Perhaps your chestnut begins to flower due to the fact that he was a little place. Chestnuts do not tolerate overcrowding. When planting, try to select one plant circumference, a component of diameter at least three meters. This will give the chestnut a space for proper growth and development. In close planting the plants begin to compete with each other, fight for territory, so are not in bloom. Experts say that after a while a few plants will perish under the onslaught of the neighbors, and the rest will continue to gain momentum, and only after that they will start to bloom.
Another reason for the lack of flowering may be a lack of heat. It all depends on the grade of your chestnut. For example, horse chestnut can delight you with their blooms even under conditions of a cool spring, but if your site is edible chestnut, they need a minimum temperature of 15 -18 ° C, otherwise they will not bloom. Plus chestnut that it is enough just a couple of warm days so that he could build up the color.
If chestnut is young and does not want to start flowering, so the plant just has not yet formed. You should wait. The minimum age for flowering horse chestnut - 10 years, and for other types this figure can be more, and an average of 15 seasons. If you believe that your chestnut is already reached the required age, you need to look for another cause for the lack of flowering. Maybe it's the lack of moisture. Chestnut loves water. Sometimes candle buds appear on the plant, but never disclosed. This may indicate dry air and soil.

The fact that the apartments castanospermum not bloom at all, except in some unique cases, so if you are the owner of this variety of chestnut, do not try to get him to blossom at home.
