Bulb naturalization is a great method to add brightness to lawns. Snowdrops (Galanthus), crocuses (Crocus), squills (Scilla), checkered lilies (Fritillaria meleagris), and numerous other attractive perennial bulbs grow nicely in grass. As long as they receive the right lighting and are planted in soil with the right drainage, they will gradually multiply if left unattended in the ground and will reappear every spring.
- Make natural-looking plantings and avoid evenly spacing your bulbs for the most impact. To achieve a natural effect, gently toss them on the lawn and plant them wherever they land. The majority of bulbs look their best when grown in unstructured drifts and swathes. Don’t forget to allow for natural growth.
- Pick a small number of colors, then try to mass them. Avoid mixing too many colors together to avoid having an artificial and perplexing planting.
Lawns that have been planted with perennial bulbs need to have their mowing schedule changed.
- The selection is primarily limited to spring or fall-blooming bulbs since lawns require mowing. When the bulbs have done flowering, resist the desire to make the initial cut. The bulb will be deprived of vital nutrition if the foliage is removed before it has fully ripened, which will result in a subpar second-year show. The grass shouldn’t be cut until six weeks after flowering is over in order to ensure a prolific flowering the next year. The more time you need to wait, the later the bulbs blossom.
- You must cease mowing your lawn in late summer if you grow colchicums and fall crocuses there.
- Late fall lawn mowing should be done to allow your spring bulbs to neatly poke their heads above the ground.
Can daffodils grow through vegetation?
A: I read your recent post about reducing the need for mulching by utilizing more groundcover plants. It makes sense to choose liriope. But when other plants like tulips and daffodils try to emerge, will it choke them out? Or will they get along?
A: Spring bulbs can be interplanted with many of the shorter and “looser” groundcovers. For instance, the bulbs of tulip and daffodil plants can push through pachysandra, vinca, sweet woodruff, leadwort, hardy ginger, and even ivy.
A groundcover of pachysandra that I interplanted with golden daffodils around 15 years ago is one of my favorite spring beds in my backyard. The bulbs are still growing and their clusters have even gotten bigger.
On the other hand, liriope plants have extensive root systems that gradually expand until they form a touching mass. When that occurs, it becomes almost impenetrable. That’s fantastic for controlling weeds but not so beneficial for the long-term health of the bulbs.
In the beginning, you could interplant bulbs between the liriope plants, but eventually the liriope would close the entryway.

Is it okay to mow over daffodils?
Before mowing bulbs on the lawn, you must wait until the foliage naturally dies back. The bulb can then reabsorb the nutrients from the foliage and utilise the energy for the flowers that will bloom the following year. Without these vitamins and minerals, bulbs perform poorly the following year and eventually perish.
Early spring blooming little bulbs may wither away before the first mowing. These include crocuses, squill, and snowdrops. It can take a few weeks for tulips and daffodils to wither away. When the leaves turn yellow or brown and lie limp on the ground, it is okay to mow. The leaves typically rise off the ground without any effort.
How can you make daffodils grow naturally in grass?
Nothing is more beautiful than a lawn covered in dancing daffodils, drifts of snowdrops, sparkling pools of yellow crocus, or a carpet of golden aconites. It’s simple to naturalize bulbs to produce displays like these if you plant the bulbs now, in the fall. Select bulbs that self-seed to boost the impact year after year. Many of them will flourish in challenging garden locations.
The best results are obtained by “naturalizing” bulbs that are best suited to the circumstances of your garden and mimic nature. Compared to most cultivars, species bulbs appear more natural, establish faster, and spread more effectively.
Which are the best bulbs for naturalising?
Try snowdrops near deciduous trees, at the bottom of hedges, and on grassy banks that are shaded. They prefer dappled shade with moist but well-drained soil since their roots will stay cool during the heat. The ideal species to use are the undemanding and dependable Galanthus nivalis and the double-flowered G. nivalis ‘Flore Pleno,’ which should be planted in March rather than as dormant bulbs in the fall. To expand the number of people, lift and split every two to three years.
Winter aconites (Eranthis hyemalis), which bloom in January and February, can be slow to get going, but as long as they have deciduous shade, where it can stay cold and dry in summer, they can quickly pile up to form a carpet of gold. Plant this bulb’s corms in the fall, among the green plants in the spring, or you may try sprinkling the seed in the fall. Put them under shrubs and deciduous trees.
