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.

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.
When is Allium transplantable?
Taller people can need assistance when exposed. After the flowers have faded, let the plant with them until they disintegrate because they make for wonderful winter interest. Some gardeners collect the seedheads and dry them so they can be used as home decor.
Allium bulbs can stay in the garden for multiple seasons. When planting new plants, try to keep in mind where you already put bulbs to prevent damaging those areas.
How to propagate alliums
In a few years, allium bulbs will grow in number. You may occasionally see the white bulbs being pushed out of the ground. Carefully pull the bulbs and gently peel out the offsets in late autumn or very early spring to replant them directly into the ground.
Allium can be grown from seed by leaving the flowerheads on the plant and harvesting the ripe seed to sow right away. Keep in mind that starting alliums from seed requires patience because it takes years to produce a flowering plant.
Growing alliums: pests and problem solving
A fungus called allium white rot prevents the growth of other alliums and onions. Clear and burn the infected plant material, and stay away from growing alliums in the same spot for at least five years, to prevent recurring infections.
Alliums have a tendency to outgrow their surroundings. Learn how to control the amount of alliums growing in a border in this Gardeners’ World video:
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 are alliums used after they have flowered?
The foliage of the allium often appears at least a month before the flowers do. Some species’ foliage starts to turn yellow and die off before the flowers are fully open. Plant the bulbs with other plants that will obscure the wilting foliage to help mask it. Alliums do well with hosta, astilbe, and perennial geranium.
When your alliums are blooming, you may anticipate seeing a lot of pollinators. Any type of habitat garden will benefit greatly from the inclusion of these bulbs.
Like their relatives in the vegetable garden, alliums hardly ever have insect or disease problems. Rarely do bothersome rats and deer show any interest.
Most alliums are perennial plants. They will typically bloom again if the species you are planting is winter hardy and the bulbs are suitable to the growing environment in your yard.
Caring for Alliums After They Flower
Allium wasted flower heads can be removed or left in situ once flowering is over. The seed heads are viewed as an intriguing decorative element by many gardeners. Depending on your environment, they may persist far into the beginning of the fall.
Large-headed alliums like Schubertii and Globemaster hardly ever produce viable seeds. Purple Sensation and drumstick alliums will reseed if the conditions are favorable. Simply remove the seed heads after the flowers have faded and before the seeds develop to prevent a carpet of tiny volunteers.
There are herbaceous alliums as well as alliums that grow from bulbs, including varieties like Millennium and Summer Beauty. These plants have a big root system and come back every year to blossom.
Alliums that emerge from bulbs require their foliage in order to generate energy for the blossoms of the next year. Therefore, it’s crucial to let these plants die back organically. The leaves may typically be removed with a simple tug once it has turned yellow and dried. Trim off the wasted blooms from herbaceous alliums with hedge shears or scissors once they have stopped blooming. This will maintain the plants’ clean appearance and might promote a second flush of blossoms.
Alliums can be moved in the spring.
When the foliage has sufficiently faded down, in the summer or fall is the ideal time to transplant spring bulbs. Flowering spring bulbs use their foliage to store energy for the blooms of the following year. Therefore, before attempting to relocate the bulbs, the plants must be allowed to organically die back to the ground.
Wait until the end of the fall, again until the leaf has died back, if you need to move summer flowering plants like canna or dahlia. These can be moved to a new position in warmer climates, but in cooler areas, now is the time to dig them up and store them for the upcoming planting season.
how do you dry alliums?
Pick off seedheads that are starting to fade and store them for a few months in a cold, dry place, such a shed or cellar. To use as Christmas decorations, I like to dry my seedheads and then spray-paint them silver.
are alliums edible?
Since they are all members of the allium family, onions, leeks, and garlic are often consumed foods. Alliums are theoretically edible, but beware eating any that are designed to be aesthetic garden plants because they may have been chemically treated.
are alliums good for bees?
In the spring, bees and other pollinators are all over our alliums. Our neighborhood beekeeper also claims that the honey doesn’t taste oniony.
do alliums need staking?
Even the tallest alliums won’t need staking since their sturdy stems can hold them if they are planted deeply enough in full sun (so they don’t extend toward the light) and in a sheltered location (so they don’t blow over in the wind).
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.
Are alliums self-propagating?
Spread alliums? Yes, the plant’s bulbs and seeds will grow and spread without much help from you. Typically, they will disperse at their own rate and stay put until they are moved or split.
Can allium bulbs be planted too deeply?
To guarantee that you get to enjoy the blossoms, it’s critical to plant bulbs at the proper depth. If bulbs are buried too deeply, they may not emerge at all or produce only foliage instead of blooms. Although digging the bulbs too deeply is preferable to digging them too shallowly, the bulbs are more likely to be accidently dug up or to be eaten by squirrels if they are.
There are certain exceptions to the general rule of planting bulbs at a depth that is three times their size.
