Hi i planted 6 red cordylins 2 years ago i purchased from a nursery. .in a new planter box i made they were thriving in the soil grew double in hight
I took them out layed weed mat riverstone pebbles and new hedge infront of them
I replanted in the same location they where in before
added new batch of garden mix around the roots
watered them after and never rewatered them for two days after but noticed 3 out of them start to wilter and soon the other 2 started to lose color
they are now turning into a brown yellow color.
Started to turn the sprinkler on for 3 days inna row for 2hours thinkn needed water not the case
Neighbor suggested thriving elements to solve the problem

Need a bit of clarification please. You say you put all six plants in a planter box 2 years ago, and they grew well - how wide and deep is the planter box?
When you took them out of the planter box, did you put them back in the box, or in the ground? When you took them out, did you then replant them separately in the ground, spaced out more (I'm assuming the roots of 6 plants were pretty much entangled up together)?
IF you had to pull them apart at the root, and IF you replanted into the ground, they would have needed excessive amounts of water for the first two weeks to a month - when you break plants apart, you destroy the fine, water seeking roots, and so the plant can't take up enough moisture - it would have been essential to keep the plants well supplied with water until those roots had recovered.
I do not understand the term 'thriving elements'... but if your friend means feeding with certain elements to help the plants, don't waste your money or time on that - the problem is the plants can't take anything up because they've lost root material. Keeping them well watered from now on MIGHT mean they don't die and regrow, even if its from the bottom of the current stems, at the base of the plant.
