Planting

The ideal times to plant Tamukeyama are in the early fall or spring, when the weather is mild and conditions are most suitable. Planting in the fall allows the maple to establish its roots before winter frost sets in, while spring planting helps it root well before the summer heat arrives.

Choose a spot for your Tamukeyama where the soil drains well and there’s no standing water, ensuring it gets a few hours of direct sunlight daily.

When planting, dig a hole that’s twice as wide as the root ball. Position the maple in the hole, making sure the trunk isn’t buried in soil. You might need to add a bit of soil at the bottom of the hole for elevation. Fill the remaining space with soil and water thoroughly.

If you’re planting during a sunny and hot period, provide some shade for the maple for the first few weeks to help it adjust.

Soil

The ideal soil for Tamukeyama Maple is a well-draining, loose mix rich in organic nutrients. It’s crucial to avoid waterlogged conditions to prevent root rot.

If your garden has clay soil, improve it by mixing in several buckets of quality compost into the planting hole. This will create a nutrient-rich environment that also drains well. For sandy soils, adding compost enhances nutrient content and improves moisture retention.

Ensure the soil’s pH is between 5.7 and 7.0, favoring a slightly acidic condition. If the soil is too alkaline (pH above 7.0), the maple might struggle to absorb essential minerals, leading to yellowing leaves.

To adjust soil acidity, garden stores offer acidifiers like sulfates for lowering pH. Conversely, if your soil is overly acidic (pH below 5.5), applying garden lime can help increase the pH to a more suitable level.

Watering

Water your Tamukeyama Maple whenever the top 2 inches of soil feel dry. For trees that have just been planted, try to keep the soil from drying out more than an inch deep. However, after the tree has been established for a year, you can allow the soil to dry out about 2 inches between waterings.

Overwatering can harm the tree, leading to root rot and yellowing leaves. If you notice signs of root rot, address the overwatering issue immediately and provide some shade to help the maple recover. Once the tree starts showing signs of improvement, you can remove the shade.

Conversely, under-watering can also be detrimental, causing the leaves to curl and brown at the tips or edges. To help retain soil moisture and prevent it from drying out too quickly, applying mulch around the base of the maple is beneficial.

Light

Tamukeyama stands out as one of the most sun-loving Japanese maples, thriving in full sun in nearly all locations. However, in zone 8, it benefits from afternoon shade to prevent sunburn on its leaves. Unlike Tamukeyama, most Japanese maples generally prefer partial shade regardless of the climate.

For optimal growth, position Tamukeyama where it can bask in 6 to 8 hours of direct morning sunlight, followed by full or partial shade for the remainder of the day.

Avoid placing this variety in completely shaded areas. In full shade, its leaves tend to display a greenish-red hue, and the tree may produce fewer leaves and branches.

Fertilizer

The ideal fertilizer for Tamukeyama is a balanced, slow-release type that nourishes the plant evenly over time. It’s best to apply this once annually in early spring. Steering clear of fertilization in early summer is crucial, as it can prompt new leaves to grow quickly and turn green, losing the desired red hue.

Over-fertilizing should be avoided to prevent the plant from becoming overwhelmed by excessive growth or suffering root damage due to salt accumulation. Additionally, it’s important to skip winter fertilization to avoid encouraging the growth of young shoots, which are likely to be harmed by frost.

Problems

Tamukeyama leaves can sometimes fall prey to various fungal infections, leading to the appearance of brown or black spots and even small holes on the foliage.

To prevent such issues, ensure there is ample air circulation around the maple; avoid planting it too close to buildings or other vegetation. If you do spot any discolored patches on the leaves, treating the maple with a copper-based fungicide can help.

Additionally, pests like insects or mites may also affect Tamukeyama, indicated by curling or yellowing leaves. Should you observe any unusual changes in the leaves, inspect them closely for pests. Upon detection, spraying the affected areas with a water-based horticultural oil solution can offer effective control.

