Detailed Guide to Planting Methods and Steps for Siam Tulip

SummarySelecting high-quality seed bulbs: choose bulbs with a straight stem diameter of more than 1.5cm and more than 3 storage roots. Soil: choose sandy soil with good aeration and drainage. Reasonable close planting: generally plant from late February to early April, first prepare the land and make beds, with about 2 rows planted per bed, and a plant spacing of about 7-12cm. Water and fertilizer: apply sufficient base fertilizer, apply compound fertilizer once every half month after sprouting, pay attention to drainage during the rainy season, and water appropriately if the soil is dry.

I. Select High-Quality Seed Bulbs

1. At present, there are many cut-flower varieties of Siam Tulip, such as Chiang Mai Red, Chiang Mai White, Chiang Mai Pink, Blue Moon, and so on. In addition, there are some potted varieties with relatively tall or relatively short plants. Generally, the pink Chiang Mai Pink is often selected as the cut-flower variety.

2. Before planting, high-quality seed bulbs should be selected. The larger the bulb, the earlier the flowering, and the higher the yield of cut flowers and seed bulbs. Therefore, it is better to choose seed bulbs with more than 3 storage roots and a bulb diameter of more than 1.5cm.

II. Select Soil

Siam Tulip has relatively strong environmental adaptability and grows vigorously. Its roots are relatively developed, and it is suitable for planting in sandy soil with good drainage, strong water retention, good aeration, and deep soil layers. It is not suitable for planting in clay soil.

III. Reasonable Close Planting

1. First, sprout the dormant seed bulbs by placing them in a place at room temperature of about 25-30°C, and they can be planted after about 3 weeks.

2. Siam Tulip is generally planted from late February to early April. Before planting, prepare the land and make beds. The ditch width is about 20-30cm, and the bed width is about 70-80cm. About 2 rows can be planted per bed, with a plant spacing of about 7-12cm, and the planting amount of seed bulbs per mu is about 10,000-17,000.

3. After planting, cover the bed surface with a layer of rice straw to retain moisture and prevent rainwater erosion. Finally, to prevent weeds from germinating too early, butachlor can be appropriately sprayed in the ditches.

IV. Reasonable Water and Fertilizer

1. Before planting, sufficient base fertilizer should be applied. After sprouting, about 25 kilograms of compound fertilizer can be applied per mu each time, once every 10-15 days. The amount and frequency can be appropriately increased or decreased according to leaf color and flower color.

2. The vigorous growth period of Siam Tulip happens to be in the rainy season, so watering is generally not needed. To prevent water accumulation, drainage must be carried out in time. When the soil is dry, it can be watered appropriately.

V. Appropriate Shading

1. For Siam Tulip planted in the open field, the cut-flower length is about 40-60cm. Therefore, in order to reduce green patches at the ends of the flower buds, the shading area needs to reach more than 70cm. A shade net with a shading rate of about 30% can be purchased for shading.

2. In order to prevent the plants from growing leggy, the shade net should be removed in time during the vigorous growth period of the plants; otherwise, it is easy to affect flower quality.

VI. Prevention and Control of Pests and Diseases

The main pests and diseases of Siam Tulip are cutworms, mole crickets, red spot disease, anthracnose, and so on. If diseases occur, pesticides such as methamidophos, carbendazim, thiophanate, dimehypo, and zineb can be sprayed for prevention and control, about once every 15 days. In addition, try to avoid crop rotation with ginger family crops.
