Does Planting Need Species Tulips To Be Refrigerated?

Tulip bulbs can be stored in the refrigerator before planting, but it is important to keep them in a paper bag or mesh bag to prevent moisture buildup. The temperature should be between 40-70ºF (4-20°C). A place like a basement or garage is ideal for storing tulip bulbs. Not all tulip bulbs are suitable for storage in the refrigerator, and species tulips, such as Tulipa clusiana or Tulipa kaufmanniana, generally do not require chilling and are best planted in outdoor storage areas.

The longevity of tulip bulbs varies depending on the climate. In cold climates (USDA hardiness zones 4 to 7), bulbs need a chilling period of about three months to re-bloom. In zones 8 to 10, bulbs need to be prechilled in a refrigerator at temperatures between 38 and 45 degrees F. However, they still need to be refrigerated for 6-8 weeks before planting.

For home gardeners, winter frosts do not necessarily require refrigeration, but in warmer areas of New Zealand, many tulip cultivars may need refrigeration before planting. It is also important to keep the place well ventilated, so it is not recommended to keep bulbs in the refrigerator or an airtight plastic bag.

Tulip bulbs need a dormant period to bloom, so it is not optional. They can be planted once the soil has cooled down to around 55°F after two weeks of sweater weather. If living in mild winters (USDA plant hardiness zones 7b or 8, and south), tulip bulbs will need to be chilled for many weeks before planting. In this process called prechilling, the bulbs are stored in a refrigerator or cooling unit (never the freezer) between 35 degrees F and 40 degrees F.

Which bulbs need to be refrigerated?

Spring-blooming bulbs like tulips, crocus, hyacinths, dafodils, muschi, snowdrops, alliums, and iriss require chilling before planting. In northern regions, they can be planted directly in the ground in fall, and then in the winter, the ground gets cold. However, in Houston, the cold doesn’t get too cold, so the bulbs need to chill themselves. Non-tropical plants have natural cycles of active growth and dormancy that align with their environment’s weather patterns.

Winter cold coaxes flowering bulbs into a hibernation, signaling them to bloom when temperatures start to rise. This prevents them from being covered by a big snow dump, which is not enough to knock out cold-hardy spring flowers like the crocus. To successfully grow these flowers in late autumn or early spring, the chilling process must be controlled to trick them into thinking it’s winter.

How do you force bulbs without chilling?

To sprout early-season blooming bulbs like tulips, narcissi, and crocus, you may need to provide a cold treatment. Summer blooming varieties can be forced without chilling, but spring bulbs need a cold period followed by warmth to break dormancy. To force bulbs without chilling, start them indoors in pots with a good bulb mixture of soil, peat, and perlite. Plant the bulb with the pointed end up and the flatter end at the bottom of the hole.

Spring-blooming bulbs need a warm location inside and average water. Most spring bulbs come pre-chilled, but if you have over-wintered them indoors, you can mimic the cold period by placing them in peat moss and refrigerating them for three months.

What is the cold treatment for forcing tulip bulbs?

Spring-blooming bulbs require a chilling period of 12 to 15 weeks to develop a well-developed root system, stems, and flower buds. They typically take 2 to 4 weeks to grow and bloom once removed from the cold treatment. To have bulbs in bloom during winter, plant them and start the cold treatment in early fall. Potting should occur by the beginning of September for mid-December blooms, and mid-October for Valentine’s Day blooms.

While there is no strict maximum number of weeks they must be in cold storage, pot all bulbs at the same time in the fall and remove them over a 2 to 4 week period in the winter after the minimum 12 to 15 week chilling time has been met. Most bulbs are forced in a well-drained, commercial potting mix, and any container with one or more drainage holes and is twice as deep as the bulbs to be planted can be used for forcing.

Do tulip bulbs need to be refrigerated before planting?

Order bulbs before September to receive delivery in October. Store them in the refrigerator for 6-12 weeks, depending on your location. Plant between late November and early January, not after mid-January. Colorblends offers prechilling for bulbs exceeding two crates, which is equivalent to 1200 tulip bulbs. The prechilling service is charged at a flat fee of $50 per order, covering handling and electricity costs. Space in the cooler is limited, so it’s best to use the space for prechilling.

Can you force tulip bulbs in the fridge?

Tulips and other spring-flowering bulbs require a chilling period of 40 to 45 degrees Fahrenheit for 12 to 16 weeks to bloom. They can be stored in a refrigerator, root cellar, or outdoor trench. During cold storage, water the bulbs regularly and keep them in complete darkness. Once the cold requirement is met, remove the potted bulbs from the cold storage, allowing yellow shoots to emerge. Place the bulbs in a cool location with low to medium light for 4 to 5 days, then move them to a brightly lit location.

Water the plants regularly and turn the containers regularly to promote straight growth. Flowering should occur 3 to 4 weeks after removal from cold storage. For a succession of bloom indoors, remove pots every 2 weeks.

Why do tulips need cold?

The life cycle of a tulip bulb involves several years of growth, root formation, and a period of ‘dormancy’. The tulip needs a cold period to stimulate growth of the stem, leaves, and floral bud. In spring, the flower stem elongates and the flower bud appears. The mother bulb is used up after flowering and replaced by a daughter bulb. Once warm summer temperatures arrive, the leaves die back, the floral bud develops, and the bulb enters dormancy again.

Temperature is crucial in the life cycle of the tulip. Warm summer temperatures stimulate the development of the floral bud, while cold temperatures break dormancy and trigger growth. However, warm springs can negatively affect the quality of the flowers the following year. The bulbs are at a more advanced stage when harvested and stored, leading to dehydration of the flower bud.

As temperatures increase and winters become milder, growing crocus, tulip, and hyacinth becomes more difficult due to the lack of chill factor. However, they can be grown in climate change gardens with 6 to 8 weeks of chill to trigger the flowering cycle.

Do tulips need to be chilled?

Tulip bulbs should be pre-chilled for 6-14 weeks, depending on the location. Over-cooling can lead to stunted growth and shorter stems, deformed blooms, or lower-down flowers. To ensure successful flower development, plant bulbs in the fall or early winter at the latest. If you cannot get them in the ground immediately, place them in a cool, dark, well-ventilated location for an additional few weeks.

The ideal time to plant pre-chilled bulbs is late November or early December, with planting recommended no later than January 1st. In warm climates, un-cooled bulbs may have shorter stems and deformed blooms. Planting bulbs in a cool, dark, well-ventilated location is recommended for optimal results.

Do daffodils need to be chilled before planting?

In south Louisiana, tulip and hyacinth bulbs require pre-chilling before planting, typically eight weeks. Daffodil, narcissus, and Dutch iris bulbs can be refrigerated and planted later, but it’s not necessary. Spring flowering bulbs don’t require pre-chilling and are typically planted from late October to early December. Tulip and hyacinth bulbs that are chilled in a refrigerator for eight weeks are planted in late December or early January after the soil has cooled down.

How long do tulips need to chill before forcing?

To ensure the growth of Tulips, it is recommended to chill their pots for 12 to 14 weeks, ensuring they are prechilled to develop good root systems and anchor the bulbs into the soil. Avoid stacking the pots on top of each other to avoid stunting sprout growth. After the cooling period, bring the pots out into filtered sunlight for three to five weeks, watering as needed. Once the buds emerge, move the pots into direct sunlight in a temperature range of 50°F to 65°F.

Once the buds color up, the pots can be placed anywhere for maximum viewing and enjoyment. Remember that the cooler the ambient temperature, the longer the flowers will thrive. Once the bulbs are forced, they are spent and should be discarded.
