How to water a Chaenomeles speciosa (flowering quince) bonsai? Master these tips for vigorous growth
Chaenomeles speciosa is drought-tolerant and, although it fears waterlogging, it still quite likes a humid environment, so you must not water it sparingly or skip watering just because it fears waterlogging.

Chaenomeles speciosa is fairly drought-tolerant, and during the growing season it is generally watered thoroughly once the soil has dried out. In summer, spraying and watering should avoid midday. Although Chaenomeles speciosa fears waterlogging, it still quite likes a humid environment, so you must not water it sparingly or skip watering just because it fears waterlogging, because a lack of water will also affect its normal growth: in mild cases the leaves become small, drop or wilt, and in severe cases the whole plant dies. When watering, it is best to rinse the dust off the flower buds with water. So how should you water a Chaenomeles speciosa? You can draw on the following few points of experience.
During the growing season of Chaenomeles speciosa, give it plenty of water; especially when summer temperatures are high, the potting soil dries out easily, so watering must be ample. Note that Chaenomeles speciosa has a certain drought resistance but greatly fears waterlogging, so you must avoid water accumulating in the pot, otherwise the leaves will turn yellow and the plant may even die.
For Chaenomeles speciosa, simply keeping the potting soil moist is enough at ordinary times, but you must be careful to prevent water from accumulating in the pot, otherwise the roots rot easily. During the spring and summer growing season, the potting soil should not be overly dry either, and especially during the flowering period the potting soil must be kept adequately moist.
The annual winter-protection watering and the spring green-up watering are indispensable; these two waterings must be timely and moderate in amount. "Timely" means the winter-protection watering must be finished between mid-November and before early December, and the green-up watering must be given in early March. "Moderate in amount" means it must be watered sufficiently and thoroughly.
In addition, it is also very necessary to give one thorough watering in mid-April after flowering, which is what the farming proverb calls "water after flowering is better than ginseng soup." At other times, the number and amount of waterings should be determined by the soil moisture. Generally speaking, in the rainy summer season watering should be controlled, and if there is too much rain you should also pay attention to drainage to prevent excessive water from rotting the roots; but in hot, dry periods, timely replenishment of water is necessary. Another point to note is that after autumn begins you should control watering to prevent autumn growth, so that the new shoots do not suffer freeze damage when overwintering.
