there is an underground stem or rootstock, which grows perennially, and each year produces a plant from a bud at its end.

The Manual of the Botany of the Northern United States Including the District East of the Mississippi and North of North Carolina and Tennessee 2012-04-12T02:00:30.140Z The plant seldom sets seed in this vicinity, but seems to depend rather upon its tuber-like rootstocks in which the leaves lie curled all through the winter. Some Spring Days in Iowa The Christmas fern, with its glistening leaves of holly green, has a stout, creeping rootstock, which must be firmly secured, a few stones being added temporarily to the hairpins to give weight. The Garden, You, and I Sometimes the rootstock will force to the top too much growth, which is likely to bring about unfruitfulness. Northern Nut Growers Association Report of the Proceedings at the Forty-Second Annual Meeting Urbana, Illinois, August 28, 29 and 30, 1951 The plant spreads rapidly by running rootstocks, and ripens seed in abundance.
