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. 

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.

How Long Does Gladiolus Last? | Home Guides

By SF Gate Contributor Updated June 03, 2021

There are more than 10,000 gladiolus cultivars (Gladiolus spp.) with a range of plant sizes and flower attributes. The flowers can be large, medium or small with plain or ruffled petals in nearly any color or combination of colors. Gladioli provide a long season of floral interest both outdoors and indoors. They generally bloom for two months, but this varies depending on the hybrid. There are ways to extend their season both outdoors and indoors.

Gladiolus Hybrid Groups

Gladiolus hybrids included in the Nanus group begin to bloom in early summer. They produce two to three stems or spikes from one corm. The stems grow between 9 and 14 inches tall with three to five flowers open at the same time. Hybrids included in the Primulinus group begin to bloom in midsummer. Each corm produces one stem.

The stems grow to a height of 2 to 4 feet and produce up to 20 flowers. As many as seven flowers may open at the same time. Hybrids included in the Grandiflorus group have the longest blooming season. They begin to bloom in late spring and continue through fall. Their flower stems can be 1 to 6 feet tall with up to 30 flower buds on each stem. Up to 12 flowers may bloom at the same time.

Extending the Blooming Season

The blooming season of Nanus and Primulinus hybrid gladioli can be extended by planting corms every two weeks throughout the spring. They grow and bloom best in organically rich soil that drains quickly and has a slightly acidic to neutral pH of 6.7 to 7. Organic matter such as well-aged manure, compost or leaf mold can be added to improve the soil each fall.

Fertilizer with a 5-10-5 nutrient ratio can be added to nutrient-poor soil just before planting the corms in the spring at a rate of 1 to 1 ½ pounds per 50 square feet, reports the University of Missouri Extension. Where the soil is heavy clay that drains slowly, a raised planting bed can be created for gladioli. A sunny location with a minimum of six hours of direct sunlight is best, but gladioli can be grown in four to six hours of sunlight. Maintain uniformly moist soil until they stop blooming and the leaves turn yellow.

Extending Cut-Flower Life

Gladioli are long-lasting cut flowers, but determining exactly how long they will last in a vase is difficult. Proper cutting, handling and care of the flowers make them last longer. Cut the flowers in the evening or late afternoon when the first two buds change color or begin to open. Use a sharp knife to cut the stem at an angle, and place the cut ends in a bucket or vase of warm water containing flower preservative.

One small packet of preservative per pint of water is the usual dilution rate. Try not to pinch or damage the stems. Four to six leaves should be left on the in-ground plant. Place the flowers in a cool location for one or two hours. Recut the stems at an angle, taking 1 to 2 inches off the bottom. The cut should be made while the stem is submerged in warm water. The flowers should be kept away from cold or hot drafts, and their display water should be replenished regularly.

Lifting the Corms

Even though gladioli are hardy in U.S. Department of Agriculture plant hardiness zones 7 to 10 and can be left planted through the winter in USDA zones 8 to 10, the plants are more vigorous and bloom more profusely if the corms or bulbs are lifted in the fall. Leave them planted until after their leaves turn yellow, but dig them up prior to the first hard frost. The stems should be cut back to ½ inch after the corms are dug up. Wash the soil off, and then let them dry for two weeks.

Remove the old corm from beneath the new corm and separate the small, newly formed cormels. Let the corms and cormels dry for another week. Coat them in an all-purpose fungicide for garden plants, says Missouri Botanical Garden, and place them in a basket or mesh onion bag. They should be stored at 35 to 45 degrees Fahrenheit until early spring. They can be planted up to one month before the last expected spring frost in your area.

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’.

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:

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.

What types of gladiolus to choose

Approximately 200 types of gladiolus are grown in cultivated floriculture. Flower growers use wild-growing species for decoration:

Cultivated species of gladiolus are also common (hybrid and dwarf varieties):

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.

Terms and technology of planting gladioli

In order for gladioli to bloom earlier, it is necessary to take care of the timely and correct planting of corms in the ground.

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.