Both the spring-flowering Cyclamen coum and the autumn-flowering Cyclamen hederifolium are hardy cyclamen that appreciate the same wooded settings. Both species’ corms should be planted in the fall, but keep in mind that C. hederifolium grows more quickly and has the potential to overtake C. coum.
Crocuses can be grown in shorter grassy areas that receive full or partial sun. Lilac Crocus tommasinianus and its variants begin to bloom in January and spread quickly. You can also try Dutch crocuses (Crocus vernus), which cluster up quickly, and Crocus chrysanthus, which blooms in February. The purple “Vanguard,” the white “Jeanne d’Arc,” the striped “Pickwick,” and the golden “Yellow Mammoth” are all excellent hybrids. Plant a lot of bulbs beneath turf in drifts that you can cut under and peel out after the bulbs are in before refilling.
Tulips from delicate species are suitable for naturalizing. Between March and June, the tulip species Tulipa humilis, T. clusiana, T. tarda, and red T. sprengeri bloom. Plant them where they land after sprinkling them on the grass’s surface. They require sun and freely draining soil. Plant them at least 15 cm deep, and they will return each year.
By self-seeding, the little blue scillas and chionodoxas easily naturalized. A March staple is Scilla bifolia and S. bithynica. The majority of chionodoxa species are effective naturalizers, bringing a sea of blue flowers to the C. forbesii and C. luciliae light shadetry.
Species daffodils have the most authentic appearance. March to April is when the wild daffodils like Narcissus lobularis, N. pallidiflorus, and N. obvallaris bloom. With scented Narcissus poeticus var. recurvus, follow them in May. Try N. cyclamineus in soil that is acidic and wet.
The hardier cultivars “Jack Snipe,” “February Gold,” “Thalia,” and “Trena,” the soft-hued “W.P. Milner,” and the multiple-headed “Hawera” all resemble species daffodils. Daffodil single bulbs should be planted in the fall.
Plant the bulbs of snake’s head fritillaries (Fritillaria meleagris) in autumn for flowering in April and May if the grassy area is moist in the summer. Or select the Camassia quamash with blue flowers.
How do I naturalise bulbs?
- For a natural effect, disperse bulbs at random and plant where they land. Just before planting, mow the lawn to make it easier to view the seeds and plant them.
- With a bulb planter, one can grow larger bulbs like tulips and daffodils. These take out a core of soil to make room for the bulb, then crumble the soil plug back over the bulb and restore the turf, firming it to the same level as the grass around it.
- Smaller bulbs, including crocus, scilla, and chionodoxa, can be scattered randomly or planted in groups in larger holes, several fork holes, or under turf rugs that have been cut with a spade or turf iron and peeled back.
- There is no need to fertilize because the grass will profit rather than the bulbs from doing so.
- To give bulbs time to regenerate, mow after the foliage has faded down, usually six weeks after flowering. Wait to mow the bulbs until after the blossoms have released their seed if you want the bulbs to self-seed.
- Every two or three years, mature clumps can be plucked, separated, and the individual bulbs replanted. Congested clusters should be left alone to grow.
- If weeds do appear, remove them by hand or use a specific weed killer to prevent them from growing and outcompeting the bulbs.
How can you make daffodils grow more?
Unsurprisingly, improving either mode of reproduction is the best approach to promote the spread of daffodils. For instance, you should be prepared to take cuttings as the bulbs begin to divide and plant them as necessary if you wish to increase the rate at which they reproduce through asexual reproduction.
Naturally, this takes a lot of time, so you’re probably more interested in letting your daffodils expand on their own.
This entails doing all in your power to increase the likelihood that your daffodils’ seeds and pollen will blow, settle in fertile soil, and then produce new flower buds.
However, daffodils are constrained in ways that other flowers are not. For instance, the pollen of flowers that use this as their primary means of dispersal and reproduction, such as daffodils, is substantially heavier.
As a result, you cannot rely on the pollen to travel far. As a result, if you anticipate that a simple wind gust in the spring would spread the pollen from your daffodils across your yard to fertile land, you should reconsider.
Perhaps you believe that the buzzing of bees in your backyard will be beneficial, as they are with other flowers. Daffodils do not have nectar to draw them, so that is out of the question (or luckily, if you want to control the spread).
Additionally, it may take daffodils months or even years from the time they are planted until they reach their full potential.
