Answer :

Final answer:

The advice I would give to Selena is to apply a layer of mulch around the geraniums to insulate the soil.

Explanation:

The advice I would give to Selena is to apply a layer of mulch around the geraniums to insulate the soil.

Geraniums are cool-season annuals and grow best when the daytime temperatures are between 20°C and 25°C (68°F and 77°F). Applying a layer of mulch around the geraniums can help to insulate the soil and protect the roots from temperature fluctuations, especially during the night when the temperature drops to around 13°C (55°F).
