It’s crazy. They grow those nubbins out, and then…. Bam! They explode open and the flowers grow super fast. Whatever sweet nectar they produce, it must be great. First tons of honey bees come, then tons of other little bees and fly-like things and ants for a long time. Looks like soil they would like. Bet they would like a lot of water and fertilizer during the hot months in that calcareous mix. Mine actually need a lot of potassium and boron, in addition to enjoying regular high end palm fertilizer, and my soil is much better than this, but still very sandy. Mine are on the very edge of the irrigation zones, and get hit 3x per week, but it’s a little light. I’ll soak them with a hose once a week when it gets dry. They can survive terrible dryness and bad soil, but still enjoy some TLC to speed them up.
