Liquid fertilizer? Anyone have any right to the use of stakes in my garden, rain barrel, helping to fertilize, my garden plants and all vegetables grow sprouts or lawns.dont only garden plants and weeds. Weeds can be used to make a payment? or is it better to use only grass and broadleaf plants.?
Hello! Liquid fertilizer is best to collect the feces of sheep in a bag, fill the water barrel with water, then hang your purse on the water and wait for the drink, about 4 / 5 Weeks you can also fall with a horse, cut the grass and other vegetation can be used in a compost pile, but it takes much longer to reduce the two, then can be distributed over two years, it works all the best garden-John
