Well, hello there! Today, we’re gonna talk about them lily pests and diseases. You know, the things that make your pretty lilies look like they’ve been through a war. I’ve seen my fair share of these troublemakers, and let me tell you, they ain’t pretty. So, let’s get down to business and figure out how to keep them lilies happy and healthy.
Pesky Critters: Lily Beetles and More

First off, we got them lily beetles. Them little red devils are bad news. They munch on the leaves and flowers, leaving ugly holes and slimy messes. You’ll see ’em crawling all over, big ones and small ones. The grown-up ones are red, real bright, and the young’uns are kinda yellowish-brown and slimy. Ugh! They lay eggs on the leaves, and them little wormy things hatch out and start eating too. It’s a real mess, I tell ya.
- What to do: Well, the best thing to do is to pick them off by hand. Yep, just grab ’em and squish ’em. Sounds nasty, but it works. You gotta be quick though, them beetles are fast. You can also use some of that neem oil stuff, it’s supposed to kill the young ones. Spray it on the leaves, and it’ll make them beetles think twice about eating your lilies. And if things get real bad, there’s some stronger stuff you can buy at the store, but be careful with that, it can be bad for other things too.
Nasty Diseases: Botrytis Blight and Other Troubles
Now, them bugs ain’t the only problem. Lilies can get sick too, just like us. One of the worst is that botrytis blight. It makes the leaves and flowers turn brown and mushy, like they’re rotting. It looks like mold, kinda grayish and fuzzy. It spreads fast, especially when it’s wet and damp. You’ll see it starting on the lower leaves, and then it works its way up. Before you know it, the whole plant is a mess.
- What to do: If you see any leaves or flowers that look sick, you gotta get rid of them right away. Cut ’em off and throw ’em in the trash, don’t leave ’em laying around. And make sure your lilies ain’t too crowded, they need air to breathe. If they’re too close together, they’ll stay wet longer, and that’s when them diseases like to grow. Watering them from the bottom, instead of getting the leaves all wet, that can help too.
Another bad one is that Fusarium wilt. That one’s sneaky. It gets into the roots and makes the plant wilt and die, even if it looks like it’s got plenty of water. You might not even know you got it until it’s too late. The leaves will start turning yellow and droopy, and then the whole plant will just collapse. It’s a sad sight, I tell ya.
- What to do: The best way to deal with that Fusarium stuff is to prevent it in the first place. Make sure you buy healthy bulbs, them sick ones can spread the disease. And don’t plant your lilies in the same spot every year, move ’em around a bit. If you do get a sick plant, you gotta dig it up and get rid of it, roots and all. And don’t plant another lily in that spot for a while, give the soil a chance to rest.
Keepin’ Them Lilies Healthy
So, there you have it, some of the common lily pests and diseases. It ain’t always easy keeping them lilies looking their best, but it’s worth the effort. Just keep an eye on them, and if you see something that don’t look right, take action right away. And don’t forget to give them lilies plenty of sunshine and water, and a little bit of food now and then. They’ll thank you for it with beautiful blooms, and that’s what it’s all about, ain’t it?
Remember, healthy soil is important too. If your soil is good and rich, your lilies will be stronger and better able to fight off them pests and diseases. So, add some compost or manure to your soil every year, it’ll make a big difference. And make sure your soil drains well, lilies don’t like to sit in wet feet. If the water just sits there, the roots will rot, and that’s bad news.

One more thing, peace lily plant diseases are similar in some ways but different too. Peace lilies are those indoor plants with the pretty white flowers. They can get some of the same diseases, like that botrytis blight, but they also have their own problems. If your peace lily leaves are turning yellow or brown, or if they have spots on them, it could be a disease. You gotta treat them just like you would your outdoor lilies, remove sick leaves, make sure the soil is good, and don’t overwater them.
Well, I think that’s about all I got to say about them lily pests and diseases. Just remember to keep an eye on your lilies, and take action if you see something wrong. With a little bit of care, you can keep them lilies blooming pretty for years to come.
