Reasons and prevention methods of the failure of Euphorbia obliqua to bloom

Lack of light

If the flowerpot of Euphorbia obesa is placed in a shaded and closed place for a long time, the plant will lack light and produce fewer flowers. In this case, the Euphorbia obesa should be moved to a place with sufficient scattered light and good ventilation to eliminate harmful gases such as ethylene, which will cause the flower buds to age prematurely. However, care should also be taken to avoid excessive direct sunlight, otherwise the abnormal stems will turn yellow and burn, affecting flowering.

Overwatering

The watering of Euphorbia obesa should be moderate, and the soil should be kept dry and wet, but not waterlogged, otherwise the roots will easily rot. However, dryness is also not good for growth and flowering. The modified stems and the surrounding ground should be sprayed with clean water frequently to maintain a high air humidity.

Inappropriate fertilization

Excessive application of nitrogen fertilizer will cause the abnormal stems of the Euphorbia obesa to grow too long, which is not conducive to the differentiation of flower buds. Fertilization should be applied in appropriate amounts, and phosphorus and potassium fertilizers should be added once during the budding period to nurture flower buds and promote large and colorful flowers.

Inappropriate temperature

When the ambient temperature is too high, it will easily cause the abnormal stems of the Euphorbia lathyris to grow too long, affecting the symmetry of the plant shape. When the temperature is too low, it will hinder the bud formation of the Euphorbia lathyris. The temperature should be controlled between 15℃ and 25℃ during the growing period.

Unsuitable potting soil

When the pH value of the potting soil for growing Euphorbia obesa is too high, it will be unfavorable for the formation of flower buds. The heavy soil will cause root rot. You should pay attention to changing the pot and soil in time. You can use 4 parts of leaf mold, 4 parts of sandy soil, and 2 parts of fermented manure, mix them well and make the culture soil. You can put a small amount of hoof chips at the bottom of the pot as base fertilizer.

Too many flower buds

When there are too many flower buds on the Euphorbia obesa, it is not conducive to flowering. When the flower buds are too dense, it is easy to cause insufficient nutrient supply to the plant, resulting in the flower buds falling off in the later stage and poor flowering. Therefore, when there are too many flower buds on the Euphorbia obesa, you should pay attention to thinning the buds, removing the weak ones and keeping the strong ones, removing the small ones and keeping the large ones. In this way, the flower buds can get more nutrients and bloom well.
