      Acer palmatum Dissectum Garnet - The Deep Red Japanese Maple

      Looking to brighten up your garden with striking foliage and graceful form? The Acer palmatum Dissectum Garnet is a beautiful choice. This finely cut Japanese maple offers rich, garnet-coloured leaves that turn bright scarlet in autumn. Compact and slow-growing, it’s perfect for pots, small gardens, or as a feature in mixed borders.

      What Is Acer palmatum Dissectum Garnet?

      Acer palmatum Dissectum Garnet is a medium-sized deciduous shrub with a naturally graceful form. A cultivar of Acer palmatum, or Japanese maple, this variety features deeply lobed, feathery leaves in a warm brownish-red hue throughout spring and summer.

      In autumn, the show intensifies as the foliage turns bright scarlet before falling. The Dissectum Garnet is ideal for a small garden, patio pot, or rock garden where its finely dissected foliage and rich colouring can take centre stage. It grows slowly, typically reaching around 2 metres in height and spread.

      Why Should You Grow Japanese Maple Dissectum Garnet?

      If you’re searching for a perfect focal point in your garden, this ornamental maple tree ticks every box. Its garnet-coloured leaves bring contrast to green planting schemes, and its red and orange tones in autumn are nothing short of dazzling.

      It suits both traditional and modern garden designs and thrives in partial shade or dappled shade, where its leaf colour is at its best. Because it’s compact, it’s ideal for growing in a pot, making it a great addition to courtyards or balconies. Whether you’re designing a peaceful retreat or adding structure to a border, the Dissectum Garnet fits beautifully.

      How Big Does Acer palmatum Dissectum Garnet Grow?

      This small tree or deciduous shrub grows steadily to a height of around 1.5 to 2 metres and a width of approximately the same. It has a domed, weeping shape with gracefully arching branches that enhance its feathery texture.

      Its size makes it manageable even in limited spaces. You can keep it in a pot for several years without needing to transplant it into the ground. With occasional root pruning, it can thrive in containers over the long term. If planted in the soil, allow room for its natural spread so its elegant form remains best left unspoiled.

      Where Should You Plant Acer palmatum Dissectum Garnet?

      Choose a sheltered spot that protects the foliage from wind and scorching midday sun. While it tolerates full sun, excessive exposure can lead to leaf scorch, especially during dry periods.

      Dappled shade or partial shade gives the best colour and helps maintain good soil moisture. Ideal locations include east-facing beds, courtyard gardens, and protected borders. Use it as a focal point among green-leaved shrubs or plant near water for added impact.

      What Soil Is Best for Dissectum Garnet?

      Acer palmatum Dissectum prefers moist, well-drained, slightly acidic soil. Avoid areas with clay or compacted soil that can trap water. When planting, mix ericaceous compost into the soil to improve drainage and match the tree’s pH preferences.

      A layer of mulch around the base helps conserve moisture and suppress weeds. Avoid piling mulch against the trunk. Topdress with compost each spring to support healthy growth and vibrant leaf colour.

      How Should You Plant Acer palmatum Dissectum Garnet in a Pot?

      Growing in a pot or container gives you more control over conditions. Use a large pot with drainage holes and fill it with ericaceous compost. A mix of loam-based and organic matter improves structure and holds just the right amount of water.

      Water well after planting and keep the pot shaded during hot spells. Add a layer of mulch to keep the roots cool. Every few years, refresh the compost and consider occasional root pruning to prevent the plant from becoming pot-bound.

      When and How Should You Prune Dissectum Garnet?

      The shrub is deciduous, so it drops its leaves in autumn and becomes dormant over winter. Avoid heavy pruning, as this variety looks best in its natural form. Prune only to remove dead, damaged, or crossing branches.

      The best time to prune is late winter or early spring, while the tree is dormant. Use clean tools and avoid cutting into thick branches unless necessary for shaping. Light touch maintenance will support its shape while preserving its delicate foliage.

      Does Acer palmatum Dissectum Garnet Flower?

      Yes, it does! In spring, the tree produces small purplish or purple flowers, although they’re subtle and often hidden beneath the foliage. These are followed by red fruits in summer, adding further interest.

      Although not the main attraction, the flowers and red fruits contribute to its seasonal interest. The real glory lies in its foliage, but knowing that red fruits follow flowers makes it even more appealing for year-round beauty.

      What Does Dissectum Garnet Look Like Through the Seasons?

      In spring and summer, the tree is cloaked in brownish-red to garnet-coloured leaves, creating a warm, rich presence in the garden. These deeply dissected leaves give a lacy, feathery effect.

      Come autumn, the colours deepen to brilliant scarlets and shades of orange and red. The leaves that turn bright scarlet in autumn give the tree its spectacular seasonal appeal. This reliable autumn colour is one of the key reasons gardeners choose this Japanese maple.

      How Do You Care for Acer palmatum Dissectum Garnet?

      Water regularly during dry periods, especially in pots. Consistent soil moisture or excessive exposure can affect growth and leaf colour. Avoid overwatering or allowing the roots to sit in soggy soil.

      Use a balanced fertiliser in early spring, but avoid excessive feeding, which may harm the tree. Apply mulch in spring to retain moisture and feed the soil. Keep an eye out for pests, such as aphids, and treat them promptly if necessary.

      Protect the foliage from harsh wind and midday sun to avoid damage to delicate foliage. During the first few years, the tree will establish its root system; therefore, take extra care during extreme weather conditions.

      Where Can You Buy Japanese Maple Acer palmatum Dissectum Garnet?

      You can purchase Japanese Maple (Acer Palmatum) from your local nursery, specialist growers, or online retailers. Always choose a healthy specimen with strong branching and rich leaf colour.

      Plants are usually sold in pots or containers. Look for well-rooted plants that are not pot-bound. Buying from a reputable nursery ensures the plant is well-grown and disease-free, giving it the best start in your garden.

      From Darren’s Patch

      There’s something genuinely magical about the way Acer palmatum Dissectum Garnet catches the light—its feathery leaves shimmer in garnet tones all summer, then explode into scarlet fire in autumn. I’ve grown this variety in a large pot near a shaded seating area where its colour softens the space and provides year-round interest. It asks for very little in return—just shelter from harsh sun and a bit of thoughtful watering during dry spells. What I love most is its natural, weeping shape that never needs fussing over. Whether you’ve got a quiet corner, a Japanese-inspired border, or a spot on the patio, this little tree brings structure and elegance like few others can.
