Safeguarding Citrus From Heat Stress

Josh McGill Tip of the Week, Weather

By Amir Rezazadeh Rising temperatures and climate change challenges of recent years have brought a significant threat to citrus trees. Heat stress, caused by prolonged exposure to high temperatures, poses a severe risk to citrus trees. Excessive soil evaporation, inconsistent rainfall and poor soil water-holding capacity can make trees even more sensitive to heat. High temperatures result in shortened internodes, …

Considerations for High-Density Citrus Plantings

Josh McGill planting, Tip of the Week

By Amir Rezazadeh Among all the factors that will affect the productivity and profitability of a citrus grove, choosing the optimal tree spacing is crucial. Florida citrus growers are planting trees at significantly higher densities than in the past. Due to negative impacts on plant health following the emergence of huanglongbing (HLB or citrus greening) in Florida, canopy growth substantially …

Pruning Pointers for Cold-Hardy Citrus

Cover Crop Considerations for Citrus

Josh McGill Cover Crops

By Amir Rezazadeh Cover crops protect the soil from sunlight, wind and heavy rain, which enhances soil microbial populations and improves soil structure, water infiltration and root penetration. A reduction in soil crusting, erosion, runoff and nutrient leaching are additional advantages. Through improved nitrogen cycling and nutrient retention, cover crops increase soil fertility. ORGANIC MATTER SOURCECover crops offer an inexpensive …

Hurricane Season Is Here. Are You Prepared?