Spring-flowering bulbs
10 cm, or three times their depth, in snowdrops 10-15 cm Iris reticulata 10 cm, or three times their depth, for crocuses 15 cm, or three twice their depth, for daffodils 10 cm, or twice their depth, for hyacinths 20 cm, or three times their depth, for tulips Crown imperials and Fritillaria imperialis: 30 cm, or three times their depth Snake’s head fritillary, Fritillaria meleagris: 10 cm, or five times their depth 30 cm, or three times their depth, for globe alliums Three times their depth, or 15 cm, for Allium sphaerocephalon Camassia: 10 to 15 cm deep, or roughly twice the bulb’s height
Summer-flowering bulbs
15 cm Eucomis 15 cm, or three twice their depth, for lilies 15 cm deep gladioli 10 cm, or three times their depth, is the crocosmia. Dahlias: slightly below the surface of the soil (start them off in a pot under cover) Cannas: make sure the top of the corm is barely visible? Nerines: at the surface of the earth
Can I move bulbs throughout the summer?
Best Time to Transplant: Long before or after flowering, when the plant is dormant. When you have time is perhaps the second-best time.
Moving bulbs is best done when they are dormant, either before or after flowering. The logic for this scheduling is straightforward: if the plant is not in bloom, you cannot interfere with blossoming.
However, you can also move them as they are leafing, budding, or flowering. The secret is to replant the bulb at the proper level and to disrupt the roots as little as possible. Every species has a different ideal depth. Verify the instructions on the tag if the bulb is new. If it was a garden transplant, replant it at the same depth where it was growing.
Moving bulbs is only to be avoided immediately after blossoming. At this time, the flowers have finished blooming and the leaves are storing energy for the upcoming blossoming season in the bulb. This procedure can take many weeks for certain blossoming bulbs. When the leaves turn brown, dry, wither, and die off, you know it’s finished.
How can plants be moved without getting hurt?
It’s true that you don’t have to leave your garden behind just because you’re moving.
There are a lot of reasons why you might desire to relocate your garden. You might wish to move your tomatoes and other veggies inside your new greenhouse before October arrives if you recently bought one. Maybe you recently purchased a new house and want to move your beloved perennials to the new landscaping. You can also just wish to plant potted plants in the ground.
Whatever the cause, you feel the need to relocate your garden from its current site. You shouldn’t do this without first doing some research. Get your hoes, wheel barrels, and expanding hoses ready, people; moving a garden successfully involves many steps. Now let’s go!
If you are able, choose the season you move
Never expose the roots to wind, heat, or sunlight. The roots of plants can quickly dry out if you take them out of their pots and set them where you want them in the garden. Just before planting, remove each plant.
Any other time is preferable, provided you aren’t relocating into a snow paradise. Of course, there are advice we’ll provide along the way to safeguard your garden’s safety if you’re forced to move it in the middle of the summer.
Mark where everything is going to go first
Whatever the new location of your garden, make sure the planting areas are prepared before you start digging and moving things around. In other words, make it clear visually what is going into them to prevent confusion. Make sure the dirt is prepared at the bottom of larger pots if you wish to plant them there so that the transfer will happen smoothly. On the other hand, if you are planting straight into the ground, ensure sure your planting areas are already dug out and sufficiently large before anything is removed.
We advise soaking these areas in water before relocating the plants if you are doing it during the summer heat. After the shock of being uprooted, the roots will want hydration.
Create a temporary nursery for your plants by digging trenches if you are unsure of where you want to plant.
Pot, bucket or burlap: get the transportation ready
Skip this step if you are transferring your garden from one pot to another or if you are putting your potted plants in the ground. However, you will need mobile containers if you plan to relocate your garden from one house to another. Burlap should be used to transport the root ball if simple buckets or pots are unavailable. Making ensuring the shipment goes as smoothly as possible is vital because the shock of moving is enough to damage a lot of plants.
Use a special watering schedule for soon-to-be in-transit plants
It’s critical to correctly hydrate your plants while they’re being transported. Not to mention that irrigated plants can be pulled out with their roots intact more easily.
The night before you intend to transfer your garden, you should water it so that the plants will be properly hydrated. This enables them to maintain what is known as “the shock of travel.
Second, give the roots plenty of water; soak them well! In the unlikely event that you have plants with bare roots (or “Before being replanted, the bottoms of these plants must be immersed in water for two to three hours (naked roots). Just a few typical bare-root plants to watch out for are listed below:
- Shrubs
- Hosta
- Daylilies
- Roses
- tree fruit
- Wild Onion
Trim excess stems
It is advised that you remove any stems or foliage that is dead or has too much. This will lessen any stress that your plant may feel. However, not all plants really require this, so use your best judgment!
Dig up using the drip line
It’s time to remove those plants now. But you shouldn’t dig around the plant’s roots. A healthy root could be chopped up if you do that! Instead, use a hand shovel and carefully dig a ring around the plant’s main stem, taking note of the location of the roots. The drip line, often known as the spot where your plant drops water onto the ground, is a fantastic place to dig up plants.
The ring you dig around larger plants needs to be at least 6 inches deep. Any size plant will likely have some of its roots clipped when you begin digging around it. This is acceptable, but make sure the incisions are precise and not torn.
Use a bigger shovel (or several, for larger plants) to push them out of the way once the ring has been dug. The soil around the root ball will act as protection, so don’t shake it or take any of it out. Prepare your plants for their final destinations by placing them on their delivery vehicles!
