Need help with mango Toledo seedling
A Southern Florida friend sent us 11 mangoes Toledo to satisfy my fifty years of craving for it. I eat the first 3, they were delicious, and I had 3 seeds. I wanted to germinate them really bad so I could have my own tree. Since I had problems in the past controlling the amount of water, they either ended up too wet or too dry and to avoid having to worry too much about it, I decided to try to germinate the seeds by designing my own seedling pot using a couple of 1 gallon water bottles. I made it in a way that I didn't had to put water over the media itself. This way I just had to fill the bottom section until it gets full and the excess water leaks out without touching the media.
I got the pot ready, with 3 seeds inside, resting in a shaded spot with a lots sunlight. I forgot about it for 2 weeks. When I came back to check on it, and to my surprise, I found they had germinated with more than one seedling per seed and they were growing up really fast. In the past I only had germinated mangoes with one seedling per seed and they took a while to do it. Now I don't know what to do next. One is 7 inches tall already, should I transplant it now or wait. Someone help me, please. Thank you!
