A: I have some alliums that I would like to relocate to a bed of other alliums that are flourishing outside. Do I have to wait until September to do that, or can I do it now?
A: Alliums are summer-dormant bulbs that blossom late in the spring. These can be moved, and the best time to do it is just as they start to fall dormant after finishing their blooming cycle.
I’d hold off at least until the leaves begin to turn yellow. That indicates that the majority of the bulb’s “recharging” is complete. The foliage’s function is to absorb sunlight and create the plant sugars that the bulb stores to grow and bloom the following year using water and chlorophyll. If you remove the foliage too soon, this recharge will be interrupted.
The drawback of waiting until fall is that you won’t be able to pinpoint the location of the bulbs. The foliage will have withered and become brown at that point. You could therefore mistakenly dig into the bulb and kill it if you don’t label the location.
You can find the bulbs by digging just before the foliage entirely turns brown. Dig up the entire bulb and plant it again right away in the new site at the same depth (preferably, around two and a half times as deep as the bulb’s length). Before transplanting, remove the foliage. No immediate requirement for fertilizer or irrigation.

Can bulbs be moved while they are still growing?
Yes, you may wait until the end of the growing season in the fall or the beginning of the spring to move misplaced perennials and bulbs. Why then wait? While they are in bud or even in bloom, many perennials, anything with fibrous roots, and practically any bulb can be moved.
If possible, transplant on an overcast day for the best results to prevent the plant from losing moisture from its leaves to the sun. If the weather can’t wait, transplant in the late afternoon. Down this manner, the plant won’t be stressed out by a day of sun and may start settling in.
The most essential component for creating by shovel is obviously something you already have—water. No matter how carefully you dig, you’ll still cut through some roots because those are what supply the plant with water. The plant won’t be able to get enough water to prevent wilting until they get comfortable in their new location. The answer? Every step of the route is watered.
How well do alliums transplant?
Post-bloom maintenance for alliums is quite simple. Simply continue to water the plants sparingly until they start to shrivel and turn yellow. At this point, you have the option of either dividing the plants or cutting them all the way to the ground.
Divide allium bulbs every three to four years. Simply use a shovel to dig around the plant and lift the bulbs out. You should see a group of bulbs that you may gently separate with your hands. Replant a few in the same location, and immediately transplant the others to different sites.
It’s considerably simpler to take care of allium bulbs that you don’t wish to divide. When the foliage starts to fade, simply trim it back, and in the fall, mulch the soil with 2 to 3 inches (5-7.5 cm) of material. In the spring, remove the mulch to allow room for fresh growth.
What occurs if I sow allium in the spring?
QUESTION: When is the best time to plant alliums? I didn’t plant my onions and garlic in the ground as usual in the fall. Norma G.
Don’t worry, you can plant all of your alliums in the spring just like you can in the fall. Your alliums’ potential size won’t be the same if you plant them in the spring. Instead, employing the spring planting method will result in excellent, slender-necked bulbs topped with vibrant greens. Here are the directions for springtime planting of chives, green onions, onions, and garlic.
Planting Onions in the Spring
Onions can be planted in the spring either as sets or by sowing the seeds indoors in advance. While the weather is still cool, prepare to plant onions in the outside garden. Until the weather warms up in the spring, the onions will rest in a dormant state. Their signal to begin growing seriously is that.
Plant your seeds in the garden as soon as the earth is warm enough to work in areas where the winters are exceptionally chilly. This typically occurs in March or April, near the start of spring. Look up the weather prediction in advance. When planting your onions, you should choose a day when the temperature will remain above 28 degrees Fahrenheit.
You must plant the seeds six weeks prior to transferring the sets of onions to your garden if you choose to grow your onions from seeds rather than sets. From the date you choose in the preceding sentence, count backward. The seeds should be stored indoors, in a dry, secure area, at room temperature. In order for onion seeds to sprout, the environment in which they are sown must consistently be warmer than 50 degrees Fahrenheit.
My allium bulbs need to be dug out soon.
Under ideal conditions for growth, enormous allium bulbs will proliferate quickly, which can cause overcrowding and a loss of vigor. Fewer or smaller blooms may suggest that a bunch of established gigantic alliums needs to be divided sooner even though it usually takes several years for the bulbs to grow congested.
