Turning out a huge volume of really worthwhile articles consistently over a period of time is likely to be difficult for most people. The exceptions would be people who have been writing for years and have quite a lot of material sitting around. Our local writer's club members all have bushel baskets full of stuff they've written over the years--or massive computer files of their writings. There are some people who have written books that lend themselves to putting up piecemeal.
Most writing takes a lot of time. Most likely, the people writing about that beautiful rose actually grew it. Some of my articles (the ones on plumbing come to mind) grew out of years of experience. To write about homemade soap, you have to make a few batches of soap, etc.
There is a limit to how much you can rush this stuff.
