Probably not, but just in case visit this page: Japanese Maple Diseases. If you really feel the need to fertilize a Japanese maple, use something organic, something low in nitrogen. It’s much safer to mix rotted cow manure (bagged) into the hole as you plant your tree and not fertilize at all. How much have you fertilized your tree? Japanese maples don’t like and cannot use a great deal of nitrogen fertilizer. If you have the tree planted too deep and there is three or four inches of soil on the stem of the tree it is planted too deeply and should be raised immediately.Ĥ. There should not be more than one inch of soil up on the stem of the tree. Make sure the root ball is covered with soil so you actually have a slight mound over the root ball so excess amounts of water are shed away from the tree. Is your tree planted too deep? Even if you have really good soil that drains well, the top of the root ball should be at least one inch above grade. This is only true if you have clay soil that does not drain well.ģ. The root ball needs to be covered with soil, but you should raise the bed so at least half of the root ball is above the grade of your bed. If you have heavy, wet, clay soil that does not drain well you should plant your tree with the entire root ball buried in the ground. When you water the water that you apply should drain away within an hour or so and not linger around the root zone of your plant. They don’t like standing water around their roots for very long at all. How wet are the roots and or the soil around the roots? Japanese maples do not like wet feet. But the soil should not stay soaking wet all the time.Įxclusive: Free Plans to Build Your Own Simple Homemade Plant Propagation SystemĢ. The soil should be moist and cool to the touch, not powdery dry. Trees that have only been planted a few weeks or even a few months should be watered once or twice weekly, but it’s important to check to see how moist the roots are before you water. Have you been watering the tree as needed. If your tree has only been planted for a short time there are four things that I’d look for immediately.ġ. Now if all of the leaves on your Japanese maple are turning brown and falling off, you have a serious problem. It’s certainly not something I get concerned about. It is my experience that this drying of the edges of the leaves is just something that happens and seems to happen to most of my dissectum Japanese maples every year starting around late July. Does this mean the roots are dry and need more water? That depends on how much rain you’ve had in your area prior to this happening. It’s a lot like holding a blow dryer to the leaves. But often times, late in the summer, especially with the dissectum varieties, the edges of the leaves turn brown just from the extreme heat and the wind blowing across the leaves. Usually brown spots appear because the leaves got wet when the sun was out and that can cause a small burn on a leaf with a droplet of water on the leaf.īrown edges can be a sign of a tree that de-hydrated. Brown spots on the leaves during the growing season can be caused from a number of different things, and for the most part none them are of serious concern. In order to avoid either of these problems make sure that the tree is planted on a well-drained site with good air circulation.Usually leaves turning brown around the edges, brown spots on the leaves, or maybe leaves falling from the tree during the growing season. Verticillium wilt can affect entire limbs of the tree. This cultivar lends itself well to a Japanese themed garden.īacterial canker may burn some of the ends of the branches. In hot climates it should be protected from the afternoon sun in order to reduce the chances of leaf scorching. Occasionally these fruit will sprout.Ĭrimson Queen grows on a wide array of soil types in either full sun or partial shade. They emerge red in the spring (late April) but soon take on their purplish red summer color before turning crimson in September.Īs with other Japanese maples this variant sets small flowers in the spring which latter give rise to winged, 2-lobed samaras which ripen in late summer to early fall. It bears palmate leaves with 7-9 lobes, which are deeply cut and dissected. In the fall the leaves take on a brilliant crimson color.Īs with other dissected cultivars, Crimson Queen grows into a small tree with an eventual height of 6’-10’ and an equal width in a mounding form with cascading branches. Description Crimson Queen Japanese maple is one of the more well known of the mound forming dissected types with its dark red summer foliage that holds up very well under full sun conditions. ![]()
