Plants In Your Home And Garden That Don't Like Coffee Grounds As Fertilizer

Tomatoes: Coffee grounds can increase soil acidity, which is unfavorable for tomatoes. Excessive nitrogen from the grounds can also promote foliage growth over fruit production, negatively impacting yield.

Lavender: Preferring alkaline to neutral soil, lavender does not thrive with coffee grounds. The acidity and moisture retention properties of coffee grounds can lead to poor growth and root rot.

Rosemary: This herb prefers well-drained, slightly alkaline soil. Coffee grounds' acidity and moisture retention can hinder rosemary’s growth and lead to root diseases.

Orchids: Coffee grounds can disrupt the delicate pH balance orchids require. The grounds' tendency to retain moisture can also lead to root rot in these epiphytes.

Sweet Peas: Sweet peas favor neutral to slightly alkaline soil. Coffee grounds can acidify the soil, adversely affecting germination and growth, and excess nitrogen can lead to weak, leggy plants.

Radishes: Coffee grounds' acidity and moisture retention can hinder radish growth. Radishes prefer loose, well-draining soil with a neutral pH for optimal development and root formation.
