Hi @SinewyPyrethrum at 1st glance I’d say root rot, but you have little ones growing, so are there any pest or gnats? Is it soft where the brown areas are? Could it just be dug in dirt?
Either way you need to take action.
Here some I picked, the browning in the middle of your cactus could be a sign of a few things, but it's most likely related to either environmental stress, rot, pests, or disease.
Here are the most common reasons why a cactus might turn brown in the middle:
Sunburn or sun stress: Though cacti are hardy and often associated with hot, sunny climates, they can still get sunburned, especially if they are abruptly moved from a shaded location to an area with intense, direct sunlight. Sunburn can manifest as brown patches, sometimes hardening and drying the tissue.
Watering issues: Both overwatering and underwatering can stress a cactus and cause discoloration or browning. Overwatering can lead to root rot, causing brown spots on leaves and eventually softening of the stem and browning from the base upwards. Underwatered cacti may show signs of dehydration like browning patches or wrinkled skin.
Pest infestation: Pests like mealybugs, aphids, and scale insects can feed on the cactus's sap, weakening the plant and causing brown or discolored patches. They can also leave behind openings in the flesh that make the plant vulnerable to infections.
Fungal or bacterial infections: Cacti can be susceptible to fungal or bacterial infections, particularly in humid conditions or with excess moisture around the base. These infections often start as small brown spots and can spread. Rot, a common and potentially devastating issue for cacti, can also be caused by various fungi and bacteria, leading to soft, mushy stems, discoloration, and foul odors.
Physical damage: Bruising, or damage from mishandling, animals, or insects, can also lead to browning.
What to do
Assess the texture and location of the brown area. If the area is firm and feels like bark, it might be corking, a natural hardening process at the base of the cactus that occurs with age. However, if it's soft or mushy, and potentially emits a foul odor, it's more likely rot, according to Varnish + Vine and Spike & Bloom.
Examine your care practices. Review your watering frequency and ensure the soil is drying out adequately between waterings. Use well-draining soil and a pot with drainage holes.
Inspect for pests. Carefully check the cactus for insects or webbing.
Adjust lighting conditions. If the cactus is in intense direct sunlight, consider moving it to a location with bright, indirect light or providing some shade, especially during the hottest part of the day.
If you suspect rot, act quickly. You may need to remove the affected parts using a clean, sharp knife and allow the cuts to callus before replanting in fresh, well-draining soil. You can also try treating with a fungicide.
Could just be corking. If it’s hard and not squishy it’s fine!
@Preciousplants1 i wouldn’t know much about her conditions before she was given to me. i have had her for a little over two weeks thinking she needed: terricota pot, well draining soil and some sunlight and fertilizer (incase of pests i have moved her away from my other plants) but i haven’t noticed any pests or any odors, she’s also firm and not squishy at all.
@SinewyPyrethrum so did you already repot it? those are all good things for Cati: Can you look at the whole bottom of the plant and see if the dirt is wet or dry?
I see the top soil is dry (that’s good) can you take a little water 💧 on a soft tooth brush and see if it’s just dirt. Or was it like that when you got it thank you Destiny for the tag 😊
