From this University of Hawaii Cooperative Extension pub:
"Ti needs occasional applications of a general garden fertilizer at 3–4-month intervals. The fertilizer ratio of the major elements should be 3:1:2 for N, P, and K, respectively. Apply 35 pounds N-P2O5-K2O per 1000 square feet per year. Increase the application in heavy rainfall areas or if frequent irrigation is applied. An N-P-K ratio of 1:1:1 is recommended for soil-based media, whereas a ratio of 3:1:2 is suggested for soilless media.
Another common nutritional program is liquid feed with 24-8-16 or 20-10-20 N-P-K formulation, following the product directions. Liquid fertilizer should be rinsed off the foliage with water."
Cindy, I have been growing Ti's personally and commecially for decades and we propagate thousands of them each year. We alays use a combination of fertilizer and alternate the brands.Our method is to use small doses every 2 months or so in the gowing season. Too much balanced fertilizer will lessen the vibrance and Black Kow cow manure will aid in increasing the color. I also supplement with coffee grounds, epsom salts,and I use natual fetilizers,and they thrive. The trick to keeping them healthy also is a well dained soil and be sure to cover in the winter!.
Garden Rebel/sims landscaping,Co. I would love to know more about the coffee,epsom salt, and natural fertilizers you use on your TI
