How to save a bottle palm with root rot? A few effective remedies

The bottle palm (Beaucarnea recurvata) is a very unusual plant: its leaves and stem are slender and elongated, but its base is very large and swollen, just like a wine bottle. The bottle palm has fairly wide uses; it can be grown as a small potted plant in a flowerpot, and can also be grown in medium or large pots as a decorative potted plant for halls, meeting rooms, shopping malls and other places. Bottle palms sometimes develop root rot, so why does a bottle palm that has been growing well suddenly get root rot? Below, Qinong Web will explain, based on the causes of root rot, how to save a bottle palm with root rot.

In fact, when a bottle palm develops root rot, in most cases it is caused by inadequate care methods; root rot truly caused by problems with the plant itself is relatively rare. Here, Qinong Web mainly summarizes three causes, and you can compare them with your own growing methods.

1. Excessive fertilizing

With such a large base, it is easy to see that this plant uses it to store nutrients and water. So fertilizing it is a bit different from most plants: if too much fertilizer is applied, it cannot absorb that much, so it accumulates in the soil, and if the concentration is too high it may poison the plant's roots and cause root problems. When the roots have problems, fertilizer should be stopped; once the roots have problems, their absorption capacity itself drops a great deal, and applying more fertilizer and water at this point is undoubtedly adding insult to injury for the plant.

2. Overwatering

Some plants get root rot because of overwatering, which creates waterlogged soil and leads to root rot, and the bottle palm is no exception. This plant itself is a very drought-tolerant plant, so excess water is completely harmful and not beneficial to it; long periods of high moisture erode the plant's roots, and the root base is very prone to rotting. So watering should normally be controlled, and be careful never to let the soil in the pot become waterlogged. On rainy days, it must absolutely not be left out in the rain, also to prevent waterlogging; if it does get rained on and the excess moisture is not removed in time, after a period the plant's root base will definitely begin to turn black and rot.

3. Root rot caused by pests and diseases

When the roots have problems, it may be that the plant is sick. There is a type of bacterium that erodes its root base, causing the roots to turn black and rot, so we should detect it in time and treat it early. In the early stage of the disease, dilute agricultural streptomycin at 1:1000 and spray it on the affected parts of the plant, or drench with 65% dexon diluted at 1:800, which has a very good effect.

4. Treatment methods after root rot

After discovering root rot on a bottle palm, first pull the root base out of the soil and observe the extent of the rot; if the root rot is not severe, it can still be saved. At this point, cut off the rotted parts; you can cut away a bit more to prevent any rotten roots from remaining, then wash the whole root base clean and put it in a cool, shaded place to dry for five or six days. Then you can soak it in rooting hormone and replant it in the pot.

The above is what Qinong Web has introduced here on the topic of “how to save a bottle palm with root rot.” The bottle palm is originally a tropical foliage plant, but it is fairly cold-tolerant; in southern regions it can be grown in the open ground, and it can overwinter safely as long as temperatures stay above 0°C, while in northern regions it should be grown in pots so it is easy to move indoors.
