What to do if tuberose only grows leaves but does not bloom

The reason why tuberose only grows leaves but does not bloom

The plant has not yet reached flowering age

The flower buds of tuberose have already formed on the bulbs one year before planting. The reason why only leaves grow but no flowers bloom may be that the planted plants are too small and have not reached the flowering age, so they do not bloom.

Digging bulbs at the wrong time

The bulbs are dug out too early and the flower buds have not yet differentiated inside the tubers, so only leaves will grow but no flowers will bloom after planting.

Digging the bulbs too late can also cause the tuberose to only grow leaves but no flowers. The temperature is too low in winter, and the tubers are exposed to cold and freezing in the soil, causing the flower buds inside the tubers to be frozen and may even rot. This situation can also cause the tuberose to only grow leaves but no flowers.

Improper storage of bulbs during winter

Improper storage of tubers in winter, placing the bulbs in a dry cellar after drying, or burying them tightly with straw and soil will also result in fewer flowers.

Overfertilization

Applying too much nitrogen fertilizer after planting will cause the stems and leaves of tuberose to grow too long. This situation will cause tuberose to bloom less frequently, or even not bloom at all in severe cases.

What to do if tuberose only grows leaves but does not bloom

Choose good varieties

When choosing tuberose, you should choose those with larger and healthier tubers for planting.

Proper storage in winter

When storing tubers in winter, the room temperature should be maintained at 25℃-26℃. The moisture in the tubers will be gradually reduced until the outer skin becomes dry and wrinkled. Then the temperature should be lowered by 15℃-20℃ until they are taken out of the cellar in the next spring.

To store tubers in winter, you can also choose to hang the tubers indoors and place them under the stove for smoking. Baking can make the tubers drier, thus forcing the tubers of tuberose to enter a dormant period, which is beneficial for growth and differentiation of flower buds after planting in the spring of the following year.

Reasonable fertilization

Apply less fertilizer in the early stage of planting. Wait until the flower stems are about to emerge or before flowering, then apply fertilizer and also apply top dressing.

Generally, apply it once one month after planting, once before flowering, and then once every one and a half months or two months.
