Ornamental, Allium - plants, care and propagation by seeds: plants

From a romantic country house garden to modern landscaped gardens, Zierlauch has conquered a box seat with beautiful ball blossoms. In order to fulfill the creative hopes perfectly, it is essential for a professional cultivation. Do you still have questions about planting, caring for and multiplying Allium through your head? This manual will familiarize you with the correct procedure in a detailed and practical way.

planting time

From September to November, the time window is open to plant allium bulbs. This appointment has the advantage that the tubers in the sun-warmed soil can root well in time for the winter. Early-flowering garlic, such as the variety 'Purple Sensation', tends in mild winters to expel prematurely. In this case, choose a planting date as late as possible in November to protect the plants from the risk of frost.

Location and soil condition

Ornamental is the sunbather within the multi-faceted Allium genus. The richer the light output, the more magnificent the ball flowers shine with the sun. To match the sun-drenched location, Blumenlauch wants a well-drained soil. As with all bulbous flowers, an excess of moisture is associated with the risk of rot. This is how the ideal location should be:
  • Sunny and warm
  • For high-growing varieties like a wind-sheltered location
  • Nutrient-rich, humus-rich soil with a slight lime content
  • Ideally sandy-loamy and fresh to dry
These site criteria indicate that ornamental onions feel particularly well cared for in the sun-drenched rock garden and pebble bed. This preference distinguishes flower oneness clearly from popular ones, like the shadow-loving bear leek.


Ornamental - Allium

To give you pleasure for a long time from your noble ornamental garlic, prepare the soil before planting expertly. Ideally, you dig deep into the ground and remove weeds, old roots and larger stones. The looser the garden soil, the easier it is for the roots to gain a foothold there before the winter. After preparing the soil, put the onions in the soil. How to do it right:
  • Dig a pit that is twice to three times the diameter of the onion
  • Place a 3 to 5 cm high layer of sand on the bottom of the pit as drainage
  • Enrich the excavation to one third with compost and a handful of horn shavings
  • Individually place the onions of Allium in twos or threes in the planting hole with the pointed tip pointing upwards
  • Fill up with the enriched soil, press down with hands and pour
If you want to integrate ornamental onions in small groups into the design plan, create further planting holes at a distance of 20 to 25 cm. For an area-wide planting, plant 24 to 26 bulbs per square meter.
Do not be irritated if the onion tip is not recognizable at first glance. Unlike other flower bulbs, such as tulips or daffodils, Allium can hide the small lobes under the shells. Examine the tuber carefully. Ornate onion bulbs are the most common cause of missed flower festivals.
Tip: Mark the planting location of the onions with a small wooden stake. Thanks to this prudence, next spring you will know where your ornamental sprout will sprout. Above all, late flowering Allium varieties are often unearthed by mistake.


Properly planted in the sunny, sandy-loamy location, the maintenance program is kept to a minimum. In dryness, gently water ornamental corals without causing waterlogging. Best time is early morning or in the evenings, when no sunbeams hit the plant. Whether or not there really is a need for casting is easy to determine with the help of a finger test. To do this, press your thumb 2 cm deep into the ground. If you feel no moisture here, the plant would like to be watered. Place the normal tap water directly on the root disk.
By placing compost and horn shavings in the planting hole as part of the planting, the nutrient requirement for the first season is covered. In the following years, in the autumn, you work mature compost with horn shavings into the soil and water it. By the beginning of the next growing season, vigorous soil organisms have processed the nutrients to the extent that they are available for the plant and stimulate growth. If you missed the autumn fertilizer appointment, in the early spring, you administer an organic liquid fertilizer, so that your ornamental spring has enough power reserves for a picturesque flowering period.

To cut

Part of the uncomplicated care program is the pruning.Only when ornamental garlic has fully absorbed its stems and leaves, cut off the plant near the ground. In winter-gray regions it is advisable to use the dead plant parts as natural winter protection and to lay the pruning back to February. The withered flowers can either be cut off immediately or only in late autumn to enjoy the decorative seeds until then or to use the seeds for propagation.


Ornamental - Allium

Ornamental Lily is equipped with a reliable frost hardiness. After the flowering period, the perennial gradually absorbs its aboveground plant parts. Well protected in the soil, the onion survives the winter unscathed. Only in the planting year, we recommend covering the bedding area with leaves, compost or brushwood before the onset of winter. From the second year Allium is so vitally rooted that additional winter protection measures are not required.
Tip: Has the selected planting distance proved to be too short after a few years? Then dig out the affected Allium bulbs after pruning in autumn and put them back in the ground.

Multiply by seeds

The common propagation of ornamental onions is done with bulbs, which are cut off from the onion and used in the bed. Often, gardeners can not make friends with digging up the flowering perennial and trafficking with the knife. With regard to the myriad of seeds, the desire to multiply Allium by seeds is near. The generative form of the offspring succeeds either by direct sowing or on the windowsill. It is important to note in this context that ornamental-seed seeds are cold-germs. Both methods are described in more detail below:

Harvest seeds

To get the seeds, leave the withered flowers in the garden. Over time, capsule fruits that contain black seeds form. Just before the fruits open, pick them off. The seeds dissolve out of the capsule shells by rubbing them between the palms over a plate. Last but not least, the kitchen sieve separates the chaff from the seeds.

direct sowing

The immediate sowing of seeds in the bed is the simplest method of generative propagation. The best time is in the fall so that the seeds get the necessary cold for germination during the winter. How to proceed step by step:
  • Prepare a fine crumbed seedbed in the sunny spot
  • Using the inverted stem of the rake, make a 1 cm deep furrow
  • Place 1-2 seeds at a distance of 10-15 cm into the furrow and seal with soil
  • Irrigate the seedbed with a fine shower
To protect against unwanted guests, such as birds and rodents, cover the bed with a tight mesh. For the remainder of this year's season and next spring, weeding regularly so we do not overgrow the seedlings.

Sowing behind glass

Ornamental - Allium

To avoid the imponderables of direct sowing, you can sow the fresh seeds on the windowsill and grow them into vital seedlings. As part of a stratification, the seed undergoes a cooling phase near the freezing point, whereupon the germ inhibition is overcome. Put the seeds in a wet pouch with moist sand. Keep tightly closed the seed bag in the vegetable compartment of the refrigerator. After about 6 weeks at constant temperatures between 0 and + 4 degrees Celsius, the seeds are ready for the next step of propagation. Every now and then take a look in the bag to sort out germinating seeds. This is how it continues:
  • Small pots fill with potting soil
  • In each pot, press 1 to 2 seeds 1 cm deep into the substrate
  • Use already germinating seeds with the tip upwards
  • Sprinkle with water from the hand sprayer
On the partially shaded windowsill, keep the soil slightly damp. Only add the first liquid fertilizer to the irrigation water if the seedlings have 4 to 5 leaves. In April or May, you will be planting your pupils in the sunny field, as explained in the beginning of this guide.

Diseases and pests

You will not have to complain about classical plant diseases in ornamental onions. Sometimes aphids make their way over the juicy stems and leaves. Therefore, from the beginning of spring, regularly check the foliage on the upper and lower sides to see if any pests have settled here. In the early stages put an end to the plague with the proven soap solution. Dissolve 30 to 40 grams of pure curd soap in 1 liter of water and add another dash of spirit. Spray the infected plant every 2 to 3 days until no lice are found.