Since most of us aren’t prepared to wait that long to spread daffodils over our yards, this approach is definitely not the one you want to use first if you want them to spread quickly.
As previously said, you must instead assist the bulbs by doing a little bulb division yourself. We’ve already talked about how this works, but you can speed things up.
Dig a hole, put the bulbs there, and wait for them to grow once you have divided the bulbs or allowed this process to occur naturally.
You’ll want to make sure that they are large enough to accept them, so dig them at least two to three times larger than the size of the bulb itself, just like you did with the holes for your initial daffodils.
Once you’ve completed that, the daffodil bulb can be planted into the hole. When you begin to fill it back in, make sure the bulb itself stays below the soil line.
Do bulbs pierce sod to grow?
I used to lustfully go through my dad’s bulb catalogs when I was a kid. They were jam-packed with beautiful color photographs and succinct but powerful descriptions (some of which, by the way, had been “enhanced to make the plants even more appealing, but I didn’t know that yet). These pamphlets claimed that all of the bulbs were simple to grow and that the outcomes were guaranteed. As a novice gardener, I was already drooling at the prospect of giving them a try, which I eventually did, a couple at a time. I used to save my pocket money to purchase bulbs (in the fall) and seeds while my buddies bought candies and comic books (in the spring).
A little piece on how to naturalize spring bulbs in the lawn could be found in one of my dad’s catalogs. Naturalization is the process of permanently establishing a plant in a manner that appears natural. As a result, the lawn would bloom into an alpine meadow when the snow melted. A mountain meadow? What an intriguing concept! So, pushing my finances to the limit, I bought 10 woodland crocus (Crocus tommasinianus) bulbs (corms) specifically to plant in the family lawn because the text claimed that it was the greatest crocus for naturalizing.
According to the literature, it was necessary to plant the bulbs unevenly, in the most natural way possible, rather than in a circle or square, which would look quite artificial. In order to achieve this, it was advised toss the bulbs into the air and plant them where they landed, which is what I did.
Disaster! Two of my priceless bulbs were lost on the grass (easy to do when the grass is tall, as crocus bulbs are very small). I can still feel my anger! (They actually made a comeback in the spring, blooming on the ground’s surface without even being planted!)
Even as a 10-year-old, I was able to recognize that throwing bulbs into the air is not a rational way to accomplish this. If you had a lot of bulbs to naturalize, just think of all the individual holes you would need to dig. Too much labor must be done!
Despite that initial mistake, my strategy to naturalize crocuses finally had great success. There were an increasing number of them each year. There are now thousands—possibly tens of thousands—after 55 years! They virtually blanket the yard of the family home where my brother still resides for a fleeting but vibrant burst of color.
The Easy Way of Naturalizing Bulbs in a Lawn
Ignore launching light bulbs into the air! or digging distinct holes and planting each one. This is the correct way to put bulbs in a lawn.
Instead of drilling individual holes for each bulb, take a shovel and remove a section of sod on three sides. Then, instead of removing the sod, slide the shovel under it and fold it back. You will then have a hole in which to plant numerous tiny bulbs. Don’t stress about planting bulbs precisely; because of their contractile roots, bulbs will actually plant themselves deeper if they feel the need to.
Just disperse them erratically for a “natural effect. I just drop the bulbs into the hole and jiggle them about a little with the shovel’s tip. Even if a bulb is planted upside down, it will still bloom beautifully and eventually correct itself, so I don’t even bother placing them right side up. I just leave them where they fall. In order to extend the blooming season, you can combine many bulbs with varied blossoming times in the same planting hole.
Just replace the sod in its original location, step on it to compact it, and then thoroughly water it. The bulbs will sprout through the sod as if it weren’t there the next spring. (A sprouting bulb’s sharp tip is made to punch through roots and other obstructions.)
It’s interesting to note that this planting method even keeps squirrels away from crocus bulbs because it takes too much work to dig through thick sod to find the bulbs. They prefer to take them out of your garden beds’ recently disturbed dirt. They primarily favor crocus corms and tulip bulbs, which are rarely naturalized on lawns. (The only crocus they refuse to consume is the forest variety, C. tommasianius.) Squirrels don’t care about the other little bulbs, such as squills, snowdrops, winter aconites, etc.
Don’t fill the planting hole with bone meal! This does draw squirrels and motivates them to dig for the bulbs more diligently.
