PAGE A2. WHITBY FR2EE PRESS, OUTDOOR LIVING APRIL 13P 1988 PlatIocatio depends on regional differences PlaengreeioS ByRICKPECMAN O.G.S. GARDEN GALLERY Thlckfon Road North Moving from one part of the coun- try to another, particularly from north to south or vice versa, you may have been surprised at how dif- ferent gardening is between the two regions. Regional differences play an im- portant role in the location of the plants in your garden. Azaleas, which can be planted in almost full sun in Whitby need plenty of protec- tion from the elements in Hilton Head Island, South arolina. The reason for such differences is that the intensity of the sun i- creases thre doser you are to the equator. Add to that basic fact the multitude of climatic influences -fog, clouds, rain wind, and others and you quick.ly realize that banket statements concerning the type of exposure to give a plant are difficuit tomake. Many gardeners nave heard of "iplant hardiness," or "hardiness zone," but are a bit confused as to the relevance of these terms to the plants they have or are about to pur- chase. Plant hardiness is a term used when describing the ability of a plant to survive in the location it is intended for, or planted in, usually stated as; "Rhododendrons are hardy in Whitby, depending on thre species chosel. " Hardiness zone, on thre other hand, denotes a certain area to which plants can be assigned as being har- dy (will survive) under most cir- cumstances. A handy guide is the Canadian Plant Hardiness Zone map, which is available at Most local garden centres in Durham. broken down by numbers. Whitby, for example, falîs in between zones 6A and 5B. Before purchasing a plant, make sure that its hardiness rating is 6A or lower. A plant which is rated a 7 may be able to survive in Niagara Falls but may struggle or not survive at ail in Whitby. A plant with a rating. lower than 6A will mean that it will survive furtirer north than Whitby, so it should have no problem surviving here, if it is planted correctly and in its desired location. The preceding paragrapir brings to light thre three major factors in- volved in plant survivability: 1. The plant ishardy. 2. Thre plant is planted properly. 3. Tire plant is put in' its desired location ( 'eg. shade/sun, wet/dry, windy/nonwindy ... ) Once thre basic rules are learned.
