This Disease Can Ruin Your Apple Tree 🍎
Apple cedar rust requires two different hosts to complete its life cycle.
One year it infects juniper (Eastern red cedar), and the next it infects apple trees.
In the spring, you’ll notice orange, jelly-like galls forming on infected junipers. Once the weather turns warm and wet, they release spores that travel to nearby apple trees.
After the apple tree becomes infected, orange spots appear on the leaves. Later in the season, new spores develop on the underside of those leaves and spread back to the junipers, starting the cycle all over again.
There are fungicides you can spray in the spring to help control apple cedar rust, but personally, I don’t bother.
I’d rather grow apple varieties with good natural resistance than spend my time spraying.
Where I live, Eastern red cedar is everywhere, so choosing resistant varieties just makes more sense.
If you’re planting apple trees this fall, next spring, or sometime in the future, here are a few varieties worth looking into:
🍎 Liberty (my personal favorite)
🍎 Freedom
🍎 William’s Pride
🍎 Enterprise
🍎 Davey
Keep in mind that “resistant” doesn’t mean maintenance-free.
Young trees still need proper watering, mulching, and general care—especially during the first two to three years while they’re becoming established.
Hopefully this helps! 🌱
Have a great day.
