- to skip on cutting down a tree and atracting attention how can i poison it to kill the tree without the poison spreading to my plants in close proximiny.

-i know its a question asked over and over but i cant find a straightforward answer, when guerilla growing in a fairly ideal outdoor enviornment how often should i water.

-how many days can i wait after a rainfall to water again.

-would leaving my plants alone and just watering them in severe drought be possible?

-how early should i top my plant.

-If there is an extremely large amount of roots in the soil should they just be cut out and mixed in with the soil? will they hog water from my plants?
