Tulips: Everything You Need To Know Before Planting

Tulips (scientific name: Tulipa) are sun-loving flowers that are easy to grow in the garden in both beds and containers. They thrive in climates that include cold winters and hot summers and bloom perennially in the spring, as per American Meadows. Tulips come in a wide variety of colors, including yellow, orange, pink, and purple. Most blooms are characterized by an elongated cup shape with petals growing upwards and enclosing around the middle. Due to the many tulip types, you'll find that their size differs depending on the type you plant. However, the majority range between 10 and 18 inches, according to Gardenia. This plant is also marked by bright-green foliage that both precedes the emergence of the flower and continues after the last bloom has died off.

Many people hold the misconception that tulips come from Holland, the country known around the world for producing enormous fields of colorful blooms. However, they are native to Central Asia in the region around the Tien Shan mountains, as per Dutch Review. It wasn't until sometime in the 16th century that tulips made their way into the outdoor tapestry of western countries, starting in Holland. Nowadays, each color of the tulip bloom has a unique meaning, according to FTD by Design. If you'd like to symbolize happiness, you can grow a pink variety, while yellow blooms are typically associated with uplifting thoughts.

How to use tulips in the garden

There are endless options for planting tulips in your garden to take advantage of their wide range of colors, heights, and bloom appearance. Many people choose to plant tulips by the hundreds as each bulb typically produces just one bloom. When it comes to deciding how you want to design your garden with the addition of tulips, you must first think about whether you want to plant your tulips in beds or in containers. The advantage of planting in containers is that you can place your tulips in locations that aren't conducive to planting in the ground, such as on patios, decks, and balconies.

When you plant tulips directly in the soil of your garden, you can create elaborate tapestries of color that will brighten your outdoor space. Better Home & Gardens recommends planting tulips along fences or rock walls in your garden to create colorful boundaries. You can also get creative by mixing different colors in the same bed or general space. Another popular idea is to plant tulips with other perennial flowers for a variety of texture in the same space. You'll also want to pay attention to the size of the plant once it blooms. Taller varieties should be placed in the back of the bed so as not to obstruct the other varieties or flowers in that area. If you have a stone pathway through your garden, try planting tulips in a row along the edge of the path.

How to grow tulips

Tulips grow from bulbs that are planted in the ground in the fall before the first frost hardens the soil. This plant must pass through winters with soil temperatures below 55 degrees Fahrenheit in order to create the optimal conditions for survival once the blooming period arrives in the spring, as per the Amsterdam Tulip Museum. If your climate doesn't experience cold enough winters, you can also refrigerate the bulbs for two and a half months before planting them in the ground in the early spring, according to American Meadows.

Once you've purchased your tulip bulbs and defined a space in your garden to plant them, you'll need a shovel or small trowel to dig into the soil. If you'll be planting mass beds of tulips, a large shovel will allow you to dig trenches deep and wide enough to accommodate the number of bulbs. The depth you'll aim for should be around 6 to 8 inches. When placing the bulbs in the soil, make sure the pointy end is facing upward and that each one sits around 4 to 6 inches away from its immediate neighbors. After situating your bulbs at the base of each hole or trench, cover them with soil, making sure to pack it securely over the top to prevent air from surrounding each bulb instead of soil. You can water the bulbs immediately after planting but won't need to provide any additional care until they bloom.

How to care for tulips

Part of properly caring for tulips means providing them with the adequate growing conditions before planting them in the ground in the fall. You'll want to make sure the area you choose receives full sunlight during the bloom period, as noted by The Spruce. Keep in mind that your garden may receive different amounts of sunlight depending on the time of year; an area that is only partially sunny in the fall may be in full sunlight come spring. As for soil conditions, you'll want to make sure your tulips are placed in a well-draining area of your garden as they loathe overly wet conditions and will likely rot and die if they sit for too long in wet soil. You also can add a bit of mulch or fertilizer when planting the bulbs to provide an extra kick of nutrients through the winter.

Tulips often need less water than most people think, especially in regions where rainfall is plentiful in the spring. As a general rule, tulips will need water every couple of weeks, either from rain or from your garden hose — just be careful not to overwater. Another important part of caring for your tulips is cutting back the green foliage of the plant once the blooming season has ended. You'll want to wait until the foliage starts turning yellow or brown to avoid removing an important source of nutrients for the bulb that will help sustain it through the dormancy period.

