what part is the xylem and phloem? is that the stem? it's not tied tight to the stick...the stem is pulling away from the stick so theres room for the stem to grow if it will...am i better off with tape to cover the cracks in the stem so it wont get infected? ive had breaks before but never on one of the main stems...last time it happened on an off-shoot i just stuffed the fan leaves from the broken stem into the rest of the foliage for support and a week later it formed a "knuckle" where the break was...