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 plant gladiolus

How to properly prepare gladiolus bulbs for planting? Planting material must be properly selected and prepared 3-4 weeks before planting:

Plant the prepared gladiolus bulbs in the ground step by step:

  1. Choose a site with loamy or sandy soil, low acidity and a drainage layer. The place should be sunny, protected from drafts and wind.
  2. Dig the soil to a depth of 30 cm, apply nitrogen fertilizer, humus or compost.
  3. 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.
  4. Water holes liberally in dry weather and wait until the moisture is completely absorbed into the ground.
  5. Sprinkle 2 cm of sand into the bottom of the holes to protect the delicate roots.
  6. 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.
  7. 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:

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.

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 is one of the most popular flowers among flower growers, they decorate gardens and flower beds. Lush blooms are located on a long peduncle, they are distinguished by a wide variety of varieties. Consider the flowering of gladiolus after planting, and the proper care of the plant.

Gladiolus flowering time

This plant has another name, skewer, its flowering depends on the planting date, variety, and climate in the area.
An early variety begins flowering at the end of the seventh month, medium varieties - at the end of August or September. Late species begins to bloom at the end of the ninth month. The earlier the bulbs are planted, the earlier the buds appear. You can combine different varieties, and maintain a flower bed with constant flowering until late autumn.

Bulbs should be prepared in March, they are planted in small containers and placed in a lighted place. After some time, shoots appear, while top dressing is not applied, since the seedling takes minerals from the bulbs. At the end of March, the sprouts are moved to an open area, the soil is preheated under the film, and a hot solution of potassium permanganate is poured into the wells.

After a couple of weeks, the next number of bulbs can be planted, after the same time the rest, which is no longer germinated. In June, you can enjoy beautiful flowers, after planting they appear once, the duration of flowering is about two weeks.
When planting last year's bulbs, the plant will bloom two weeks later than young plants. If bushes of different ages are placed, then flowering is prolonged.

Flowering acceleration process

Flowering can be accelerated not only by pre-planting the bulbs, but also by soaking them in wood ash containing trace elements. The composition should include: 2 g of potassium permanganate, 3 g of boric acid, 1 g of cobalt nitrate, 0.7 g of zinc sulfate, 3 g of copper sulfate, 2.5 g of magnesium sulfate.
The plant receives the required amount of nutrients faster to start flowering two weeks earlier than usual. Plants with small flowers produce buds before large peduncles.

How to choose a grade?

When choosing gladiolus, it is better to plant new varieties, as they take root faster in a particular region. It is necessary to purchase plants that are suitable for the area and have high disease resistance.
The choice is made depending on the period of flowering, late, middle, and early species can be placed on the same flower bed, this will extend the period of the flowering area. The early species blooms in early summer, middle and late varieties are released and stored for a long time up to 9buds. It is better not to purchase bulbs of a large, flat appearance, as they have already exhausted almost all the mineral elements. Young material with a diameter of 2 to 3 centimeters and a small height is perfect.

Proper care of flowering plants

Gladiolus needs regular feeding and moisture, as the flowers are much larger than the bulbs, and the root system does not have much branching. Watering is done every couple of weeks, if the weather is too hot, then it is necessary to moisten the soil daily. For a good flowering of gladiolus, moisture should soak the soil to the very bulbs, about two buckets of water are used per square meter, it is poured into special recesses around the plant, which are made in advance. To prevent the plant from rotting, you need to ensure that water does not fall on the leaves and stems.
Loosening the plot is considered a necessary procedure, since after watering a hard crust appears on the surface, which prevents the penetration of air to the bulbs. After loosening, hilling is performed, creating recesses for irrigation. Loosening is performed after rain or abundant moisture.

Mulch can be applied around the plant to retain moisture. Thus, there is no need to loosen the ground, and weeds do not grow under the mulch layer, that is, it is possible to ensure minimal labor and time costs. Peat, compost, humus, needles, straw or grass are used as mulch, the selected material is laid when the bush reaches 10 centimeters.
To prevent weeds from interfering with plant growth, as well as to maintain a neat appearance of the flower bed, it must be removed at an early stage of emergence.

