I bought this on a whim in about a one-gallon pot for about ten bucks, at the biggest of America's big box stores, no less. Something just gave me a hunch and I must say I was right. With zero pruning, after two years it has become a gorgeous specimen, with vertical leader (main trunk) growth, and horizontal side branch growth, with just a tad of cascading. The leaves retain their color here in hot, rainy Louisiana. And I've been keeping it in way too small of a pot and I've barely fertilized it. For those who are curious, it gets full sun until about 2 PM and shade after that. I predict it could probably take a few more hours of full sun.

I love my JM tree. It has grown so much in just three years. I purchased a very small tree only because I did not have the budget for the $200.00 I really want. But it grows so well, and I just have not had the heart to really prune it. I have pruned earlier in the spring last year but very minimal amount. I really think it needs some shaping.
Question: when is the best time to prune, and what suggestions are out there about shaping and how much to prune. Besides my beautiful fringe tree, it is my favorite tree ever. When the fringe is in bloom, I have a hard time deciding. The JM is favored the rest of the time, and I want to be totally sure I know what I am doing.

I've been really impressed with the way this holds its color in the shade. The foliage looks good all season and I've been surprised with how fast it has grown for a Japanese maple. It's definitely one of my favorite weeping varieties and I've been able to find it cheaper then a lot of the other good ones.

I've been reading your articles on the Japanese Maples and found a lot of good, useable info. Thanks! I just got my first one this summer- a Inaba Shidare. The trunk is just over 1/2" and quite tall. I have it in a container on our patio. It's in the south east corner of an L-shape area of the house for protection. The tree is protected from the south and the west which helps with the sun. (I live in northern Indiana.)

The tips of the leaves are turning brown- what causes this? Is it still maybe getting too much sun?

Another question: Since they are more vulnerable when young, should I put it in the garage for the winter? If I do this, what about light, water, etc.?

I love this tree and can't wait till it gets large enough to cas... read more

This is a very popular Dissectum Group Japanese maple. The leaves are among the largest of any Dissectum. They emerge rich purple-red and hold the excellent colour all season, finally turning brilliant red in autumn. The leaves are coarser than most Dissectums and the stems more sturdy. It is also known as 'Select Red', 'Red Select' and 'Holland Select'.
