Step-by-step explanation:
1. Margaret is wondering why her African violets aren't blooming
2. She discovered that her violets need nutrients, watering, and lots of sunlight
3. She was already following the salesperson's instructions so she decided maybe her soil was low in nutrients. She buys her plants nutrients in specific amounts.
4. After giving one of her plants' nutrients, and giving the other none she found out that the nutrients are exactly what her plants needed
5&6. I can't figure out
7. Buying her plants some fertilizer (i think)
8. Low nutrients in the soil.
9. The African violets needed fertilizer in order to produce flowers.
10. Feed the rest of her plants, and continue taking precise care of the violets.
Sorry if any of these are wrong!