The skewer is not able to feed on its own, so it is important to carry out timely top dressing, depending on the stage of development. The first fertilizers are introduced at the initial stage of development of young stems, during this period a bush is actively formed, and flower stalks are laid. The plant at this time needs nitrogen, but it must be applied to a certain extent, otherwise development will stop and flowering will not occur.
After the bush gains almost full growth, it is fed with phosphorus supplements, at the last stage, when buds appear, potassium-phosphorus elements are added.

Feeding bushes step by step

In order for plants to enjoy a healthy look and lush flowers, it is necessary to perform the correct fertilizing in stages. Thanks to the six stages of nutrition, lush bouquets bloom.

  1. When the first true leaves appear, use nitrogen-potassium elements.
  2. At the stage of the appearance of four leaves, nitrogen-potassium substances and boric acid are added.
  3. When six full-fledged leaves appear, the soil is again nourished with nitrogen-potassium fertilizers.
  4. Fertilization is then carried out when the buds are formed.
  5. After the bush has faded, fertilize the soil again with potassium and phosphates.
  6. At the last stage, watering is carried out with a solution of potassium permanganate.

All elements must be applied in a liquid formulation as they are of no benefit when dry.

Proper planting of gladiolus

Planting of gladiolus is carried out in warm ground up to 10 degrees, this is usually done at the end of the fourth month. If planted early, the bulbs may be stunted or diseased. Plants can be placed in one place for several seasons, the site should be well lit by the sun, in the shade the bushes will not actively develop, respectively, it will not be possible to achieve flowering.

To get a beautifully flowering plant, you must adhere to certain planting rules.
Before planting, the bulbs must be treated with karbofos or potassium permanganate solution, this will help prevent plant diseases. The bulbs are placed in a solution, and left for up to half an hour, for the treatment of children, use formulations of a lower concentration. Then the material is thoroughly washed with tap water, growth stimulants, for example, heteroauxin, can be used.

30 days before planting tubers of early type are placed in a wooden container so that the buds are on top, in one row, and put in a warm place with a temperature of up to 30 degrees. Thus, it is possible to accelerate the time of emergence of buds by two weeks.
Before processing the bulbs in solutions, they remove the husks, the diseased elements must be discarded, they will not give full development.

The bulbs are placed at a depth of three flower diameters, while keeping a distance of about 20 centimeters between the bushes, taking into account the development of the plant. Children are planted to a depth of 3 to 5 centimeters at a distance of about 10 centimeters.
A place for growing gladioli must be prepared in advance, preferably in the autumn when digging up the site. During this period, humus is added, peat, and mineral elements are added. Depending on the acidity of the soil, lime is added once every four years. Humus is introduced in an amount of about three buckets per square meter. If the land has not been prepared since autumn, this can be done in early spring, a month before planting tubers in open ground.

In the third year, the plants must be replanted to another place so that the soil is different in composition, but not detrimental to the plant. The chosen place should be well lit and ventilated, without stagnant water, otherwise various diseases may appear.
Gladiolus feels favorably in slightly acidic soil, if planting is planned on loam, sand, humus, and compost are introduced. Before planting, the site must be dug up, this can be done in the autumn, and loosening in the spring and making a hole.
To create a bed of gladioli, a groove is made, water or phytosporin composition is poured into the bottom, this remedy prevents various diseases. Then river sand is poured, with a layer of about two centimeters, or sphagnum moss is used as drainage. Bulbs are laid out at a certain distance, and covered with earth.

How to cut flowers correctly?

Many people wonder if it is possible to cut flowers during active budding and how to store them for a long time in a vase? From gladioli, you can create beautiful bouquets with a combination of other plants, so that they last longer, you need to cut the flowers correctly.
When cutting flowers, it is necessary to take into account the further correct formation of the bulb, and the appearance of children, therefore, up to four full-fledged leaves are left on the stems. The peduncle must be pierced with a knife, carefully broken, and removed, the leaves will not be damaged. To keep the bouquet fresh for a long time, cut the buds in the early morning, when the first flower blooms.

The container must be filled to the very brim with water so that the cut flowers can take the required amount of moisture, so the buds will retain their elasticity for a long time.
