Hey guys, I'm wondering if someone can help me out with some of my plants?... (#1) My lychee tree is grown from seed, about 2 years old, and has been doing well, other than the tips of its leaves which have always been brown. Could this be from the cold? (Toronto's climate isn't much like China's!), or should I be worried? Is there any way to fix this? (#2) I'd actually assumed this ornamental pepper was dead, until my boyfriend pointed out new blossoms on it. No idea how it managed to bloom despite my treating it as departed the entire winter, but is there anything I can do to help it along? Also can anyone give me an official name for this plant? (#3) Here's the big issue. My poor unidentified cactus was beginning to rot. Internet research told me to cut out the rotten bits. When I went in for the surgery, however, I found that it was neither rotting from top-bottom or bottom-top, rather right out from a midway point.... The roots seemed fine, still held the earth and were firm, and the top is still it's handsome shade of green, so I cut out only the rotten bits. I'm worried I did the wrong thing. The wound is dried up now, but the flesh around it is beginning to sag. Could this simply be structural? Did I jump the gun? I've been thinking maybe i should just chop him in half, discard the problem mid-section, and try to revive the two halves. Please let me know what you think my best option here is. I really appreciate all your help. You guys are awesome, I'm so happy I finally joined up here.
