Abstract

Citrus growers frequently have asked when should trees lost in a citrus grove be replaced, i.e., every year, every three years, etc. or should no trees be replaced until the entire block has become non-productive (or non-profitable). To answer these questions, a discounted cash budget model was developed to compare several tree replacement scenarios which included no tree loss and tree loss with and without tree replacement. These scenarios were compared with a hypothetical zero tree loss situation based on data obtained from a long-term 'Valencia' field trial on Carrizo citrange rootstock planted at 116 trees per acre (25' × 15'). The analyses indicated resetting a citrus grove will result in positive returns over no resetting. If a block in a grove is experiencing a high annual tree loss with a rapid decline in yield and returns, replanting the entire block should be evaluated before resetting a grove.
