Growing Edibles in your Landscape
This is something that seems like a no-brainer that everyone can get excited about. As long as you are growing plants, why not grow something you can eat? For the most part that is true, however, at the coast it's so much easier said than done for two major reasons: deer and elk. Most of the plants that we like to eat are also deer candy. This is especially true of apple and pear trees as they are in the rose family. Every enthusiastic new coastal gardener has quickly learned the hard way that roses impossible to grow at the coast. Deer repellents do work for most plants when applied on a weekly regime, but not for roses. Yes, for ruminants, anything in the Rosaceae family is tasty enough to still be worth eating even when doused in "putrified egg solids", castor oil, blood meal, and sprinkled with cayenne pepper.
When a client is serious about growing food the first step is to put up a fence or deal with individually caged beds or trees. If this is not something desirable, either for aesthetic reasons, or for HOA code, then you can still grow artichokes and most herbs. Deer won't touch artichokes, rosemary, thyme, savory, lovage, sage, and most other oily plants. Also, not all fencing and cages are ugly. Personally, I like the look of non-galvanized steel remesh as it ages to a lovely rusty patina that disappears into the surrounding landscape. It can also be installed in a way so that the fencing panels are removal and can be lifted out for access.
Salt air and wind are two other factors that can limit the success of fruit and veggies at the beach and on coastal headlands. Cloches, cold frames, or agricultural spun row covers are an excellent means of protection against wind, excess rain, salt spray, and also many common pests.
