Excess water due to rain in the orchard and garden, what do I do?

If you have an orchard or garden, you may have to deal with more or less frequently throughout the year the damage that excess water or flooding from rains can cause to plants .

The soil of orchards and gardens provides support, nutrients and water to the plants. If this soil is flooded or flooded, it will not be able to provide an optimal environment for the plants, horticultural or ornamental, to develop well.

The rains, especially if they are strong or repetitive in a short time, can cause damage to plants, especially in two areas:

  • The water carries the nutrients with it and causes the impoverishment of the land because it reduces fertility and can also modify the pH and can increase its acidity (this phenomenon is known as leaching ).
  • When rainwater remains stagnant for several days or weeks because the soil is not able to drain it, it can cause root suffocation and rotting of the roots of the plants in your garden or garden.

Apart from this, I recommend that you take advantage of the rains to capture water and that you can use it in the following weeks or months for irrigation. See this manual on rainwater harvesting and storage .

Consequences of excess water due to rainfall (or even excessive irrigation)

The leaves of the plants can turn brown, yellow or orange and fall off, and if left unchecked, it can lead to the death of the plant.

Another very common consequence of excess water accumulated in the soil is root suffocation. Plants obtain oxygen, in addition to through the leaves, through the roots, but if the space surrounding the roots of the plants is flooded with water, there is a lack of oxygen, causing the progressive weakening of the plant until its death .

If we see that the plants do not grow at a normal rate, that we can easily remove them from the ground and that the leaves turn yellowish and later even reddish, it is very likely that you are suffering from root suffocation due to excess water.

When there is a stagnation of water in the soil that affects the functioning of the roots, they will not be able to properly absorb the nutrients that the plant needs for two main reasons:

  • The roots cannot perform their functions properly due to rot that can cause a lack of oxygen and excess water.
  • The bioavailability of soil nutrients is reduced because the soil pH becomes more basic.

In case the plant does not have enough, the constant presence of humidity rapidly causes the proliferation of fungi that are harmful to the plant, very easily appearing very common diseases such as mildew , rust or powdery mildew that have a devastating impact on the already existing plant. yes it is weakened.

To do? Solutions for excess water from rains

greenhouse rain ºº The first measure we must take is prevention. Today we can easily consult and know if there are going to be heavy rains in the coming weeks and thus we are not caught by surprise.

ºº Ideally, within the design of your orchard or garden you include a slope for these cases, especially if the area where you live usually produces heavy rains at some time of year. So what we do in directing the water where it interests us and avoiding or reducing flood damage.

ºº Make sure the farmland is soft, spongy, well drained and well aerated.

ºº You can use biodegradable plastics to create covers that directly protect plants from rain, especially those that may be more susceptible. Using very few materials that you have at home you can make them, although they are basic like the one in the photo, they are useful.

ºº Some materials used for mulch are very absorbent and can be helpful, such as gravel and pine bark.

ºº You can also make some channels or ditches that pass through key points of your orchard or garden where you want the rainwater to flow. A line through which you can easily drain the water into a suitable area.

ºº The days in winter have few hours of light, frequently cloudy, and the sun can be our ally to help evaporate part of that accumulated water.

ºº The wind also helps us in this case because it increases the dehydration of the soil and therefore the elimination of accumulated water.

ºº Aeration is very important, if you have plastics or similar placed in the garden and the water has reached the plants, try to remove them to leave the crops exposed so that the light and the wind help eliminate water.
