1. Maintenance methods

1. Temperature: The most suitable temperature is around 18 degrees, neither too high nor too low. Generally speaking, temperatures of 13 degrees or lower will prolong its growth period and make the flowers easily wither. Temperatures that are too high will also have adverse effects.

2. Light: Irises like light. It can tolerate some semi-shade, but too much shade will have a negative impact on its growth and flowering. Therefore, in order to meet its requirements, try to let it receive as much exposure as possible when the sunlight is not so strong. Under strong sunlight, shade is required.

If the bulbs cannot be planted immediately, they need to be stored in a low-temperature environment, generally around two degrees Celsius, and maintained at appropriate humidity. Wait until the right time to plant. After planting, temperature and humidity are also two very important aspects.

2. Weeding: If weeds appear after the plants are planted , then it is necessary to carry out cleaning work. Herbicides can only be used if the bulbs are deep enough, but cannot be used if the bulbs are buried very shallow. Also pay attention to the number of herbicides used each year, preferably no more than twice.
