Some gardening problems are easy to spot and become apparent very quickly. If you visit the garden one morning and find that big bites are taken out of your tomatoes, then a groundhog had probably dropped by for a snack during the night. But plant disease is usually a drag that sneaks abreast of you, and, even after the signs of it appear, you actually need to know how to identify, treat and prevent root rot?
What Is Root Rot?
At the foremost basic level, the disease may be a plant disease, but the key’s in learning what factors cause this disease. The disease is often caused by waterlogged soil or various sorts of fungi.
Soil can become waterlogged for a variety of reasons, including poor drainage, continuous heavy rainfall, and overwatering.
Overwatering could also be the foremost disconcerting of all. you recognize that your plants need water, and you are feeling that you simply are being conscientious by supplying them thereupon water. But this is often a case of “too much of an honest thing.”
Even overwatering or a strangely rainy period, however, are often not enough, in themselves, to cause your soil to become waterlogged. Their great enabler is poor drainage. Water runs through a sandy sort of soil sort of a sieve; it’s rare for such soil to become waterlogged. But a clayey soil holds water for an extended time. So it’s usually the mixture of poor drainage and excessive moisture that creates the bottom waterlogged.
You may not consider plant roots as wanting to breathe, but roots do need oxygen. that’s why waterlogged soil may be a problem for them: They drown in it, rot, die, and become useless to the vegetation they support, eventually leading to the death of the plant if you fail to unravel the matter. Ironically, roots rotting from sitting in an excessive amount of water are unable to soak up water and transport it to the remainder of the plant, which wilts.
Sometimes, the explanation for plant disease isn’t as simple as waterlogged soil. The direct cause could also be a fungus, like Phytophthora. But, even as poor drainage enables excessive water to become a drag, so waterlogged soil is an enabler for Phytophthora. Fungi thrive under wet conditions; Phytophthora rarely becomes a problem in soil that drains well.
How to Identify plant disease
The reason that plant disease is so hard to detect during a timely manner is that it’s developing underground, out of sight. Despite the name, “root rot,” gardeners usually spot signs of the disease within the plant’s leaves, not its roots. Unfortunately, the damage was already done by then.
Yellowing leaves are often a symbol of plant disease, and therefore the leaves may drop off. Leaves can become crooked or smaller than usual (deformed). Once you are doing inspect the roots, you’ll find that they’re a special color than normal (darker, reddish-brown, etc.) and stink with rot. yet one more sign of plant disease is that, regardless of what proportion you water the plant, it always looks wilted.
How to Prevent or Treat plant disease
Preventing plant disease within the first place may be a lot easier than handling it after you’ve it. Providing your yard with good drainage and avoiding overwatering are the 2 best prevention tips.
It is difficult to understand what proportion water is just too much, in terms of an actual measurement. the simplest thanks to determine if a plant is watered properly is to dig down into the soil just outside its root zone (close enough to ascertain what’s happening there but not so close that you simply damage the roots). Most plants like better to have evenly moist soil throughout their root zones. So if you discover the soil dried out down there, then you’re not watering enough. But if you discover it soggy, then you’re overwatering.
Yard drainage can be improved in several ways, including by:
- Mixing amendments into the soil such as compost
- French drain installation
- Grow your plants in raised pots
If you fail with prevention and find yourself with plant disease, all might not be lost if the plant in question is little enough (for example, a perennial instead of an enormous tree or shrub) and if you’ve got caught the matter in time. Houseplants, which are notorious for plant disease, can often be saved because they’re growing in containers, supplying you with quick access to their roots. you’ll treat minor cases of plant disease by first exhumation the plant, washing the roots, and removing (with a sterilized cutting tool) the diseased parts.
In replanting it later, you’ll either return it to an equivalent spot after improving the bottom with compost alternatively transplant it to a far better spot. Either way, giving your plants friable soil to grow in may assist you to avoid the matter of plant disease within the future.
Preventing plant disease With Smart Plant Selection
Nor do you have to overlook the importance of smart plant selection. If you recognize you’ve got a soil that stays wetter than is right for many plants, grow plants meant to be in or around water and/or plants that tolerate poor drainage.
- Northern blue flag (Iris versicolor)
- Willows, such as pussy willow (Salix discolor) And avoid growing the plants that are most susceptible to root rot, including:
- Mountain laurel (Kalmia latifolia)
- Rhododendron spp.
- Andromeda (Pieris japonica)
- Yews (Taxus spp.)
- Heather (Calluna)
- Mediterranean plants such as English lavender (Lavandula angustifolia)
