Gladiolus // How to Plant, Grow, Harvest, and Store Gladiolus Corms// Northlawn Flower Farm

Gladiolus are grown from corms, and the corm contains all the necessary food and energy to produce a glorious flower spike with up to 20 florets on each bloom. Start by selecting a planting site that receives full sun and has fertile, well draining soil. You can either choose to dig individual holes for your gladiolus corms, or you can dig a large planting area and place multiple corms in that hole. Either way, plant the corms 4-5 inches deep and leave 3 inches of space between each corm. For a truly spectacular display in the garden, I like to plant mine in groups of 7 or more...I think planting gladiolas in masse gives the look of a beautiful living bouquet in the garden.. Once your hole is dug, place the corms pointy side up, flat root side down in the hole and then cover them back up with soil. Once all your corms are planted be sure to water them in well. In a few short weeks the strong and spiky foliage will emerge from the ground and at that time it's a good idea to give them a light layer of mulch to help suppress weeds and maintain even moisture levels during the growing season.
Gladiolus appreciate consistent water. During dry weather, water the plants deeply to supply the equivalent of 1 inch of rainfall per week. If you notice that the blooms are becoming heavy and starting to lean give them a little support by placing a slender bamboo cane next to the stem and use twine to secure the bloom stock to the cane. If you need to support a large section of gladiolas you can corral them with multiple canes and twine encircling the entire planting area.
I personally love to use my gladiolus as cut flowers, and when you use them for cutting you normally avoid the leaning altogether since you pick them before they become top heavy. Gladiolas bloom from the bottom to the top, and for the longest vase life we want to harvest them when the bottom two florets on a stem are open. You should also remove the tip of the flower to encourage all the other flowers on the stem to open in the vase. As lower flowers fade, simply pull them off, and enjoy the new ones that will continue to open.
I also find that it's a nice idea to succession plant gladiolus throughout the growing season so that you can enjoy a steady supply of blooms. So start planting in spring after all danger of frost has past, and then continue to plant a wave every week or two for continuous blooms. Since they take approximately 90 days to mature, count back about 3 months from your first expected frost date and have that day be your last planting of gladiolus corms.
Now let's talk about what to do with gladiolus after they're done blooming. Since gladiolus corms are hardy in zones 7-10, growers in those areas can leave the corms in ground to perennialize. Simply let the plant die back naturally in the fall and then cut it down to ground level once it has browned. It will come back again for you next year with no additional work on your part. However, growers in zones 3-6 should either treat gladiolus as annuals and plant new corms each year, or they can be dug up in fall and stored until planting next spring. In this case, after the first frost, dig up the corms and allow them to dry (cure) in a warm, dry, well ventilated area for 2-3 weeks. When thoroughly dry, remove and discard the old dried up mother corm located at the base of the new corms. You can either remove the tiny cormlets found around the base of the new corms, or use them for prorogation purposes. Once cured, place the corms in mesh bags or old nylon stockings and hang in a cool, dark, well-ventilated location with an ideal storage temperatures of 35 to 45 degrees Fahrenheit. Next spring, simply remove them from storage and replant them.

First time growing Sweet Peas, tried this method, and so far it has worked perfectly 6 little seedlings outside doing great in my Long Island zone 7B. Editing to say very simple so many ppl on here make it seem so complicated so glad I found this video.

[@mssn3166]

I bought this plant at the dollar store. I planted in spring in front of the house. Hopefully it doesn't die. Thank you for all the info!

[@sharonboone7598]

They really grow on their own. I have just started growing them.

[@kimsgarden777]

This year I missed timing of planting Gladiolus. I enjoyed your beautiful Gladiolus instead. :) Thank you for sharing lovely images.

[@jaswindersingh-qi3jl]

Presentation as beautiful as you are ❤

[@robertobobby7646]

Gorgeous blooming gladiola plants.

