Well, hello there! Today, we’re gonna yak about them impatiens, you know, the pretty flowers everyone likes. But listen up, these little things ain’t always so easy to grow. They got their own troubles, just like us. Yep, diseases and pests, they got ‘em too.
Common Impatiens Diseases

First off, let’s talk about the sicknesses them impatiens can get. One bad one is downy mildew. It’s a real pain, I tell ya. You’ll see yellow leaves, and then this fuzzy white stuff on the bottom. Looks like someone sprinkled flour all over ‘em. And then, poof! Your flowers are gone. It spreads fast, too, specially when it’s wet and cool. So, if you see it, you gotta act quick. Get rid of the sick plants, and don’t water from the top, you hear? Water the roots, that’s what I always say.
- Downy mildew: Looks like white powder on leaves, spreads fast in wet weather.
- Root rot: Roots turn mushy and black, plant wilts and dies. Caused by too much water.
- Botrytis blight: Causes brown spots on flowers and leaves, especially in cool, damp conditions.
Another thing is root rot. That happens when you water ‘em too much. The roots, they start rottin’ away, turnin’ all black and mushy. The plant, it just wilts and dies. So, don’t drown them poor things! Let the soil dry out a bit between waterin’. That’s what I do, and my flowers, they do alright.
Then there’s Botrytis blight. This one, it makes brown spots on the flowers and leaves. It likes it when it’s cool and damp. So, make sure your plants ain’t too crowded, give ‘em some air. And clean up any dead leaves and flowers, you know, keep things tidy.
Pesky Pests that Bother Impatiens
Now, let’s get to them critters that like to munch on our impatiens. First up, we got aphids. Tiny little things, but they cause a big mess. They suck the juice outta the plants, makin’ ‘em weak and twisty. You’ll see ‘em clustered on the new growth, little green or black dots. If you don’t have too many, you can just squish ‘em. Or you can use some soapy water, that works too. Just spray it on ‘em.
- Aphids: Tiny bugs that suck plant sap, causing twisted leaves and stunted growth.
- Spider mites: Very small mites that cause yellowing and stippling on leaves, may make fine webs.
- Whiteflies: Small, white, moth-like insects that fly up when disturbed, also suck plant sap.
- Slugs and snails: Chew holes in leaves, especially at night, leave slimy trails.
Then there’s spider mites. These are even smaller than aphids, hard to see, but you’ll notice the damage. The leaves, they get all yellow and speckled. And if you look close, you might see tiny webs. They like it hot and dry, so keepin’ things moist can help keep ‘em away. There’s special stuff you can spray for ‘em too.
And don’t forget about whiteflies. They’re these little white things that fly up when you touch the plant. They suck the juice too, just like aphids. You can use sticky traps to catch ‘em, or spray ‘em with that soapy water.

Last but not least, them slimy slugs and snails. They come out at night and chew holes in the leaves. You’ll see their shiny trails in the mornin’. You can pick ‘em off by hand, if you got the stomach for it. Or put out some beer traps, they like that stuff. They crawl in and drown, silly things.
Keeping Your Impatiens Healthy
So, what can you do to keep your impatiens healthy and happy? Well, first off, plant ‘em in the right place. They like shade, not too much sun. And make sure the soil drains good, they don’t like their feet wet all the time. Water ‘em regular, but don’t overdo it. And check ‘em often for any signs of sickness or bugs.
If you do see somethin’ wrong, act fast. The sooner you catch it, the easier it is to fix. And if you’re not sure what to do, ask someone at the garden store. They usually know a thing or two.
That’s about it, I reckon. Impatiens ain’t hard to grow, but you gotta keep an eye on ‘em. Just give ‘em a little TLC, and they’ll reward you with pretty flowers all season long.
Take care now, and happy gardenin’!
