Dear Helen: When we returned to live in our lovely Saanich after an absence of 18 years, we were unaware that the deer population around Cedar Hill had expanded greatly 鈥� until potted pansies that聽we placed on the patio were reduced to stalks. Lavender, rosemary and marigolds have been left untouched, but apart from the marigolds there is little colour. I鈥檇 appreciate a list of plants that don鈥檛 appeal to deer.
G.L.
The first truth to acknowledge is that, if hungry and/or thirsty enough, deer will eat just about anything. Only a fence is sure to bar entry to them. A see-through fence needs to be 240 cm (eight feet) high.
For added summer colour, calendula and dahlia plants are not usually attractive to deer. Dahlias flower over a very long period and are available in a broad range of plant heights and flower colours.
As you have discovered, aromatic herbs like rosemary, lavender and thyme are safe, as are many aromatic plants, such as most other culinary herbs.
More annual flowers that deer are not commonly attracted to are zinnia, salvia, nasturtium, sweet alyssum, cosmos and sunflower.
Among deer-resistant perennials are peony, phlox, sedum, campanula, hardy geranium, and shasta daisy. For shrubs, consider California lilac (Ceanothus), boxwood, rock rose (Cistus), smoke bush, daphne, heathers, skimmia, pieris and choisya (Mexican orange).
Many spring-flowering hardy bulbs are not appealing to deer, daffodils and grape hyacinth among them. In the fall you鈥檒l see them marked as聽deer resistant on packages in聽garden centres.
Lists of 鈥渄eer-proof鈥� plants have been a source of much amusement to readers of this聽column in the past, and I聽anticipate the usual spate of聽chortling comments after this column appears in the paper. Still, consulting such lists at least improves the chances of success in gardens visited by deer.
Dear Helen: I鈥檝e noticed that the issue of improving the texture of heavy clay soils comes up at times in your column. I have the opposite problem. My soil is sandy, super-porous and difficult to keep adequately moist in summer. What鈥檚 the solution here?
H.D.
Though it may seem odd, measures to tighten up the loose texture and improve the moisture-holding capacity of sand-based soils are the same as for opening up the texture of clay and improving its ability to drain well of excess moisture. Adding organic matter on a regular basis is the answer.
Why? For the same reason that fibre in the human diet helps to relieve both constipation and diarrhea.
Clay soils have tiny particles that bind tightly together, excluding air and impeding the flow of moisture. Sandy (gritty) soils have large particles that allow liquids (and nutrients) to flow out too rapidly.
Organic materials, such as compost, manures, cover crops (green manures), chopped leaves, grass clippings and organic mulches, improve the aeration and drainage of clay and increase the ability of sandy soils to stay moist and retain nutrients.
