Dealing with Cedar-Apple Rust in Your Backyard

Taking care of plants in your backyard can be a fulfilling experience. It does, however, also provide a significant number of difficulties. You could occasionally come upon odd things that make you scratch your head. A Reddit member from Oklahoma recently discovered something strange in their trees: a large amount of yellow jelly and something they called a “jelly alien nut.” Perplexed and intrigued, they looked to the internet community for clarification.

Cedar-apple rust was identified as the cause of this enigmatic phenomena. It needs two hosts to finish its life cycle; the most common hosts are apples and crabapples. Despite the name’s suggestion that cedars are involved, juniper trees can also experience it.

 

How to Spot Cedar-Apple Rust

Depending on the kind of tree it infects, cedar-apple rust presents with different symptoms. You may see brown, persistent galls growing on the twigs of juniper plants. These galls develop orange gelatinous horns as the spring weather turns wet. The twig that is farther away from the gall might perish, but the juniper host is untouched.

Circular yellow lesions develop on the leaves of crabapple or apple trees soon after they bloom. These lesions become brownish tufts of threads or cylindrical tubes as summer wears on. They are under the spots on fruits, twigs, and leaves.

Comprehending the Life Cycle

You may now be asking how long this illness persists. Well, seven months after the first illness, galls begin to form. They become gelatinous lumps after 18 months. The following spring, telial horns emerge from golf-ball-shaped depressions that grow on the galls. The brownish telial horns extend and turn bright orange in the springtime rain. Upon releasing their spores, the horns gradually collapse, get parched, and fall off. The galls are stuck to the tree for at least a year after they die. When the galls are covered with gelatinous masses in the spring, the infection is most visible.

Handling Apple-Cedar Rust

 

Thankfully, treating this infection is not too difficult. To stop the infection from spreading, you can trim off the affected parts. It’s important to remember that cedar-apple rust just harms the plants’ appearance; it won’t destroy your trees. You can choose apple cultivars that are resistant to this disease or use fungicides if you would rather take a preventative approach.

In summary

To sum up, while cedar-apple rust may be an uncommon sight in your backyard, your trees are not seriously threatened by it. It’s critical to understand this virus so that you can take appropriate action if it manifests. Spread the word about this knowledge so that others can identify and comprehend cedar-apple rust. Cheers to your successful gardening!
