I started mine from seed the summer before last. Last year, I learned how critical it can be to spray. The leaves were eaten very quickly and the remaining leaves were filled with leaf miner markings. I began spraying when I noticed the problem, but the plants looked bad all season. This year, I began spraying right from the start (which I plan to always do in the future). I've also applied a slow release fertilizer once or twice a year. I am happy to say that this year they are already about 3 feet tall, strong, lush and healthy. I can hardly wait for them to bloom!

A traditional favorite, hollyhocks grow well here in zone 5a and come in about 60 species of biennials and short-lived perennials. The 'Chater's Double' needs moderately fertile, well drained soil and prefers full sun.
Susceptible to hollyhock rust as well as bacterial and fungal leaf spots. Southern blight is common.
To reduce the chance of hollyhock rust, mulch with straw early in the season.
'Chater's Double' produces flowers with three or more whorls of petals and few or no stamens.
As annuals, sow seed at 55 degrees in late winter, or in situ in midspring. For biennials and perennials, sow seed in situ in midsummer. If required, transplant in early autumn, when 2 or 3 true leaves have developed.
