Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the shrub from the container, gently tease the roots and cut away any circled or tangled roots.
Position in hole and backfill with soil, gently firming down. Form a raised or doughnut shaped ring of soil around the outer edge of the plant's root zone. This helps keep water where it's needed. Always water in well after planting to settle the soil around the roots and keep the soil moist for several weeks while the new plant establishes.
Mulch around the base with organic mulch like bark chips, sugarcane or pea straw, keeping it away from the trunk.
Water deeply, once or twice a week, depending on weather conditions.
Cumquats can grow up to 5 m tall or around 2.5 m for dwarf grafted trees, which are ideal for growing in smaller spaces and also pots. They’re hardy trees and will grow well in cool climates as well as warm areas. They need a spot with well-drained soil that receives at least 6 hours of sunshine a day.
Early to mid autumn is an ideal time to plant a new cumquat tree.
Keep the new tree well watered, particularly during its first summer. Cumquats are heavy feeders and require lots of nutrients to support all the foliage, flowers and developing fruit. While trees are flowering, growing new foliage or carrying fruit, feed every 8 weeks with Yates Thrive® Natural Citrus & Fruit Organic Based Pelletised Plant Food. It contains a special combination of more than 50% natural ingredients, boosted with fast acting fertilisers. It encourages healthy green leaf growth and is high in flower and fruit promoting potassium.
