Colocasia, also known as taro or elephant ear, is a tropical plant that is commonly grown for its edible corms or roots. The corms are rich in carbohydrates and are a staple food in many parts of the world. Harvesting colocasia plants at the right time and using the correct technique is essential for getting the best yield and quality.
Optimal Time for Harvesting Colocasia Plants
The optimal time for harvesting colocasia plants depends on the variety and the purpose for which they are being grown. For eating purposes, it is recommended to harvest colocasia plants when they are around 8-10 months old or when the leaves start to turn yellow. At this stage, the corms are mature and have reached their maximum size.
If you are growing colocasia plants for ornamental purposes, you may want to wait until the leaves have fully developed before harvesting them. This can take up to 12-18 months. However, waiting too long can result in a decrease in corm size and quality.
It is important to note that colocasia plants should not be harvested when they are still young as this can lead to poor yield and lower quality corms.
Harvesting Technique for Colocasia Plants
The technique used for harvesting colocasia plants is as important as the timing. Here are some important tips to keep in mind:
Prepare the soil: Before harvesting, make sure that the soil around the plant is moist. This will make it easier to pull out the corms without damaging them.
Use a digging fork: Use a digging fork to loosen the soil around the plant. Insert the fork into the soil about 6 inches away from the stem and gently lift the plant out of the ground.
Remove excess soil: Once you have lifted the plant out of the ground, gently shake off any excess soil from the corms.
Cut off the stems and leaves: Using a sharp knife or pruning shears, cut off the stems and leaves from the corm.
Cure the corms: After harvesting, it is important to cure the corms for a couple of days in a dry area. This will help to reduce the moisture content and improve their storage life.
