How to tell king size scarlet everlasting needs repotting

The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

Step-by-step: repotting king size scarlet everlasting

Repot dry. Do not water king size scarlet everlasting for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty lean, well-drained sandy or loamy soil, neutral to slightly alkaline ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set king size scarlet everlasting at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep king size scarlet everlasting completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for king size scarlet everlasting

King Size Scarlet everlasting wants lean, well-drained sandy or loamy soil, neutral to slightly alkaline. Rich soil suppresses flowering in favour of leafy growth. Sandy or gritty loam with good drainage is ideal. Incorporate a little grit into heavier soils at planting to improve drainage.
