Today’s Flower – Gladiolus

Growing perennials means lots of color when you plant gladioli. There is something about a bare piece of ground that suddenly breaks with foliage at an amazing rate and then bursts in a splendid show of flowers a few weeks later.   Gladiolus are not actually bulbs but are considered perennial corms.How to Grow Gladiolus

Easy to Grow Gladiolus Corms Add Appeal to any Garden Setting

I remember having my lunch outside one year watching each day as these beauties kept getting taller and taller.  There was so much anticipation for the flowers to finally appear.  And they did not disappoint!

A corm is a rounded underground storage organ that is present in plants such as crocuses, gladioli, and cyclamens, consisting of a swollen stem base covered with scale leaves. And flowers of course!

There are so many varieties that can be grown and they are easy in most gardens.  I love gladioli because they make spectacular cut flowers and attract bees and butterflies like crazy to my garden.

Here is how to grow them.

  • Plant gladioli corms in the spring after danger of frost has passed.
  • Loosen the soil to about 12 to 15 inches.  (these are tall plants and need a good root system.
  • Add organic matter to the hold and plant the bulbs about 3-6 inches apart and water well.
  • Glads are best grown in a garden that gets full sun
  • Now is the time to stake if you are planting tall varieties, so that you don’t damage the plant with a stake later.
  • Days to flowering is about 90 days.
  • If you like cut flowers, cut the stems when 1 or two flowers are open. The others will continue to open when place in water.
  • Be sure to leave some of the leaves after cutting the flowers.  The corms need them to provide nutrition for next year’s growth.
  • Zones 7 or 8 need just a layer of hay or straw. If you live in colder zones, you will need to dig up the corms, dry them and store them at 35-45 º F until the spring and then plant again.

Here are some of the gladioli blooms that graced my garden this year.

    I planted the bulbs 3 years ago. They’ve yet to all bloom…I’d say out of 20 plus bulbs, we got about 5 flowers this year. They grow, but don’t flower….what am I doing wrong? Please help…

      You could be using the wrong type of fertilizer too. Some promote leaf growth and some are better for flowers.

    My gladiolus just get leaves. This has been for 4years. They have full sun. These are all close together. Do I need to separate them is that why they get leaves.

      Hi Marsha. If they have never flowered, it could be because the bulbs were too small when planted. Larger bulbs give good flowers. If they have flowered in the past, it may be time to divide them. This should be done every 3-4 years. When you dig them up, you may see that the bottom bulb is shriveled and the corm growning on the top looks fresher. Remove the old bulb and dry them and then plant for spring.

      Hope you like them as much as I do Martha. The flowers are so pretty and perfect to bring indoors if you like cut flowers.

    Many years ago I filled an old trough with soil and planted some gadioli bulbs They never fail to give me a show. A few years ago I lifted them and split, the bulbs into two further pots, this year the newer bulbs flowered too.

      I have them everywhere in my yard. I love to see the long tall stalks just before they bloom. Carol
