Why do my leaves lay over?  How come they’re yellow?  What are those holes in the leaves? My plant just doesn’t look healthy, what’s wrong?  UGH, the toughest part of gardening is trying to figure out why a plant isn’t thriving!

Here are some questions that a Master Gardener might ask of you to find out what’s wrong with your plant?

  • Exactly what kind of plant is it? (may sound easy but some folks don’t know)
  • Is it growing in the right conditions?  Are it’s requirements being met?
  • Compared to a healthy plant, what is wrong with yours?
  • If the leaves are brown or yellowed, are they crispy or flexible?
  • Do you see signs of insects?
  • Are there brown spots on the leaves?  If so, are they round or random? New leaves or old leaves?

Aphids love nearly everything! And come in a variety of colors too…

Oftentimes there is more than 1 reason a plant is not doing well.  In trees, it can take years to show decline.  Weather conditions play a huge role in issues with large plants!
