If you encounter this slimy being in your garden, it’s important to understand its significance

Owning a garden and caring for your plants requires an understanding of potential issues that may arise. If you come across a mysterious substance known as the “jelly nut” in your garden, here’s what you need to know.

Recently, a Redditor from Oklahoma discovered an odd sight in his garden, bright “yellow goo” on his trees and a peculiar object he described as a “gelatinous alien nut”. Unsure of what it was, he turned to the Reddit community for assistance, mentioning that the affected tree was a conifer, though he couldn’t identify it further.

Almost immediately, another user identified the problem as “cedar and apple rust”. This disease depends on two host plants to complete its life cycle, primarily affecting apple and crabapple trees.

The symptoms vary depending on the type of tree. On junipers, a brown gall forms on twigs and produces orange, gelatinous horns in the spring, particularly during wet weather. Although the twig beyond the gall may die, the damage to the juniper is minimal.

For apple and crabapple trees, yellow circular spots appear on the leaves soon after flowering. By late summer, brown clusters of cylindrical structures develop underneath the leaf spots, on twigs, or even fruit.

Galls from the infection can take several months to develop, appearing around seven months after infection begins. After 18 months, they evolve into gelatinous masses. In the spring, these galls develop depressions resembling golf balls, which give rise to telial horns that elongate and turn bright orange during rainy periods. After releasing spores, these horns collapse and dry up, although the galls can remain attached to the tree for another year.

Management of this infection can include pruning the affected areas or simply allowing it to run its course since it typically doesn’t kill trees but may cause some disfigurement. Preventive measures, such as fungicides or planting resistant apple varieties, can also help.

Overall, while cedar and apple rust isn’t a severe threat to your trees, being informed about it allows you to take the right steps if it appears in your garden. Share this information with others so they can be prepared too!

Dealing with Cedar-Apple Rust in Your Backyard

Taking good care of the plants in your backyard can bring you great satisfaction.On the other hand, it also offers a good deal of challenges. Occasionally, you could come upon strange things that leave you scratching your head. Recently, a Reddit user from Oklahoma found something unusual in their trees: a significant quantity of yellow jelly and what they referred to as a “jelly alien nut.” Confused and curious, they turned to the online community for answers.

This mysterious phenomenon was determined to be caused by cedar-apple rust. To complete its life cycle, it requires two hosts; apples and crabapples are the most common hosts. Although the name implies cedars are involved, juniper trees can also be affected.

How to Identify Apple-Cedar Rust

The symptoms of cedar-apple rust vary depending on the type of tree it infects. On the twigs of juniper bushes, brown, persistent galls may develop. When spring weather turns damp, these galls grow orange gelatinous horns. The juniper host is unaffected, however the twig farther away from the gall may die.

The leaves of apple or crabapple trees get circular yellow blemishes shortly after they bloom. As summer progresses, these lesions turn into brownish tufts of threads or cylindrical tubes. They are hidden beneath the blotches on leaves, twigs, and fruits.


Understanding Life Cycle

Now, you might be wondering how long this ailment lasts. Well, galls start to form seven months after the initial disease. After eighteen months, they turn into gelatinous lumps. The galls produce golf-ball-shaped depressions from which telial horns emerge the following spring. When it rains in the spring, the brownish telial horns spread out and become a vivid orange color. When they release their spores, the horns eventually droop, dry out, and fall off. After they die, the galls remain attached to the tree for as least a year. The infection is most noticeable in the spring when the galls are covered in gelatinous masses.

Managing Cedar-Apple Rust

Fortunately, there isn’t much of a treatment for this infection. Cut off the afflicted areas to prevent the illness from spreading. It’s crucial to keep in mind that cedar-apple rust won’t kill your trees—it will only damage the plants’ aesthetics. If you would rather be proactive, you can use fungicides or select apple cultivars that are resistant to this disease.

To sum up

In conclusion, even though you might not often see cedar-apple rust in your backyard, your trees are not in grave danger. It’s essential to comprehend this infection so that, in the event that it materializes, you can respond appropriately. Tell people about this information so they too can recognize and understand cedar-apple rust. I’m toasting to your productive gardening!
