If you water it, you can't choose the time around noon or two o'clock. At this time, the sun is very strong and it's not suitable for watering. The time suitable for watering is in the early morning, when the sun just appears, or in the evening when the sun is about to set.
Water the iris, observe the soil layer in advance, wait until the soil surface is dry, then give water, at this time, it is more appropriate to give water. After determining the water demand, first take out the water, and then dry it for a period of time. When the water quality is appropriate, the water can be slowly supplied from the side, not directly from the plant.
After sowing, there is a large demand for water, so more water can be given to keep the soil moist. At the later stage of growth, the growth almost stagnated and the demand for water decreased. In the general growth stage, keep a moderate amount of water, and then pour it until the flowerpot bottom flows out.
The frequency of water application should be determined according to the growth stage. In the two periods of late spring and early summer, the frequency of water application should be higher, and the secondary water can be given in 3-5 days. From the end of autumn to winter, the growth is almost stagnant. During this period, it can be done without watering or once a half month.
