The year before last, my oldest plum tree had a bumper crop of plums. A squirrel or some other critter was also enjoying a few of the plums, and dropped the seeds to the ground beneath the tree after eating some plums.
I noticed the numerous plum seeds on the ground as I was walking by, and quickly gathered up as many as I could find. I was working on another project that day that I was trying to finish up, so instead of diligently planting the plum seeds, I think I remember using a shovel to break up the soil in a nearby spot, and I may have made a slightly raised area. I pushed the seeds into the soil with my thumb, about an inch down, pressed the soil firmly on top of them, and may have covered it with a very light mulch. I may have spent ten minutes collecting and planting the seeds.
I was walking by this spot the other day, almost two years later, and had completely forgotten about the plum seeds that I had planted here previously. The area is now filled with numerous wild plants, and I was looking at another tree that I had planted nearby, when I noticed what looked like a patch of small trees growing. Upon looking closer, there leaves were just coming out, and I noticed that they looked like little plum trees. My mind flashed back to the memory almost two years ago, when I had planted the plum seeds here. There are about thirty plum seedlings growing in this area all close together. It's hard to beat getting about 30 plum seedlings with about 10 minutes of work.
Sometimes it's nice to be just plum surprised.
