How to grow flowering maple
Overview
Flowering maple (Abutilon pictum) is a fast-growing shrub in the Malvaceae family, valued for its maple-like leaves and pendulous bell flowers in shades of orange, yellow, or red. It provides soft texture and fills gaps between bolder plants, making it a reliable structural element in mixed borders.
Varieties
- Abutilon pictum 'Thompsonii' — Variegated yellow and green leaves, popular in Australian gardens for its striking foliage.
- Abutilon pictum 'Gold Dust' — Orange bell flowers with dark veins, a vigorous grower for temperate and subtropical zones.
Soil Preparation
Prefers slightly acidic to neutral pH (6.0–7.0) in loamy or sandy loam soil. Enrich with well-rotted compost or aged manure before planting. Ensure good drainage; if clay, raise beds or add gypsum.
Growing Guide
Plant in well-drained soil enriched with organic matter, spacing 1–1.5 m apart. Position in dappled shade or morning sun with protection from harsh afternoon rays. Water deeply once a week during dry spells, allowing the topsoil to dry slightly between waterings. Avoid heavy clay or waterlogged sites. Mulch with 5–7 cm of organic mulch to keep roots cool and suppress weeds.
Sowing
Sow seed 3–5 mm deep in seed-raising mix, keep moist at 20–25°C; germination takes 2–4 weeks. Direct sow in spring after frost risk passes, or start in pots for transplanting. Not commonly grown from seed; cuttings are more reliable.
Care
Feed with a balanced slow-release fertiliser (e.g., 10-10-10) in early spring and again in midsummer. Lightly prune after each flowering flush to maintain shape and remove spent blooms. Cut back one-third of old wood in late winter to encourage fresh growth.
Companion Planting
Pair with fuchsia and hydrangea for a cool, shaded border that shares similar moisture and light needs. Avoid planting near aggressive root competitors like bamboo or large eucalypts that may dry out the soil.
Common Pests & Risks
Whitefly, aphids, and scale can appear on new growth and leaf undersides. Control with a strong water blast or horticultural oil; avoid broad-spectrum sprays that harm beneficial insects. Monitor for sooty mould from honeydew and treat the underlying pest.
Troubleshooting
Yellow leaves: often from overwatering or poor drainage; reduce water and check roots. Brown leaf edges: caused by dry air or sun scorch; move to more shade or increase humidity. Leaf drop: sudden cold snap or drought stress; protect from frost and water consistently. Sparse flowering: too much shade; move to brighter spot with morning sun. Sticky leaves: honeydew from aphids or scale; treat with soap spray.
