Tulips are colorful flowers with upright stems, typically blooming from early spring to early summer. Native to the foothills of the Himalayas and Eastern Turkey, tulips flourish in cool and dry conditions. This flower is relatively easy to grow in gardens or as a bush. Start with Step 1 below to get detailed instructions on how to grow tulips.
Steps
Plan and Prepare
Purchase tulip bulbs. You can find them at nurseries, garden centers, or reliable online stores.
- When selecting bulbs, choose firm ones without mold, bruises, or cuts. They should be a light brown color and wrapped in a thin, onion-like skin.
- Regarding quantity, each bulb will produce one to four stems and flowers, so plan accordingly.
- Choose bulbs by their name for consistency in appearance and growth. Bulbs are often grouped by color – for example, ‘yellow tulip’ – which refers to tulips of that color variety.
- Plant the bulbs within a week of purchase, as they do not stay viable on the ground for long.
Decide the best time to plant your flowers. Tulip bulbs should be planted in late fall, before winter arrives. The bulbs will go dormant for a few months before sprouting and blooming in spring. The exact planting time depends on your local climate.
- Pre-chill the bulbs if your area doesn’t typically experience freezing winter temperatures. Place the bulbs in a sealed paper bag and refrigerate them for 6 to 8 weeks. You can also buy pre-chilled bulbs from trusted suppliers.
- If you live in a region where winter temperatures regularly drop below freezing, you can plant the bulbs without chilling. Only plant when the soil temperature at a depth of 15 cm is below 12°C.
Choose the right location for planting. Select a spot that receives adequate sunlight for the specific type of tulip you’re planting. Space the bulbs about 10 to 15 cm apart, so choose an area with the right size.
- Most tulips grow best in full sun, which means at least 6 hours of sunlight per day. Some varieties can tolerate partial or full shade.
- Many people plant tulips along fences, walls, walkways, and buildings, as these locations provide an appealing display and more control over growth patterns.
- If you plan to grow tulips in containers, refer to this guide for detailed instructions.
Prepare the soil. Loosen the soil to a depth of 20 to 25 cm and add sand or gravel if necessary.
- Tulips require well-drained soil; damp conditions can lead to mold, disease, and even rot. Excess moisture may also suffocate the bulbs by limiting oxygen. It’s best to plant on raised beds in damp areas.
- Improve soil aeration by adding compost and coarse sand. Additionally, remove any weeds that may have grown in the area.
Plant the tulip bulbs.
Plant the tulip bulbs. Place the bulbs in the ground at a depth of 15 to 20 cm, measuring from the base of the bulb. The larger the bulb, the deeper it should be planted.
- The standard planting depth is 15 cm, but if the weather isn’t too harsh, you can plant them at 20 cm to keep them cool.
- Place the bulbs in the hole with the pointed end facing up. Cover the hole with soil and gently press down to firm it in place.
- Space the bulbs 12 cm apart. To create a tulip bed, plant 5 bulbs within a 90 cm² area. Plant all bulbs at the same depth to ensure they bloom simultaneously.
Repel rodents. If you encounter rodent issues, use repellents such as fly-repellent plastic sheets, cat urine, or place stones in the holes. If repellents are ineffective, you should set up a net to protect the flower bed.
- You can also spread a layer of geotextile fabric over the soil to prevent moles and other rodents from digging up the tulip bulbs.
Water thoroughly after planting the bulbs. Do not water again until the shoots start to appear. Although tulip bulbs don’t thrive in overly moist conditions, initial watering is necessary to trigger growth.
Cover the flower bed with straw to keep the soil cool. In areas with mild winters, apply mulch immediately after planting the flowers. In colder regions, wait for 3 to 4 weeks after planting before adding mulch, allowing the roots to establish before the soil freezes.
Plant tulips in pots
Plant tulips in containers. Choose a pot with a minimum diameter of 50 cm and height of 40 cm. You can plant 18-22 tulip bulbs, spacing them about 3 cm apart, so they are almost touching each other.
- Container-planted tulips should be planted in late fall, just like garden tulips.
Water after planting. Only water the tulips once after planting, and do not water again throughout the winter. When the leaves start to sprout in the spring, you can begin watering lightly.
Protect the plants during winter. Place the tulip pots in a well-ventilated garage, shed, or a sheltered location during winter. When the plants begin to sprout in early spring, you can move them outdoors.
Care for tulip flowers
Wait for the flowers to bloom. Let the bulbs develop naturally throughout the winter months—no need for watering or fertilizing. When spring arrives, they will bloom all at once, showcasing vibrant colors.
- Tulips are perennial flowers, meaning they bloom every year. However, in most parts of North America, the weather and soil conditions prevent the bulbs from growing back, so they only bloom once a year before stopping.
- If you live in an area where tulips can bloom year after year (ideal conditions are dry summers and cold winters), check out the guide below for more tips.

Plant tulip bulbs in the ground to allow them to naturally multiply. Tulip bulbs can easily multiply if left undisturbed in the soil for a full year. If desired, you can transplant new tulip bulbs to different locations where you wish to see tulips bloom.
Follow a proper watering schedule. Once the tulip bulbs begin to develop, you should start watering to prevent the soil from drying out. However, avoid overwatering as it can harm the bulbs.
- Continue watering even when the flowers stop blooming. The bulbs still grow underground for the following year. Allow the leaves and stems to keep growing until they naturally wilt and die off.
- Stop watering the bulbs once the leaves have fallen and allow the soil to dry. The plant no longer nourishes the bulb, and tulips require dry conditions during the summer months.
Remove the flower heads. Cut off the spent flowers after three weeks of blooming, before the petals begin to fall. If the petals fall to the ground and get stuck in the leaves, they can cause mold and harm the plant, preventing the bulb from properly developing underground.
Fertilize in the fall. To grow tulip flowers year after year, apply a low-nitrogen fertilizer in the fall, such as compost or specialized flower bulb fertilizer.
- If you forget to fertilize in the fall, you can still fertilize in late winter or early spring, once the new shoots begin to grow. Use a high-nitrogen, fast-release fertilizer for the best results.
Keep tulip flowers fresh for longer. To make sure the cut tulip stems last longer in a vase, trim the stems at an angle and wrap two-thirds of the flower heads with newspaper in a funnel shape.
- Soak the flowers in cool water for one to two hours, then remove the newspaper and trim the stems again.
- The flowers should remain fresh for about a week.
Advice
- Plant tulip bulbs, like other flowers, about 20 cm deep to prevent ground squirrels from eating the bulbs. These rodents typically burrow about 10 to 15 cm underground.
- Dig up the bulbs after the plants die and store them in a cool, dry, dark place throughout the summer if you plan to replant them for the next season. This step is only necessary if the summer is particularly humid or if you're planting in a low-lying area prone to water retention.
