Annuals for hot, dry areas receive irregular watering and intense heat. Some include amaranthus, atctotis, centaurea, convolvulus, coreopsis, California poppy, rudbeckia, tithonia and verbena. Garden Flowers - Soil Preparation Soil preparation includes removing weeds, debris, etc., amending soil and adding fertilizer for the development of healthy plants from the start. Read sowing directions as some are sown deeper than others and some are broadcast. Following either direction, firm soil and water evenly and consistently for best results.
Ingredient numbers show the amount of each.
Site preparation should include all three ingredients especially potassium and phosphorus as they are needed in healthy plant development. Dry fertilizers are great for preparing soil previous to planting. Liquids are easy especially for container gardening. Read the labels because some are complete and some single nutrient such as fish emulsion dissolved in water. Time released fertilizers shouldn t be used in the seeding stage because of the time release factor and would slow the beginning growth but are easily added thereafter and will not burn the flowers as some dry fertilizers do.
