All About the Rangpur Lime Tree.
The Rangpur lime tree grows a citrus fruit that is believed to be a hybrid between the mandarin orange and the lemon. It is named after the Rangpur region in Bangladesh, where it was originally cultivated.
These fruits resemble small mandarin oranges, but have a sour flavor that is more like a lime. The flavor is tinged with distinct floral notes, which makes it very unique and memorable. Rangpur lime juice and zest can be used for making cocktails, marmalades, and dressings.
Here are some key points to consider when growing a Semi-Dwarf Rangpur Lime Tree.
Climate and Location: Rangpur lime is a subtropical citrus variety and is best suited for regions USDA hardiness zones 9-11. They are frost sensitive trees, and if you live in an area that gets freezing temperatures, they should be grown in a container and brought inside for the winter.
Soil: Rangpur lime trees in pots thrive in a chunky, well-draining soil mix like our DIY Primo Potting Mix.
Sun: Plant or place your pot in a sunny location where your Rangpur Lime tree will receive at least 6-8 hours of direct sunlight per day.
For in-ground planting, dig a hole in a prepared/amended space that is as deep as the root ball and twice as wide. Place the tree in the hole, making sure the top of the root ball is level with the soil surface. Be careful not to bury the crown of the roots, but instead keep them right at the surface of the soil. Water thoroughly after planting. The prepared space should be 3x the size of the root ball and as deep as you can dig. This amended soil should be well-draining and chunky, allowing for root growth.
For container planting, choose a starter pot that is 10-14” wide with lots of drainage holes. Good drainage is crucial for the health of your citrus tree. Use a chunky, well-draining soil mix like our DIY Primo Potting Mix.
When planting your tree, gently remove as much of the old dirt as possible without disturbing the larger root structure in the center and its surrounding roots. Plant your tree by filling ¼ of your pot with soil mix and add your tree, with or without its stake, in the center. Carefully fill the space around your tree with soil mix. Make sure there are no air pockets, and the tree can stand in the middle. Leave just the top of the roots, or the crown, above the soil line. Water your tree deeply and thoroughly.
Watering: Rangpur lime trees require regular, consistent watering, especially during dry spells. Keep the soil moist but not waterlogged. It's important to water at the base of the tree, aiming at the soil to avoid wetting the foliage, as citrus trees are susceptible to fungal diseases.
Fertilizing: Use a balanced citrus fertilizer or a fertilizer specifically formulated for citrus trees. We recommend Romeo Fertilizer and G&B Organics Citrus & Fruit Tree Fertilizer. Apply it according to the manufacturer's instructions, typically in the spring and late summer.
Pruning: The best time to prune your citrus tree is in the early spring. Prune the tree to remove dead or diseased branches and to shape the canopy for better air circulation and sunlight penetration. Regular pruning can help improve fruit production and reduce the risk of pests and diseases. Click here to read about Pruning Your Citrus Trees.
Pests and Diseases: Keep an eye out for common citrus pests like aphids, scale insects, and citrus leaf miners. Treat infestations promptly. Protect your tree from diseases such as citrus canker and citrus greening (HLB) by practicing good hygiene and following local recommendations for disease management.
Harvesting: Rangpur limes are typically ready for harvest when they turn bright orange in color. In tropical areas, the fruit may stay green. This is becase citrus needs a period of cool weather to change color. The limes can be harvested throughout the year. Use pruners or scissors to cut the fruit from the tree, as pulling the fruit may damage the branches.
Growing a Rangpur lime tree may require some protection from cold temperatures in cooler regions. In colder zones, consider planting your Rangpur lime tree in a large container that can be moved indoors during the winter months to protect it from frost.
