Okay, so I’ve been growing lilies for a while now, and let me tell you, it’s mostly smooth sailing. They’re pretty easy to take care of. But sometimes, you run into some unwelcome guests, or your lilies start looking a bit under the weather. It happens. I learned that over time!
First off, the critters. The biggest pain in the neck is probably the lily leaf beetle. These little red devils just munch away at the leaves, leaving ugly holes everywhere. I remember one time I discovered some damage, and I spent ages looking for the issue, and then I realized it was these beetles. So I started picking them off by hand at first, which is, yeah, not fun. I remember putting them into a bowl of soapy water, not a fun thing to watch, but you got to do what you got to do.

Then there are aphids. Those tiny green or black bugs that suck the sap out of the plants. They’re sneaky, but I found them on the underside of the leaves. I used a strong spray of water to knock them off the plants. After that, I tried out insecticidal soap, that worked. It was quite easy actually, just sprayed and kept an eye on it.
And you can’t forget about slugs and snails. They love to come out at night and feast on young lily shoots. It took me some time to notice this. I used to find trails of destruction and damaged shoots in the morning. To battle them, I set up beer traps. Basically, you just bury a container level with the ground and fill it with beer. They’re attracted to it, fall in, and well, that’s the end of them. And I started putting crushed eggshells around the base of my plants to deter them.
Now, onto the diseases. Botrytis blight is a common one. It’s a fungus that causes brown spots on the leaves and flowers, and sometimes the whole plant just rots. It really was a sad sight when I saw my lilies like that for the first time. You see these fuzzy gray molds, and you just know it’s bad. I learned the hard way that good air circulation is key to preventing this. I used to plant my lilies really close together, but that was my big mistake. So I started spacing them out more. And I started watering them at the base instead of overhead to keep the foliage dry. And when I saw any infected parts, I immediately removed them and got rid of them. You don’t want it to spread.
Another one is basal rot. This is nasty because it attacks the bulb itself. The leaves start to yellow and wilt, and the whole plant eventually dies. I lost a few plants to this one before I figured it out. You can tell when the bulb feels soft and mushy. It’s not pretty, but you must have a look at it. The best thing here is prevention. Make sure you have well-draining soil and don’t overwater. I even started inspecting the bulbs before I planted them to make sure they were healthy. It’s like checking the fruits in the supermarket.
Here’s a little breakdown of what I just said:
Common Pests:
- Lily Leaf Beetles: Hand-pick and destroy.
- Aphids: Spray with water or use insecticidal soap.
- Slugs and Snails: Use beer traps or crushed eggshells.
Common Diseases:
- Botrytis Blight: Improve air circulation, water at base, remove infected parts.
- Basal Rot: Ensure well-draining soil, don’t overwater, inspect bulbs before planting.
So, yeah, that’s my experience with lily pests and diseases. It’s been a learning curve, for sure. But with a bit of vigilance and some elbow grease, you can keep your lilies healthy and beautiful. Trust me, it’s worth the effort. And it’s always fun to learn something new in the garden, even if it’s because of a pesky beetle or a nasty rot. And remember, gardening is always a learning experience, don’t get discouraged.
