How to Grow Citrangequat

× Citrofortunella

Perennial

Citrangequat is one of the hardiest citrus hybrids, tolerating brief frosts to -10C. Plant in full sun against a sheltered south-facing wall, or grow in a large container that can be moved under cover in winter. Feed fortnightly with citrus fertiliser during the growing season. Fruit ripens in autumn and winter — pick when fully orange. Prune lightly after harvest to maintain shape.

Care Requirements

☀️ Light

Full sun essential

Needs at least 6 hours of direct sun daily. A south-facing sheltered position is ideal in cooler climates.

🌿 Spacing

3m apart in ground

Space 3m apart for in-ground planting. Can be grown in containers of at least 50cm diameter for flexibility.

💧 Watering

Regular but not waterlogged

Water regularly during the growing season, especially container plants. Reduce in winter. Never let roots sit in water — good drainage is critical.

🌱 Fertilizing

Citrus feed fortnightly in season

Apply citrus fertiliser every 2 weeks from April to August. Reduce to monthly in winter. Avoid high-nitrogen feeds which promote leaf growth over fruit.

Growing Tips

Wall training pays off

A south-facing wall provides reflected heat and frost protection. Essential in zones where temperatures regularly drop below -5C.

Consider container growing

Container growing allows you to move the tree under cover during severe cold snaps. Use a pot at least 50cm diameter with good drainage.

Harvest timing matters

Fruit left on the tree too long becomes pithy. Pick when skin is fully orange and gives slightly to pressure.

Pests & Diseases

Pest Scale Insects

Identification: Small brown or white bumps on stems and leaf undersides. Leaves may become sticky with honeydew.

Organic treatment:
  • Wipe off with a damp cloth or cotton bud dipped in methylated spirit
  • Spray with fatty acid-based insecticide
  • Introduce parasitic wasps in greenhouses
Chemical treatment:
  • Apply systemic insecticide containing acetamiprid
Pest Citrus Leaf Miner

Identification: Silvery trails visible within young leaves, causing them to curl and distort.

Organic treatment:
  • Remove and destroy affected leaves
  • Hang pheromone traps to monitor populations
Chemical treatment:
  • Spray with spinosad-based product when new growth appears
Disease Citrus Canker

Symptoms: Raised brown lesions with yellow halos on leaves, stems, and fruit.

Treatment: Remove and destroy affected material. Improve air circulation.

Prevention: Avoid overhead watering. Disinfect pruning tools between cuts.

Disease Root Rot

Symptoms: Yellowing leaves, wilting despite moist soil, dark mushy roots.

Treatment: Improve drainage immediately. Repot container plants in fresh compost. Reduce watering.

Prevention: Ensure excellent drainage. Never let pots sit in saucers of water.
