About Eschscholzia californica 'Thai Silk Rose Chiffon'
Eschscholzia californica 'Thai Silk Rose Chiffon' · also called Thai Silk Rose Chiffon Poppy, Semi-double California Poppy · flowering
'Thai Silk Rose Chiffon' is a compact California poppy with semi-double, fluted petals in soft rose and cream over blue-green ferny foliage. A tough, drought-tolerant hardy annual, it thrives on poor, well-drained soil in full sun and self-sows freely. Easy and pollinator-friendly, it contains alkaloids, so keep pets from grazing it.
Growth habit: Low, bushy and slightly spreading with finely cut, blue-green foliage and upward-facing flowers on slender stems. Self-cleaning in effect, and a prolific self-seeder.
Watch for — Few flowers, lush leaves: Caused by rich or over-fertilised soil. Grow on lean, poor ground and never feed for the best flowering.
What fertiliser eschscholzia californica 'thai silk rose chiffon' actually wants — and why
Eschscholzia californica 'Thai Silk Rose Chiffon' flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.

How often to feed eschscholzia californica 'thai silk rose chiffon', and which months

Needs no feeding and prefers lean soil; fertiliser produces leafy growth at the expense of flowers. Skip feeding entirely in beds and use only a very weak feed, if any, in containers. In practice: no routine feeding at all for eschscholzia californica 'thai silk rose chiffon' — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.
The dormant-season rule matters more than the exact interval: skip feeding entirely when eschscholzia californica 'thai silk rose chiffon' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
