The 10-10-10, I apply monthly because it is not a slow release type.

Use Potassium sulfate which is 0-0-50 or 0-0-52. Check the NPK as this may vary from different sources. ... Potassium Chloride is also available, but in time the chloride salt could be a problem. These are available at garden centers in 5 lb bags for $6 to $8. I got my potassium sulfate from Southern States. I carried in a 5 gal bucket and they filled it about 1/2 full. It weighed 24 lbs and they charged me $8.

My fertilizer program is to apply 9 oz (1 cup) of 10-10-10 Plus every month per plant and with 8 oz (1 cup) of Potassium sulfate every 2nd (other) month to the mat.

To this I plan to be testing folar spray as needed if the plant appears distressed and when it starts to flower.

Any of the triples or balanced fertilizers (8-8-8;10-10-10; 15-15-15) will work. Just adjust the quantities applied as needed. Use what is available and gives you the most bang for a buck.
