Hi Sheryl, welcome to 'epi world'. In the winter months, my plants may get watered every 1- 1 1/2 months, lightly so that the leaves don't become shriveled, or the soil too dry, but not soaking wet. Some people don't water them at all during the winter. I don't really pay them much attention, once I've brought them inside
I do fertilize the plants after about 6 months. I'm happy to hear that C. Sue doesn't fertilize. I may try that with some new cuttings to see if they bloom any faster
If you do plan on fertilizing, stop in the fall, when plant growth slows down. An excellent discussion of fertilzation can also be found at
http://mattslandscape.com. This is the main source where I get my epi and cacti cuttings, and he gives a lot of useful information about cacti and epiphyllum care. Promise not to look at all the lovely blooms, or all of the cuttings he has for sale
Be careful about growing the plants in full sun. The leaves can burn, and on some plants, they will turn red with too much sun expsure.
Happy Growing!
