I recommend a time release product. Make list and decide on strategy. We garden organically as much as possible and I am willing to allow some insect presence. Decide on color scheme. Select seeds for summer bloom, prepare planting beds and sow.
Good candidates are pansies, snapdragons, zinnia, .
Spray Round-Up to remove large areas of unwanted vegetation. Cut down large weeds with weed eater. Cultivate Soil- spade small areas, turn large areas with tractor and use rototiller for vegetable bed. Add layer of sand and compost to perennial garden then lightly cultivate. At great time to plant.
