Garden beds dry out very quickly in windy weather, including those beds protected by mulch. The reason is that plants maintain some humidity around them by drawing water from the soil and releasing it through tiny holes in their leaves, a process known as transpiration. As strong wind constantly removes the moisture, more and more water is drawn from the soil in an effort to maintain humidity. As soil dries out, cells collapse in the soft tissues of plants causing drooping of plants and possibly death of small seedlings.
A way to avoid this problem in windy weather is to use plastic soft drink and juice bottles to funnel water directly to the root area of susceptible plants. This is a quick and very efficient way to hand water during water restrictions or windy weather. Limp tomato seedlings will freshen up in about 10 minutes after watering by this method.
Simply cut off the base of each container, remove the lids and bury the necks of the containers about 8 cm deep near outer edge of the foliage of plants. Large shrubs may require several containers. Pour water into the container until it begins to drain slowly – an indication that you have dampened the soil in the root area.
For plants that are generally sensitive to wind, filtering the wind rather than blocking it provides better protection for delicate plants. A solid cover or wall causes wind to whirl around on both sides of the screen, but a lattice trellis or product called ‘Windbreak’ on the side of the prevailing wind reduces the impact of the wind, as indicated below.
