Avoid fields that have very high nematode populations. Bedding Plants are established in rows on flat land. During the cultivation process, ridges are formed down the rows of plants. Ridges provide a place for storage organ formation, improve drainage and facilitate harvesting. Cover Crops Cover crops are beneficial in crop rotation programs, but are not recommended immediately after tannia and taro production.
Cultivation is needed after harvest to prevent feral plant establishment.
Weed Management Tannia and taro are long-season crops. Control of weeds during roduction can be difficult. Early season competition of weeds is extremely critical and a major emphasis on control should be made during this period. Growers must plan a total program that integrates mechanical and cultural methods of weed control with the use of herbicides. Cultivation is an effective way to manage weeds early in the season.
