Do gladiolus bloom all summer
Plant Care & Growing Guide
If your previous exposure to gladiolus plants consists of a few stalks leaning this way and that in the flower garden, give this summer bulb, technically called a corm, a second chance. A mass of two dozen or more gladioli in bloom creates a garden spectacle of spiky blossoms, with some left over for your floral arrangements.
A member of the Iridaceae family, plants in the genus Gladiolus also go by the name flag flower and sword lily. Fast-growing gladiolus plants are a smart choice for gardens where space is a premium; they grow to from 2-5 feet tall, adding drama to the border.

Gladiolus Care
Gladiolus plants produce trumpet-shaped flowers that open from bottom to top on a sword-like stem, adding drama to the landscape and bouquets alike. Hybridizers have expanded the color palette so that few flowers rival it, short of bearded irises. One color you won't find in the glad flowerbed is true blue, although plant purveyors try to persuade consumers with lavender plants bearing monikers like "Blue Moon." Many modern varieties have ruffled or frilled petals, adding to their appeal.
As annuals, the root system is limited, giving it a small footprint for the vertical accent these plants deliver.
Even balcony gardens can accommodate a dozen gladiolus corms in a container.
Move over, cosmos: Gladiolus flowers make excellent vegetable garden companions. The flowers attract pollinating insects to increase those tomato yields, and the bold blossom colors won't get lost between your rows of beans and squash. Plant gladiolus corms in the gaps where you've yanked out faded spring veggies like peas and lettuce.
Gladioli look ungainly when they aren’t in bloom, but you can hide their awkward phase in the flower garden. Another strategy is to plant glads behind medium to tall plants that will come into bloom when the glads are finished, like zinnias or dahlias.
Keep your glads off the ground by staking them with half-round plant stakes, hoop stakes, or single stem supports, depending on how many glads are in your grouping.

Light
Gladiolus do best in full sun, but if it's not available they will still flower in partial shade.
Soil
Any well-draining soil is fine for growing gladiolus bulbs. Although glads can tolerate shallow planting, placing them at least 6 inches under the soil’s surface provides support to emerging shoots.
Water
After initial planting, water well. Then, water gladiolus weekly.
Temperature and Humidity
Planting glads too early won’t reward you with earlier blooms: Gladioli pout in cold soil, and may even rot. Wait until night temperatures reach 60 degrees Fahrenheit before you set out your gladiolus bulbs, choosing a spot in your garden that receives at least five hours of full sun each day. Gladioli bloom from July until frost. However, the plants don’t bloom continuously, so planting new corms every two weeks will extend the blooming season.
Fertilizer
Fertilize newly emerged gladioli shoots with a balanced, 10-10-10 liquid fertilizer.
Symptoms of Poisoning
Humans who ingest gladiolus corms may have mild stomach upset.
Livestock and pets may experience nausea, diarrhea, salivation, and lethargy. Call your veterinarian immediately if the animals in your care have consumed corms.
Gladiolus Varieties
- 'Atom': Red with picotee white border
- 'Boone': Yellow with coral accents; said to be hardy to zone 6
- 'Green Lace': Ruffled chartreuse blooms
- 'Lucky Star': Unusual for its fragrance; white with red throats
Pruning
Pinch back dead flowers after they wither. When plant is done blooming, cut back the bloom with gardening shears to ground level unless you plan to dig and store your bulbs.
Propagating Gladiolus
Start with premium sized gladiolus corms, which produce more blooms on heftier stalks. While you can get bargain bags of 10 centimeters glads for a reduced price, springing for 14-centimeter corms is a necessary first chapter of your gladiolus love story.
If the weather is dry at planting time, you can water the bulbs once, but don’t water them again until you see shoots or you may encourage rot.
Overwintering
Gladiolus flowers may perennialize in zone 8 and warmer, but most gardeners treat them as annuals. When first frost strikes, you can dig your glad bulbs for winter storage. Dry them for a few weeks, and store them in a cool, dry place.
Common Pests/Diseases
Thrips sometimes bother gladiolus plants. You may not see the tiny winged insects, but you’ll notice brown foliage tips and flecked foliage. Treat thrips with insect soap.
When do gladiolus bloom? And what to do to for show-stopping flowers |

