The Skinny on Skinny Trees – Columnar / Fastigiate Trees
Columnar or fastigiated trees make great candidates for landscape areas where space is restricted such as in parkway strips, between the sidewalk and driveway, or near the corner of a building. Many of these trees can also be used as a privacy screen. Columnar trees are also recommended for parking lots where outward branching can get in the way of vehicles. Be sure to check the salt tolerance factor of the tree before planting in a parking lot.
Winter burn happens when plants dry out during the winter. Even during the colder months, evergreens continue to lose water vapor through their needles, which are modified leaves. The plant attempts to replace the water by pulling it from the roots. However, when the ground is frozen, the roots cannot absorb enough water to supply it to the dry needles. If the weather turns breezy, warm and sunny while the ground is still frozen (like today, in the Midwest), evaporation from the needles increases and water cannot be replaced fast enough. Discolored, brown or burnt -looking foliage may start to appear when this happens. In fact, winter burn indicators typically develop during warm weather in late winter and early spring.
Winter damage is often misdiagnosed as a disease or as damage from excessively cold temperatures. The damage which starts at the tips, is brown or rust-colored and generally on the side of the plant facing the sun and/or the side exposed to the wind, where the rate of evaporation from the needles or leaves is greatest.
NOAA says that December through February – for meteorological record-keeping purposes, winter is defined as those three months in the Northern Hemisphere – was 1.42 degrees Fahrenheit above the 20th-century average for all land and ocean areas. This tops the previous warmest winter of 2007 by 0.05 degrees Fahrenheit. Global temperature records are available for the period 1880-2015.
I’m going to be curious if we’ll give 2015 a run for its money for 2016 on temps.
Water lawns during the early morning when temperatures and wind speed are the lowest. This reduces evaporation and waste. Watering in the evening can leave leaves wet all night, promoting disease problems. Better yet. DON’T WATER THE LAWN AT ALL!!! It doesn’t die, it goes dormant.
Start a compost pile or scrape food into the trash instead of running your garbage disposal*, which requires a lot of water to work properly. Use the compost to improve the quality and water holding capacity of your soil. *Save yourself from having the plumber out also!!
Do not leave sprinklers or hoses unattended. Your garden hose can pour out 600 gallons of water or more in only a few hours, so don’t leave the sprinkler running all day. Use a kitchen timer to remind yourself to turn it off.
