What season do tulips bloom?
In-depth Interpretation of Tulip Blooming Season
Natural blooming规律
Tulips usually bloom from March to May, with different varieties having different blooming periods:• Early blooming varieties (such as single petal early blooming) start to bloom in early March• Mid blooming varieties (victory type) enter full bloom in April• Late blooming varieties (parrot type) can continue to bloom until late May
Climate influence mechanism
Temperature and light together regulate the flowering period:• In the north, the spring cold delays the flowering• The warm winter in the south may cause the flowering period to be 1-2 weeks earlier• Greenhouse cultivation can achieve accurate flowering control for festivals such as New Year's Day and the Spring Festival
Scientific Maintenance System After Tulip Blooming
Accurate pruning skills
• Retain the flower stem: cut obliquely 2cm below the withered flower, retain 40% of the stem for photosynthesis• Leaf treatment: prune close to the ground after natural yellowing to avoid premature damage to the bulb• Tool disinfection: wipe the scissors with alcohol to prevent bacterial infection
Full process of bulb treatment
• Timing of digging bulbs: 3-5 days after the leaves are completely withered• Grading and screening: diameter >12cm is super grade bulb, 9-11cm is commercial grade bulb• Disinfection and storage: soak in carbendazim and dry in the shade, store in vermiculite substrate at 15℃
Key technologies for replanting
• Substrate formula: peat soil: perlite = 3:1, pH value 6.0-7.0• Planting depth: 3 times the diameter of the bulb (usually 8-10cm)• Vernalization treatment: 4-6 weeks of 5℃ low temperature stimulation in winter for flower bud differentiation
Through systematic maintenance and management, tulip bulbs can maintain high-quality flowering characteristics for 3-5 consecutive years. It is recommended to establish a maintenance log, record the changes of phenological period every year, and gradually form a personalized cultivation system, making the spring flower sea an eternal landscape of the courtyard.
