I've had this little tree for three years, it did not like being in a container! He dropped all his leaves the first year, I thought it was dead but it came back next year alive and well, but still was not growing. Now it's in the grown and it's thriving, it gets at least four hours of after afternoon sun, this type of red maple likes more sun.

I've Had this compact - Micro tree for about 3 years now. Its great looking in the spring But My biggest problem comes late summer all the tips - edges of the leaves become crispy brown. It's in a 18" square concrete container. Any suggestions ? to prevent this. Summers are hot here So I moved it last yr so it would get only moring sun, but it did the same thing again.

This was today's purchase at our favorite nursery and the owner is very dedicated to his work. The plant is healthy, no browning or curling of leaves. Beautiful condition and will thrive here, per the owner of the nursery, Jack Weisskott of Ornamental Plantings, Southold, NY.

This Dissectum Group maple has red leaves with a hint of orange. It is very vigorous and will reach to 4m, or may be lower if grafted low. Like most Dissectums, it has a pendulous, mounding form. the leaves are among the largest of any Dissectum. It is a very popular selection that arose originally in the Netherlands.
