Grew this avocado from the pit 10 months ago. Planted it into a small pot and then again into this polystirene container. It hasnt seemed to grow at all for about 3 months. The new leaves are starting to look yellow and some main big leaves are full on brown. The seed looks dead (then again maybe it doesnt need to rely on the original seed anymore). I recently covered the seed with soil. The bottom of the young tree looks more like a tree trunk material. Maybe it is, or maybe it's rot? I do not use any fertilizer. Just water ever 2-3 days. I leave it on my balcony. I do leave it out when it rains as well. Never pruned. Is it getting too much sun? It's not placed in a location with a full sun cycle. Should i place it away from rain water? Can't let it die on me. There are holes under the container.
