Heat stress is a serious problem for trees and other plants when the temperatures are high. Plants that are already compromised due to low nutrition in the soil or that have disease around their roots will not fare well and can die from heat stress.
All plants require a given amount of micronutrients, water and sunlight to properly perform photosynthesis, the process that creates the sugars (called brix) that the plants survive on.
When the temperature is high, several conditions can manifest themselves in the plant's ecosphere. If there is too much rain, fungi can take over and cause diseases to hinder plant growth. If there too little rain, the plant can't create sugars that are needed for growth, and so they are stunted. As a result, plants under these conditions will either not produce fruits or flowers, or they may produce fruits and flowers that are blighted.
Signs of heat stress are irregular yellowing and dropping of leaves that may have rust-colored spots or bumps. The specific causes of these symptoms include nitrogen deficiency (browning from the leaf tip inward) and potassium deficiency (browning along the outer edges). Brown spots and bumps are frequently attributed to a bacterial condition coming out from the soil.
Treatment of heat stress needs to be proactive to be most beneficial. Treating plants with a biostimulant containing sugar, such as MaxGrow
, and a program of regular watering is the best way to prevent or treat heat stress.
