How to Plant Irises? A Detailed Guide to the Latest Planting Methods

Iris, also known as blue butterfly, is a perennial flowering plant and a flower native to China. It is a common groundcover flower in garden landscaping. There are some points that require special attention when planting irises. In addition, planting should be based on growth characteristics to determine the specific planting method. In fact, every kind of flower is planted differently, and it is precisely because these differences exist that we will now take a look at the specific details.

1. Soil

Soil requirements are actually not strict; generally, most soils can be used for planting, since most soils are yellow loam, red loam, or black loam. Saline-alkali and desert soils are also rare. You just need to improve the soil yourself when planting, for example by adding humus soil, peat, sand, or fermented materials. In this way, the soil can reach the standard you want.

2. Temperature

Growing temperature is divided into soil temperature and ambient temperature. Generally, the minimum soil temperature is required to be above 8 degrees, and the maximum temperature below 20 degrees. The best temperature is between 15 degrees and 18 degrees. The ambient temperature is 15 degrees to 20 degrees. If grown in a greenhouse, the temperature can be lower, for example around 13 degrees, but not lower than 10 degrees. However, when grown in the open field, it can still grow well at 23 degrees during the day

3. Water

Iris likes a cool and moist environment, so the moisture content requirement is relatively high, generally around 70% humidity. However, water must not accumulate, and it cannot be planted in low-lying land, which is not conducive to drainage. After heavy rain, be sure to pay attention to timely drainage. Generally there will not be drought, as the dry season has already passed the flowering period. But the plants should still be watered appropriately. Generally, open-field planting should be done under trees, so it is less likely to dry out and is relatively moist.

4. Fertilizing

Generally, if fertile soil is chosen, no fertilizer is needed; it can grow naturally and still grow very well. Therefore, there is no need to fertilize before planting, as fertilizing hinders root growth. During the growing period, if yellow leaves or poor flowering are found, indicating insufficient growth nutrients, then appropriate fertilization can be applied. Fertilization mainly uses nitrogen and potassium fertilizer, and phosphate fertilizer must not be applied.

Planting irises only requires attention to adjusting the planting environment, and this is also the specific planting method. Finally, there is the planting situation; sometimes it is necessary to discover problems according to real-time conditions and adjust at any time.
