A Detailed Guide to Hydroponic Tulip Growing: Beginners Can Learn It Easily

1. Buying materials

Growing tulips hydroponically is a technical job, and sharpening the axe does not delay the woodcutting, so the first thing to do is go shopping: buy the equipment needed for hydroponic tulips and, most importantly, the tulip bulbs.

2. Disinfection

Disinfection is a necessary step for hydroponic plants, and it is also the starting point where hydroponic tulips go from beginner to giving up. First, buy chlorothalonil from a shop or on Taobao. If used directly, chlorothalonil is too concentrated, so it must first be diluted with water. By the way, tulip bulbs are not much to look at, so do not let that discourage your confidence in growing tulips. After diluting with water, throw the tulip bulbs into the chlorothalonil solution and soak them for about thirty minutes or so.

2. Soaking

After scooping out the tulip bulbs with a water ladle, drain off the water and place the tulip bulbs into the hydroponic box. Do not use too much water; it should just cover the base of the bulbs and touch the skin of the bulbs.

4. Temperature

Tulips like light, so the hydroponic box should be placed in a spot with plenty of light, but the suitable growing temperature for tulip bulbs is on the low side, so pay attention to where you place the tulip bulbs.

5. Watering

Tulip bulbs have high water requirements. During the bulb growth period, the demand for water is relatively large, so change the water every two or three days, but do not change all of it; changing part of it is enough.

That is all for the introduction to hydroponic tulip methods. If you want to give it a try, get started, but there are also some points to note during the hydroponic process, so be careful!

Hydroponic Methods for Tulips

Tulips are very precious spring flowers. Whether grown in pots, planted in courtyards, or used as cut flowers in vases, they are all very beautiful and charming. Tulips are one of the flowers most loved by gardening enthusiasts, and many friends have asked how to grow tulips. So let us learn about tulip cultivation methods together below, and we hope it will be helpful to you.

Sharing Experience with Hydroponic Cut Tulips

Tulips belong to the Liliaceae family as perennial herbaceous plants, and they are popular because of their large flowers and brilliant colors. China began introducing and experimentally cultivating them in the 1990s. At present, the main domestic hydroponic experience is as follows:

1. Choosing suitable and disease-free bulbs is the key to hydroponic production of cut tulips. According to the time when flowers are needed, choose and determine the cultivation time and planting method. For hydroponic cut flower cultivation, the bulbs should be planted in disinfected and leak-proof needle trays, keeping the rooting temperature stable at 8°C and the humidity between 60% and 70%, and spraying New High Lipid Film to preserve moisture and prevent pests and diseases.

2. After about two weeks of rooting, make sure the roots are more than 3 cm long, then move the needle trays into the greenhouse. Control the temperature at 15°C to 20°C and the humidity at 60% to 70%, add nutrient solution so that the Ec value in the water is 1.5 ms to 2.0 ms, and spray Zhuangjingling to make the tulip stems and leaves grow rapidly.

3. In the early growth stage, to prevent diseases caused by filamentous fungi, spray targeted chemicals plus New High Lipid Film 2 to 3 times. Spray foliar fertilizer at the appropriate time according to the growth situation to coordinate vegetative growth and reproductive growth, and spray Huaduo Zhuangdiling at the appropriate time to make the flower buds strong, the petals plump, the flower colors brilliant, the fragrance rich, and the flowering period longer. During the growth process, change the water 2 to 3 times.

How to Make Tulips and Hyacinths Bloom Year After Year

1. Disinfect the bulbs by soaking them in 1000 times diluted thiophanate-methyl for 20 minutes, then plant them in an already prepared container, covering them with 4 cm to 5 cm of soil. After planting, place them in an environment of about 9°C, and rooting will begin in about 15 days.

2. Place the rooted bulbs under conditions of 15°C to 18°C to promote flowering, and they can bloom after 50 to 60 days.

3. Regulate the flowering period and understand the characteristics of the variety, that is, the growth periods of different early, middle, and late varieties. Count backward from the flowering date, which is the starting date of the flowering promotion period.

4. Store the bulbs that have already bloomed well, place them in a relatively cool environment to keep them in good growing condition, and cut off the flowering branches. Be careful to apply decomposed fertilizer in time to make the bulbs plump. Pay attention to pest and disease control throughout the growing season.

5. In late autumn, when the weather gradually turns cold, place the pot outside to let it sprout again. For bulbs that have already sprouted, simply repeat step 2, and they will bloom again when needed.

6. For bulbs that have not undergone low-temperature treatment, place them in a naturally cool environment for low-temperature treatment after potting, and promote flowering after the bulbs sprout.

Key Points for Tulip Cultivation and Management

Tulips are long-day flowers and prefer a sunny, wind-sheltered climate, with warm and humid winters and cool and dry summers. They can grow normally above 8°C and can generally tolerate low temperatures of -14°C. They are very cold-hardy; in severe cold regions, if there is thick snow cover, the bulbs can overwinter in the open field, but they fear intense summer heat. If summer comes early and midsummer is very hot, the bulbs are difficult to carry through the summer after dormancy. They require slightly acidic sandy loam rich in humus, loose and fertile, and well-drained. Avoid alkaline soil and continuous cropping.

Late September to November (1) Soil preparation: Choose sandy loam rich in humus and well-drained, apply sufficient organic fertilizer, and avoid heavy, clayey, low-lying alluvial soil above all. For pot cultivation, use garden soil: leaf mold: sand at 5:4:1 to prepare the growing medium, and mix in a small amount of dried chicken manure, bone meal, and so on.

