III. Flower Management

1. watering

As the temperature continues to rise, potted ornamental plants will gradually increase the demand for water, in addition to the need to pay attention to the combination of root watering and foliar spraying, but also must pay attention to the quality of irrigation, spraying water, it is best not to directly use tap water, especially not to directly use tap water treated by bleaching powder. To this end, tap water can be poured into the pool or small tank first, and then add an appropriate amount of acidifying substances to improve the acidity of the water quality, such as ferrous sulfate, the concentration can be controlled between 0.1% and 0.2%.

Potted flowers after pruning, to moderate drop 10 to 20 cm, located in the middle of the bud can be pregnant flower buds.

(2)Bud picking For the bud picking of potted wintersweet plants, attention should also be paid to the position of bud picking, generally 3 to 5 cm above the selected leaf bud position, otherwise it will also dry up due to wound atrophy, affecting the selected leaf bud downward. For those on the pot in that year, the terminal buds should be picked in time to promote the formation of good plant shape.

3. shading

After entering May, it is advisable to move potted plants that like semi-shade or shade to shade or shade, such as: turtle back bamboo, palm bamboo, arrowroot, spring feather, green giant, red (green) gemstone, green emperor, pink leaves, caltrop, fruit arrowroot, orchid, Stangipani, camellia, tea plum, etc.; for light-loving flowers and trees, sufficient light must be given, such as wax plum, iron tree, fire thorn, jasmine, white peony, etc.; Bonsai plants, such as elm, finch plum, triangle maple, water bayberry, oak wood, June snow, black pine, cotton pine, etc., are required to have sufficient light; and, tiger thorn, red nan, cuibai, five-needle pine, etc. can be appropriately shaded.
