Come early October the first step should be watering with Epsom Salts only, one tablespoon per gallon for three waterings followed by just fresh water and plenty of it right through blooming. Do not give it any fertilizer until it blooms again. The recommendation was to dry them but in their natural environment they get daily dew. It also helps to pull off the terminal leaf from each maturing cane as this will reinforce the end of growing and stimulate bud initiation. Also keep them bright and cool during dormancy.
Hope you didn't go too large with the pot. Dends like their roots tight.
