Loved for its deep red leaves with purple tints, the Japanese maple is ideal for adding interest and colour to any garden. Beyond its stunning shape and colour, this compact, slow-growing tree is perfect for smaller outdoor spaces, as it will not quickly outgrow your garden and is simple to maintain. It doesn’t require full sunlight and can be grown in a container or directly in the ground.
However, as summer approaches and temperatures begin to rise, the gardening experts at Herter Nursery recommend three “essential” tasks to keep your Japanese maple “looking beautiful all season long”.
1. Pruning
According to the pros, spring is “the best time to lightly prune” your Japanese maple. Focus on removing dead or weak branches to improve airflow, as well as crossing or crowded branches that could cause damage as they grow. Avoid heavy pruning in early spring, as it can stress the tree; instead, wait until late spring to shape it as needed.
2. Mulching
A fresh layer of mulch helps retain moisture, regulate temperature, and prevent weeds from growing near the base. By conserving moisture and keeping roots cool, mulching plays a vital role in supporting the overall well-being of your tree. Apply a two to three inch layer around the base, but avoid piling mulch against the trunk, as this can lead to rot. The best materials are shredded bark, wood chips, and pine needles. Over time, organic mulch breaks down, so check regularly and replenish to maintain the recommended depth.
3. Watering
Spring weather can be unpredictable, so monitor soil moisture closely. Japanese maples prefer moist, but not soggy, soil. The experts warn: “Overwatering can harm the roots, while too little water can cause stress.” Check soil moisture by inserting your finger one to two inches into the soil, and water deeply once or twice a week, depending on rainfall. Watering in the morning helps roots absorb moisture before the heat of the day.
By following these three tasks, you can ensure your Japanese maple remains healthy and vibrant throughout the summer season.
