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.
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
Will tulips grow through vegetation?
The most well-liked spring-flowering bulbs are the tulips. With more than 100 different tulip species and countless hybrid varieties, gardeners may have their landscapes bursting with color each spring. The ground can still be left naked once the tulips have faded, though. These voids can be filled in by ground cover, which also acts as a carpet for your tulips.
Avoid picking a ground cover that is exceptionally dense, thick, and woody (i.e., has woody stems like those seen on shrubs). It will prevent your tulips from growing up through it. Avoid junipers like “Wiltonii,” for instance, which are fantastic for controlling weeds but will also prevent the establishment of spring-blooming bulbs like tulips.

Choose sedums like “Angelina” and other low-growing ground coverings like “Creeping Jenny.” Thyme varieties are also great choices. Because these ground coverings don’t have heavy, woody stems, the tulips may climb up through them more easily.
Directly above the tulips, plant. You shouldn’t be concerned about putting ground cover right on top of your tulips. The tulips will rise to the surface eventually. Just create a 1-inch-deep trough where you want your ground cover, then fill it with the ground cover. Use earth to cover.

- Because these ground coverings don’t have heavy, woody stems, the tulips may climb up through them more easily.
Your ground cover should be placed 12 to 18 inches apart. If you are planting more than one pot of ground cover, you should spacing the plants at least this far apart because the majority of ground cover has a 12–18-inch spread. The gaps will be filled as they develop.
Additionally, you can surround your tulips with later-growing perennials. Your tulips’ unsightly dead stems will be covered by these perennials, such lilies and daisies.
Over time, any ground cover might become incredibly dense. Thin out the ground cover a bit to give the tulips a little more area to develop if you find that they are not growing as well.
What happens if tulips are mowed over?
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.
Can flowers be planted in grass?
If you find yourself feeling envious of your neighbors’ colorful lawns, it may be time to take steps to modify your own vegetation. You must first dig up all or part of the lawn and plant the seeds of flowering lawn weeds in order to convert pure grass lawns to wildflower lawns. After that, your work is finished.
Experts advise planting the wildflower seed on top of your current grass if you want to plant wildflowers on your lawn. Choose a location with soil that is reasonably fertile, great sward structure, and very few perennial weeds or aggressive grasses.
In the late summer, the lawn was mowed very short, leaving up to 50% of it naked by raking. In the fall, scatter by hand the bare areas with a mixture of wildflower seed and sand.
