In addition, some states do not allow certain plants to cross state lines.

There are weeds, which do not allow other plants to come up.

Allow the plant to dry off before taking it back to its permanent place.

These can be trimmed to allow main plants to develop well.

This allows the plant to obtain a great deal of light and air movement.

Allow the plant to rest with no food and little water for about six weeks after flowering has finished.

This allows plants to grow and water to stay liquid.

But Federal officials called that possibility "unlikely," and they allowed the plant to remain open.
