This video is an update on “Planting Queen Palm Trees.” Here is the link for that first video:    • Planting a Queen Palm Tree  

My fertilization techniques for my Queen Palms are as follows:
I apply Miracle Grow Shake ‘n’ Feed Palm Food every three months as directed on the container. Between each feeding at around 8 weeks, I apply 4 ounces of Southern AG Palm Nutritional Spray liquid micronutrients to 4 gallons of water to each of my palm trees which is only 50% of recommended feeding as per its container instructions. Miracle Grow Palm fertilizer has the palm’s NPK (or macronutrients) and its needed micronutrients. But to assure my trees are receiving their vital micronutrients, I use Southern AG Palm Spray to lightly feed my trees in between their required full feeding. What is my rational? I have soil that is both sandy and rocky. As a result, it drains relatively quickly which means nutrients can flow below their roots, making them theoretically out of reach. Therefore, I use Southern AG as backup insurance for getting micronutrients onto their roots.
(Finally, in midspring after the rains, I add an acidifier made by Espoma. I use about onehalf cup to keep the trees’ soil pH around 6.5)
