Features of growing ornamental onions – allium

Ornamental slime onion

Allium in Latin it is simply “garlic”. The Romans named this plant this way for its specific aroma and somewhat pungent taste. Decorative onions are unpretentious, they can be planted on any kind of soil, in sunny areas or in partial shade. The only thing that should be avoided is low-lying areas, where rain or melt water has been standing for a long time; for alliums, the permeability of the soil is important. Alliums are great for creating flower borders, they feel good on alpine slides, they get along with other plants. The balls of decorative onions look especially bright if the plants are planted in a group.

For the first time, decorative onions can be propagated and planted in three ways:

  1. Bulbs. The main, maternal allium bulb has “babies”. You can separate them in the fall, when the plant has already bloomed, store them in a dry and dark place in winter, or immediately plant them at some distance from each other. In the case of planting alliums with a bulb, the depth of the hole should correspond to its two diameters.
  2. Seeds. They can be planted in early spring or autumn, the seeds overwinter well even without mulching. But in this case, the mother’s bulb will give “babies” only in the third year. And the plant will be able to bloom only after the same or even longer period. In addition, the seeds of some species of alliums germinate only the next year..
  3. Bulb. Conveniently, the bulbs that have appeared on the mother plant will allow you to grow an allium of the same color and size. But not all bows have bulbs..

Ornamental Onion Seeds

Taking care of decorative bows is very simple:

  • Alliums love soft, breathable soil, so you have to resort to loosening.
  • Weeding won’t hurt until the onions have grown. In order to control weeds, it is advisable to mulch the flower bed.
  • In the spring, allium can be fed with mineral fertilizers, which have a high nitrogen content. In the fall, you should choose phosphate-potassium fertilizers.
  • Ornamental onions tolerate drought well, so they do not need abundant watering. Of course, if it is clearly visible that the plant lacks moisture, in particular, the leaves have become lethargic, turn yellow quickly and the flowering head tilted, then watering is necessary.
  • After the leaves are dry, the bulbs can be dug up to be planted again in the fall, winter, or spring. Ornamental onions do not like excessive moisture, we have already mentioned this when talking about the choice of soil and site, so in a rainy summer, the bulbs can begin to rot.
