How to grow coral aloe
Overview
Coral aloe (Aloe striata) is a stemless, clump-forming succulent grown for its broad, blue-green leaves edged in pink and its coral-red winter flower spikes. It thrives in dry, well-drained positions and is valued as a gap-filler in low-water borders.
Soil Preparation
Prefers neutral to slightly acidic pH (6.0–7.5) in sandy or gravelly soil. Improve drainage by mixing in 30% coarse sand or pumice. Avoid heavy clay or water-retentive mixes.
Growing Guide
Position in part shade, especially afternoon relief in hot climates. Plant in free-draining sandy or gravelly soil; add 30% coarse sand or pumice if clay. Space rosettes 60–80 cm apart. Water deeply only when soil is dry to 5 cm; never let sit wet. Mulch with pebbles, not organic matter.
Care
Feed once in early spring with a balanced slow-release fertiliser (e.g., 8-8-8) at half rate. Remove spent flower stalks and any dead or damaged leaves to maintain shape. No regular pruning needed.
Companion Planting
Pair with other low-water succulents like Echeveria, Sedum, or Agave. Avoid heavy feeders or moisture-loving plants such as ferns or impatiens that would encourage rot. Also avoid planting near lawn irrigation.
Common Pests & Risks
Scale insects and mealybug can appear on leaf undersides and in leaf axils. Treat with horticultural oil or spot-apply rubbing alcohol. Overhead watering can encourage fungal spots; keep leaves dry.
Troubleshooting
Yellowing leaves: overwatering or poor drainage; reduce water and check roots. Brown leaf tips: too much direct sun or salt buildup; move to part shade. Soft, mushy base: root rot from wet soil; cut away rot and repot in dry mix. White cottony patches: mealybug infestation; treat with oil or alcohol.
