I bought 2 pots of Bogies over a month ago that came in 2/1'2 pots. According to instructions i should repot them in a 4" pot. Done, and they are growing very nicely. Now the instructions says to fertilize every 2 weeks. Now it says 1/4 tsp of 15-15-15 in a gallon of water. I could only do it in a quart of water, so dumb me don't know the amount to put it in that size. BTW, isn't it an overkill if one pot has just been repotted in brand new soil? Shouldn't that soil have enough of what it needs for a time? Also, we are In August now and most likely they would be brought in Sept or if lucky, early October if the weather cooperates.
