I was a little nervous about my cactus because it has some brown on the bottom. I wasn't sure if it was age, too much water, bigger issue, etc. I have been watering according to Greg and it's been doing great otherwise so I decided to deep dive into questions other #greggers have had. After reading other posts I decided to use a wooden stick as @kscape recommends to make sure I was actually water properly. I couldn't get it in the pot š¤¦š½ So today it got an upgrade. I knew it had been a while, but since it was growing well I was trying to just let it be. The soil was a rock, I have no idea how it held any water. After a lot of debate if I should move it up a pot size I decided to pull the trigger. After a good #buttchug it's back in it's sunny spot and, hopefully, much happier š¤š¼ #cactusclique #cacti #cactus #happyplants #plantsmakepeoplehappy #repotseason š± #NewEnglandGregGang š± #MaineGang š± #ThePlantMompy

Unsolicited #PSA ! Just because a #cactus is densely spined, it is NOT immune to mealies! In moving this #mammillaria back to school and viewing it in more focused light, I noticed a small infestation that I had been missing. It is so easy to spot #mealybugs on gymnos and echinopsis, but I tend to take these mams for granted when doing #pest checks. Don't neglect the nips! #cactusclique #succulentsquad #plantsmakepeoplehappy #plantaddict #happyplants #deathtomealies

āļø Sunlight Needs
Mammillaria Compressa requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive šŖ. Select your region to see how the current weather in your area affects the placement in your home š”.
š¶ š š¶ Toxicity
Greg does not have confirmed data on this plantās toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, itās always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA atĀ US (888) 426-4435.
šØ Humidity
Mammillaria Compressa enjoys lots of humidity. Provide humidity for your plant by watering regularly and thoroughly, since plants absorb most water through their root system rather than their leaves. They may also benefit from being placed next to a humidifier.
šŖ“ Soil
Mammillaria Compressa is very sensitive to wet soil, so choose a potting soil that drains very well and doesnāt retain too much moisture. A good soil will have lots of perlite or vermiculite for drainage and some organic matter for nutrition. A few handfuls of perlite added to regular store-bought cactus soil will do the trick!
š© Fertilizer
Mammillaria Compressa grows very slowly and doesnāt require added fertilizer. Replacing your plantās potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
āļø Dormancy
Itās common for Mammillaria Compressa to go dormant in the wintertime and you may notice their growth slow down. Waterings should be spaced out more during this time.
š Native Region
Mammillaria Compressa is native to the Southwestern United States, Central America, and the Caribbean.
šø Flowers
Mammillaria Compressa produces flowers in the wild, but does not flower when kept as houseplants.
š§ Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
