How do you keep a Japanese maple red?

It's caused by high pH in your soil, which in turn causes an iron deficiency. If the pH is above about 7.5-7.7, the iron gets tied up chemically and is not available to the plant, even though there still could be iron present in the soil. The higher the pH, the worse the condition gets.

Japanese maples are truly a four-season plant: In the dead of winter, the graceful and delicate branches standing out in contrast to snow or the featureless grey sky. In the spring, the bright vibrant green of the new leaves emerging and the gradual, day by day growth and emergence of the ephermal flowers. In summer, the shadow play of leaves and the branches, depth and coolness of shade. And, perhaps most notable, the brilliant display of fall. The beauty of each season is in its impermanence, the daily change and inevitable shift into the next phase.
What is the abscission layer of a plant?
As the daylight decreases, the trees and shrubs ready themselves for the cold and dark of winter. Plants get ready to do this by forming a layer of cells at the base of the leaf stem, sometimes referred to as a separation layer or abscission layer. Abscission is defined as a natural detachment of parts of a plant.
What is the term for the detachment of parts of a plant?
Abscission is defined as a natural detachment of parts of a plant. During the growing season the chlorophyll in the leaves, responsible for both photosynthesis and the green color, is continually replenished. Once the cells start forming the corky layer the chlorophyll is no longer replaced.

Graceful branches, arching upward in the case of the upright varieties, or cascading downward in the horizontal varieties are accented by a delicate lacework of fine leaves. The tree is always encouraged to exemplify the natural habit, never forced to agree with imposed geometry. The act of pruning maples can be likened to gem-cutting: We don’t make the precious stone; the Gardener’s task is to find and display its best features.

What Turns a Japanese Maple Green?
'Red Dragon' is only one of a range of beautiful Japanese maple varieties featuring deeply cut leaves in vivid colors, and a characteristic these trees often share is that their roots come from a different tree. Growers select the tree to supply the roots and lowest portion of the trunk according to its ease of propagation, drought or disease resistance or a similar beneficial trait. This part of the tree is called the rootstock. The grower then attaches the decorative tree to the rootstock in a process known as grafting.
How do Japanese maples produce leaves?
As the tree grows, the rootstock may produce shoots from the trunk below the graft union or send up suckers from its root. Unless these stems from the rootstock are removed, eventually the growth from the green-leaved rootstock dominates the red-leaved, decorative tree above it, and the tree mostly produces green leaves. To rectify the problem, remove the rootstock growth and prune the decorative section of the tree to encourage stronger growth.

What color do leaves turn in autumn?
Exactly which colors predominate in autumn leaves depends on the tree species and the local weather. Temperature and light influence the intensity and duration of autumn color. Rainy, overcast days may cause the chlorophyll to degrade more quickly, thus increasing the intensity of the yellow colors and orange colors. Low temperatures above freezing favor production of the red-pigmented anthocyanins. Early frosts degrade the reds. Japanese Maples stay small in size and are low maintenance trees. Perfect for adding year-round color! Weather is the primary factor for why your maple tree leaves are not turning red in fall.

How do trees start?
Many tree cultivars originally start as a genetic accident or an aberration that appeared on an otherwise normal tree. If that aberration was appealing, horticulturists may then seek to propagate that "mistake" and create a whole line of trees that duplicate that unusual characteristic. Many trees with variegated leaves or unique leaf colors or unusual fruits began their lives as "sports," or genetic mistakes that were then deliberately cultivated through different methods, including grafting new branches onto hardy rootstocks. In the case of red or purple Japanese maples, branches from trees with desired colors are grafted onto hardier rootstocks that are more durable in the landscape.
How to make a maple tree with unusual colors?

What happens when a tree sprouts from the ground?
When this happens, the new branches that sprout (" sucker ") up from the ground will have the genetic makeup of the original rootstock —which will be green, rather than red or purple.