Wondering when gladiolus bloom? It's no wonder – these exuberant blooms, particularly when planted in swathes, can transform borders with their riotous colors.
But if your gladioli seem to be slower to flower this year, or if you're a first time gladiolus grower, you may be impatiently waiting for them to put on their show.
The answer is fairly simple: gladiolus bloom about 10 to 14 weeks after you have planted them, usually from late June to early July, though you can get them to flower earlier in certain conditions, right through to fall.
Below, we answer your questions fully so that you can work out more accurately when your gladiolus will bloom.
When do gladiolus bloom?
Think back to when you planted your gladioli. This will help you work out when blooms will start to appear.
If you can't remember exactly, it is likely to have been from around March or April.
'From the date you planted your gladioli, count on 10 weeks to get an idea of when they will bloom. They should appear from 70 to 100 days after you planted them,' says Homes & Gardens' Editor in Chief Rachel Crow. 'So if you planted them on April 1st, reckon to start seeing them appear from June 10th through to July 8th.
'And if you have planted corms in succession for continuous color throughout the summer, obviously don't expect them to flower all at once.
'
You can get gladioli to flower faster than 10 weeks. 'To do this, you need to plant corms deep in seed trays in a single layer, keep the soil moist, then put them in a warm greenhouse or propagator. Once they have rooted and shooted, transfer them outside in warm soil.
Why aren't my gladiolus blooming?
There are a number of reasons why your gladiolus might not have bloomed yet, or at all.
- The corms have gone bad: gladioli corms need to be stored in a clean, dry space before planting. Put diseased ones in the ground and they won't produce blooms. The solution is to take care with storage next year and try again.
- The corms were planted too early: put corms into ground that then freezes and you may find they have cracked and become moldy and not grown at all. Next time: plant out after the last frosts.
- They are in the wrong position: gladiolus don't like being flooded or too much shade; your next crop of gladioli need to be in well-draining soil and full sun to bloom.
- The soil is compacted: put simply, if the soil is too dense, the buds won't be able to emerge through it to grow into adult plants that can flower. In future, loosen soil before planting and avoid walking over borders where corms are buried.
- There's a thrip infestation: these tiny bugs will ensure your flowers die before they can bloom. Try neem oil to ward them off before resorting to chemical pesticides.
- Animals have eaten the corms: everything from moles to mice will eat your gladioli corms, so protect them as well as you can with wire netting and other pest control.
- They may be too old: gladiolus corms do produce new flowers year after year, but will eventually run out of steam over time. For this reason, it's wise to keep planting new corms year on year.
- The corms are too small: by next year, with some care and feeding, the corms should produce good growth and blooms.
- They've been overwhelmed by lawn fertilizer: gladioli don't like high nitrogen feed, so if you've been careless with your lawn feed, your plants may not flower. Try feeding the gladioli with a high phosphorus fertilizer to encourage flowers.
How long do gladiolus flowers last?
Gladiolus flowers last around a week, though they can last for two weeks. The lower buds open before the upper ones. This short flowering period is why many gardeners plant gladiolus corms in succession in spring and into summer, usually once every week or two, in order to get a continuous show.

Peculiarities of flowers and types of gladiolus
Gladiolus, or skewer, is a perennial corm plant of the iris family. Elena Vecherina, author of the book Chrysanthemums, Asters, Dahlias and Other Autumn Flowers, reports that 300 BC. e. gladioli grew in the fields like weeds. The gladiolus was a significant flower in ancient Rome. Its name is translated from Latin as ‘little sword’ or ‘sword’. nine0005
What distinguishes gladiolus
Gladiolus flowers are distinguished by various shades. Several buds are formed on the peduncle at once, the number of which depends on the height of the stem. They are strong, medium, small and short. Breeders have already bred two-row varieties of human height, about 25 buds are formed on their peduncles, and 10 flowers immediately open.
The following factors influence the timing and duration of flowering of gladioli:
- varietal affiliation;
- landing time;
- climatic conditions in the region.
Flowering of early varieties of gladiolus begins in late July, medium early and medium late varieties bloom in late August-early September. Late varieties of gladioli bloom in September-October.

