No need to add vitamins -- they don't do anything special for your garden.



Try adding a top dressing of 1/4-1/2" of well cured compost

as often as possible, assuming you're dealing with perennials. If you've got annuals, dig in as much compost as possible before the growing season, plant and keep things mulched.



HOWEVER, not all plants grow best in a highly organic soil; for instance, the roots of alpine plants may rot in water-retentive soils, and compost increases water retention. But for most common garden plants, compost is great.



Also, get a soils test (talk to your state extension agency) and fertilize and lime per recommendations.
Reply:Compost is great for building up your soil. You can buy bags of composted cow manure at the home center. Or, you can make your own. Making your own takes time and space. If it's a huge flower garden, buy it by the truckload. It's cheaper that way anyway.
Reply:Worm castings (vermiculture) is the best vitamin shot you can give your plants. But second to that would be oak leaf mulch-decomposed-black oak actually-can't be beat!
Reply:Make a compost pile of leaves and grass clippings and other materials from green weeds, coffee grounds and so forth. Let it rot turning occasionally. When it is the consistency of soil add the nutrient rich mulch to your garden.
Reply:Yes, compost or composted manure or both.
