In addition, the effect of an increase in soil temperature (as a result of increase in air temperature) may be even stronger when accompanied by a decline in soil water content. Therefore, during extreme heat periods soil water content must be kept at an adequate level 1) to provide for plant uptake and 2) to minimize the impact of higher soil temperature caused by higher air temperature.
to obtain the greatest effect. The foliage should be dry to avoid damage to the leaves. This method is not effec- tive on plants such as cabbage or broccoli. It should not be used if foliar diseases or, in many cases, flowers are present. Evaluate the degree of growth regulation pro-vided by brushing before adding a PGR treatment. Also, be aware that the effects of brushing on plant growth
How plants are affected by cold also varies depending upon the type of plant and the above factors. USDA guidelines for plant hardiness are just that, guidelines. The actual hardiness of a plant will fluctuate according to the microclimate, exposure, water and nutrient intake, and the overall health of a plant.
