Today, I decided to get my hands dirty and really dive into understanding what’s been plaguing my impatiens. They haven’t been looking their best, and I wanted to figure out why.
Identifying the Issues
First, I grabbed my gardening gloves and a magnifying glass. I’ve learned over the years that a close inspection is key. I started by examining the leaves. Some had yellow spots, others had a white, powdery substance on them, and a few were just wilted and sad-looking.

- Yellow Spots: This looked suspiciously like downy mildew, something I’ve dealt with before.
- White Powdery Substance: This was probably powdery mildew. Ugh, not again!
- Wilted Leaves: Could be a few things: too much or too little water, or maybe even a pest infestation.
I carefully turned over some leaves, and bingo! I saw some tiny, almost invisible, spider mites. Little buggers! I also noticed some leaves with irregular holes, it is likely that snails or slugs, that I usually find at night with my flashlight.
Taking Action!
Once I had a better idea of what I was dealing with, I started tackling each problem:
-
Downy Mildew: I removed all the affected leaves and sprayed the plants with a fungicide. I know some folks prefer organic options, but in my experience, a good fungicide is sometimes necessary.
-
Powdery Mildew: I mixed up a solution of baking soda and water and sprayed that on the affected areas. It’s a simple remedy, but it works wonders.
-
Spider Mites: I blasted the plants with a strong stream of water from the hose to knock off as many mites as possible. Then, I applied some insecticidal soap, making sure to get the undersides of the leaves.
-
Snails and Slugs:At night, equipped with a flashlight, I went on a hunt, I have collected most of them and moved to the forest near my house.
Watering: I’m going to be extra mindful about watering. I stuck my finger in the soil, and it felt a bit dry, so I gave them a good soaking. I’ll keep a close eye on the soil moisture going forward.

Keeping an Eye on Things
Now it’s all about observation. I’ll be checking on my impatiens daily, looking for any signs of the problems returning. I also made a note in my gardening journal to remind myself to reapply the treatments in a week or two, just to be safe.
It’s a bit of work, but seeing my impatiens thrive is totally worth it. Gardening is always a learning experience, and today was a good reminder that even experienced gardeners face challenges. It’s all about figuring out what’s wrong and taking the right steps to fix it.