[@rosemarystanley1363]

Thank you for this video! My daughter and I plant gladiolus every year. We moved to a zone 7 area in fall of 2019. I had no idea to glads we planted last year would come back again. But they did survive the winter, and began to emerge just as we planted new ones this season. We have so many now, since I’m used to treating them as an annual 😄

[@astrisfuentes44]

Que hermosos me puede vender semilla de gladiolos compre en Amazon y me salieron con polilla 😔

[@dyrmo838]

Hello. I planted gladiolus for the first time and I’m currently waiting for their blooms to came to life. Are you saying that I don’t have to pick the bulbs up given the fact that I live in zone 9? Thank you 🙏, have a great day

[@cuevakim]

Thank you for describing what we should do in the different zones. Just what I needed! I’m done 9b.

[@ElderandOakFarm]

I'm doing 3 successions of gladiolus this year in my cutflower garden and landscape. I ordered a bunch of glads this year because of inspiration from you & Nicole @ Flower Hill farm!

[@dkburruss]

Thank you for this!! I was thinking I would not bother with these next year as mine are not that great! You helped me to realize what I need change next year to grow even more now!!!

[@gardengatesopen]

Sunday Glads!! Very nice! 👍

[@ruqiyaa505]

Thank you!! I planted gladiolus for the first time this year as a cut flower using your previous video as guide 😊. Thank you for the updated info. Now I know how to store them.

[@jasminelouisefarrall]

Thank you so much Danielle for this wonderful informative video 🥰 I’m definitely growing some this year 🪴🌺🪴

[@RockinRavenVA]

Perfect timing. Planted glad corms for the first time this year and they should be blooming before too long. Thanks!

[@marilynH66]

Thank for this video. It is very helpful! I just planted few gladiola corms in a big pot.

[@stacylesniewski107]

What a nice compilation of info. I've never grown them but you've convinced me to give them a try. I'll see if I can find any corms still.

I planted gladiolus for the first time this year. I can't wait to see the flowers 😍

[@ningyo3069]

Wished I watched this a few days ago 😅 planted some for my first time this year and have 6, one is almost in full bloom already, wasn’t sure how to harvest them so went searching for a vid like this

[@BLAZE5417]

Thank You, Thank You is not enough for your video. I really appreciate your time; you provided more information than I thought I needed. Example: I'm in Ohio (near Cleveland) which my zone is 5or6. Regardless, I know I'm in an area that I would need the information you provided on how to dry them. So again Thank You!

[@julienrockingham-ip4co]

Thank you

Thnx 😊

[@Ms.Myla.G]

Thank you for sharing, I felt so lost lol

[@joeboudreault2226]

Thank you so much ... this helped a lot. I've also heard elsewhere that bulbs should be planted no more than three times their height of bulb size in the depths of soil ... which could be three or four inches❤.

[@ludkakoscova889]

Great info, thanks a lot!!!! :)

[@LSD209]

You Rock!

[@venezuelarodriguez2523]

I loved your video, thanks . I'll follow you!

Very Informative video Maam. I will plant this year in October ( I am from India!) .. Video helped.

[@DalhiaSun]

I’ve tried growing gladiolus for the last 60 years mine have never been as beautiful as yours. I hope you have listed your sources beautiful arrangement.

[@sherryjimerson3983]

I planted some last year and they were late bloomers. They started blooming this week.

[@leiaflash5055]

I too planted glads for the first time this season and am eagerly waiting the blooms :)

[@allthatfluffnstuffQLDaustralia]

Great

[@jessecapuhl6325]

Thank you for the information!! You were easy to follow and understand. This is my first time getting into gardening and the gladiolus give off such beautiful plants, let alone their flowers. With them leaning so heavily I didn't know what to do. Now that I have more information, I am ready to help these beauties bloom! I have beautiful white and amazing dark purplish-pink ones!! Also, I am getting some bees back ever since I planted the gladiolus, do you have any other fun flower suggestions to encourage more bees to come around?! I love and support my pollinating bees!!