Approximately 200 types of gladiolus are grown in cultivated floriculture. Flower growers use wild-growing species for decoration:
- Swamp. A plant with a thin stem 30–60 cm and small dark purple flowers (5–8 cm). It blooms in summer, requires shelter for the winter.
- Byzantine. Frost-resistant species, blooms in summer with purple-raspberry flowers with a white stripe on the main vein.
- Ordinary. The stems grow 60–100 cm, bloom in the second half of spring with small (about 4 cm) purple-violet flowers that form a dense ear.
Cultivated species of gladiolus are also common (hybrid and dwarf varieties):
- Colville gladiolus.
Small-flowered hybrid with early flowering. The height of the stem is 75–90 cm, the flowers are pink, white, rich crimson with white spots. - Dwarf gladiolus. Dutch hybrid with a thin stem and flowers of light colors with a dark diamond-shaped spot in the center. Blooms in mid-summer.
- Gladiolus hybrid. Includes all summer flowering hybrid varieties. Plants 90 to 200 cm tall with flowers 5 to 20 cm and inflorescences up to 20 flowers. Coloring with several shades, strokes and spots on the petals. The edges of the petals are smooth, wavy or corrugated. nine0008
Gladiolus harlem, tubergen, primrose hybrid are also considered popular with flower growers. Daria Buzko in the book "Gladiolus. Cultivation and Care” analyzes the species characteristics of gladioli and emphasizes their varietal diversity, which changes every 20–30 years.

When to plant gladioli
In which month to plant gladioli? In the southern regions, gladiolus bulbs are planted in open ground in late March or early April. In the middle lane, landing is carried out at the end of April and in the first decade of May. For the northern regions, the best time comes in late May or early June.
When to plant gladioli for seedlings? In order for the plant to bloom in a short summer, it is grown in seedlings, planting bulbs in boxes with sand in March-April. At the same time, the time of landing in the ground is taken into account in 3-4 weeks. nine0005
When to plant gladioli outdoors? Gladiolus bulbs are planted in the ground while there is moisture, but they can rot in cold ground. Therefore, it is better to plant planting material when the soil warms up by 10-12 cm to + 8-10 ° С.

How to properly prepare gladiolus bulbs for planting? Planting material must be properly selected and prepared 3-4 weeks before planting:
- select healthy young bulbs with a bottom diameter of 5–9 mm;
- Remove the outer scales from the bulbs and spread on a flat surface with the sprouts facing up in 1-2 layers;
- remove excess sprouts, leaving the strongest;
- place the bulbs in a warm room at least +15°C with diffused light;
- Spread the sprouted bulbs 1-2 days before planting on a damp cloth or sawdust to allow roots to emerge;
- soak the planting material 2 hours before planting in a solution of copper sulfate (5 g per 1 liter of water) or garlic infusion (100 g per 1 liter of water) to decontaminate.
nine0008
Plant the prepared gladiolus bulbs in the ground step by step:
- Choose a site with loamy or sandy soil, low acidity and a drainage layer. The place should be sunny, protected from drafts and wind.
- Dig the soil to a depth of 30 cm, apply nitrogen fertilizer, humus or compost.
- Dig holes so deep that the bulbs are completely buried in the ground. Leave the distance between the pits 15–20 cm, and between the rows -25–30 cm.
- Water holes liberally in dry weather and wait until the moisture is completely absorbed into the ground.
- Sprinkle 2 cm of sand into the bottom of the holes to protect the delicate roots.
- Lay the bulbs on the bottom of the holes, sprinkle with sand and a layer of earth on top so that they are deepened by 7-9 cm.
- Mulch the bed with sawdust, humus or peat.
Plant gladiolus babies in the same way, choosing the planting depth according to the size of the bulbs. Plant the children on a separate bed to get planting material for the next season.

