Care for established lawns by mulching, aerating, weeding, grubbing and removing thatch, and trimming and edging around flower beds, walks, and walls. Mix and spray or spread fertilizers, herbicides, or insecticides onto grass, shrubs, and trees, using hand or automatic sprayers or spreaders. Mow and edge lawns, using power mowers and edgers. Plant seeds, bulbs, foliage, flowering plants, grass, ground covers, trees, and shrubs, and apply mulch for protection, using gardening tools. Attach wires from planted trees to support stakes. Decorate gardens with stones and plants. Follow planned landscaping designs to determine where to lay sod, sow grass, or plant flowers and foliage. Gather and remove litter. Haul or spread topsoil, and spread straw over seeded soil to hold soil in place
