Select the Healthy Planting Medium

For your tulips to sprout and produce lovely buds, you must select the appropriate planting medium. The bulbs are purchased from gardening stores or nurseries. When buying tulip bulbs, keep the following in mind.: 

Scales – Make sure the shell isn’t too dark brown and pliable. A firm, dark brown coating indicates that the bulbs have been overexposed in the soil.

Size – The bulb should be 3-4 centimeters in diameter at its widest point. Although smaller buds take longer to germinate, you should purchase them.

Appearance – Make sure your planting materials are in the right form, color, and texture for the job. Check for stains, damage, or any other indicators of illness on your planting supplies. 

Stem – Make sure the stem isn’t too big and doesn’t have any mold on it. Also, notice how the bulb’s tip is the only part that protrudes

Weight – A good bulb has a thick feel about it. If you press it, be sure no liquid escapes. It might be rotting on the inside, based on the light planting material. 

Prepare Your Greenhouse and Soil

To avoid your bulb becoming diseased, you must first prepare the soil to be:

  • Permeable to light and water
  • A mixture of sand and sawdust in equal parts
  • Drainage materials such as fine gravel or shell rock can be used.

To disinfect the soil, 

  • Calcine the soil for 14 hours at maximum temperature to sterilize it.
  • Allow chilling in potassium permanganate solution

Plant the bulbs in 15-cm-deep broad boxes. By immersing them in a dark pink potassium permanganate solution or pouring hot water over them, they can be disinfected.

Sulfurize your greenhouse and clean the walls with a copper sulfate solution (1 tbsp. l. 10 gallons of water).

Prepare Your Planting Material

Before you start planting, make sure you have all of your planting materials ready by:

Calibration – Sort your bulbs and inspect them for stains and damage before planting. Because smaller bulbs germinate later than bigger bulbs, they are planted several days later.

Cooling – The bulbs are put in a chamber with a temperature of 9 ° C for two weeks to help them germinate quicker.

Cleaning -Brown husks are scraped away from the bulbs. The bulbs are examined for damage and stains to assure the quality of the planting material and to speed up germination.

Disinfection -The planting material is steeped in a dark pink potassium permanganate solution for 40 minutes.

Growing Care for Your Tulips

If you want to sell your tulips while they’re in high demand, you should take the following steps.


For the first two months, the greenhouse is shaded, since the planted bulbs must be maintained in the dark. Tulips get ample natural light till February. After that, the plants are given 12 hours of daylight.


Maintain a temperature of 7 to 9 ° C in the greenhouse for the first two months after planting. The temperature is then raised to

  • 18  to  17 ° С during the day  
  • 14  to 15 ° С at night

When tulips bloom, the temperature is reduced to  15 ° C.


Tulips thrive in humid environments. Ensure that the greenhouse’s walls are sprayed every day to offer them the best possible environment.


Every day, irrigate your tulips with water that is 8 to 12 degrees Celsius.


Alternate your watering and feeding for the first two weeks. 20 g calcium nitrate, diluted in 10 liters water, should be given. Throughout the growing season, feed your plants twice using specific fertilizers.

Correct Harvest

The quality of the cut determines how long the buds will stay fresh and if the bulbs will be appropriate for planting the next year

You have three options to harvest your tulips: 

  • Cut tulips very  low with leaves 

If you do not plan to use the bulbs for planting next season 

  • Cut tulips with the ground part with a height of at least 7 to10 cm remaining in the ground. 

This will make them suitable if you are planting next year. 

  • Dig up with the bulbs 

Then the bulbs on the tulips are washed clean from the ground. These flowers will stay fresh for a much longer time


Growing tulips in a greenhouse necessitate continual care from the plant’s owner. This is to provide a consistent temperature, adequate humidity, and correct watering.

Despite this, even a novice flower farmer will be able to cultivate tulips. The most important thing is to stick to the planting and maintenance instructions.