Alliums can be moved in the spring. The best time to raise and divide the bulbs is in late summer, when the ground has dried up and the leaves and flower stalks have entirely withered away. When the smaller, newly formed bulbs are ready, remove them and plant them in nursery pots or in a different bed.
Can I move bulbs in the early spring?
Although bulbs are typically transplanted in the fall, you can also transplant them in the spring. As soon as the ground is soft enough for you to dig them out in the spring, if at all possible, transplant your bulbs, especially if they have spring blooms. If you transplant your bulbs in the spring and they don’t grow or bloom that spring or summer, they should the following year.
If you didn’t do it before in the fall, remove all the old foliage. Leave any newly sprouted leaves on and transplant the bulbs with it.
Depending on the type of plant and how long it has been since it was planted, determine how deep the bulbs are underground. Large bulbs like narcissusi are planted 8 inches below the surface, but little bulbs like snowdrops are placed about 3 inches below the surface. Also keep in mind that, especially after several years, the bulbs may be a few inches deeper than when they were first planted.

Using a garden fork, trowel, or shovel, dig the bulbs out taking cautious not to damage them. Dig a little bit further than you thought in Step 2 to find the first bulb of its kind. To take the bulb out of the dirt, dig a circle around the plant and then start pulling it out in various areas. You can use the first bulb’s depth as a guide to estimate how far to dig the others of its sort.
Shake off extra dirt, then use your hands to break up clumps. This is an excellent time to divide the bulbs if you see they are large and connected to other bulbs. Simply use your hands to separate the bulbs from one another.

Plant the bulbs again right away. Keep in mind that smaller bulbs are buried deeper and larger ones are buried closer to the surface. Before planting, incorporate some compost if the soil is poorly draining. Always raise the tip, backfill the hole, and compact the soil to fill in any gaps. Fill the bulbs with water.
planting allium bulbs
If you are planting many bulbs at once, dig a trench instead of a hole for each bulb. To avoid a dotted appearance, I like to plant in good drifts rather than in twos and threes.
In dense soil, cover the bottom of the pit or trench with a 5 cm (2 in) layer of grit (or decomposed compost).
As a general guideline, make sure the hole is at least twice as deep as the bulb, and space each bulb out by at least three times its width. This is roughly 10-15cm (4-6in) deep and 10-15cm (4-6in) apart for small- and medium-sized bulbs (such as “Purple Sensation”). Larger kinds (like “Purple Rain”) require more room because of their considerably larger flower heads and leaves, thus they should be planted at least 20-30 cm (8 in.-1 ft.) apart. For their magnificent heads, giants like “Globemaster” need to be spaced 30-45cm (12-18in) apart.
If you’re working with really heavy dirt, add roughly one-third grit and two-thirds soil to the bottom of the trench or hole to fill it in. After that, cover the bulbs with soil. After planting, use your hands to level the ground.
growing in alliums in a pot
The same depth at which bulbs are planted in the ground should also be used for potted bulbs. With the larger bulbs, this might not always be possible, but make sure that a large bulb has at least 4 cm (1 1/2 in) of compost underneath it. The number of plants will depend on the variety being planted and the spacing, which should be the same as in the ground.
Alliums: Should you deadhead them?
Alliums are drought-tolerant, thus it’s typically not essential to water plants that are rooted in the ground. Summer irrigation is not preferred by plants since it could lead to bulb rot. Alliums planted in containers will require routine watering, but watch out for soggy compost.
Overwintering
Winter cold can be more damaging to plants in pots. to ensure their winter survival
- Place containers in a protected area.
- Place them in the lee of a wall, within a cold frame, or a greenhouse to provide them with some protection from the winter rain.
Will alliums grow further?
The cultural needs for ornamental alliums are quite minimal and they are hardy to zone 4. As long as the soil is well-drained, they can grow in almost any type of soil. Alliums love the sun and thrive when they have access to it throughout the day. They can be left unattended in the same place for years because the majority of them organically proliferate.
Drought-tolerant alliums actually prefer to be grown in dry conditions. They are not bothered by any dangerous illnesses or bug infestations. And since deer and rodents don’t appear to enjoy the taste of onions, whether they are ornamental or not, you won’t ever have to worry about them.
