Yes, lettuce may need fertilizers if soil analyses indicate nutrient deficiencies and pesticides if the leafy vegetables suffer from pathogens, pests and weeds. Fertilizers and pesticides operate as double-edged swords in blocking and creating problems that may not arise or continue with proper attention to the site's heat, light, moisture, nutrient and pH levels. Lettuce tends to be calcium-, iron-, magnesium-needy and nitrogen-, phosphorus- and potassium-sensitive -- all of which will be delivered by compost, organic inputs such as blood meal and mulch -- and aphid-, armyworm-, corn earworm-, cutworm-, darkling and flea beetle-, grasshopper- and maggot-vulnerable, all of which will respond to organic treatments such as horticultural oils and insecticidal soaps.
