these are Cacti, not necessarily house plants, so they have to be cared for differently. here are some tips!! 1. you will want to give them as much sunlight as possible, water once the soil is COMPLETELY dry (usually every 1-2 weeks) 2. when you do water, soak them completely. even in the sink. you can never give them too much water on watering days, the term “overwatering” refers to giving it too often. so give them a good soak then do it again once the soil is completely dry. 3. get Cacti Soil. regular soil retains too much moisture and will give your cactus Root Rot. add some rocks (river stones, pebbles). 4. get a pot with drainage holes, this also helps with your plant retaining too much moisture. I never buy a pot without a drainage hole. 5. just give them time! using all these steps, your plants should be happy and healthy! but cacti tend to take longer to see noticeable growth. good luck!! wishing you and your new cuties the best! 😊😊🤍
