Palm

There are many things going on here. I see signs of accumulation of soluble salts on the soil. You should water thoroughly several times in quick succession to remove the unwanted salts thatt are causing leaf edge burning. You have other plants growing with the palm that could act as repositories for insect pest and diseases. The plants should be removed. We have looked carefully at the image as requested, however, given the vast array of variables that cause plant growth, it is impossible to determine exactly when your palm will grow as you want it. Make certain the plant receives full sun, adequate slow release fertilizer designed to feed palms with minor nutrients (especially manganese and magnesium) and provide well drained soil
