We would not recommend using Miracle-Gro Miracid Plant Food on either lavender or on foxglove. Lavender prefers nutrient poor soils, and too much fertilizer can prevent blooming. Foxgloves also can suffer from over-fertilization. You can use a balanced plant food for them such as Fertilome All Purpose Water Soluble Plant Food.
