Date palms are raised from seed, so it's unlikely the home grower will do much propagation. When coming across a viable date seed, know that they have a strange germination pattern, called remote germination. This means that the date palm seedling will emerge from the soil a short distance away from the actual seed. Seeds shouldn't be planted especially deep, and expect germination to take several weeks at least.All varieties of date palms, including pygmy palms, do well slightly pot bound, so repotting of mature plants should only be carried out every other year. For those who let plants go too long without repotting but still have a palm with strong roots, know that the pot will eventually break, if you use plastic. When repotting, be careful of the plant's spines, and use gloves.
