Hi, Nancy!
For me one of the hardest things to do is...nothing! Wait, wait & wait some more and see what actually happens. Sometimes a keiki will develop as a result of stresses to the parent plant and is nature's last ditch effort at survival. They can also form as a result of chemical or hormonal influences which trigger the plant. A keiki from the node on the spike should eventually form it's own roots and then can safely be removed. Basal keikis, from the main stem of the plant, I never remove. They are simply too tricky for me and I worry about fungus, infections, etc. That's just me...Good luck with it (or is it them...)Remo!
