A detailed guide to iris planting methods and cultivation techniques

Iris, also called blue butterfly, is a perennial flowering plant and a flower native to China. It is a common groundcover flower in landscaping. There are some points to pay special attention to when planting iris. Also, you should plant according to its growth characteristics to decide the specific planting method. In fact, every flower is planted differently, and it is precisely because of these differences that we will now look at the specific details.

1. Soil

The soil requirements are actually not strict; it can generally be planted even in very hot conditions, 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. That 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 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 below 10 degrees. However, when grown in the open field, it can also 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. But it must not become waterlogged, and it naturally cannot be planted in low-lying land, which is not good for drainage. After heavy rain, you must pay attention to timely drainage. It generally will not suffer drought, and the dry season has already passed the flowering period. But the plant should be watered appropriately. Generally, in the open field it should be planted under trees, so it is less likely to dry out and is relatively moist.

4. Fertilizing

Generally, if you choose fertile soil, you do not need to fertilize; growing naturally this way, it can still grow very well. So there is no need to fertilize before planting, and fertilizing hinders root growth. During the growing period, if you find yellow leaves, poor flowering, or insufficient growth nutrients, then you can fertilize appropriately. Fertilizing mainly uses nitrogen and potassium fertilizer, and phosphorus fertilizer must not be applied.

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