Hi Kyle,
I do not know what causes the yellowing of specifically madagascariensis, but I do know adding lots of compost and lava rock for drainage in my clay hillside soils has helped all my palms and plants put on deeper green hues/ solid growth. The areas of the side yard I have been slower to add compost and drainage rock, has slower growing plants with more tip burn/ nutritional issues etc.
I am a believer in developing the overall soil health, and dynamism to get the best looking plants which often means lots of leaf drop and litter that other folks might find less attractive etc.
Every year or two I will do a big order of compost and mulch to cover the front and back yard, but this year I swapped out the organic mulch for draining 3/4 lava rock. Hope it helps with opening up my clay soils, but it also looks great against the green fronds!
