What are you weeding? A lawn? Flower beds?

If it is well fed and cared for it should crowd out most weeds,

Well, either you would need to learn more about weed prevention, maintenance- including backing up to what you have planted where, & how ( some types of plantings are more weed- friendly vs weed- hostile), or you would need to hire a real gardener/ garden service who come out, I dunno, monthly. Because I think if it as requiring multiple steps and services— assessments, getting a good handle on things ( possible spot herbicide, pre- emergents) , mulching, weeding to reduce weeds setting seed. Which could be a student, a retired garden- lover making some extra $$ and not bank- breaking , but not cheap because it’s not one & done, or a pricey landscaping svc that maintains landscapes ( I suppose more likely for clients whose landscapes they’ve installed.

I have plenty of weeds so I’m not one to talk big! I have a lot of wild- ish gnarly parts of my yard. I have several shrub/ perennial “ beds” that are densely planted ( almost too crowded) and these, with mulch, have few weeds. By I still have to weed a bit, as I have mean weeds that spread mean seeds.

A "weeding service"? That's a new one on me and I'm in the landscape business!

Are we talking acreage or a typical suburban lot? If the latter, the weeding should be easily managed provided you follow some basic practices to minimize their development.

• No bare soil exposed. Cover with spreading plants, groundcovers or a properly thick layer of organic mulch.
• Pull any weed seedlings as soon as they appear. Do not allow them to flower or set seed or the problem will be amplified.
• Use a broadleaved weed herbicide on the lawn. This will kill any weeds but allow the lawn to grow.
• Keep the lawn as healthy as possible - mow high and often, water slowly, deeply but infrequently and fertilize as necessary, preferably with an organic product that does not encourage rapid, weak growth.

If you have a larger property, there are companies that do periodic maintenance. It can be scheduled as often as you want/need but is most often done twice a year. More than just a simple weeding, it typically involves any necessary pruning, seasonal clean up and replanting, reapplying mulch and any other routine but intermittent gardening chores. Lawn care is usually a separate service but can be included in the program.

I'm suspecting spam. Expecting a link to be inserted in the OP.
