What to Do If Flowers Won't Bloom? These Methods Will Help You Solve It

For people who love plants and flowers, it is quite a blow when their plants fail to bloom.

In fact, aside from the plant itself being too weak to have reached the conditions for blooming, the reasons that affect blooming also include these:Insufficient light, poor ventilation, unsuitable temperature, unsuitable soil pH, improper pruning, insufficient nutrients, too much nitrogen fertilizer, pests and diseases.

Plants and flowers have different growth habits, so the treatments are naturally different too. Here are the treatments for several common flowering plants that will not bloom, so you can find the one that matches your situation:

Kalanchoe

Flowering period: February to May

Move it to a place with sufficient light: Kalanchoe loves light. Insufficient or too weak light will affect blooming. You can rotate the pot so it receives light evenly.

Reduce watering appropriately: Too much water during the flowering period easily causes leggy growth and flower drop.

Pay attention to fertilizing: Kalanchoe loves fertilizer. During the growing season, you can apply nitrogen fertilizer to promote stem and leaf growth, and after flowering apply one more liquid fertilizer mainly of nitrogen to help it recover. At other times, except for stopping fertilization in summer, only compound fertilizer of nitrogen, phosphorus and potassium should be applied. When fertilizing, do not get fertilizer on the leaves.

Gardenia

Flowering period: March to July

Maintain sufficient light: Move the gardenia to a place with good light, but the light should not be too strong or too weak.

Apply more phosphorus and potassium fertilizer before the flowering period: Gardenia loves fertilizer. During the growing season, apply decomposed cake fertilizer as a top dressing, and before the flowering season apply phosphorus and potassium fertilizer. It is recommended to change the soil once every 1 to 2 years to maintain soil fertility.

Slightly acidic soil: Gardenia loves acidic soil. When watering normally, you can add ferrous sulfate to improve the soil, and you can also often apply 10% alum fertilizer water as a top dressing.

Rose

Flowering period: April to September

Maintain light: Rose loves light. It is recommended to place it on a south-facing balcony or grow it outdoors.

Reduce nitrogen fertilizer before the flowering period: During the growing season, you can appropriately supplement some cake fertilizer, alum fertilizer water, etc. Before the flowering period, reduce nitrogen fertilizer and supplement phosphorus and potassium fertilizer.

Prune in time: Roses bloom on new branches of the current year, so they need continuous pruning. Cut off some old branches to promote new buds. For large potted rose plants, pruning should be combined with repotting in early spring, cutting off all dead branches, diseased branches and crossing branches.

Generally, for vigorous branches of mature plants, cut off 1/2, and for weaker ones cut off 2/3, leaving 3-5 strong main branches. After the first flush of flowers fades in October, promptly cut off the spent flower stalks to promote rapid sprouting of new buds.

Jasmine

Flowering period: May to August

Keep the potting soil slightly acidic: Jasmine loves acidity. During the growing period, a 20% ferrous sulfate solution can be used to water it once every half month.

Light must be sufficient: A place with sufficient light is beneficial for the sprouting of flower buds.

Water thoroughly: Neither too dry nor too wet is good, but in summer it needs to be watered once in the morning and once in the evening, thoroughly. If there are consecutive rainy days, do not let the potted plant get rained on.

Nutrients must be sufficient during the flowering period: In summer, when it enters the full flowering period, apply a thin decomposed liquid fertilizer once every 3 to 5 days; during the bud formation and flowering period, apply an organic fertilizer liquid mainly of phosphorus once every 3 days, or spray 1 to 2 times with potassium dihydrogen phosphate.

Prune in time: After the flowers fade, prune in time. Leggy branches should be shortened promptly, and after pruning apply a heavy fertilizer once.

Hydrangea

Flowering period: June to August

Repot in early spring: It is recommended to repot in early spring. When changing the soil, add decomposed cake fertilizer as a base fertilizer, and supplement phosphorus and potassium fertilizer before the flowering period.

Prune appropriately: The best pruning time is during the flower bud differentiation period (mid-July to early August). Only 2 to 3 nodes of the aboveground part need to be kept, and the rest can all be cut off.

Pay attention to light: It should be placed in a place with good light but no direct sun exposure. Insufficient light easily affects flower bud differentiation, but light should not exceed 10 hours. When placed indoors, exposure to fluorescent light at night affects blooming.

The temperature during flower bud differentiation should be low: Flower bud differentiation requires a period of relatively low temperature, 5 to 10°C, for about a month and a half.

Bowl lotus

Flowering period: June to September

The container must not be too small: Generally, a flower pot with a diameter of 25 cm and a depth of 30 cm is best.

Maintain light: It is recommended to move it to a place with good light.

It is best to use soil: To grow bowl lotus, soil must be used. In summer, a piece of bean cake can be inserted as a top dressing. If the potting soil and lotus leaves are abnormal, pour out the pot water and continuously add clean water to relieve it.

Bougainvillea

Flowering period: September to December

In some regions it can basically bloom all year round

Maintain light: It loves strong light. Place it in a place with good light. In northern regions, it should be moved indoors for care when winter begins.

Control watering before the flowering period: Control the amount of watering before the flowering period arrives, and water appropriately only when the leaves are slightly wilted.

Increase phosphorus and potassium fertilizer during the flowering period: During the growing period, apply nitrogen fertilizer once every 7-10 days. Stop applying nitrogen fertilizer during the flowering period and increase phosphorus and potassium fertilizer.

Improper pruning: Too many and too dense branches will also affect nutrient distribution and cannot promote flower bud formation. During care, according to the shape of the plant, irregularly thin out overly dense and surplus branches.

Camellia

Flowering period: October to May

Full flowering period January to March

Pay attention to ventilation: Long-term placement indoors, poor ventilation, insufficient humidity, room temperature too high (above 20°C).

Do not apply nitrogen fertilizer before the flowering period: In January, a mixed nitrogen and phosphorus fertilizer can be applied 1 to 2 times. Do not apply nitrogen fertilizer before flowering, only phosphorus fertilizer.

Keep the potting soil moist: The potting soil should not be too wet or too dry; keeping it moist is enough.

Cyclamen

Flowering period: December to April

Always pay attention to temperature: The suitable growth temperature for cyclamen is 15 to 20°C. When the temperature is above 28°C, it enters dormancy or semi-dormancy. Above 35°C, the corm easily rots. Therefore, in summer be sure to pay attention to shading, cooling and ventilation.

Water sufficiently after repotting: If water is insufficient, cyclamen ends dormancy and resumes growth in September. At this time it should be repotted promptly, and after repotting water sufficiently.

Pause fertilization during the flowering period: Apply a thin liquid fertilizer containing phosphorus and potassium once every 10 days, and pause fertilization during the flowering period.

Do carefully cultivated flowers always fail to bloom? No need to worry too much. No one grows them well from the very beginning. Take it slowly, look for the reasons carefully, and believe that the day will eventually come when the flowers bloom!
