Tulips are one of the most well known bulbs. They are one of the main cutting spring flowers, available in many shapes, sizes and colors. Because of their beauty they have been a prominent feature in many gardens around the world and have been coveted by gardeners for centuries.

Tulips Description

Tulips are perennials bulbous plant from the genus Tulipa, they grow a few leafs at the base and a long stem with a flower at the end. They can be as small as 10 cm or reach a height as much as 70 cm.

They have fleshy, elongated, waxy coated, light to medium green leafs. Their flowers are colorful and attractive cup shaped with six petals.
Tulips are natives of Central Asia in mountainous areas with temperate climates where they have a period of cool dormancy through the winter.

How to grow tulips

Tulips are classified as perennials, but because of the specific requirements of their native weather, tulips are not the easiest plants to grow as such. They do best in climates with long cool springs and early summers, but are often grown as spring blooming annual plantings in warmer areas of the world. They are typically planted from early September to November and bloom from early Spring through late May.

Is best to pick the healthiest bulbs to guaranty a nice bloom, the best bulbs usually are have a thick fresh glossy body with a smooth surface.

Growing tulips as Annuals

Tulips gather energy in their bulb thought their growing season for the next season bloom. Because of this reason store bought tulip bulbs will most times bloom nicely even if they don’t have the best growing conditions, this means tulips can be treated as an annual plant.

Annual tulips can be planted in a planter or directly into the ground. When planting tulips as annuals they must be planted in autumn from mid September to November, when the temperature varies around 15~20°C. It's best to plant them at least 15 cm deep, but they can stand as little as 5 cm. Also, they need space to grow roots, so they must have at least 5 cm of separation between each bulb. Sandy soil with good drainage and rich in organic matter is best.

Water lightly during the first months when they are growing roots and almost none during their dormancy period on the coolest months. Resume watering once the weather starts to warm again.

Their flowers bloom in spring from March to May depending on their type. If the bulbs are to be discarded it can be done once the flower starts to wither. If it will be saved for another season is best to behead after flowering, but allow the remaining leafs to die off naturally. Once all the leafs have dried the bulb can be dug out and stored on a cool and dry place until the next planting season.

Growing tulips as perennials

While having a tulip bulb bloom one year is relatively easy, having one thriving through the years is a more difficult task. Their native growing conditions must be replicated, otherwise the bulbs will slowly degrade and eventually die.

Having the bulb at an adequate depth is essential, so planting directly into the ground is recommended. The bulb must be set at least at 15 cm depth or three times its height. Also the separation between each bulb must be around 15 to 20 cm. The bulbs must be planted in autumn when the average soil temperature is around 15°C. Sandy soil rich in organic matter is best. Good drainage is essential.

Unless the seeds are wanted is best to behead after flowering, this allows the bulb to concentrate on its own recovery and development for next year's bloom and not use energy in the seeds.

If the weather becomes too hot in summer is best to dig the bulbs once all the leafs have dried and store them in a cool and dry place until the next planting season. If the weather is appropriate tulips will continue to bloom continuously over the years without any need to dig them out, but once every few years is recommended to take them out and separate any new bulb formations to avoid overcrowding.

More Tips for growing tulips
