Is it better for me to grow 20 plants in one and the same pot, or just one? Is at hand a plant that is okay near being grown next to a lot of other plants? Is within a plant that would even die because it's with other plants? Please oblige!
Answers:    Plants need nouns circulation around them so they could grow more vigorous. Plants that hold poor air circulation are more succeptable to insects and diseases. Plants should be spaced according to their heigth and girth. However some plants like to be crowded, they will bloom better approaching cannas, cymbidium orchids, and lilly of the nile.
Some plant material bestow off chemicals call alleopathy, these alleopathic plants prohibit other plants from growing around them, this is for thier own survival. Walnuts are a classic example they have an allepathic chemical call juglan.
Another reason why it is not reccomended to crowd plants together is because root will compete near one another for watr and neutrients.
You should not overcrowd. Every plant needs room to expand their roots and if you put too plentiful in one pot/area, you can expiration up malnourishing them because there aren't plenty nutrients to go around.
I'm not sure if near are any plants you can crowd together safely, but I know that you should other leave for a while room to breathe.
