I have a yellow Crocosmia which has flowered only once - when originally bought. I split it in two the following year with one part directly into the border and the other half in a terracotta pot. Both gave no signs of flowering last year and both lots appeared to have a lot of dark rusty orange colouring on the ends of its leaves. Is this a disease and, if so, what can I do to prevent it if it happens this summer and how do I encourage it to flower (its foliage is quite rampant in the terracotta pot). I have given both a general purpose feed and an occasional potash feed just recently. Thank you for any advice you can give me. Jan
These articles will refresh you on the care requirements.
The article on the website states to keep the fresh-cut stems in 100 deg F for 48 hours - how do you keep water at 100 deg F?
You would use the warm water as you cut the flowers, then place in a dark location. Yes, the water temp will change.
This is a common technique used with cut flowers.
Also adding a floral preservative to the water will aid in cut flowers lasting.
can crocosmia be pot-planted indoors in Zone 6 in July or August, then moved outdoors the following Spring?
This article will help you.
Can Crocosmia be planted in the ground in zone 7 in the middle TN, Nashville area?
Crososmia is hardy in zones 5 through 9, so you're right in the sweet spot! They should be perfectly fine in the ground. You can read more about crocosmia care here:
y daisies wanting to take over. Thank you. Janette
Early spring is the best time to lift and divide these bulbs.
Not many flowers and leaves laying on lawn
These fact sheets suggest leaving the evergreen foliage to protect plants from frost. But the flowering stems can be cut to the ground when flowering is finished in late summer/fall.
I planted some dry, wizened Crocosmia corms last year, but only the largest corm showed any growth. Its sprout looked like a blade of grass about 6”-8” long. A man trod on the young foliage, and it did not sprout more last year. It is now mid-March, and though other plants are putting forth green shoots, I see nothing from the Crocosmia. Do you think it stands a chance or shall I try to start afresh? Since there are no sprouts, I have nothing to show you.
If you don't see new growth by June, you have lost that crocosmia and need to start again.
