Why Overwatering Is Harmful 

It is easy to overwater a plant like broccoli that requires a lot of moisture to thrive. But too much water can negatively impact the vegetable. If the soil is too wet, the roots cannot properly absorb oxygen. Additionally, the plant will be susceptible to fungus infections. Your broccoli will soon die. 

To avoid overwatering, only water your broccoli plants when the top 2 inches of soil feel dry to the touch.

Signs and Symptoms

1. Downy Mildew

Downy mildew, a frequent problem with broccoli, is brought on by the fungus peronospora parasitica and is made worse by a humid environment. On the bottom surface of the leaves, downy mildew may be seen as a gray mold, while the top leaves often show indications of yellowing before turning brown and withering. When the plant is harvested, the darker florets indicate internal injury.

2. Yellowing Leaves

When a broccoli plant receives an excessive amount of water, the roots are unable to adequately breathe since the oxygen supply is restricted. This results in the leaves turning yellow.

3. Root Rot

When soil is allowed to get saturated with moisture, it becomes more difficult for air to move through the soil and reach the roots of the plant. The lack of oxygen will lead to root rot, which, in turn, will cause the plant to die.

4. Wilting Leaves

Wilting occurs when water starts to fill the air gaps in the soil, which ultimately leads to the roots starting to die. Wilting leaves are the first sign that the plant receives too much water and not enough air.

How to Fix It

1. Stop Watering and Allow Time to Pass

The most obvious way to avoid overwatering is to provide less water and wait longer between watering sessions. The plant will utilize the water that is already present in the soil, giving it a chance to dry out and allow air circulation to start up again. 

2. Remove Mulch from the Top of the Soil

Mulch helps to keep the soil’s moisture content stable. It is imperative that you remove the mulch from the top layer of the ground to quickly dry the overwatered soil. The water that isn’t necessary will evaporate considerably faster once you remove the mulch.

3. Place Plants in a Windy Area

If you have overwatered your plants, you need a way to help the soil dry out quickly. The wind speeds up the evaporation process. If you place your plants in a windy spot, it will help them recover more quickly. The quantity of water lost by the plant will increase with the strength of the wind.
