How to Plant Potted Tulips In the Ground: 11 Tips for Success

Tulips are flowering perennials that are easy to grow and maintain. Many varieties produce a stunning array of colors, from gorgeous reds and yellows to deep purples and whites. If you’ve never grown them outdoors, they’ll quickly become some of your favorite flowers. 

Although they’re from Asia, they became a symbol of luxury in the Netherlands and quickly became the country’s symbolic flower. Because of this, Dutch botanists bred them to create around 100 species and 3,000 varieties! 

Besides being colorful, they’re easy to grow both indoors in containers and outside in your garden. They need very little care and maintenance once they’re maturing in the ground. Although they’re easy to maintain, they can be slightly tricky to propagate and transplant. 

If you want to plant potted tulips in the ground, there are a few tips to consider. It may be tricky, but with a little patience and care, you can do it successfully.

Step 1: Make Sure You Have the Right Variety

Most potted tulips are selectively bred for their traits. Perennial tulips need an extended period of cold weather to bloom. This encourages the bulbs to create a sturdy root system in the ground before spring. 

Unfortunately, the majority of the colorful varieties you find in nurseries today are hybrids. Besides their traits, most were selectively bred to create bountiful flowers and die off in the same year. If your potted tulip is one of the hybrid annuals, you probably won’t be able to transplant it in the ground. 

However, if you’re growing a perennial variety in a container, you have a shot at transplanting your bulbs outdoors. Although you may not be successful, it can be a fun experiment. 

Step 2: Transplant During the Spring

While the ideal time to plant tulips is in the fall, you can plant them in spring. Ensure you’ve chilled the bulbs for 12 to 16 weeks first. Decide if your tulip is a perennial and not an annual. Then it’s time to prepare it for the outdoors. Before you do that, make sure it’s already bloomed. This usually happens in early to mid-spring. 

Time your transplanting shortly after the flowers are done blooming. Too early and your plant will send too much energy into developing flowers and not roots and new growth. Too late and the energy will go into developing seeds.

Step 3: Deadhead the Flowers

After your flowers bloom, it’s important to get your potted tulips in the ground quickly. The first step is to clip off the spent flowers, a process known as deadheading. If you’re planting a perennial tulip, deadheading is important to prevent them from sending energy into developing seeds. The plant will divert its energy to growing roots and new foliage. 

To deadhead your tulip, start with sterilized pruners or sheers. Just above the first set of leaves, snip the flower stem. Make sure the cut is clean. 

If you don’t deadhead your tulips before replanting, the plant will have less energy to send to the roots. It will be harder for the plant to acclimate to the new soil and put on healthy new growth. 

Step 4: Acclimate Your Indoor Plant

After deadheading, the next step is to get your plant acclimated to the outdoors if you’ve grown it indoors or in a greenhouse. This process is known as hardening off, and like seedlings, transplanted container plants need to go through this step. This is less important if you grow your tulips outdoors in containers. 

Indoor plants are used to steady temperatures, humidity, and light. Even things like wind can affect growth. To do this, start by placing your plant in a shady spot outdoors while it’s in its container. Do this for a few days to slowly expose it to the swings in temperature and humidity. 

Afterward, gradually move your potted tulip to a sunnier location. You want to slowly expose your flower to the sun because too much sunlight at once can harm the plant. Once your potted tulip can withstand direct sunlight, it should be ready for transplanting in the ground. 

Step 5: Don’t Disturb the Roots

Transplanting puts your plant under stress, causing it to lose its leaves, wilt, or show other signs of damage. This response is called transplant shock and can be harmful to your delicate indoor flowers. 

The first step in preventing transplant shock is to avoid disturbing the roots. First, check for signs your plant is root-bound or unhealthy. If the roots are growing out of the container’s drainage holes or out the top of the soil, carefully remove the root ball from the container. 

In some cases, you might have to cut the container to remove your tulip. You can do this with plastic containers, but at this point, it might be better to save your container and buy a new bulb. 

Step 6: Plant Your Tulip

Dig a hole a little deeper than the root ball and soil of your potted plant. Make sure the soil is well-drained and free from large roots. Add a little compost or balanced fertilizer in the bottom of the hole and mix it in with the soil. 

Place your tulip with its soil and rootball intact in the hole and be careful not to disrupt the roots. Add compost to the soil to boost the nutrients. Your flower will need extra energy to thrive in its new environment. 

After planting your potted tulip, add a little topsoil to the crown and cover any open spaces in the hole. Consider adding mulch to keep the moisture in and provide a healthy environment for beneficial critters such as earthworms. 

Step 7: Mark Your Planting

This step may seem silly but it’s easy to lose track of your plants outdoors. Leave a little marker near your transplants so they don’t get trampled or forgotten. 

I like to use small rocks to encircle my perennial flowers early in the season. However, stakes, flags, or any cloth marker will do. 

Consider planting your transplanted bulb near other perennial tulips. This will make it easier to keep track of and compare to other flowers in your garden. 

Step 8: Water Your Transplanted Tulip

After you successfully acclimate your plant to the outdoors and transplant it into the soil, give it a good watering. Keep the soil moist but not overly watered. Your plant will likely show signs of transplant shock so it’s important to keep up with your watering schedule. 

Once your tulip is thriving in the ground, maintain a consistent watering schedule through the growing season. Be careful not to overwater your plants. Tulips are susceptible to root rot. 

Step 9: Cut the Foliage Back in the Fall

If you successfully transplanted your tulip, it may be healthy enough to survive the winter. To encourage it to store enough energy to bloom the following spring, cut away its dead foliage in fall. 

Wait until it’s completely dead and cut it down to ground level. This encourages the bulb to enter dormancy. During winter, it will build up and store enough nutrients to supply new growth and blooms the following spring. 

Step 10: Give it a Little Compost

To help it along before the winter cold arrives, add nutrients to the soil. Add a small layer of compost above the soil. Compost adds a balanced amount of organic nutrients that will improve the soil. 

In the spring, the bulb will use the nutrients to encourage healthy new growth. If you use a fertilizer, use a balanced NPK ratio and follow the product’s directions. Avoid overfertilizing because it could shock the plant.

Step 11: Add a Layer of Mulch

Mulch is the final step to protecting your bulb over winter. This will insulate the bulb and keep the soil temperature regulated. It also helps keep moisture in the soil and protect your plant from predators. 

Keep the layer of mulch around 2 inches deep. Hardwood mulch works well for tulips because it encourages draining and keeps mildew away.
