Will ericacious compost harm begonia busy lizzy geranium petunia lobelia etc bedding plants?

Ericaceous compost is specially formulated for acid-loving plants and may not provide the ideal nutrient balance for bedding plants like begonias, busy lizzies, geraniums, petunias, and lobelias, which generally prefer neutral to slightly alkaline soils. Using ericaceous compost for these plants can lead to nutrient deficiencies and poor growth. It’s best to use a balanced compost that meets the specific needs of your bedding plants for optimal health and flowering.
