Hello, I'm new to this forum but I am pretty good with plants. Like the title says, I would like to know how I can grow Joshua tree seeds. The instructions tell me to put 3 or 4 seeds in a 16 inches wide and 24 inches deep pot. Then, I keep the strongest seedling that sprouted and I take out of the pot the other ones that are weaker. Is this a good idea? What do I do with the order seedlings in the pot? Are there other better ways to grow a JT seed.
