Johin Japanese Maple

Acer 'Johin'

Overview

The Johin Japanese Maple (Acer 'Johin') is a one-of-a-kind variety with incredible foliage that's sure to turn heads. It stands out from the crowd with its bright yellow-green colored leaves, framed by a deep green margin. Mature trees usually have a beautiful, gnarled trunk, making it an ideal choice for bonsai enthusiasts. In the spring, its delicate white flowers add an extra layer of beauty, before the dramatic autumn hues of red, yellow and orange set in. It's an easy-to-care-for, slow-growing tree that becomes even more stunning with age. Perfect for home gardens, patio or courtyard spaces, it's no wonder the Johin Japanese Maple is so popular.

Care Guide

💧

Watering

Johin Japanese Maple should be watered about every 5-7 days with about 1 gallon of water on each occasion. Water should be applied slowly and evenly so that the soil is thoroughly soaked. Generally, it is better to water your plant deeply only once instead of a little bit every day.

☀️

Light

The Johin Japanese Maple needs full sun in the morning and afternoon, as well as some afternoon shade. It should receive at least 6 hours of direct sunlight each day, with a minimum of 4 hours in the morning and 2 to 4 hours in the afternoon. Avoid exposing it to intense midday sun as it is more susceptible to sunburn.

🌡️

Temperature

Hardiness zone 6–6.

✂️

Pruning

Johin Japanese maples should be pruned in early spring, before new growth appears. Pruning should be light, removing no more than 10-15% of the tree at each pruning session. Pay particular attention to crossing or exposed branches, and those that are crossing the center of the tree. Heavy pruning should be avoided, as this encourages weak and leggy growth. Additionally, take care not to prune away any flower buds or new shoots that are forming.