(2) Planting: During this period, tulip bulbs can be planted throughout the Yangtze River basin. The planting depth is generally 2 times the height of the bulb, with a plant spacing and row spacing of 9 cm x 10 cm. For pot cultivation, broken tiles and so on should be laid at the bottom of the pot to facilitate drainage. After planting, spread grass and water thoroughly to promote rooting. Note that the bulbs need to be disinfected before planting, soaked in thiophanate-methyl or potassium permanganate solution for 15 minutes, or fumigated with formalin; the soil should preferably also be disinfected by watering with formalin and covering.

(3) Bulb treatment for forcing cultivation: If you want tulips to bloom earlier, the bulbs need to be cold-stored in early August, generally pre-cooled at 13-15°C for 2-3 weeks, then cold-stored at 2-5°C for about 8 weeks. Storage at 5°C is suitable for most varieties. Some varieties can be treated with the 9°C moist-cooling technique, in which they are cold-stored at 9°C for 12-16 weeks, and during the last 6 weeks the bulbs need to be planted in wooden boxes or plastic boxes, watered, and then placed in a 9°C cold storage room, where the plants root and sprout.

December to February of the following year (1) Management of natural cultivation: After tulips root, they go through a natural low-temperature stage. During this period, keep the soil moist. After leaves begin to emerge in early February, weed the field in time. (2) Management of forcing cultivation: Forcing cultivation must be kept warm and heated in a plastic tunnel or greenhouse. The optimum temperature for tulip growth is 15-18°C. When the temperature drops below 5°C, tulips stop growing and need heating; however, when the temperature and humidity are too high, they are prone to leggy growth as well as mildew and deformed flowers, so attention should be paid to ventilation in the protected area, and day and night temperatures should not exceed 25°C. Once diseased plants are found, they should be removed and burned in time. In 5°C forcing cultivation, it takes about 50-60 days from planting to flowering; for 9°C box cultivation, the greenhouse time is only about 25 days.

March to May (1) Fertilizer and water management: After 2 leaves have emerged, apply 1-2 times of dilute liquid fertilizer or compound fertilizer as topdressing. After flowering in late May, apply 1-2 times of potassium dihydrogen phosphate or compound fertilizer as topdressing to help the underground bulbs expand and develop. (2) Flowering period management: Tulips generally bloom in full from late March to late April. During the flowering period, fertilizer and water should be controlled, and measures such as rain sheltering and shading should be used to extend the flowering period. The natural flowering period of tulips is only about 2 weeks, and pot cultivation especially needs to avoid direct sunlight, otherwise the flowering period will be very short.

June to August (1) Harvesting bulbs: After the leaves have basically turned yellow and withered, dig up the bulbs on a dry sunny day. Be careful not to damage the bulbs when digging, otherwise the wounds are very likely to become infected and rot. After digging them up, remove the leaves, separate the bulbs by size, and place them in a shady place to dry thoroughly. If dried in strong light, they are also prone to disease. (2) Bulb storage: Spread the bulbs out appropriately and store them under well-ventilated conditions at 20-25°C. High summer temperatures will affect flower bud differentiation inside the bulbs, because the optimum temperature for tulip flower bud differentiation is 17-23°C. During the plum rain season, pay special attention to ventilation and coolness in the storage room.

Can Tulips Be Grown Hydroponically? Hydroponic Tulip Methods

Some people may know something about hydroponic flowers, but do you know whether tulips can be grown hydroponically? Below we will explain hydroponic tulip methods.

Can tulips be grown hydroponically?

Hydroponic tulip methods:

1. Bulb selection: Choosing suitable and disease-free bulbs is the key to hydroponic production of cut tulips. Hydroponic tulips require cold treatment of the bulbs. Before the end of October, control the temperature at 9°C, then gradually lower it, and from December to January keep the temperature at about 2°C and the humidity at 85-95%.

2. Planting method:

(1) According to the time when flowers are needed, choose and determine the cultivation time and planting method. For hydroponic cut flower cultivation, the bulbs should be planted in disinfected and leak-proof needle trays, keeping the rooting temperature stable at 8°C and the humidity between 60% and 70%.

(2) After about two weeks of rooting, make sure the roots are more than 3 cm long, then move the needle trays into the greenhouse. The relevant greenhouse conditions are: humidity at 60%-70%, adding nutrient solution so that the Ec value in the water is 1.5 ms to 2.0 ms, and temperature controlled at 15-20°C. Such values favor the rapid growth of tulips.

(3) The early growth stage is very prone to disease, so in the early growth stage, to prevent diseases caused by filamentous fungi, spray chemicals 2 to 3 times. Choose low-toxicity agents, thiophanate-methyl, highly effective chlorothalonil, Tuzet, and so on, with a concentration between 750 and 1000 times dilution.

(4) Spray foliar fertilizer at the appropriate time according to the growth situation to coordinate vegetative growth and reproductive growth. During the growth process, due to root secretions and other environmental conditions, an oil film will form on the water surface of the needle tray. This will cause the root system to lack nutrient supply, leading to the roots turning brown. Therefore, change the water 2 to 3 times as needed.

3. Nutrient solution: Place the planting trays in a rooting room at 5°C with a small amount of air circulation. Replenish water at the appropriate time. Tap water or rainwater with a conductivity value of 1.5 ms/cm can be used. For varieties prone to leaf splitting, water with a conductivity value of 2 ms/cm should be used during the rooting stage.

4. Care: When tulip roots grow to 100px, place the planting trays on a relatively flat ground in the greenhouse and remove diseased bulbs or bulbs that have not sprouted. At this stage, make sure the water level reaches the overflow outlet, keep the temperature at 16-18°C, and maintain the humidity at 60-80%. At the end of planting, the frequency of watering can be reduced to half of the previous amount. Before harvest, sufficient water should be provided to the plants, which can extend the tulip flowering period.