Just keep in mind that alliums can only be planted throughout the fall. Most garden centers have daffodils, tulips, and crocuses readily available, but alliums are less common. The best course of action is to order the bulbs via mail so that they are ready for planting when you need them. In this manner, you can be sure that they will arrive at your door at the appropriate planting time and that you won’t have to go another year without having these lovely, resilient, and bee-friendly flowers in your garden. Some ornamental alliums develop more along the lines of chives, and you plant clumps of roots as opposed to bulbs. This particular allium is typically marketed as a potted plant, and spring may be a better time to buy it than fall.
Location & Soil
Choose a growing site where there will be at least 6 to 8 hours of full light per day because allium enjoys it. Although having healthy soil is advantageous, it is crucial to ensure that the soil is well-draining. In reality, of the two, efficient drainage is crucial in a big way!
When planted in dense, moist soil or in low-lying places that are prone to water retention, allium bulbs can easily rot. Compost should be added liberally to the planting hole for optimal results.
Compost aids in better drainage and gives the bulbs some nutrients as they start to sprout. You can also sprinkle a little sand or small gravel around the bulbs to improve drainage if the soil is overly heavy or clay-like.
When & How To Plant Allium Bulbs
Allium should be planted in the ground a few weeks before your first hard freeze, just like many other fall-planted bulbs. Prior to the arrival of cold weather, it is crucial to give them this time to adjust to the soil. This enables the bulbs to establish a few roots in the soil prior to hibernating for the winter.
Dig planting holes nearly twice as deep as they are wide. For instance, two-inch-diameter bulbs should be buried about four inches deep in the soil. After that, add about an inch of compost to the bottom of each hole before setting the bulb in position by pushing it into the compost.
Finish by putting a 50/50 mixture of compost and dirt into the planting hole. Many gardeners will also place a small amount of bone meal into each planting hole in addition to the compost.
The bulbs will receive more energy from this, which encourages the growth of larger, more vivid flowers. This step is entirely optional because most soils already have sufficient nutrients for healthy flowering behaviors, especially those that have been treated with compost.
Allium In The SpringHow To Plant Allium Bulbs
Early April will see the appearance of allium, with its vibrant green leaf poking through the ground. The plant will continue to expand its foliage as the temperature rises before putting up a single stem to create its bloom. It might happen as late as early summer, although it usually happens in the middle of spring.
Almost no upkeep is required to make the plants bloom. Allium are not only resistant to deer, but they also hardly ever experience pests or diseases of any form. In fact, it is generally known that allium fully repels slugs and aphids from the areas where they thrive.
A little mulch does help the plants by keeping competing weeds at bay. Avoid excessively mulching plants as it can cause them to retain too much moisture. It is not necessary to fertilize plants further in the spring for them to bloom.
In the spring, watering is infrequently necessary and should only be carried out in situations like a drought or extended dry periods. Actually, Allium is more sensitive to overwatering than underwatering.
As the flowers grow to their full size, staking for large kinds could be required, especially if they are placed in a windier location.
End Of Season CareHow To Plant Allium Bulbs
Allium blooms can either be pruned back when they start to fade or left on the stems to dry. In either case, the plant won’t be harmed. The landscape’s appearance of dried flowers is beloved by many gardeners, and if left unattended, birds will come for food.
Till the plant’s leaves is completely decomposed, let it alone. The leaves provide the bulbs with the energy they need to produce blooms the next season. Unfortunately, removing them before they have fully withered back can interfere with the flowering cycle the next year.
Persian Blue is one of the tallest and most exquisite allium kinds, reaching heights of 24 to 36 inches. (For a reference, see the image at the top of the article.)
They will offer significant interest to any flowerbed thanks to their enormous, spherical blossoms and lofty stature. They remain in bloom for years and survive the cold nicely. Persian Blue is a product link.
The word elegant is extremely appropriate for this species, which has glistening white or pinkish flowers that radiate from their stems. Graceful Allium blooms in the late spring and early summer and grows to a height of about 18 inches.
Like all alliums, it is extremely pest resistant and attracts a lot of good pollinators to its colorful blossoms. Link to Product: Graceful Allium
Beau Regard reaches an astounding height of three to four feet. They are difficult to miss in any landscape since their blooms can get as big as softballs or even bigger. The bulbs are well-winterized and consistently put on a good display of color. Link to Product: Beau Regard Allium
