Many home gardeners equate the growing of perennial plants with low-maintenance gardening. There are some excellent reasons for preferring perennials to annuals, but saving time and maintenance costs is not one of them.
It is common to find amongst home gardeners, the idea that perennial flowering plants demand far less care and attention than annuals. As annuals live for no more than a season, an annual flowerbed has to be re-planted at least twice during the year, and more usually once more within a season. Conversely, because perennials live beyond a single season, they are often considered a factor in “low-maintenance gardening?. This view from my 24 years gardening experience, is false.
