How to Solve Yellowing and Dropping Leaves in Potted Tulips

Although the tulips we know best mostly exist in the form of flower fields, it is of course impossible to rule out the situation of tulip lovers keeping them as treasured houseplants. As the number of tulip lovers increases, potted tulips have gradually entered countless homes, but not everyone has mastered the techniques and methods of growing tulips, so problems are unavoidable during the growing process.

What to Do When Potted Tulip Leaves Turn Yellow

1. Pest and disease control, division and transplanting

Clean up withered leaves promptly and make sure there are no dead leaves on the ground.

Pests and diseases are mainly fungal infections, so use a disinfectant to sterilize, or directly spray diluted pesticide.

If the plants are too dense, divide and transplant them to ensure there is some space between plants and good ventilation. If they are potted, move them to a ventilated place for care whenever possible.

2. Fertilizing and watering, reasonable temperature control

If the soil is too dry or too waterlogged, the plants will show sickly symptoms, so water reasonably, watering when dry and letting it dry out between waterings. Tulips in the garden should not be irrigated on a large scale; spray them instead whenever possible.

Fertilizing should mainly use liquid fertilizer. Apply diluted liquid fertilizer once a week, and during the period when leaves are yellowing, phosphorus fertilizer can be appropriately increased.

Control the temperature reasonably. When the temperature reaches above 20°C, sprinkle water around the plants to cool them down.

How to Solve Leaf Drop in Potted Tulips

1. Viral diseases

There are many viruses that harm tulips, and two common ones are mosaic virus and color-breaking virus.

Mosaic virus causes affected leaves to develop yellow stripes or granular spots, and dark spots to appear on the petals. In severe cases the leaves rot. Pay attention to timely control of aphids and removal of weeds.

Color-breaking virus causes diseased leaves to develop pale yellow or grayish-white stripes or irregular spots, sometimes forming a mosaic pattern, and light yellow or white stripes or irregular spots appear on the petals, producing broken-color flowers on red or purple varieties. Its control method is the same as for general viral diseases, but the planting site must be kept away from lilies.

2. Lighting problems

Within more than half a month after tulips are potted, they should be properly shaded to help the bulbs develop new roots.

Sufficient light is essential for tulip growth. Insufficient light will cause poor plant growth, causing bud drop, weakened plants, lighter leaf color and a shortened flowering period.

3. Fertilizing problems

Tulips quite like fertilizer, so sufficient base fertilizer should be applied before planting. Generally, dried chicken manure or decomposed compost is used as base fertilizer, followed by thorough irrigation. Plow and harrow carefully 2-3 days before planting to ensure the soil is loose. After the bulbs produce two leaves, apply liquid fertilizer 1-2 times as a top dressing. During the peak growing season, apply a compound fertilizer balanced in nitrogen, phosphorus and potassium 3-4 times a month. Stop fertilizing during the flowering period, and after flowering apply liquid fertilizer of monopotassium phosphate or compound fertilizer 1-2 times.

4. Soil problems

For tulip cultivation, sandy loam is best, and the soil pH should be neutral to slightly alkaline; acidic soil must not be used.

5. Watering problems

During tulip cultivation, never over-irrigate, but within one week after planting the water requirement is relatively high and they should be watered thoroughly. After germination the water requirement decreases, especially during flowering when water must not be excessive. Watering should follow "small amounts, many times". If it is too dry, growth will be significantly delayed. During the tulip growing period, the air humidity should preferably be kept at around 80φ.

What to Do When Tulip Bulbs Rot

1. Tulip bulbs are dug up too early

Tulip bulbs are dug up relatively early, and the growth of the new bulbs is not yet full. In order to improve the quality of the new bulbs, during the flowering period the plants must receive sufficient light, and quick-acting fertilizer mainly based on phosphorus and potassium fertilizer should be applied. When digging up the plant bulbs, this should be done before the leaves turn yellow.

2. Tulip bulbs are stored at too high a temperature

When storing bulbs, the temperature should not be kept too high, nor the humidity too great. The suitable storage temperature is around 15-20°C, and they should be placed in a well-ventilated indoor spot. If the indoor temperature is too high, the humidity too great, and ventilation poor, it is very easy to cause bulb disease and rot.

3. Tulip bulbs are too wet

New bulbs carrying pathogen-laden soil or not dried properly will lead to bulb rot. After digging them up, remove the original soil they carried, and place them in a cool, ventilated place to wait for the bulbs to dry, then grade them and put them into paper bags or place them on ventilated, breathable shelves for storage and care.

4. Tulip bulb soil is too clayey

When planting, keep the soil from being too clayey and use soil with good drainage. Pay attention to drainage during cultivation. Do not water too much at ordinary times; keep the planting layer moist and loosen the soil frequently so that the soil has good aeration.

What to Do When Tulips Never Sprout

1. Disinfection

If you want tulips to sprout, choosing good bulbs is very important, and then the bulbs must be disinfected. Before planting, this disinfection step is indispensable. Formalin can be used as the disinfectant, soaking for about half an hour; after taking them out, they need to be dried before planting.

2. Soil selection

Next, the bulbs should be planted in fertile sandy soil. Note that the soil layer must be thick and the soil permeability must be good. When planting tulips, also pay attention to the soil temperature; generally plant when it is below 12°C, as this is most favorable for germination.

3. Fertilizing

After planting, an appropriate amount of fertilizer should also be applied, so that there is enough nutrition to promote tulip germination. Fertilizer can be livestock manure or other phosphorus and potassium fertilizers. When the young tulip shoots have just emerged, apply a lower-concentration nitrogen fertilizer once more. 4. Water control

Before tulips sprout, watering is generally not needed; water will cause the seeds to rot. During this period it is enough to keep the soil moist. If the climate is very dry, you can water once or twice lightly; just watering the soil thoroughly is enough. Once the seeds sprout, you can water an appropriate amount every day.
