How to Grow Tulips From Bulbs: Planting and Care

To grow tulips from bulbs, plant them in fall, several inches deep, in full sun and well-drained soil, and leave them alone through winter. Penn State says spring-blooming bulbs go in before the first frost, and Clemson says to wait until the soil at planting depth stays below 60°F (16°C). The flowers come in middle to late spring (NC State). The catch is the second year: tulips are happiest where winters are cool and moist and summers are warm and dry, and in warmer places they are treated as annuals. Do not count on a second season everywhere.

Can you grow tulips where you live?

NC State says tulips grow best in areas with cool, moist winters and warm, dry summers, and that the plant is intolerant of heat and loses floral vigor when soil temperatures reach 70°F (21°C). Our sources give no USDA zone range for garden tulips. The only range we have, zones 3 to 7, is for the lady tulip (Tulipa clusiana), a species, and NC State says it performs best there with moist winters and warm dry summers.

In the warm South the advice changes. Clemson says tulips can usually only be counted on for a single season of color in South Carolina and are treated like annual flowers, dug and discarded after they bloom. Clemson also says to refrigerate bulbs from the time of purchase until planting in November to late December to ensure spring flowering in Central and Coastal South Carolina. Tulips also have a chilling requirement, and we cover the hours in our guide to forcing tulips in pots.

When to plant tulip bulbs

Plant in fall. Penn State says spring-blooming bulbs are planted before the first frost for an early to late spring or early summer bloom. Clemson says to wait until the soil temperature at planting depth stays below 60°F (16°C), except for daffodils, which go in October or November. Our guide to when to plant tulip bulbs has the soil-temperature rule, the regional dates in our sources and the chilling times.

How deep should you plant tulips?

The sources give three different rules, and they are not identical.

The first two are multiples and the third is a fixed figure. They line up if your bulb is about 2 inches (5 cm) tall: three times that is 6 inches, which is the shallow end of Clemson’s range. That is our arithmetic, since our sources do not give a bulb size. For a larger bulb, use the multiple, which scales with size, rather than a fixed number.

Planting steps

1. Pick a site with full sun and drainage. NC State says tulips want full sun (6 or more hours) and fertile, organically rich, well-drained, medium-moisture soil. Clemson says good drainage is essential and the soil pH for most bulbs should be between 6 and 7.
2. Wait for cool soil. Clemson says to plant when the soil temperature at planting depth stays below 60°F (16°C), with no source giving a date for all regions.
3. Plant at the right depth. Use the multiple that fits your bulb, or 6 to 8 inches (Clemson). Space bulbs 4 to 6 inches apart (Clemson).
4. Water if the fall is dry. Clemson says normal rainfall usually provides enough moisture for spring-flowering bulbs. In a hot or dry spring it says extra water helps prolong blooming. Our sources give no fall watering amount.

Tulip care after planting

Which tulips to grow

Clemson recommends two groups. It calls the Single Late tulips one of the best groups for growing in warm climates. It also names the Lily-flowered group.

Why tulips do not always come back

NC State says tulips may be grown as perennials or annuals, and that species tulips often perform better than hybrid plants as perennials. Clemson says the garden hybrids are treated as annuals in South Carolina. If you want a repeat show, you have two options in our sources: choose a species such as the lady tulip, or plan to replant every fall. Our full explanation, including the other reasons a tulip may skip a year, is in why tulips do not come back.

Common tulip problems

NC State also lists tulip break virus, gray mold and mosaic virus as problems that may occur. It gives no treatment on the page we used.

Tulips in pots

NC State says tulips make wonderful outdoor container plants and can also be forced in containers as florist plants for indoor displays. Forcing needs a long cold period: 15 to 17 weeks by Penn State and UW-Madison, 12 to 16 weeks by Clemson. See our guide to tulips in pots and forcing.

Safety

NC State says tulip bulbs are toxic, with tulipalin as the toxic principle and the highest concentration in the bulb. Its species page recommends wearing gloves when handling bulbs to prevent skin allergies. Our sources do not rate tulips for cats or dogs.

What our sources do not tell you

They give no USDA zone range for garden tulips, no month-by-month planting dates for most regions, and no fall watering amount. They do not explain why hybrids decline, only that they often do.

If you like bulbs, calla lilies are the summer counterpart: planted from rhizomes in spring and dug in fall in cold climates. Our calla lily care guide has the details, and the overwintering guide shows how to store them.