Varieties of tulips

Finding the right tulip for your outdoor space is easy considering that there are more than 3,000 varieties of the plant available for purchase, as per Home Stratosphere. Tulips come in a wide variety of colors, sizes, and bloom shapes, and all originate from a very specific mountain range in Central Asia. Over the centuries, they have been manipulated by scientists to expand the number of varieties. Some hybrid varieties take things a step farther and even feature multi-colored blooms. No matter which variety (or multiple varieties!) you choose for your garden, rest assured that you will be rewarded with gorgeous blooms that will kick-start your spring in the most colorful way possible.

Among the many varieties of tulips is the stunning Queen of Night, which features dark-maroon blooms that appear almost black in color and create a powerful contrast to other lighter varieties. If dark isn't your thing, try the Apricot Beauty with its orange-pink petals that are streaked with a hot-pink accent. This variety also lets off a particularly fragrant scent that you will enjoy every time you step into your garden. The Double Sugar variety offers a twist on the traditional cupped bloom shape with its open pink and white petals that are often compared to roses. And Giuseppe Verdi is a sight to behold with its bright yellow blooms decorated with red stripes; this variety pairs nicely with the single-colored, bright-red Ad Rem variety.

Are tulips toxic?

The bottom line is that tulips are toxic to both humans and animals, explains the National Capital Poison Center. While humans have been known to consume tulip bulbs accidentally due to their uncanny appearance to onions, eating too much of this plant can cause gastrointestinal issues, including stomachache, vomiting, and diarrhea. It is also known to induce shortness of breath and a general feeling of weakness in the body. This unpleasant effect is not known to be fatal but may be more pronounced in children and animals. In the case of accidental ingestion, you'll want to contact a poison control helpline or your nearest emergency hospital for assistance.

Another common issue associated with tulips is a condition known as "tulip fingers," which is essentially a skin rash provoked by the chemical tuliposide. If you experience this rash, wash the affected area with water and soap. However, if the rash worsens or doesn't clear up, seek medical assistance. You can avoid skin irritations by using gardening gloves when handling tulip bulbs.

If you have young children and/or pets and are worried about accidental poisoning, there are a few precautionary steps you can take. You can consider installing a barrier around your tulip beds to prevent children and pets from getting close. Additionally, pets can be trained with positive reinforcement techniques to avoid approaching your tulips. You'll also want to make sure to store bulbs out of reach as this part of the plant is the most dangerous.

How to repot tulips

While typically planted in garden beds and meadows, tulips also grow nicely in pots and containers. This option is a great alternative for anyone who doesn't have a garden yet still wants to brighten up a balcony or deck with this colorful bloom. Tulips will eventually reach a point where they outgrow the confined space of a container or pot and need to be re-potted. The larger the container, the better when it comes to tulips. Extra space will provide the bulbs with the adequate amount of soil necessary to maintain nourishment through the dormant periods of the year. The container or pot should also have plenty of drainage holes to avoid bulb rot. 

The best time of the year to re-pot tulips is in the fall to correspond with the normal bulb-planting season. If you haven't already cut off old growth, you'll want to do this first before digging the bulbs out of their too-small container, suggests SF Gate. The next step is to fill the new container with potting soil, leaving 6 to 8 inches of depth before placing the bulbs on top. Potted bulbs can be placed closer together than they would be in the ground, at about 1/2 an inch apart from one another. Keep in mind that the pointy end should always face upward as this is where the bloom and foliage will sprout from. Cover the top of the bulbs with soil and water occasionally during the winter.

Tulip pests and diseases

Tulips are susceptible to several pests and diseases that can threaten their chances for survival or kill them altogether. Fungal diseases are especially detrimental to tulips and are often caused by overwatering and a lack of air flow. One such disease is known as Botrytis blight, which weakens and destroys the entire tulip plant, as per Gardening Know How. Pythium root rot is another fungal disease that weakens the bulb itself and prevents the plant from growing. One more fungal disease, basal rot, is marked by the patches of mold that grow on the bulb and disfigured blooms. Treating fungal diseases requires that you spray the infected soil with fungicide to kill off the spores. Infected plants should be disposed of. The best way to avoid rot is to take care with watering; a good rule of thumb is to err on the dry side when it comes to determining the water needs of your tulips.

In addition to fungal diseases, you'll want to keep an eye out for common tulips pests, which include aphids, slugs, caterpillars, and rodents, according to SF Gate. The latter like to dig up the bulb, preventing the plant from ever growing in the spring. Insect pests feed on the various parts of the plant and can often destroy it entirely when left unchecked. Insecticides are your best bet when it comes to getting rid of an infestation. As with fungal diseases, make sure to dispose of any infected plants.
