How to Save Your Gardens from Rotting Iris Roots Bulbs

Have you ever planted irises in your garden and noticed the leaves turning yellow, the flowers wilting, or even worse, the entire plant dying? The culprit could be rotting iris roots bulbs. Rotting of the iris plant is a common issue faced by gardeners and can lead to a significant loss. In this article, we will discuss what causes rotting iris roots bulbs and how you can save your gardens from this problem.

What Are Iris Roots Bulbs?

Iris roots bulbs are underground storage structures that contain all the essential nutrients required for the growth of an iris plant. These bulbs store energy produced by the plant through photosynthesis, which is later used during the dormant period to help the plant survive harsh weather conditions.

What Causes Rotting Iris Roots Bulbs?

The most common cause of rotting iris roots bulbs is overwatering. When the soil remains wet for an extended period, it creates an ideal environment for fungal growth, leading to root rot. Overcrowding of bulbs in a small area can also lead to rotting as they compete for limited resources.

Another reason for rotting iris roots bulbs is poor drainage. If the soil doesn't drain properly, water accumulates around the roots, causing them to rot. Exposing the bulbs to direct sunlight can also cause them to dry out and become susceptible to rot.

How to Save Your Gardens from Rotting Iris Roots Bulbs

1. Proper Irrigation

The first step to saving your garden from rotting iris roots bulbs is proper irrigation. Water your plants only when the top inch of soil is dry. Avoid overhead watering and prefer drip irrigation to prevent waterlogging in the soil.

2. Good Drainage

Ensure your garden has good drainage by adding compost or organic matter to improve soil structure. You can also create raised beds to provide better drainage.

3. Adequate Spacing

Plant the bulbs at least 12 inches apart to avoid overcrowding, which can lead to competition for nutrients and moisture.

4. Fertilization

Fertilize your garden with a balanced fertilizer to provide your iris plants with essential nutrients required for their growth.

5. Sun Exposure

Provide your plants with partial sun exposure, especially during the hottest part of the day. This helps prevent the bulbs from drying out and becoming susceptible to rot.
