7. Care for two or more perennial flowers growing outdoors for one season by fertilizing, watering, weeding, and treating for pests as needed. Maintain a written record with weekly entries, listing work done.
You can apply the same techniques given above for annuals to care for perennials, but with perennials, there is more impetus to get it right. If you get it right, they will come back the following year. Indeed, if you already have a bed of perennials, there is no need to plant them at all. Just fertilize and water them, and make sure you keep the pests at bay. If the plant makes it through the fall in good health, chances are excellent that it will survive the winter and be healthy again in the spring.
