About Bon Bon Mix Pot Marigold

Calendula officinalis · also called Pot Marigold, Common Marigold · flowering

Bon Bon Mix Calendula is a compact, dwarf pot marigold bearing fully double blooms in vivid orange, yellow, and apricot tones from late spring through autumn. A tough, cool-season annual that self-seeds freely and is edible. Listed by the ASPCA as mildly toxic to pets — ingestion may cause mild skin and gastric irritation.

Mature size: 25-30 cm tall, 20-25 cm spread

Watch for — Failing to flower in summer heat: Calendula is cool-season; plants slow or cease flowering when temperatures exceed 27°C. Resume sowing in late summer for an autumn display.

Indoor size vs how big it gets in the wild

Bon Bon Mix Pot Marigold reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 25-30 cm tall, 20-25 cm spread. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Its feeding profile backs this up: a single application of balanced granular fertiliser at sowing or transplanting is usually sufficient in average soils. in very poor soils a monthly dilute liquid feed (npk balanced) keeps plants productive. avoid high-nitrogen feeds.
