During the nineteenth century the numbers of nurseries in the country increased. They varied enormously in size and success. Some were reliant on their initial owner and did not continue to do well after the owner's death, though several around Manchester carried on trading for a while, with widows and daughters in charge. Many small nurseries relied completely on the family to provide the workforce.
In April 1851 nine people were employed at Caldwell's. See Ledger 14 which shows the record of those who were employed between 26 April 1844 and 27 September 1852. Throughout those eight and a half years, the working week was six days and pay was just 1 shilling and 10 pence per day.
More information about the nursery workforce mentioned in Ledger DDX 363/14 can be found in the attached document.
