One of the worst things that can happen to plants is root rot because it can cause all sorts of problems at least once it has started.
Unfortunately, nopal is also susceptible to root rot if cultivation has not been optimal.
Fortunately, it’s fairly easy to determine what causes root rot and what the signs are, so you can quickly save your cactus from further damage and get back on track.
So, without further ado, here’s everything you need to know to identify root rot on a prickly pear and then save the cactus, too.
Causes of root rot
The main causes of root rot in a cactus are overwatering and/or poor soil drainage.
These go hand in hand, as too much water will make your cactus’s feet soggy and even if you water sparingly, if the soil can’t drain properly, the cactus will remain too wet anyway.
So, for prickly pear, you will need to water on average once every few weeks, but only when the soil is completely dry.
Watering only when the soil is dry not only prevents overwatering and root rot, it also makes it much easier to know when to water because you can smell the soil and then decide whether it’s time to water or not. .
Also, be sure to use soil made for cacti so that there is good drainage as well.
Signs of root rot.
Some of the most common signs of cactus root rot are yellowing then blackening, stunting, sagging or wilting, or general crumbling of the cactus.
Typically, when root rot begins to set in, you’ll first see the prickly pear sag or become stunted.
You can then see the plant begin to turn yellow and eventually black as the process progresses.
You may even notice a foul odor emanating from the underside of your prickly pear, the roots rotting, hence the term root rot.
Normal healthy nopal roots are firm and white, and unhealthy rotten roots are soft and black.
So if you have any of the above symptoms it’s time to check the roots and if they aren’t firm and white you have rotten roots and you need to work fast to save your cactus.
