How to fertilize Cactaceae

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Cactaceae after it doubles in size or once a year—whichever comes first.

How do I repot a new cactus? Or should I even repot them? I have 4 cacti, all different but their care methods are very similar. They aren’t big at all and their pots are no bigger than 4 inches in diameter. They are all still in their nursing pots(plastic but inside a frosted glass pots). Greg said I should put them in terracotta pots, I’m down to do it but idk how or if I should just wait? Help #NewPlantMom #pleasehelp #idkwhatimdoing

I’m pretty sure he’s just burnt but I’m double checking lol Ok so I have this cactus and I put him in my west facing window with a lot of different plants and all of the different plants are fine and dandy but for some reason the cactus is the crispy one. All of the other plants are leafy and green but the literal desert plant is the one who got burnt lol. Or maybe he’s not burnt and it’s something else but I doubt it. The picture doesn’t show all of the crispiness but you can see a little bit of it on the tips of the plant. I’m just gonna give him some water and keep him a little further away from the window, hopefully that solves it!

Cactaceae is generally easy to care for, though some plant parents report facing challenges with growing it. Check out the reviews down below to read more about their experiences!
💦 Water Needs
Cactaceae thrives in dry soil and should be watered sparingly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
☀️ Sunlight Needs
Cactaceae requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
🐶 🐈 👶 Toxicity
Cactaceae is not known to cause harm to humans or pets. Regardless, if you, a family member, a cat, or dog has ingested any plant material, please consult a doctor or a veterinarian.

💨 Humidity
Cactaceae 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.
🪴 Soil
Cactaceae is very sensitive to wet soil, so choose a potting soil that drains very well and doesn’t 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!
💩 Fertilizer
Cactaceae grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
❄️ Dormancy
It’s common for Cactaceae to go dormant in the wintertime and you may notice their growth slow down. Waterings should be spaced out more during this time.
🌎 Native Region
Cactaceae is native to the Southwestern United States, Central America, and the Caribbean.
🌸 Flowers
Cactaceae produces flowers in the wild, but does not flower when kept as houseplants.
⬆️ ⬇️ Growth Pattern
Cactaceae grows vertically and new growth will emerge from the top of the plant.
🌦️ Growing Outdoors
USDA Hardiness Zone
Cactaceae can be grown outdoors in USDA Hardiness Zones 10-12b. Find your local hardiness zone here.
🌱 Propagation
Cactaceae can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
🧐 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.
😖 Common Issues
Overwatering is a likely cause of issues with Cactaceae. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.
Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!
