When planning your garden, placement of certain plants should be taken into account. Permanent locations must be picked out for plants with a longer life-span, such as asparagus, horseradish or ginger. Herbs are best potted or contained, as they tend to spread. Keep in mind a plants’ sun requirements when picking out a spot; some can grown in partial shade while others, like garlic or onion, require full sun. Also consider your plants predicted height into your plans, to prevent one crop from shading another.
