Q. Caring for Crocosmias

A friend gave me some crocosmia corms, which I planted in my backyard over a month ago. The plants have not produced new growth yet. Shall I cut the existing leaves to promote new growth?

Leave you crocosmias alone and hope for the best. They may have been too old, or maybe they are taking their time. Crocosmias are best planted in the fall, so you may not see much action this year, but may be surprised to see them next year.

If you are in zone 5 or higher (learn your zone here: https://www.gardeningknowhow.com/planting-zones/usda-planting-zone-map.htm )the plant should be fine in winter. Hopefully you have a variety that is hardy in your area. If you wish to keep it in the pot, you could dig a hole and sink the plant and pot into it; that way, the earth will insulate the roots from killing cold. Cover the whole thing with mulch, as you would for plants in a bed.

Q. crocosmia

What is the best way to keep my Lucifer plants/crocosmia from falling over? They are pretty tall and don’t stand up on their own.

There are a number of trellis options available at any local hardware store, nursery or DIY store -- pick a design that will allow your Crocosmia to easily lean against it without getting in the way of the blooms. You can gently tie the stems to the trellis structure as close to the bottom of the plants as possible.

Fencing, bamboo poles, antique ladders...almost anything can be used. Get in touch with your creative side and have some fun when choosing a trellis structure for your Crocosmia!

Q. Keeping Crocosmia blooming

I have a large clump of Crocosmia that has been blooming since June (now July 22), but the flowers on the stalks look like they are just about finished. How can I keep them blooming until fall?

Healthy Crocosmin bulbs will bloom midsummer thru early fall but need optimum growing conditions.
Dead head the flowers if your cutting them for cut flowers.
Here is a link to refresh you on the care and growing requirements.

Q. Crocosmia problem

Most leaves are turning brown. I transplanted from Seattle to Houston last summer. It grew fine and returned in March. Two blooms but now it’s very sad. It’s in a Mexican clay pot facing SW. Any advice please.

There could be a few reasons for the poor growth and lack of flowering.
Make sure the plants are properly watered. In warm weather a container may need to be watered twice a day.
Make sure the excess water is draining from the pot.
You may need to move the container to a morning sun and afternoon shade location so that the pot does not heat up so much during the warmest part of the day.
The plant could need to be divided, when flowering slows down it can be sign that the plant is overcrowded.
Look for signs of disease or pests, do the leaves yellow then turn brown?
These links will help refresh you on the care and help you pinpoint the cause of the issues.

Q. care of crocosmia planted in pots

I live in the Tidewater area of Virginia, zone 7. On April 12, I dug up out of my garden numerous Emily McKenzie crocosmias and then planted them in 3 pots on our deck. Significant green shoots came up and turned brown, but no flowers. I fed the pots with Miracle Grow, kept them sufficiently watered, and one time added vinegar to the water for acidity. I am an experienced gardener and baffled. Should I toss them or is there hope they may bloom next year? Thank you for any suggestions or thoughts.

The plants could have been suffering from transplant shock, a common problem. They will probably come back next year after they recover. Since they are not actively growing now, don't fertilize any more, and water only once they dry out.

Q. crocosmia

After the flower blooms and fades, the sprig gets a long row of little bumpy seed like things. Are these the corms that need to be planted (corms?) or do you divide the actual bulb from below the ground and this forms new plants? Do the bulbs or corms both blossom the next year?

You can cut back the seed heads and stalks, but it is best not to cut back the leaves until they die on their own at the end of the growing season. The plant needs them to store energy for growing and blooming next year.
