And it all starts with selecting the right space for them to grow! Growing beautiful impatiens all begins with selecting a location that protects them from too much sun, while still allowing enough light to the plants for them to flourish. This applies to both bedding plants, and to baskets, pots and containers.
One of the most common reasons impatiens fail is that they are placed in a location that they simply cannot handle. This does not apply to New Guinea Impatiens or Sunpatiens, which can handle full sun. So what is the ideal lighting for impatiens? For best results, select a location that receives no more than 1 to 2 hours of full-on, direct sunlight each day.
In addition, make sure that sunlight is never middle-of-the-day sun. Afternoon sunlight is simply too hot for standard impatiens to handle on a daily basis. It dries out too much moisture from within the stems, and leads to unhealthy and struggling plants. Instead, select locations that receive full sun early in the morning, or late in the evening as the sun sets.
Healthy, thriving impatiens will produce hundreds of blooms per plant. And all of those blooms require and use a lot of nutrients from the soil. Nutrients that need to be replaced on a regular basis to keep plants flowering all season long. Without giving plants an additional source of power, they will simply run out of steam before the end of the growing season. But how you give that power also plays an important role in their bloom cycles.
As with all annuals, liquid fertilizers really are the best choice for the job. Liquid fertilizers absorb quickly into the plants via the roots and foliage. This allows the plant to send plenty of resources to fire up new blooms and flowers. Impatiens respond much better to a lighter dose of fertilizer given at regular intervals. By giving the plants a reduced amount of fertilizer but supplying it more often, it will keep them on a steady growing pace.
Unfortunately, too much power all at once can create more foliage and root growth than blooms. During the growing season, apply a water-soluble fertilizer as you water, every six to eight weeks, to encourage both foliage and flower development. Floridata recommends applying a balanced fertilizer for impatiens, such as a solution. If you're growing impatiens in containers, fertilize more often, approximately every two weeks. A new group of hybrids, mostly with Impatiens hawkeri parentage and native to the island of New Guinea, have been gaining popularity over the past few decades.
Often more temperamental than common impatiens, they can withstand more sunlight, especially strains like SunPatiens. New Guinea impatiens grow taller and more upright, with 3-inch flowers rather than the 1- or 2-inch blossoms of traditional varieties.
Eastern exposures suit the New Guinea cultivars. Although they require more sun than other impatiens, the flowers will be smaller and fewer in number with too much sun. Provide some dappled or light shade in the afternoon to reduce stress.
Also, check the soil moisture frequently as the plants wilt badly when the soil is too dry. Home Guides Garden Gardening. Related Articles. Go ahead and prune deadheads on your plants but avoid trimming the entire stem, or you could be removing potential buds from the plant.
Impatiens are susceptible to root rot, a fungal disease that comes with leaving the plant in wet soil or too much watering- usually killing the plant.
Crowding causes problems and allows plant diseases to spread, so make sure to allow for ample air circulation between plants and seedlings. Spots on the leaves of your Impatiens could be a sign of bacterial wilt, another common affliction for Impatiens. Impatiens like shady spots but also bloom best with daily sun. Too much direct sunlight can burn the leaves and dry the plants out quickly, causing them to wither, curl, and yellow.
Some pests that are a problem for impatiens include spider mites, mealybugs, slugs, snails, and aphids, which cause the foliage to appear discolored and curled. The Tarnished plant bug will dwarf and stunt the impatiens, making the flowers look weird and misshapen.
Treat pests around your impatiens with horticultural oil, such as Neem oil, and remove afflicted plants from your garden. These plants are perfect for beds and borders, thriving in shady spots and blooming the best with a couple of hours of natural sunlight each day. Impatiens do well in most hardiness grow zones but speak with a garden or landscaping professional to learn more!
