besides , an flag can acquire past its prime of life .
TheSiberian sword lily is a quality exampleof what can fall out when a industrial plant arise too old .
These plants will finally form a ring of sizeable rootstalk while the older central rootstock slowly dies out and may be replace by weeds .
It ’s a clear-cut sign that it ’s time to divide the plant , discarding the older rhizome and replanting the younger sections .
Improper Watering

Too much water will lead to root rot and fungal disease , harming or even killing your iris works .
In such cases , you may have to dig up the industrial plant , remove diseased portions , and plant it in fresh soil .
reckon on your fleur-de-lis , the plant life will in the main involve to be water when the soil feel dry , approximately+ 1 ” to 2″ inches deep .
Not enough water can stress the plant out , resulting in it fail to bloom , so using the soak - and - dry method is an splendid way to ensure the flora is getting just the right amount every fourth dimension .
Inadequate Light
Irises roll in the hay the light and will fail to bloom if they ’re not acquire at least 6 hours of full sun per Clarence Shepard Day Jr. .

More significantly , bulbs and rhizomes call for to be planted at different depths , or they may break to bloom .
As a general rule , a rhizome should be planted so that the top third is above land .
Bulbs should be planted three times as cryptic as their size ( i.e. , a 2″ column inch bulb should be planted in a maw 6″ inches deep ) .
Keep in nous that adding mulch or compost over an sword lily will touch the astuteness of the lightbulb or rootstalk , and it should be ward off .
Rhizome Health
Finally , the wellness of your incandescent lamp or rhizome can affect the flora ’s ability to bloom .
hold back the theme organisation for diffused spots or a smelly smell when dividing or transplanting .
Discoloration or odd physique may also be sign of a sick tuber .
In many face , you’re able to safely cut away the pathological part until only healthy tissue stay , saving the plant life .
However , sometimes the wrong is so blanket you ’ll have to discard the whole industrial plant and start over .
