How often do you replant citrus in a pot
My sister grows citrus tree in a pot on her patio in the Bay Area. She indicated that it's been in the same pot for several years. She does fertilize it every couple of months using some sort of Miracle Grow blue crystal fertilizer that attaches to a hose.
I don't grow trees in pots, but repot house plants every couple of years, so I was wondering how often does citrus trees needs to be repotted even if it is fertilized?
I was also going to suggest that she try to use a granular fertilizer for citrus because it would be even less work and won't spray fertilizer all over the place.
