In general, Japanese maples have shallow roots, so they appreciate a cool, evenly moist but well-draining site. Consistent moisture is key. A light covering of mulch can help to conserve moisture, but keep the mulch away from the trunk.
A newly planted Japanese maple should be watered thoroughly over the first few days to eliminate air pockets and settle the soil. Make sure that the area is well-draining, so that the roots do not sit in water (the plants do not like wet 鈥渇eet鈥). After that, they’ll need to be watered regularly. Sandy or loamy soils may need water about every 2 to 4 days, while clay soils may require less frequency. Once trees become established, give the tree about 1.5 to 2.0 inches of water about every week or so, or when the soil becomes dry about 3 inches below the surface. During hot/dry spells, water slowly but deeply so that it reaches the top 12 inches of soil. When the leaves drop in fall, water once per month until the ground freezes.
