Plants that will grow in small containers must be opt carefully . The plants should have small rootage systems so they wo n’t be cramped , and they should have diminished flower and leave so they do n’t appear top - great and overwhelm their containers . Almost any kind of container works for a small flora , as long as the container has bottom drain holes and is large enough to hold at least 1 to 3 gallons of pot grime .
Step 1
Several potpourri of annual vegetable grow well in modest containers . Leafy Green River , such as lolly ( Lactuca spp ) , and low base vegetables , including radish ( Raphanus sativus ) , grow well in containers when their soil stay on moist . Dwarf variety show of other vegetable also are suited for minor container . They let in the tomato ( Solanum lycopersicum ) cultivars " Tiny Tim " and " Patio . " veggie plants ask well - drained filth kept moist with even watering .
Step 2
Herbs
Most herbaceous plant grow easily in a promiscuous , well - drained potting mix and do n’t ask as much water as vegetable plant . Each herb plant life needs about 1 gallon of pot soil . So multiple herbaceous plant works can grow in one pot that apply 2 or more Imperial gallon . The good herbs for container are compact rather than tall . Two options are gnome cultivars of basil ( Ocimum basilicum ) and German chamomile ( Matricaria recutita ) , which are both annual herb . repeated herbs for container include English lavender ( Lavandula angustifolia ) , which is sturdy in U.S. Department of Agriculture plant hardiness zona 6 through 9 , and sage ( Salvia officinalis ) , brave in USDA zones 4 through 8 .
Flowering Annuals
Most flower one-year bedding works can be grown in small containers . Just check the plant label when shopping to secure flowering yearbook ' mature size will not flood out your containers . A plant ’s matured size should be no more than three times the plant container ’s meridian . Petunias ( Petunia x hybrida ) , nanus snapdragons ( Antirrhinum majus ) , geranium ( Pelargonium x hortorum ) , dwarf French marigolds ( Tagetes patula ) and fresh alyssum ( Lobularia maritima ) are blossom annuals that can develop in pocket-size containers . Because small containers dry out out more cursorily than larger containers , check the industrial plant ' soil every daytime , and supply water if the territory feel dry to your touch .
Compact Perennials
Some of the perennial plants that grow well in small containers are three - vein everlasting ( Anaphalis triplinervis ) , which is hardy in USDA zone 3 through 8 , and nub - leaved bergenia ( Bergenia cordifolia ) , dauntless in USDA zone 3 through 9 . Both of those works strive 12 to 18 in tall . Low - growing reason covers also act well in a small container and can be paired with a taller perennial if the container is bounteous enough for two plants . Keep perennial works ' soil moist during the growing season . Container - grown perennials should be winter indoors to keep their grime from freezing . A wintertime temperature of 50 degrees Fahrenheit is ideal for most repeated plant life .
