How - to : ready ContainersContainersare excellent when used as an ornamental feature , a planting option when there is slight or no soil to plant in , or for flora that require a dirt type not obtain in the garden or when soil drainage in the garden is inferior . If grow more than one plant in a container , verify that all have similar cultural requirement . prefer a container that is deep and large enough to allow root exploitation and growth as well as proportional balance between the fully developed works and the container . Plant big container in the property you stand for them to bide . All containers should have drainage hollow . A mesh filmdom , broken Henry Clay pot pieces(crock ) or a paper coffee filter placed over the hole will keep soil from washing out .

Problems
