Amazing annuals

You may already know what annuals are without realizing that you know! These beauties are the flowers, arrayed in flats and pots, for sale every spring down at the garden center — everything from geraniums to impatiens to marigolds. You bring them home and plunk ’em in the ground, and they get right to work, delivering pretty much continuous color all summer long. When fall comes, they start to slow down (some may even go to seed); cold weather eventually causes them to wither and die. Game over. (That is, unless you live in a frost-free climate; in this case, your “annuals” become perennials. See the upcoming section titled “Perennial plants” for more information.) For the brief time annuals are growing and pumping out flowers, you get a lot of bang for your buck. A great deal of selection and breeding refinements over the years have made these plants totally reliable. They’re hard to kill. Indeed, some of them keep blooming their cheery heads off even when you neglect them. More sophisticated gardeners have been known to sneer at good old annuals. They’re boring. They’re too perky. They’re “plastic plants.” These folks may or may not have a point, but hey, annuals are hard to beat if you want a colorful garden.
In the end, the main drawback of annuals is economic. You have to buy new ones every spring. If you’re planting a wide area, running out to buy more year in and year out can get expensive. Time may also be an issue for you —you may grow sick and tired of getting down on your hands and knees and replanting.
You can use annuals
  • To fill an entire flowerbed (this popular use is why some places call annuals bedding plants)
  • In container displays — in pots, windowboxes, patio planter boxes,and more
  • To fill a hanging basket
  • To edge a walkway
  • To “spot” color in a perennial bed
  • In edging and as decoration for a vegetable or herb garden
  • To cover over or at least distract from a fading spring bulb display If the info you want on annuals isn’t in the upcoming sections.
Caring for and feeding annuals
Luckily, taking proper care of annuals is not rocket science. For the most part, annuals are easygoing, because they’re bred to be quite tough and durable. Many can withstand some neglect and still be productive — not that I recommend ignoring them!
Without a doubt, water is an annual’s number one need. All that lusty growth and continuous flowering requires fuel. A thirsty plant can’t sustain the show for long. Regular, deep soakings are best because they reliably supply water to the roots, which leads to a stress-free life of consistent growth and bud and bloom production. (Note that a drying-out plant favors its roots and, to a lesser extent, its leaves, in a bid for survival, automatically jettisoning its You can’t deny that regular doses of plant food significantly boost your annuals (make sure you apply it according to directions). The leaves become healthier and greener, and you end up with more buds and flowers.
The rather unromantic term of deadheading simply refers to the practice of pinching or cutting off spent flowers. Your annuals look nicer when you do this, of course, but removing the flowers also serves another purpose: It thwarts the plant from the energy-intensive process of producing seeds, and the plant responds by diverting its energy back into making more flowers.
