Do Allium Bulbs Multiply?

Many people have a lot of questions about allium bulbs. Do they multiply? What type of soil do you need to plant them in? What sorts are best for certain climates?

There is a lot that goes into caring for these plants, and it seems like the more we try to answer one question, the more questions arise! In this blog post, I will answer some common inquiries about allium bulbs so you can care for them properly.

Do Allium Bulbs Multiply?

Yes! Alliums reproduce by creating bulblets on their flower stalks or from their bulbils at the end of each flowering stem. This reproduction happens most often when conditions are favorable with plenty of water and rich soils, which allow them to grow quickly. While the bulblets are not as large or strong as their parent bulbs, they can be separated and replanted in another area of your yard for more flowers next year!

How Quickly Do Allium Bulbs Multiply?

Alliums multiply quickly, especially when they are given favorable growing conditions. I tend to see them germinated within 2-3 months, while it takes roughly a year to flower. They can double in size every year if planted in the right place and cared for correctly!

How To Make Allium Bulbs Multiply Quicker?

When planting allium bulbs, choose a spot with rich, moist soil and full sun exposure. While they can handle some shade or dappled sunlight throughout the day, it is best to plant them in an area where they will have access to plenty of sunshine so their flowers grow big and strong!

Doing this will give your allium bulbs the best chance of growing fast and multiplying in no time at all!

Which Allium Bulb Types Multiply the Best?

All types of alliums multiply quickly when given proper care. However, there are certain varieties that excel at multiplying faster than others depending on your climate zone, as well as how much space you have for planting.

If you live in a colder climate zone where frost comes early, try growing ‘Early Giant’, which blooms very early before other plants come out of dormancy! For warmer climate zones, ‘Purple Sensation’ is a good choice because it can handle heat and humidity better than other varieties.

If you live in the southern part of the United States where alliums are lush year-round with no frost to worry about, growing any type will give you beautiful flowers! All types grow quickly regardless of climate zone or location.

So if your garden has full sun exposure for most of the day but doesn’t get too much water during dry seasons, planting an allium variety that grows well in those conditions will be best for making them multiply more easily.

When Should I Divide Allium Bulbs?

It is best to divide allium bulbs when they show signs of being smaller and overcrowded. There are two ways you can go about dividing your allium:

Separate and replant bulblets after flowering has finished. Separating them from their parent bulb makes it easier for the plant to focus on growing one strong flower rather than splitting energy between multiple flowers!

Sift through old foliage, remove dead stems, and use a sharp knife to cut apart young offshoots attached directly to the main bulb so each little bulblet has its own small section of root system underneath it, which will allow it move forward with healthy new growth next season without getting too overshadowed.

Do Allium Bulbs Multiply Quickly in Different Types of Soil?

Allium bulbs can be planted and grown in a variety of soils, but they do best when given rich, moist soil. If you live in an area with clay or rocky soils where it is hard to grow anything at all, try growing them on the edges of your garden beds instead. Planting them around the borders will give them more room for growth without putting too much pressure on your other plants!

How To Care For Allium Bulbs After They Multiply?

Once bulblets have formed at the end of flowering stalks and started to turn green (usually after they flower), gently pull off each one with its roots attached and replant it elsewhere in your yard for next year’s flowers.

Allium bulbs multiply quickly and easily, so you can spread them around your yard quite a bit before they start to crowd each other out! Just make sure that soil conditions are right for all of them where you plant them next year – otherwise some will not grow as well as others.

After replanting bulblets one last time in the fall, store any remaining ones indoors over winter to keep healthy for planting again next springtime!


In conclusion, all alliums multiply quickly. They produce bulblets on their flower stalks or from the end of each flowering stem, and these can be separated easily to grow in another area of your yard! Although they are not as large or strong as their parent bulbs, you should still separate them when replanting for more flowers next year.
