Shrinking Geranium

I use Miracle Grow on my geraniums once a week for a few weeks, then I cut back to once every two weeks and they grow very healthy with beautiful blooms. Maybe this would help your plants. Good luck 🍀

Needs fertilizing every couple of weeks. After each flower bud died off pitch to remove so as nutrienunts ofbthe geranium is to new growth

This is interesting, I had the opposite. I bought a poor looking geranium and it continued to look bad (even though I fertilized regularly. I moved the plant to a different location and it really took off.

I live in texas and we have really hot weather and it takes a toll on my geraniums ! I usually wind up putting them in part shade part sun and pray for rain water!
