Q.Three wks ago I purchased a black pussywillow bush/small tree. It stands about 3.5-4 ft. It was FULL of blooms coming on & so full
& green. We put in in the ground right away, w/ a little bit of Miracle grow potting soil. It has since turned & the leaves are t urning brown! We have kept it watered properly also. PLEASE HELP!! !
This plant likes loamy, moist, rich soil. It wants to be kept wet and will tolerate poorly-drained soil, but it is best if the soil is well-drained.
These plants love moisture. You will need to ensure they have plenty of water and are not subjected to drought conditions. In the first couple weeks; maintain a daily watering schedule. After this water them once or twice a week if there is no natural rainfall through their first season.
Review the care in the article below.

You may also want to contact the greenhouse that you purchased the plant from. Most reputable garden centers will help you with care and will replace a new planting if it dies within the first year.
