Iris are an incredibly diverse group of electric light and rhizomes , encompassing over 200 species and numerous cultivar . They range widely in cultural requirements , some are drouth kind , while others demand a pond to expand . Flower colour and size diverge dramatically as well . Foliage is eatage - similar or steel - like , and flowers are complex , very showy . The three inner segments(known as standard ) are petals , the out ones(known as falls ) are sepal . There are three main categories of irises : bearded , smooth-faced and crested . whiskery iris are the most pop and well known , and come in virtually every color .

Where winter temperatures rest above 10F , it is absent or rare . It is a larval form of a moth , the main prevention is a respectable fall garden cleanup of detritus where larva can winter . ‘ Margaret Hunter ’ a Louisiana smooth-faced iris does best in moist soil in areas with hot summertime . The flowers on this cultivar are light violet , ruffled and blooms ahead of time in the season .

Planting
A week to 10 day before planting , add 2 to 4 inch of ripened manure or compost and body of work into the planting situation to improve fertility and increase water retention and drain . If soil composition is feeble , a layer of topsoil should be considered as well . No matter if your filth is sand or mud , it can be better by lend the same affair : organic matter . The more , the ripe ; work deep into the territory . Prepare beds to an 18 inch deep for perennial . This will seem like a wonderful amount of work now , but will greatly pay off after . Besides , this is not something that is well done later , once flora have been established . How - to : Planting BulbsPlant bulbsat a depth that is three meter their height , and at least 1 - 1/2 electric light - widths apart . run a little bone meal fertilizer into the bottom of your yap , and then place the bulb vertical in the kettle of fish . The more pointed end is almost always the top . If you have bother telling which is the top , look for evidence of where a prow or stem were last twelvemonth . If in doubt , plant them sideways . meet in with soil gently , pull in certain there are no rocks or clods that would impede the bulb ’s stem . When plant a great telephone number of lightbulb , dig out an surface area to the specified astuteness , place bulbs and replace soil . This ensures that ground has been in good order prepared and bulb are evenly spaced .
Plant bulbs in rude drifts rather that conventional row : bulbs can fail or be eaten , leaving hole in a schematic arrangement , or will tilt with freezing and thaw . If you have trouble with gophers or squirrels eating your bulbs , sample sprinkling ruby pepper in the holes , incubate the bulbs with chicken - wire , surround bulbs with acute sherd of crushed rock or other substance , or planting rodent - repelling bulbs likeFritillarianearby . How - to : educate ContainersContainersare excellent when used as an decorative feature , a planting option when there is piffling or no soil to plant in , or for plants that require a dirt type not found in the garden or when soil drainage in the garden is substandard . If growing more than one plant in a container , make certain that all have like cultural demand . take a container that is deep and large enough to allow root development and increase as well as relative balance between the fully develop plant and the container . Plant large container in the place you mean them to stay put . All containers should have drainage holes . A meshing blind , broken stiff potty pieces(crock ) or a paper coffee filter lay over the hole will keep filth from wash away out . The potting soil you select should be an appropriate mix for the plant you have chosen . Quality soils ( or grease - less medias ) absorb moisture readily and evenly when wet . If water run off soil upon initial wetting , this is an indicant that your land may not be as good as you think .
Prior to filling a container with soil , wet pot soil in the bag or place in a tub or lawn cart so that it is equally moist . Fill container about halfway full or to a level that will allow for plants , when implant , to be just below the rim of the flock . Rootballs should be flat with soil line when project is complete . Water well . How - to : Planting PerennialsDetermine appropriate perennial for your garden by weigh sun and shade through the mean solar day , exposure , water prerequisite , climate , soil makeup , seasonal semblance desired , and place of other garden plants and trees .
The good times to establish are spring and surrender , when soil is workable and out of risk of rime . pin planting have the advantage that root can rise and not have to compete with developing top growth as in the leap . Spring is more desirable for perennials that dislike fuddled conditions or for colder areas , allowing full organization before first wintertime . Planting in summertime or winter is not advisable for most plants , unless planting a more established sized plant .
To plant container - grown plants : Prepare set holes with appropriate depth and space between . Water the works thoroughly and let the redundant body of water drain before cautiously removing from the container . cautiously loosen the root orchis and place the plant in the mess , working soil around the root as you fill . If the works is exceedingly root bound , disjoined roots with fingers . A few slits made with a sack knife are okay , but should be continue to a minimum . Continue filling in dirt and weewee thoroughly , protecting from lineal sun until static .
To plant scanty - root plant life : Plant as soon as possible after leverage . Prepare desirable planting mess , spread roots and knead soil among origin as you fill in . Water well and protect from lineal sun until unchanging .
To plant seedling : A routine of perennials produce self - seed seedlings that can be transplanted . You may also go your own seedling bed for transplanting . Prepare suited planting holes , space appropriately for plant development . lightly lift the seedling and as much surrounding soil as potential with your garden trowel , and replant it immediately , tauten stain with fingertips and water well . Shade from lineal sun and water regularly until stable .
