Impatiens Plant Companions – What to Plant with Impatiens in the Garden Impatiens [1] are a long-time favorite for adding a pop of color to shady beds. Impatiens bloom from spring until frost and can fill the gaps between blooming periods of shade perennials. Growing in small mounds no larger than one foot (0.5 m) high and two feet (0.5 m) wide, impatiens can be hidden in bare areas in the shaded garden. Their compact growth makes them ideal for shady bedding plants or borders.

Companion planting with impatiens

Before I get into what to plant with impatiens, let me tell you what impatiens bring to the table as companion plants. Impatiens attract beneficial insects. As mentioned above, they add long-lasting, vibrant color to dark, shadowy areas and create excellent borders.

The fleshy, succulent-like stems of impatiens store water and make them drought-resistant, so they don’t compete with other plants for water and can be used in dry shade beds. As companion plants, the dense foliage of impatiens can keep the soil moist and cool for its companions.

Impatiens Turns Yellow: What Causes Yellow Leaves On Impatiens Plants?

My impatiens have yellow leaves

It’s a sad day in the garden when you see your impatiens turning yellow leaves. Generally, impatiens are disease-free annuals in backyard beds and display healthy, dark green leaves.

However, the plant is very sensitive to water stress. The key to healthy impatiens is to keep the soil always moist, but never soggy. Overwatering and underwatering can cause impatiens leaves to turn yellow.

What causes yellow leaves on impatiens?

Aside from improper watering, a variety of pests and diseases [2] can cause yellow impatiens leaves.

Nematodes – One cause of yellow leaves is an infestation of nematodes [3] , tiny, slender worms that live in the soil and attach themselves to the roots of plants. If plants are slow to recover after midday wilt, nematodes are likely the cause of yellow impatiens leaves. Dig up the infected plants with the surrounding soil and throw them in the trash.
Downy mildew – Another possible reason for your impatiens’ leaves turning yellow is a fungal disease – namely downy mildew [4] . Look for brown spots on the stems before you see the leaves turn yellow. Since impatiens are annuals, it’s not worth using pesticides. Simply dig up the infected plants and nearby soil and discard it.
Botrytis Blight – If, in addition to saying “My impatiens have yellow leaves,” you say, “My impatiens have wilted flowers and rotting stems,” you are considering Botrytis blight [ 5] . Increase the air space between plants and provide plenty of freedom of movement, these are the cultural steps to combat this infection.
Verticillium Wilt – A final possible cause of impatiens having yellow leaves is verticillium wilt [6] . For both this and botrytis blight, you can use a fungicide [7] specifically for impatiens.

Pinch the growing tips [3] of newly planted condo cockatoo impatiens to encourage full, bushy growth. Cut the plant back by 3 to 4 inches if it looks tired and leggy in mid-summer.

Impatiens and Downy Mildew: Alternatives to Planting Impatiens in the Garden

Impatiens [1] are one of the standby color choices for shady regions in the landscape. They are also threatened by a water mold disease that lives in the soil, so check these shade annuals carefully before purchasing them. There is a serious disease of impatiens (called downy mildew [2] ) that is species-specific and kills the plants. It has the ability to overwinter in the soil, making it a threat for years to come even if you don’t bring in affected plants. One way to avoid problems is to use alternatives to planting impatiens and give the soil a chance to clear the mold.

What are the causes and symptoms?

The impatiens fungus is caused by the pathogen Plasmopara obducens, which is very difficult to control. The fungus on impatiens plants forms in cool, damp, or humid conditions, generally in spring or fall. Ornamental impatiens and downy mildew go hand in hand in 30 states in the Union, with few resistant varieties available. It affects both cultivated and wild impatiens, but not New Guinea impatiens [3] .

Downy mildew [2] begins on the underside of leaves and causes them to fade and develop spots, similar to heavy spider mite feeding [4] . The leaves become limp and eventually white, cotton-like spores appear on the leaves. Eventually all the leaves fall off and you are left with a skeleton of a plant. Without leaves, the plant can no longer feed itself on carbohydrates harvested through photosynthesis [5] , and it will wither and die. Any fungus on impatiens plants is contagious to other plants in the group but does not affect other ornamental species.

What to do about impatiens and downy mildew?

The impatiens fungus is actually not a fungus, but mildew and as such does not respond to fungicides. There are applications that work as a pre-emergence, but once the plant has the disease there is nothing to do except remove it from the garden. The mold is already in the soil at this point and it is therefore not advisable to replant impatiens as the pathogen can overwinter and lurk until its preferred host is within reach.

Using plant alternatives for impatiens downy mildew is the best choice to prevent plant death. There are many shade-providing ornamental plants that are suitable alternatives to planting impatiens.
