I recently discovered that my cactus has been under-watered!! So I started watering it by thoroughly saturating the soil by leaving it in a bucket of water for about an 1.5 hours when the soil was dry (have done it twice now most recently 2 days ago and 8 days after its last bath the soil was completely dry). I let it sit until the soil feels moist on top. It takes about 6 days for most of the soil to dry out then another 2 to get completely dry again. Well the results are great except only one cactus seems to be benefiting....pictures of this are the two cactus that are side by side, one picture if from sometime in July, the second August 9th the day of their first real bath, and second is from today.
Second question is I have a Cereus Peruvian Apple cactus that just looks plain ole weird. It was also growing a baby and was under-watered so it got too spindly and flopped over so I cut it off and a new baby started growing from that cut (the cactus cutting is doing fine btw). It grew exponentially. First picture of it is from the first week of July, second from August 14th, then the last two from today. Lately it has stopped looking so swollen and the skin looks almost wrinkly and it seems to be leaving. I started watering this cactus properly the same time as the other cacti. I don't know if I should just let it keep doing it's thing or if I'm risking it flopping over like the other baby. Am I doing something wrong? I recently got a cactus fertilizer should I fertilize them? Thanks in advance!
