When do i plant dahlia bulbs

Bait for slugs as soon as growth appears, but wait to water until the new growth reaches 6 inches high. After that, water regularly to keep the soil evenly moist at all times. Every six weeks, work a mixture of 2 cups of alfalfa meal and about a cup or organic flower food around the drip line of the plant.

Then, as long as you deadhead spent blossoms often, your dahlia should pump out spectacular blooms all summer long. Keep the soil evenly moist and fertilize only once by mixing in a cup of organic vegetable food at planting time. Q: Is it true that corn gluten is a natural product that will keep chickweed and other low-growing weeds from taking over my vegetable and ornamental flower beds?

At the same time, they also discovered that corn gluten is beneficial to existing plants by acting as a potent fertilizer. Not surprisingly, corn gluten was patented and is now available as a popular environmentally friendly alternative to using chemical pre-emergent weed controls.
