They bloom liberally from early summer through to early fall – and planting out corms every two calendar week is an easy way to stretch their already lengthy unfolding time .
The plants enjoy loamy , well - draining soil with a sandy texture and a slenderly acidic to neutral pH of 6.0 to 7.0 .

If you opt to mature gnome miscellany that top out in the range of a function of 12 to 36 inches tall , pots with a lower limit of 12 inch in diam and height are suitable .
stock varieties grow much improbable , and these necessitate taller commode for a couple of grounds .
The first is that shallow sess make it too soft to overwater the corm , which can chair to root putrefaction and bulb collapse .
Another reason is that marvelous pots are ask to balance the impressive height , which can look top - heavy in little watercraft .
For a visually pleasing look , aim to use container that are roughly one - and - a - half to two - and - a - one-half times shorter than the mature plant life .
For instance , if your plants spring up five to six feet marvellous , prefer a pot that ’s in the range of 18 to 30 in in superlative .
This size avail to anchor the overall appearance and provide a satisfying , harmonious sightline .
Containers can be made ofany type of materialsuch as ceramic , fibreglass , hypertufa , terra cotta , or Sir Henry Wood .
However , if you contrive to winter bulbs in their pots , ensure the material can withstand the low temperatures your realm experience .
Those made from stuff such as ceramic or terra cotta are easily cracked or damage in freeze temperatures .
Also , the pots must have drainage holes to prevent doughy soil – wet soil is a leading cause of bulb rot .
I like to describe the bottom of my garden jackpot with a layer of holey drain fabric to ensure weewee move freely and does n’t impregnate the bottom bed of soil .
A two - column inch layer of broken clayware or pebble exercise well as a drainage layer .
Catchment saucers can be used to prevent water spilling onto deck or patios . you may also use pot toes or stand up to elevate the jackpot to get water run away so the corms stay steadfast and sizable .
Choose a potting dirt rich in organic topic , well - drain with a mettlesome or sandy texture , and with a slimly acidic to neutral pH of 6.0 to 7.0 .
you may apply any good - quality commercial-grade potting soil , but I suggest ameliorate it to improve drainage , nutrients , and cultivated land .
function in one part of organic fabric such ascompost , well - decompose manure , orworm castings .
Add in one part of gritty materials such as landscape gumption , pea plant gravel , perlite , or stone bit to create a sharper texture for excellent drainage .
sword lily are summertime - bloom corms that are sown out of doors starting in mid - spring .
To extend their peak meter , pot up corms at two - workweek intervals until mid - July for continuous flowers all summertime and into capitulation .
send your containers in a full sun location and fill with the amended grime , then meld in one tablespoon ofbone mealfor each corm to kick upstairs strong roots and vivacious bud set .
Nestle the corms into the filth at a depth of three time the corm ’s peak , or about three to six inches deep and space two to four inch apart , with the basal plate , or flat end , down .
Carefully backfill with grease then firm gently over the corms . Water softly to locate the corm in berth .
For taller sort , staking may be need to keep the bow upright . If you prefer for dwarf varieties they wo n’t require extra reenforcement .
Just like gladiolus grow in garden beds , potted care is simple and straightforward .
Feeding
If your corms overwinter in their pots , in other spring before young growth emerges , add a two - column inch layer of constituent materials such as compost , rotted manure , or worm castings as a side dressing .
Work it cautiously into the top two inches of soil with a hand grower .
After new outgrowth emerges , scratch a slow discharge , heyday - supercharge plant food into the control surface of the soil .
Use a expression with lower nitrogen than atomic number 15 to ascertain mess of bloom , not just foliage . Reapply in former summer before blossom starts .

Watering
body of water potted gladiolus regularly , providingone in of waterper week in the absence seizure of rain .
When the top column inch of soil is ironical , water profoundly to ensure the integral ascendant ball is moistened and ward off frequent , shallow applications .
Container plants typically dry out faster than those in the land and in hot weather condition , you may need to water every few days .
After flowering , supervise the soil moisture and dilute watering as needed .
Lightly moist soil is fine , but the corms and origin do n’t care wet pes and wo n’t exhaust as much H2O after the flowers are spent .
Winter Care
After flowering , deadhead the spent bloomsto lineal energy into the corms .
If your gladiola are winter hardy for your neighborhood , the corms can be leave in their throne to overwinter .
But if you ’re in the cooler goal of their hardiness ambit , it ’s a bright idea to move pots to a sheltered country for extra aegis .
internet site such as against a fencing or foundation rampart , a building corner , or tucked into shrubbery are commonly a degree or two lovesome than out in the open .
When the leafage has faded and die off , dilute the stems back to two inch above the ground with blank , sharp shears .
A two- to four - inch layer of winter mulch , such as shredded bark , chopped leaves , or straw applied to the soil surface is also helpful to safeguard bulbs from heaving in freeze / thaw cycles/second .
In area outside of their hardiness reach , corms should be dug up before the first hoarfrost and winter in a frost - free location .
