I did a batch of lemon cuttings and all failed to grow. I then decided to pull them out and found small thread-like worms eating the ends of the cuttings. This also happened to the seeds I stated, after I germinated the seeds, I planted them and they never showed up, so again I dug up the seeds and found that the inside of the seed became white mush filled with the same worm.

In the video I put the cutting under water and took the video through a magnifying glass.