Care of gladioli after planting
For a long and lush flowering of the skewers, use the recommendations outlined in the encyclopedia of garden plants "Landscape Design". Start caring for flowers from the moment of planting:
- Watering. For active germination of skewer leaves in spring and the formation of flower stalks in summer, you will need a sufficient amount of moisture in the garden. If the weather is dry, water the flower beds once every 5 days. For each square meter of planting, use up to 15 liters of water and make sure that the earth is saturated with at least 3 cm of moisture. Water the beds with warm water in the evening, trying not to get on the leaves. For accurate watering, make grooves along the plantings and pour water there from a hose or watering can. nine0008
- Loosening and hilling plants. Gladiolus bulbs in the ground need oxygen. Therefore, loosen the aisles and soil near the bushes after each watering and rain.
Loosening the top layer of the earth prevents the formation of a crust and retains moisture longer. After the appearance of sprouts, the bushes need hilling so that the bulbs do not become exposed when water enters. - Weed control. Weeds steal nutrients from cultivated plants. Therefore, the area where the skewers grow, weed regularly from weeds, removing them along with the roots. nine0008
- Fertilizing. Gladiolus, planted in fertile soil, do not need additional feeding. If the soils are poor, feed the plants during the season: in May-June, apply potash and nitrogen fertilizers, in June - phosphorus, potash, nitrogen, in August - potash and phosphorus. Apply fertilizer at the same time as watering for quick absorption of nutrients by the root system.
- Supports for gladioli. To maintain high flower stalks at the beginning of the season, support pegs are placed on the beds, wire or ropes are pulled. A skewer is tied to them to protect them from falling in strong winds and rains.
nine0008 - Protection against pests and diseases. The skewer has dangerous pests that gnaw the green part of the plant (scoops, naked slugs), damage corms (click beetles, beetles, winter scoops, gall nematodes). Leads to a decrease in decorativeness and death of plants species diseases of bulbous crops: wilting and rot of bulbs, stems, bacterial cancer, mosaic.
Treat plantings 2-3 times a season with fungicides and insecticides as a preventive measure. Also use infusion of yarrow, tobacco, celandine for processing the green part of plants. Sick corms, babies and affected plants are completely removed from the site. Do not plant bulbs in areas infected with specific diseases for several years in a row. nine0005
Gladiolus will become an exquisite flower bed decoration. Choose types and varieties of skewers, plant them at different times, and gladioli will bloom from June until the first frost, pleasing the eye with a wide range of colors.

gladiolus blossoms
gladioli
Gladiolus are the recognized kings of flowers, but their flowering is short-lived. Few flowers can boast a variety of colors, including shades from white to almost black - only gladioli.
In order for the gladiolus to bloom in June, they start trimming the bulbs as early as March. Some of the early varieties of bulbs are planted in individual pots, which must be placed on the window. Water regularly. The bulb will soon sprout and leaves will appear. nine0005
It is not necessary to feed at this time, the supply of food is enough in the bulb itself.
Until the 20th of April, you need to prepare a place in the garden. To do this, you need to warm the bed with a film laid out on it. Growing gladioli are planted at this place.
The day before planting, pour 1.5 liters of hot potassium permanganate solution into each hole. In the future, after planting, care consists of weeding, watering, fertilizing.
10 days after the first batch, the next batch is adjusted, which will bloom in June-July. nine0005
And all other gladioli are planted without preliminary growing - they will bloom in July - August.
In the middle of June you can plant the old, 3rd year flowering bulbs. They will bloom in August-September. Replacement bulbs will not ripen for them, so do not expect planting material from them.
This method was tested in Ishim, Tyumen region.
The well-known breeder Mikhail Alekseevich Kuznetsov says that the flowering of gladioli depends very much on the weather and on the age of the bulb. For example, a large bulb of the second year of flowering blooms about 10 days later than a juvenile bulb grown from a baby.
So by planting bulbs of different ages, we thereby also extend the total flowering time. Note advice from Kuznetsov M.A.: if you plant a large baby of an average flowering period in April, then you can hope for flowering by September 1. nine0005
It is almost impossible to adjust the flowering of gladioli to a certain date, because it is impossible to know exactly how the summer will be - cold or hot - and gladioli are one of the most sun-loving plants. But there are, besides fitting in a pot, some other ways to make gladioli bloom early, not much, for two weeks.
To do this, soak the corms for 15 hours in a solution of trace elements or wood ash. Ashes take 600-800 g per bucket of water. The composition of trace elements per 10 liters of water is as follows: potassium permanganate 2 g, boric acid 3 g, copper sulfate 3 g, cobalt nitrate 1 g, magnesium sulfate 2.5, zinc sulfate 0.7 g. This procedure will improve the nutrition of the corm and speed up flowering for a period of weeks to two.
nine0005
Large-flowered varieties of gladiolus tend to bloom later than small-flowered varieties. Therefore, if you want to admire the flowering of these beautiful plants for a longer time, plant different types of gladioli in your garden, then at first small-flowered varieties will delight you with flowering, and then, at the end of summer and autumn, it will be time for large-flowered medium and late varieties.
