How to fertilize Amethyst Cactus
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 Amethyst Cactus after it doubles in size or once a year—whichever comes first.

Is it okay to hold the catcus to drain it out by the pricks? #MelonCactus

#happyplants I can't seem to shake whatever this thing is. It only crawls. I cannot tell the difference between Thrips, gnat babies, or the helpful ones whose name I can't remember. Can any of y'all assist? Note that I have put it through a host of cleanings over the last months.

Take a look at my babies🥰 Pulled out my tiny microscope today to get some close-ups on the new-borns. They started sprouting about 4 weeks ago. They are smaller than a needle pin head, and are just starting to get their first spines 🤗 #cactusclique #seedlings #newgrowth #whatthesuccwednesday #happyplants #plantsmakepeoplehappy #plantaddict #underthelens

Cacti cultivating! I have just started reading about the Melocactus Bahiensis, from which I have gathered and sowed seeds from last week.👀 Aaand I am hoping I am blessed with a lucky charm for difficult plants (as I had success with the first Calathea I got when I knew nothing).😅 Well. For anyone interested, some of my seeds have indeed started sprouting!👶👶 I am so excited 😄 And also so nervous as all I am reading now is that this cacti is for experienced cacti cultivators. And I have never done this before😂 So wish me luck! And any advice is gratefully received😄🌵 Sorry for bad photo, but I don't want to open the zip-bag they are in😅 If you know they are there you might see one or two green dots (there are 6)🙈💚💚 #cactusclique #cactus #melocactus #cultivatedflax #whatthesuccwednesday #succulentsquad #succulentlove #newgrowth #happyplants #adhdplantlovers

What is this white thing?? Help? What is it? I am very concerned...is it a fungus?! #SucculentSquad #Succulents #Succulent #CactusClique #Cactus #Cacti

Is this a good decision? #ChaoticPlainsUpdates I’m getting a new pot for Pyrite the pot is going to be terracotta because he struggles with the soil being wet for too long. Will that fox the issue? I don’t want him to rot. I’ve been sparing with watering so he’s been fine, but He gets squishy every now and then and it takes him a while to recover. Is this the right decision? #CactusClique #Cactus #Cacti #SucculentSquad #Succulents #Succulent

Why is the soil draining so fast? ☘️WARNING THIS IS LONG☘️ So about a month ago is switched Pyrite <0.5m away from a window (See the picture). Here’s the thing…his soil has been draining in 2-3 days and he’s been kinda pale. The window gets LOTS of sun and LOTS of heat. So could it be the change in scenery? There’s rocks in the soil so I’m surprised it’s draining so fast. I think the paleness is just too much sun (I forgot to rotate him), but I’m worried it might be something else (bc the soil drains so quickly). Is it possible the soil is hydrophobic?? If so what do i do? #SucculentSquad #CactusClique #Cactus #Cacti #Ferocactus

Well, this happened… 🪴 #ChaoticPlainsUpdates !! Story time yayyy!! 🌱I almost killed my #Ferocactus ! 🌿 STORY TIME!! Pyrite was very, very, pale and I gave him more sun to see if that would fix it. It didn’t, things only got worse. I checked to see the last time I watered him…the 28th of July…it’s AUGUST 8th!!! It explained SO MUCH! I gave him a cup of water. 🪴Now, hopefully, he’ll be ok! If anyone can give me tips on how to avoid this, that’d be great! #SucculentSquad #CactusClique #Cactus

Why does the soil dry so fast? I watered Pyrite a few days ago (Thursday specifically) and the soil is already almost completely dry. Is something wrong? #SucculentSquad #CactusClique
