Even if you’re doing everything right, your willow tree might run into a few health issues now and then. Don’t panic, though! It’s usually not a huge deal. If you catch the signs early, you can get your tree back on track in no time. Here’s what you need to keep an eye out for.

First, check the basics

If you notice the leaves looking a bit funky or the growth seems stunted, it’s not always a disease. Sometimes, the tree is just unhappy with its environment or needs a little extra TLC. Before you jump to conclusions, double-check that your willow’s basic needs are being met.

Common culprits for a struggling willow:

  • Not enough sunlight
  • Thirsty roots (under-watering)
  • Nutrient-poor soil
  • Soil that’s too compacted, which chokes the roots

If you’re in doubt, a few quick fixes can make a world of difference. For instance, a little fertilizer can provide a much-needed nutrient boost. I also recommend spreading some bark mulch over the willow’s roots. Mulch is great because it holds onto moisture and nutrients, releasing them slowly to keep the tree happy over time.

Common willow diseases

Willows are unfortunately prone to various fungal infections. If you see leaves turning strange colors, getting covered in a fuzzy coating, or drying out, you’ll want to act fast. Fungi slowly drain the life out of a tree, and without intervention, it could eventually die. The good news? Willows are incredibly resilient. Even after a heavy pruning, they bounce back quickly.

Keep an eye out for these common fungal issues:

  • Willow scab
  • Rust
  • Powdery mildew
  • Marssonina (anthracnose)

The earlier you spot the infection, the better. Simply prune away any affected branches. Make sure to burn the clippings or seal them in a yard waste bag for disposal. Whatever you do, don’t toss them on your compost pile! If you do, the fungus can survive and spread throughout your garden next time you fertilize. If the infection is really out of control, you could consider a fungicide, but keep in mind that means introducing chemicals into your backyard ecosystem.
