Most perennial may be successfully divided in either spring or drop . Do a little homework ; some perennials do have a preference . How - to : Preparing ContainersContainersare excellent when used as an ornamental feature , a planting option when there is little or no grease to plant in , or for plants that require a soil type not witness in the garden or when soil drainage in the garden is subscript . If growing more than one plant in a container , make trusted that all have interchangeable cultural requirement . Choose a container that is deep and large enough to allow ascendent developing and ontogenesis as well as proportional balance between the fully develop flora and the container .

Whiteflies can undermine a plant , eventually leading to plant destruction if they are not check . They can transmit many harmful plant viruses . They also produce a sweet substance call up honeydew ( coveted by ants ) which can contribute to an untempting black Earth’s surface fungous growth called sooty mold .
Possible controls : keep weeds down ; use screen in windows to keep them out ; take away infest plant out from non - infested industrial plant ; use a contemplative mulch ( aluminum foil ) under plants ( this repels whiteflies ) ; maw with yellow gummy cards , practice label pesticides ; encourage natural enemies such as parasitical wasp in the garden ; and sometimes a good unfaltering shower of water will wash them off the works .

However aphids do produce a honeyed substance call honeydew ( coveted by ants ) which can direct to an untempting shameful airfoil growing call sooty mould .
Aphids can increase quickly in bit and each female person can produce up to 250 alive houri in the course of a month without coupling .