Japanese Maple Tamukeyama vs Japanese Maple Garnet

Tamukeyama Japanese Maple vs Garnet Japanese Maple

The primary distinction between the Japanese Maple varieties Tamukeyama and Garnet lies in their leaf coloration. Tamukeyama showcases deep reddish-burgundy leaves that gradually shift to a red-brown hue. In contrast, Garnet starts the season with vibrant crimson-red leaves that later darken.

Another difference is in their size; Garnet tends to be slightly larger, reaching heights of 7-8 feet and widths of up to 12 feet, while Tamukeyama typically grows to 6 feet and occasionally up to 7 feet tall, with a spread of about 10 feet.

Inaba Shidare Japanese Maple vs Tamukeyama Japanese Maple

Tamukeyama Japanese Maple vs Inaba Shidare Japanese Maple

The Inaba Shidare Japanese Maple stands out from the Tamukeyama Japanese Maple primarily due to its foliage. Inaba Shidare features bright red leaves that may fade a bit during the summer, only to have their vibrant color intensify again in the fall. On the other hand, Tamukeyama boasts burgundy leaves that can sometimes appear almost purple.

Moreover, Inaba Shidare is slightly more resilient to heat, making it suitable for growing in zone 9. While Tamukeyama thrives in zone 8, it might find the conditions in zone 9 less favorable.

Red Dragon Japanese Maple vs Tamukeyama Japanese Maple

Tamukeyama Japanese Maple vs Red Dragon Japanese Maple

The key difference between the Red Dragon and Tamukeyama Japanese Maples lies in their color retention. Tamukeyama starts the spring with a vivid burgundy hue that tends to fade over the summer and shifts to a brownish tone. In contrast, Red Dragon’s reddish-burgundy leaves maintain their color throughout most of the summer and into the fall.

Another distinction is in their shapes and sizes. Red Dragon has a more rounded, globular form, reaching dimensions of 8-10 feet in both height and width. Tamukeyama, conversely, displays an umbrella-like shape, typically spreading to 10 feet wide and standing 7 feet tall.

Japanese Maple Bloodgood vs Tamukeyama Japanese Maple

Tamukeyama Japanese Maple vs Bloodgood Japanese Maple

The distinctiveness between the Japanese Maple Bloodgood and Tamukeyama Japanese Maple primarily lies in their foliage. Bloodgood features larger, dark red leaves split into 5-7 lobes without further dissections, presenting a simpler, bold look. Tamukeyama, however, has more intricately cut lobes, giving it a finer, more decorative appearance with its smaller, burgundy-colored leaves.

Another notable difference is their size and growth habit. Bloodgood can reach up to 25 feet in both height and width, making it significantly larger than Tamukeyama, which typically grows to about 7 feet tall and 10 feet wide.

Additionally, while Tamukeyama boasts a weeping form, adding a graceful, downward sweep to its branches, Bloodgood grows in a more upright manner, with branches extending vertically or horizontally, but not in a weeping fashion.

I bought this tree not really knowing to much about it going on my 2 year old and is growing rapidly! Love this tree but I'm afraid I made a mistake by planting only a foot away from house footing. It doing so well and thriving I'm afraid to transplant and move it!! If anybody sees this or went through same issue hopefully you can respond. Can you train the plants that it will grow out& away from house?

It's great to hear that you love your tree and that it's thriving! While it's not ideal to have a tree planted so close to your house footing, there are a few things you can do to help manage its growth and minimize any potential issues:

Pruning: Regular pruning can help shape the tree and direct its growth away from the house. By selectively removing branches that grow towards the house and encouraging growth in other directions, you can train the tree to grow away from the structure. Supportive structures: Installing stakes or guides near the tree can help guide its growth away from the house. By attaching the tree's branches to these structures, you can gently direct its growth and prevent it from leaning towards the house. Root barriers: Consider installing a root barrier between the tree and your house. Root barriers are typically made of rigid materials and are buried in the ground vertically to prevent the tree's roots from encroaching on the foundation. This can help minimize any potential damage to the house. Regular monitoring: Keep a close eye on the tree's growth and its proximity to your house. If you notice the tree starting to pose a significant risk or causing damage, it might be necessary to consider transplanting it to a more suitable location.
