I have a 10 month old baby avocado plant that I luckily grew from a seed indoors. It is now about 10 inches tall with large green leaves. The problem is I have no idea how to care for this plant or to aid it in its growing process. I haven't trimmed it because I was afraid of cutting it at the wrong spot. I would love any info on what type of soil/fertilizer/steps I can take to help it grow. I try to give the plant as much sunlight as possible but it is winter here and the plant will wilt if I leave it by a window. I know nothing about gardening and would love to get any advice. Thanks!
