Acer Palmatum diss 'Ornatum' 80cm Pot 250cm Height Outdoor Tree

Acer palmatum dissectum ‘Ornatum’ is a classic lace-leaf Japanese maple, admired for its finely cut foliage, graceful cascading shape, and ever-changing colour through the seasons. One of the older and most reliable cultivars, ‘Ornatum’ brings an elegant, architectural quality to gardens.

🌿 Key Features:

• Foliage: Deeply dissected, lace-like leaves emerge bronze-red in spring, mature to rich reddish-green or bronze-green in summer, then blaze with brilliant scarlet to crimson hues in autumn. The fine texture creates a delicate, airy look.

• Habit: A small, slow-growing, mounding tree with gracefully arching branches. It typically reaches 1.5–2.5 metres high with a wider spread (up to 3–4 metres), forming a beautiful dome.

• Bark: Young branches have a slight reddish tone, adding subtle winter interest.

This variety is perfect near ponds, in rock gardens, or as a specimen in lawns and borders. Its cascading habit also makes it excellent for showing off on raised banks or walls, where its branches can drape naturally.

🌱 Detailed Care Guide for Acer palmatum dissectum ‘Ornatum’

📍 Position & Light

• Prefers partial shade or dappled sunlight.

• A little morning sun enhances leaf colour, but protect from hot afternoon sun which can scorch the fine leaves.

• Shelter from strong winds is essential to prevent leaf damage.

🌬️ Shelter

• Plant in a protected spot, avoiding exposed, windy sites.

• Also protect from late frosts, which can damage new growth.

💧 Watering

• Likes consistently moist but well-drained soil.

• Avoid allowing the soil to dry out completely, particularly in pots or during hot weather.

• Annual mulching helps maintain moisture and keeps the root zone cool.

🪴 Soil

• Prefers slightly acidic to neutral, fertile, humus-rich soil that drains freely.

• Avoid heavy clay or alkaline soils. If necessary, improve soil with organic matter or plant in raised beds or containers with ericaceous compost.

🍽️ Feeding

• Feed lightly in spring with a balanced slow-release fertiliser or an acer-specific feed.

• Avoid high-nitrogen feeds, which can produce soft growth more prone to wind and frost.

✂️ Pruning & Maintenance

• Minimal pruning needed.

• Remove any dead, damaged or crossing branches in late autumn or winter while dormant.

• Light shaping can also be done then. Avoid heavy pruning, which can spoil its natural cascading shape.

🪲 Pests & Problems

• Generally pest-free.

• May occasionally suffer from aphids on new shoots.

• Leaf scorch (brown edges or tips) is usually due to drought, hot sun, or strong winds.

🚰 Container Growing

• Excellent choice for a large pot, ideal for patios or small gardens.

• Use ericaceous compost mixed with grit for drainage, and raise pots on feet to ensure water runs out freely.

• Keep well watered in summer and protect container roots from freezing in winter by wrapping or moving to a sheltered spot.
