Experienced flower growers dig a hole and put an ordinary street thermometer in it to determine the appropriate planting date for the current year. It is not recommended to plant gladioli very early. In cold and wet soil, the bulbs will begin to rot. But you shouldn’t delay in planting gladiolus either: Flowering will be belated, and the flowers themselves will have to be watered more often and more abundantly.

The easiest and most accurate way to find out when to plant gladiolus bulbs is to ask local flower growers about it.

Location for planting

Plant your gladiolus in a sunny spot, sheltered from the wind, and they will show themselves in all their glory. In the southern regions, a light half-shade is acceptable: Sheltered from the scalding sun, gladioli will stand out in all their beauty longer in a flower bed. But you should not plant them in the same place for several years in a row — it is advisable to change the site annually.

Eliminate moisture stagnation, even short-term, and do not bring in fresh organic matter for planting. However, adding sand to the bottom of the planting hole can protect the corms from rot. Loose sandy or loamy soils with a slightly acidic reaction are ideal.

Planting in full sun in drained soil

It is not enough to choose the right gladioli planting dates to have a beautiful gladioli season, and even by a certain date. It also matters how the gladioli were planted and how the place was prepared.

Gladioli prefer sunny places and do not like stagnant moisture. How to grow gladioli? You need to monitor drainage and soil fertility. Ideally, a flower bed for planting these flowers should be prepared in advance: Mix equal parts fertile soil and sand. Sand should also be poured into the grooves under the bulbs in a layer of up to four centimetres. This will create additional drainage and protect the corms from rotting.

How deep to plant gladiolus bulbs

In addition to the timing of planting gladioli, the depth of the bulb affects the time it takes to flower. This is calculated based on the size of the planting material and the type of soil. So, on rich black and loamy soils, the corm should be at a depth of about 10 centimetres; on sandy soils, it is permissible to plant the corm at a depth of 14 centimetres. How deep to plant gladioli bulbs? The smaller the bulb, the less depth it needs.

The second crucial value is the distance between the bulbs. If they are planted too close together, then the plants will begin to compete with each other for nutrients, and this will affect the size of the flowers. For bulbs with a diameter of 4 centimetres, the optimal distance from each other is 20 centimetres. Small bulbs can be planted at a distance of 10–12 centimetres from each other.

How to plant gladiolus bulbs

To plant a gladiolus, it is necessary to make recesses based on the scheme:

  1. Trench: the distance between the bulbs is 15-20 centimetres, the gap between the trenches is 30-40 centimetres.
  2. Holes: the distance between the holes is 15-20 centimetres, and the distance between the rows is 25-30 centimetres.

It is recommended to pour sand at the bottom of the hole or trench, which will protect delicate roots and bulbs. It is enough to pour a layer of sand 2 centimetres thick. And after you place the planting material at the bottom, you need to pour a little sand on top again, and then the soil.

In pots

Gladioli feel great outdoors, so they can often be seen in gardens. But they also grow well in pots. A distinctive feature of these plants is the long flowering period. Therefore, they are great for decorating balconies, verandas, private houses, and flats.

In the Ground

Regardless of the number of buds, diameter, or colour, gladioli always look luxurious in a flower bed. Shades typically depend on the intensity of the light and the acidity of the soil. To prevent gladularia from becoming tasteless, do not use many different shades. For a flower bed of gladioli, combinations of two to four colours are suitable.

How to care for gladioli

Caring for gladioli is not hard. You just need to water the plants from time to time, gently loosen the soil around the bushes, and weed the area.

After planting, as soon as the height of the sprouts reaches 10–12 centimetres, mulch the base of the plant with tree bark, sawdust, humus, or straw. The layer of mulch should be about 5 centimetres thick.

Tall flowers provide support for growth and development.

Watering should be carried out in the morning or the evening, bringing water directly under the root every week. Moisture on flowers and buds can ruin their appearance.

Do gladiolus spread?
