Description

This very fast-growing deciduous tree will grow 40-75' tall and 30-60' wide. It has blue-green or light green leaves with fragrant white flowers in the spring. Thorny branches, hard wood and heavy sucker production make the Black Locust a challenging maintenance project.

Water Saving Tip:

Different areas of your landscape have different water requirements.

Shrubs need much less water than lawns and drip systems should never be scheduled on the same program with lawns.

Establish separate watering schedules for those areas.