[@firecracker4151]

Beautiful cat tail

[@user-rm4kr2xo7l]

С ними столько возьни, но они такие красивые😍

[@Skc195]

👌👌

[@Ladypeace5250]

I saw video that said plant then 6-8 inches deep. That will help to stop them from falling over

[@susangarland6869]

Perfect timing! After three years of glads not being the colors I ordered, I finally found a source for corms that are true-to-advertised colors, and I was wondering if they could be re-planted instead of being treated as an annual.

[@aongv]

What place?

[@tinalee7650]

I was just wondering today if it's possible to dig them up - I just planted some but want to move them to a different location next year - THANKS!

[@cynthiangai]

Thanks for the video. Quick question: should I continue to water them after the flowers have been cut? Do I cut the stems right after the bloom or leave them until they turn brown? Thanks

[@nelsonviola8328]

I like the cat

[@ghaithradwan3979]

What a great channel I have a question if possible I live in the middle East close to zone 9 in America, I keep planting glads each year in the ground in fertil soil and full sun location but I hardly get any blooms only green growth. is there something that I am doing wrong or it's just too hot for the plant to produce flowers. Thanks a lot ♥️♥️♥️

[@coloradotulips]

Hi Danielle, I thought you might be interested in a study published last year about thrips resistance in gladiolus. Result: of 14 varieties tested, the best were 130x more resistant to thrips than the most vulnerable. Best varieties: alba, robinetta, live oak, and green star. Most attacked: Charming and Charming Beauty.

[@NorthlawnFlowerFarm]

Fabulous information friend! Thank you so much for sharing this. I will pin this comment for others to see!

[@sarahscott9138]

What is that beautiful push you were standing in front of at the beginning of the video? It looks like what my grandmother used to call a Scottish Rose.

[@MelissaM83]

What are the purple flowers you had on the beginning mixed with the glass? The hummingbird was in one? It looks like what I say is almost a Dr Seuss flower lol I have some and don't know their name!!! I absolutely love them! And they're so important in my garden!!!

[@sans8888]

❤️

[@jerico80]

Shes pretty

[@OfftoShambala]

If you want constant flowers… and you are in the zones where you can leave them in, then they will all bloom at once in the following year, I presume… so you might want to pull up enough to do the succession planting the next year, in those zones. I’m thinking I will start with just enough to leave in and then start succession growing next year and start the practice of pulling the newest ones out to reuse for succession growing.

[@meirosetiger]

My glads spread everywhere in my garden, and they tend to fall down

[@VickyG442]

This was every bit of info I needed. One question. You suggest 4 to 5inch depth and the package says 8. Which should I do?

[@SunlessComa4614]

I've had strong and spiky foliage from my planted bulbs for over a month. I'm guessing the tenderhorn variety stops at that as they've not grown taller, so I suppose I'll plant something with color in front of them

[@Ouinicolemarie]

Not flower related, but I was wondering what microphone you use to shoot your video? I’ve been asked to film a garden tour and I need one and I have no idea where to start.

[@jackiesicilian5720]

Question about planting near a rock water drain area, sometimes it floods and possibly freeze over winter, full sun. Im Going to try planting there, but wonder if CT, zone 7 I think should I dig them up before frost?

[@pinghe9692]

What is the purple flowering plant right behind the gladiolus??? I believe my neighbor has them and I absolutely admire them...!!!

[@carmenbugeja8722]

Thanks for sharing, what size pot would be suitable, do they drop seeds?

[@juliakent2560]

I am in PA and just bought some bulbs... I am trying to figure out when to plant them lol

[@peptopanang5292]

Great video! What camera are you using?

[@mariet4894]

Thanks for sharing I have loads of leaves but no flower stocks on my Glads and they have been planted under cover in March. We’ve had dry weather lately could it be because of this or maybe just too early still?

[@NorthlawnFlowerFarm]

Hi Marie! I would not worry. No bloom stocks here and I planted the first wave in late march. The blooms come right at the end. I would imagine you should see blooms by the end of june. A few varieties are longer - some I've seen at 120 days.

[@myrnaingotangreene7379]

I really like gladiolus, what months good to plant.
