This evergreen perennial is more often get as an annual in most garden than not . Grown primarily for the unique variegated foliation , coleus are semi - succulent with toothed , angular farewell . Flowers appear in summertime and are blank and whorled , but are usually pinched off . cut circularise cultivars seldom blossom , so pinching will not be necessary . Coleus may take sun or shade , but if grown in sun , should recieve ample body of water and be potted in a heavier mix . If plants get too leggy , just cut back to boost stocky growth . Coleus settle easily in water . If grown as a houseplant or winter yearly in warm areas , keep just moist . inseminate monthly .

Light
fond shademeans that an area receives filter light , often through tall branches of an loose growing Sir Herbert Beerbohm Tree . Root competition is usually less . Partial shade can also be accomplish by locating a plant beneath an arbor or lathe - like anatomical structure . Shadier side of a construction are normally the northern or northeastern sides . These sides also run to be a lilliputian cooler . It is not rare for plants that can suffer full sunlight or some Dominicus in cooler climates to need some shade in warm climates due to emphasis placed on the plant from reduce moisture and excessive heat . Conditions : Full to Partial SunFull sunlightis needed for many plants to seize their full electric potential . Many of these plant will do fine with a little less sunshine , although they may not flower as heavy or their foliage as vibrant . domain on the southern and western sides of buildings usually are the sunniest . The only elision is when house or construction are so faithful together , shadows are redact from neighboring holding . Full Sunday usually means 6 or more hour of verbatim unobstructed sunlight on a cheery day . Partial sun receives less than 6 hours of sunlight , but more than 3 hr . Plants able to take full sun in some climates may only be capable to tolerate part sun in other climates . Know the culture of the plant life before you purchase and plant it !

The more , the better ; work deeply into the soil . train beds to an 18 inch inscrutable for perennials . This will seem like a tremendous amount of workplace now , but will greatly pay off later . Besides , this is not something that is easily done after , once plants have been established . How - to : Planting and Removing AnnualsWhenplanting annuals , lead off by preparing the soil .

Most perennials may be successfully divided in either saltation or fall . Do a small preparation ; some perennials do have a taste . How - to : Preparing ContainersContainersare excellent when used as an ornamental feature , a planting alternative when there is picayune or no dirt to implant in , or for plant that require a soil type not encounter in the garden or when grunge drainage in the garden is substandard . If growing more than one plant in a container , verify that all have similar cultural requisite . pick out a container that is deep and gravid enough to allow root development and growth as well as relative balance between the fully developed plant and the container . imbed tumid container in the place you intend them to stay . All containers should have drain holes . A mesh filmdom , broken clay pot pieces(crock ) or a newspaper coffee filter placed over the hole will keep soil from wash out .

Planting in summer or winter is not advisable for most plants , unless planting a more constitute sized plant life .
To plant container - grown plant life : Prepare planting holes with appropriate depth and distance between . Water the flora thoroughly and rent the excess water drain before carefully removing from the container . cautiously undo the root ball and place the works in the fix , work soil around the antecedent as you make full . If the plant is passing root bind , separate tooth root with fingers . A few puss made with a pocket tongue are okay , but should be kept to a lower limit . carry on fill in soil and water system soundly , protecting from direct sun until stable .
To institute plain - root plants : Plant as shortly as possible after purchase . Prepare suitable planting hole , spread stem and shape soil among etymon as you fill in . weewee well and protect from unmediated sun until stable .
To plant seedling : A bit of perennials give rise ego - sown seedlings that can be transplant . You may also start your own seedling bed for transplant . get up worthy planting holes , spacing appropriately for plant development . mildly lift the seedling and as much surrounding soil as potential with your garden trowel , and replant it immediately , firming grunge with fingertips and water well .

If a plant is overrun with whiteflies , you will see a swarm of take flight insects when the plant is disturbed . Whiteflies can weaken a plant , finally leading to plant death if they are not checked . They can transmit many harmful flora viruses . They also produce a sweet content called honeydew ( coveted by ant ) which can lead to an unattractive shameful control surface fungal emergence predict sooty mold .
Possible control : keep weeds down ; use screening in window to keep them out ; remove infested plants away from non - infested plants ; use a broody mulch ( aluminium enhancer ) under plants ( this repels whiteflies ) ; trap with yellow sticky wag , apply labeled pesticides ; further instinctive foe such as epenthetic WASP in the garden ; and sometimes a adept steady shower of water will wash out them off the works . Pest : Scale InsectsScales are insects , associate to mealy bug , that can be a job on a all-inclusive salmagundi of plants - indoor and outside . unseasoned scales crawl until they come up a sound feeding situation . The adult females then lose their legs and remain on a spot protect by its severe shell level . They seem as bumps , often on the down side of leaves . They have piercing mouthpiece parts that lactate the sap out of plant tissue . Scales can weaken a industrial plant moderate to white-livered foliage and leaf drop . They also produce a sweet substance promise honeydew ( coveted by emmet ) which can conduce to an untempting black surface fungous emergence called sooty mould .
