The bulb, essentially the tulip’s root, is named for its round shape. It’s unique in that it must undergo a period of cold treatment before planting. When purchasing bulbs from a florist or online, it’s crucial to confirm whether they have been cold-treated.
When buying bulbs, you can also purchase some soil. Tulips thrive in sandy soil that is rich and airy. After purchasing, it’s necessary to disinfect the bulbs by soaking them in formalin for half an hour to prevent disease and pests. After disinfection, peel off the brown skin of the bulb to enhance its survival.
During planting, lay a layer of sandy soil at the bottom, then insert the bulb vertically into the soil, about half as deep as the bulb itself. Don’t overcrowd the bulbs in the pot; for a pot about twenty centimeters in diameter, it’s recommended to plant three bulbs.
As you add soil to the pot, gently press around the edges to secure the bulbs, being careful not to damage the delicate center of the bulb, which can affect germination. After filling the pot, thoroughly water it. Maintain moist soil and patiently wait for the tulips to germinate.
Tulips prefer soil that is rich in organic matter, well-draining, and loose. Slightly acidic sandy loam is generally best, promoting healthy tulip growth.
Tulips can be fertilized with mature organic fertilizer, cake fertilizer, and bone meal. However, tulips are sensitive to fertilizers, so it’s best to fertilize 2-3 times from early spring when the stems and leaves extend and buds appear.
The soil’s moisture level must be regulated when growing tulips, kept semi-dry and semi-moist. Maintain a certain degree of humidity during the growth period with no need for watering, just keep the soil moist. When the weather is dry, water 1-2 times to a depth of about 15 centimeters.
Tulips need at least 8 hours of sunlight each day. This aids the tulips’ photosynthesis, ensures healthy plant growth, and promotes normal blooming.
Tulips, as long-day plants, love sunlight. They can be grown on a balcony, but wind protection is necessary. As long as the temperature remains above 8℃, tulips will grow well.
The optimal temperature for summer growth is 20℃-25℃. If the temperature gets too high, move the tulips indoors. In winter, as long as temperatures stay above -14℃, tulips can survive without freezing, making them very easy to care for.
