Pruning encourages new growth of trees, so late pruning is recommended for deciduous trees and grape vines. If you cannot get into these spaces, you may have to hire a contractor. The occurrence of a radiation frost is rare during cloudy or foggy conditions because the net radiation losses are reduced. Identify the cause and correct it before adding insulation. Consequently, black plastic is less effective for frost protection. Typical problem areas include poor flashing at a hip, valley or the chimney and ice dam leaks. INA bacteria concentrations were reduced by to fold following three weekly applications of bactericide i.
The location of vents is as important as their number and type. After the first experiment, growers began to prune the tree skirts to allow more sunlight to the orchard floor under the trees. Ensure that the scaffold is erected and dismantled only by a competent person under strict supervision of a competent supervisor. Melt water runs down the roof until it meets the overhang. However, even during non-cloudy periods, the San Joaquin Valley is prone to fog formation. A simple method to determine the best soil water management to use for frost protection is to measure the minimum soil surface temperature when the soil is exposed to different management. A wide variety of methods are used to cover the plants and to anchor the plastic.

Insulate on top of the existing roof see Section 5. If the loose fill is deeper than the joists, build insulation framework a crib around the attic hatch so that it can be filled to the edge see Figure This effect is called efflorescence and occurs mainly in concrete tiles. Soil heat conduction and storage depends on the bulk density, heat capacity, thermal conductivity and ultimately the diffusivity. A hatch should be large enough to allow you to bring in materials. If the replacement roof covering was significantly heavier then there is the risk that the roof structure may collapse if it is not designed to carry the extra weight. Because they are inexpensive and easy to construct, fruit-frost shelters are often used for nighttime temperature measurements during frost events Figure 6.
The dead growths will weather off and disappear quite quickly. Seal and insulate up to party walls in attached housing see Section 5. Otherwise, the plastic can float on the canopy and rise up as the crops grow, but disease problems are more likely. Consequently, good plant nutrition and sanitary status favours acclimatization and resistance to freezing Alden and Hermann, ; Bagdonas, Georg and Gerber, White plastic provides some protection and it is sometimes used for nursery stock. This process may be suitable for some attics, but do not proceed without approval from your building inspector, and then only use a certified spray foam contractor who is familiar with the process.
