Q. How can I keep my Tamukeyama Maple red longer in the summer months as it spends half the day in the shade?
Also what type of fertilizer do you recommend for Japanese maples? And when and how often should I apply it?
The key to maintaining the deep red color of Acer palmatum var. dissectum 'Tamukeyama' is the right balance of sun and shade. It needs to be protected from scorching with partial shade in the afternoon and mulch to retain moisture. Without five or six hours of good direct however, it simply will not have that beautiful deep color all summer.
As long as you plant it in moist, organically rich, slightly acidic, well-drained soils and refresh the soil with compost annually, you will not need to fertilize this plant.