Be aware that in well-drained soil, tiny bulbs naturalize the best. Some plants, crocuses in particular, can struggle to grow well on lawns that are planted in dense clay soil that is perpetually moist.
Care of Naturalized Bulbs
In actuality, no attention is necessary. The idea behind the phrase “naturalize” is to simply leave the bulb to take care of itself after planting. Plant them and leave them to complete their natural cycle without your intervention. They return every spring since they are accustomed to doing so, flower, put out leaves, and then vanish as soon as the grass turns green. And the majority of spring bulbs that are good candidates for naturalizing will grow in the grass over time, some creating large clusters and others spreading more thinly.
What about mowing, though? Just cut the grass when it’s time to mow! Don’t think about the bulbs. By then, the majority of bulbs will already be dormant, and their leaves will be gone or fading quickly. When it comes time to mow the lawn for the first time with the newest bloomers, the leaves might not be completely gone, but don’t worry about it. Although cutting off the tip of their leaves may cause a small amount of damage, the leaves were already on the edge of dying.
But Doesn’t Naturalizing Harm the Lawn?
Not at all, no. There are some lawns that are overflowing with bulbs in the spring but are as lush and green in the summer as nearby lawns that never get a blossom. The growth cycles of the two different plant types (bulbs and grasses) are diametrically opposed. Late in the fall, bulbs begin to grow underground. They continue through the winter, produce flowers and leaves very early in the spring, and then go into hibernation just as the grasses on the lawn start to grow. The lawn grows until the fall, at which point it enters a dormant state just as the bulbs begin to sprout new roots. The two get along great.
Although no one is sure why, it’s fascinating to notice that lawns with naturalized bulbs nearly never experience issues with lawn insects (grubs, chinch bugs, sod webworms, etc.). Perhaps the LEDs serve as a deterrent?
Mow, fertilize, dethatch, and even use lawn herbicides (so long as you don’t apply them when the bulbs are in leaf) are all acceptable lawn maintenance practices. All of the aforementioned won’t hurt the bulbs. Aerating the lawn is the only thing that will cause some slight damage to the bulbs. When damaged, bulbs have the capacity to create replacement bulbs and recover rather fast. The advantages of grass aeration, however, are few. For instance, my lawn thrives even though I never aerate it.
Which Bulbs Shouldn’t You Naturalize in a Lawn?
Any hardy spring or fall flowering bulb might potentially be naturalized in a lawn, but dealing with bulbs that obstruct mowing is a hassle. That includes late-blooming bulbs like grape hyacinths (Muscari spp.) and the majority of daffodils (Narcissus spp.), which will be fully bloomed by the time the grass requires its first mowing. (It’s true that daffodils and grape hyacinths look lovely in a lawn; you could just mow around them, but it requires more work.) On the other hand, the earliest and tiniest daffodils, like “February Gold,” can naturalize in a lawn extremely successfully.
Moreover, the “Any bulb that grows tall plants, such as the majority of alliums and fritillarias, is not a good choice. Once more, mowing will be a challenge.
Tulips check a lot of boxes, but I don’t think they initially look good in a lawn. However, their biggest drawback is that they have a tendency to be transient, and you want native bulbs to be genuinely, solidly perpetual.
Regarding fall-flowering bulbs, such as cochicums (Colchicum spp.), while they can generate enormous leaves in the late spring that must be mowed around, they do give an excellent effect in a fall lawn. In the fall, you would also need to mow around the blooms. Large estates do have them naturalized in their lawns, but estates also have “people to complete the task. For the typical home gardener, I believe the added work is a bit excessive, but you decide.
On your property, you can still naturalize larger or later-blooming bulbs, just not in a grass that gets mowed frequently. For instance, in a meadow or in a wooded region where the mower never travels, you can let them grow naturally. In this manner, there is no need to mow around them with the mower, allowing their foliage to develop unhindered.
Which Bulbs Can You Naturalize in a Lawn?
The best bulbs for lawns, according to the typical home gardener, are those that bloom early in the spring and have gone into dormancy by the time the lawn has to be mowed. Just keep an eye out for bulbs with small leaves (which rules out netted irises [Iris reticulata], by the way).
Some of the best are as follows:
- Hardiness zones for crocuses (Crocus spp.) 38
- Hardiness zone 38 for extremely early forms of daffodils (Narcissus spp.
- radiance of the snow (Chionodoxa spp., now Scilla spp.) Zones of hardiness 39
