I recently planted a leucospermum. Now some of the leaves are turning yellow on the bottom third of the bush. What would cause this? I have it in a 1/2 wines cask outdoors(bottom knocked out). I've had it on a drip watering system that waters it every 2nd day for 30 minutes. I've now cut the watering back to every 3rd day for 15 minutes. Is this still too much?
Drainage is very important, so you will need to check the soil instead of watering on a schedule.
Yellowing leaves can indicate watering issues, pest and disease.

The plants are about 2 1/2 years old and doing very well. We have two of them on a hillside and they need to be contained.
Pruning consist of deadheading, mainly. In order to control the spread, you will need to cut and dig out sections. In order to retain this, permanently, you can sink a garden border deep into the ground in the area that you want the plant to remain.
Here are some articles that will offer more information:

Can my leucospermum be pruned right back? Appears to be dying after severe long term rain. How can I revive it?
Trimming will be, only, part of correction. You will need a fungicide to correct the issue, though.

It is my first time and want to success raise Leucospermum Hybrid (Pincushion Carnival Red) from Lowe’s in San Diego, CA. My understanding the plant is sensitive with certain soil to use. What I plan to transplant the plant in a ceramic pot. Garden worker recommended me to use the soil (see photos). I’m not too sure. I want to double check by you if the soil is ok or not. If not, what would you recommend the soil? Thank you for read this. (Not sure if photos will show up) it is Miracle Grow Performance Organics for all purpose container mix.)
No, that mix will not be suitable. The soil needs to contain little to no nutrients, and be quite acidic. Peat moss mixes work fine, amended with pine bark and other materials to make it acidic.
