Replanting a citrus grove can be an exciting prospect, but it’s not as simple as swapping trees. New cultivars, for example, may require a different setup. Here are some aspects to consider before jumping in:
First steps: Newly released cultivars and rootstocks as wells as the Citrus Research and Field Trial programs are refreshing the available options. You may want to discuss some choices to consider before purchasing tress, so contact your local Extension agent for guidance. They can help assess site suitability, market potential and regulatory considerations. Begin a simple discussion about the factors to consider, connect with experts and gather technical information.
Rebuild, recycle, adjust: Check your infrastructure before replanting. Irrigation systems, soil amendments and pest management strategies may need to be planned and adjusted.
Understand the biology: Each stage of tree growth has different root structures, nutrient needs and pest vulnerabilities. What works for one may not work for another, so get informed before making a decision.
Soil and water compatibility: Conduct soil tests and water-quality assessments, even if you had them done before for your last crop. New roots, for example, are more sensitive to salinity or pH than established roots.
Irrigation needs: Crops require different irrigation volumes and schedules throughout the season. Make adjustments according to the time of day, season and prevailing weather conditions. This can save you a lot of money and time, as well as reducing potential fungal disease issues.
Nutrition plans: Nutrition is more than fertilizer application. Fertilizer grades and types (granular, controlled-release, etc.), frequency, application method and timing all need to be considered. Your Extension agent will be happy to work with you to develop a stage-specific plan for nutrient management. Root establishment is crucial and can shape the plant’s growth and success.
