A tuliptree is fed if needed and checked for winter damage in spring, watered deeply through summer dry spells, kept moist into fall, and pruned while dormant in late winter. Steady summer moisture matters most, because drought is what most often turns its leaves yellow and drops them early.

Why does a tuliptree need extra attention in summer?

Because it is a fast growing, very tall tree with large leaves that lose water quickly. In dry spells it sheds yellowed inner leaves early to save moisture, and drought stressed trees can also draw more aphids and scale insects.

What does a tuliptree need in spring?

A check for winter damage and, if last year's growth was weak, feeding once the soil warms. Cracked limbs and split bark are noted, and young trees are watered as new leaves expand.

The TreeHelp Premium Fertilizer, chosen by tree type in a 3.3 lb bag that treats one mature tree, is applied in spring for a tree that grew slowly the year before.

What does a tuliptree need in summer?

Deep watering across the root zone in dry spells and a fresh layer of mulch. Soil is moistened 12 to 24 inches down beyond the canopy edge, and mulch 2 to 3 inches deep, kept off the trunk, holds that moisture.

What does a tuliptree need in fall and winter?

Watering until leaf drop in a dry fall, and pruning in late winter. Dead, crossing, or storm damaged branches are cut while the tree is dormant, before spring growth begins, and the tree is checked after winter storms.

No. Despite the name yellow poplar, it belongs to the magnolia family, and its tulip shaped flowers show the connection.

Why are tuliptree leaves sticky in summer?

Usually honeydew from aphids or tuliptree scale. TreeHelp's guide to getting rid of sooty mold on tree leaves covers the black mold that often grows on it.

When does a tuliptree bloom?

In late spring. The greenish yellow and orange flowers open high in the crown, often after a tree reaches several years of age.
