In respect to this, should I prune my smoke bush?

The rule for pruning deciduous flowering plants states that if it flowers after June 1, like the smoke bush, you need to prune in early spring. Smoke tree pruning can also be done in late winter if you wish to rejuvenate the plant and cut it all the way to the ground.

Likewise, how do you take care of a smoke tree? Young plants should be watered deeply and regularly, but once established, smoke bush has good resistance to drought. Mulch the base of the shrubs with wood chips or bark mulch to keep weeds away and soil moist.

Consequently, how fast do smoke bushes grow?

Growth Rate The purple smoke tree grows moderately fast. The Arbor Day Foundation defines this as vertical growth of 13 to 24 inches per year.

Do smoke trees lose their leaves?

Smoke trees lose their leaves in the winter but in the spring their new growth and fluffy clusters of flowers attract admirers. They can be cut back in late winter like any shrub. The result is lush growth in the spring, keeping the plant to 6 or 8 feet.

Why does my smoke bush not bloom?

When buds form and then fail to bloom, there can be several different reasons, one possibility is there is not enough sun when the buds are ready to bloom. For instance, if the tree is planted near larger trees that leaf out, then there may be too much shade for the plant to receive the sunlight it needs to bloom.

How tall does a purple smoke tree get?

This slow growing, open-crown, round, small tree eventually reaches to 12 to 15 feet tall (occasionally 20) and 10 to 12 feet wide (Fig. 1). The large panicles of wispy purple-colored flowers produced in spring and early summer give the effect of a cloud of smoke.

How do I prune a tree?

Pruning begins at planting time
  1. Prune to shape young trees, but don't cut back the leader.
  2. Remove crossing branches and branches that grow back towards the center of the tree.
  3. As young trees grow, remove lower branches gradually to raise the crown, and remove branches that are too closely spaced on the trunk.

Why is my purple smoke bush green?

A tough plant, Cotinus Coggygria performs best in full sun, in average, medium, well-drained soils. Purple-leaved varieties planted in shade may see their leaves turn green. Smoketree is not fussy about soils provided they are not soggy or wet. Good drainage is essential.

How big do smoke trees grow?

Size. The smoketree is native to parts of Southern Europe and Central China. When left unpruned, it grows as a vase-shaped, multistemmed tree or large shrub, generally reaching a height of 10 to 15 feet. As a smoketree matures, its branches tend to spread out, giving the tree an open, wide shape.
