ABSTRACT

The reader should be aware that these are average figures only and may vary considerably among winters. In addition, because specific site mesoclimates and aspects can influence temperature considerably, the designation of a specific zone is considered accurate to +/– one zone. Therefore, the south slope of a hill may experience zone 4 winter conditions while the north slope of the same hill may experience zone 3 winter conditions. In addition, the hardiness zone does not speak to variations in soil pH, salinity, texture, and water-holding capacity, atmospheric relative humidity, wind, etc. Therefore, plants adapted to the same zone may vary widely in other requirements necessary for adequate growth. hardwood cuttings: These are about 17 to 23 centimeters (7-9 inches) long and taken from dormant, current year’s or one-year-old wood. As with the selection of softwood cuttings, take hardwood cuttings from healthy, vigorous, but not overly vigorous shoots or suckers. Make the cut at the base of the shoot with a sharp knife, as cutting shears sometimes crush the wood and reduce rooting. If frozen wood is collected let it thaw in the sun before bringing it to the propagating room.
