About Pot Marigold 'Pacific Beauty'
Calendula officinalis 'Pacific Beauty' · also called Pot marigold, Calendula · herb

Preferred mix: Average, well-drained loam
Why pot marigold 'pacific beauty' needs this mix
Pot Marigold 'Pacific Beauty' is a hungry, thirsty leafy herb — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Pot Marigold 'Pacific Beauty' grows fast and puts on a lot of soft leaf, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pot marigold 'pacific beauty' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves pot marigold 'pacific beauty' — growth stalls, leaves pale, and the plant bolts to seed early.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Pot Marigold 'Pacific Beauty' needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for pot marigold 'pacific beauty'?
Pot Marigold 'Pacific Beauty' does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
