Preventing root rot is simple. It's all about watering and drainage. Follow these simple rules and you will never see root rot in your plants. Give your plant proper drainage - Make sure your plant is potted in something with drainage hole(s), either a plastic nursery pot or a decorative pot that has a drainage hole.
Allow for Good Soil Drainage
For container plants, potting soil should be used and pots must have drainage holes. Any saucers below houseplants should be emptied regularly and plants need to be potted in appropriately sized, not oversized, containers to avoid an excess of moisture in the soil.
It can be quite normal for plants to temporarily stop growing after repotting, especially if you went up a lot bigger in pot size. What you want to try to avoid is transplant stress, such as yellowing, wilting, dropping leaves, roots that don't recover, root rot or even plant death.
All containers used for planting must have holes in the bottom to prevent water from sitting in the pot. Avoid using drainage materials at the base of the pot like rocks or gravel as this will actually hinder water movement. Use high quality potting soil and compost soil in the pots or containers used.
Remove about one-third or more of the old potting mix surrounding the plant's roots. As it grew, your plant removed some or all of the nutrients in the current mix, so you'll want to give it fresh potting mix or soil. Pour a layer of fresh potting soil into the empty planter and pack it down, removing any air pockets.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
Yes, coffee grounds can help prevent soil diseases… in a laboratory. Mixed into a growing mix, they have been found to control such harmful fungi as Pythium (which causes root rot) and Fusarium and Sclerotinia (vascular diseases).
Rocks in the bottom of containers do not contribute to better draining soils and healthier plants. Instead plant roots encounter saturated soils that don't drain efficiently. It all has to do with something called a perched water table.
Coffee filters hold moisture: Since coffee filters are absorbent, they will retain some moisture from each watering. While it's not enough moisture to cause root rot, it may give you a bit of extra time between waterings or tide you over in case you (gasp) miss a watering session.
Another product that'll help prevent the spread of root rot is non-flavoured cinnamon. After having removed the dead roots, sprinkle a thin layer onto the healthy tissue before placing into a bed of new compost.
Water thoroughly after repotting to help the soil settle around your plant's roots. Plenty of moisture will also help your plant recover from the move better. If you have a saucer under the pot, make sure to empty it, so your plant doesn't get too soggy.
Loosening the root ball when repotting is only essential when the plant has become completely root bound. In cases where they are not completely rootbound, you may be able to plant directly into the next pot. If the roots are not wrapped tightly around each other, there is no need to cut and disturb them.
If your plant succumbs to root rot, you can reuse the soil in a new plant, however, you'll have to take a few important steps first, such as sanitizing it (which we describe below).
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start. What does root rot look like?
Sand. Sand is one of the main properties of any type of soil. The grains do not retain or hold onto water, so they are perfect for use in the bottom of indoor planters to aid in drainage. Sand often used by professional growers and is usually mixed in within greenhouse and nursery growing mixes.
If there are concerns about compost finding their way down to the drainage holes and potentially blocking them, then the likes of newspaper, fabric, paper, or even coffee filters can be used to line the base of the planter and give a protective cover to the holes.
You know that last bit of coffee that always seems to be left in the carafe? Don't just pour it down the drain — you can use it to fertilize your plants, both indoor and outdoor. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems.
In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass.
It also breaks down into the soil and releases extra oxygen that helps the plant grow new, healthy roots. Before you use hydrogen peroxide on your plants, you'll need to dilute it. Mix one part of 3 percent hydrogen peroxide with two parts water in a watering can or spray bottle.
Baking soda has a pH of around nine, and its alkalinity will act as poison for fungi. It will eliminate it from the roots by alkalizing the soil and preventing it from developing.
