Larvae, which are infinitesimally small (OK, slightly larger than that but not much) at that point, do minor damage in the miner phase, and in fact their burrows are difficult to spot. When they first hatch in mid-June, leafcutter larvae burrow into maple leaves and begin “mining” tissue between the upper and lower epidermis, or skin, in a circular pattern. The maple leafcutter (Paraclemensia acerifoliella) moth, a tiny insect that is rarely noticed, is a native pest with a steel-blue body and a bright orange head, although I could probably say anything once I’ve told you it’s hard to see. ![]() It sounds like another joke, but it’s true. What’s actually going on is that the maples are moth-eaten. In addition to holey-ness, leaves also exhibit circular brown patches, and by September some had turned entirely brown and fallen off. Beginning in August, near-perfect circles of leaf tissue have gone missing from sugar maples, and from other trees to a lesser extent, as if swarms of Hole-Punch Fairies had gone berserk. Only a joker would argue that plant breeders have secretly crossed our beloved sugar maples with Swiss cheese, but given the way this year’s maple leaves are riddled with mysterious holes, it almost seems a plausible explanation. Bradford Walker, Creative Commons, some rights reserved If you see any dead, dying, or damaged branches, prune them in the winter when your tree is dormant.Damage from maple leafcutter larvae (Paraclemensia acerifoliella). Pruningīloodgood Japanese maple trees do not require regular pruning, but they do respond well to pruning if you decide to do so. Use a slow-release, well-balanced organic fertilizer with an NPK value of 10-10-10. You can fertilize your Bloodgood Japanese maple tree in early spring, before the new growth. After that, you can water just once a week or whenever the top 1-2 inches feel dry. Wateringįor the first few weeks after planting, you should water your Bloodgood Japanese maple tree every two to three days. ![]() Because Bloodgood Japanese maple trees prefer moist soil, it’s recommended to add a 2-3 inch layer of organic mulch over the soil once per summer for moisture retention. They thrive in soil that is well-draining, moist, and slightly acidic. Soilīloodgood Japanese maple trees are adaptable to a wide range of soils-clay, loam, sand, and more. However, shadier planting sites will lead to more robust and vivid foliage colors. They can also grow in full sun, which is six hours or greater. Sun and shadeīloodgood Japanese maple trees prefer to grow in partial shade, or about four hours of direct, unfiltered sunlight per day. Be careful not to let the mulch touch the tree’s trunk.īloodgood Japanese maple trees are low-maintenance, adaptable to a wide variety of soil types and able to grow in a range of light conditions. Finish by adding a 2-3 inch layer of natural mulch, like bark or wood chips, around the tree in a three-foot radius.Gently tease the roots apart with your hand or a small spade, then place the root ball in the center of the hole. ![]() Your Bloodgood Japanese maple should be about one inch above the level of the surrounding soil. Dig a hole three times the width of the root ball and roughly the same depth.Clear away any weeds, turfgrass, and debris.Partial shade is preferable, since it will result in richer foliage colors. Choose a plantain site that receives partial shade to full sun.The ideal times to plant Bloodgood Japanese maple trees are in spring and fall. Bloodgood Japanese maple trees grow in Zones 5-8, across most of the country except for the extreme hot and cold regions. USDA Hardiness Zones indicate the regions where plants can grow based on minimum winter temperatures.
