Why You Should Plant Onions with Roses: Gardening Expert Reveals a Natural Pest Shield

Gardening enthusiasts often spend heavily on fertilizers and pesticides to keep their rose plants lush and blooming. However, the humble onion from your kitchen may be all you need to protect your roses from pests—completely naturally. Gardening expert Vinita Kumari shares this simple yet effective tip.

The Magic of Onions in Rose Gardens

At first, the idea of planting onions alongside roses might sound unusual—but it works wonders. Onions release a strong aroma that repels harmful insects, while the natural sulfur in their roots enriches the soil and protects plants from fungal infections. This method not only keeps roses healthy and vibrant but also acts as a free shield against pests.

Protection from Harmful Insects

Rose plants are often attacked by aphids and other small insects that damage leaves and buds. The pungent smell of onions acts as a natural barrier, keeping these pests away. By planting onions near roses, you can reduce or even eliminate the need for chemical pesticides.

Enriching the Soil with Sulfur

Onion roots release natural sulfur into the soil—a vital nutrient for roses. Sulfur improves soil quality, strengthens the plant’s root system, and helps the rose thrive from within.

Reducing Fungal Risks

Fungal diseases like black spot are common in rose plants. Sulfur released by onions has antifungal properties, significantly reducing the risk of infection in roots and soil. This keeps the plant healthy and extends its life.

Fresher, More Vibrant Flowers

When roses receive proper sulfur and natural protection from pests, it directly reflects in the blooms. Rose flowers grown alongside onions tend to be more vibrant, fresh, and richly colored. Sulfur also helps retain the fragrance of the flowers for longer.

How to Plant Onions with Roses

Planting onions with roses is simple:

• Dig a shallow hole about one inch deep near the base of the rose plant, keeping a small distance from the main stem.
• Place the onion in the hole—avoid deep planting, as this can harm the rose roots.
• No special fertilizers or chemicals are required; onions and roses can thrive together in the same pot or garden bed.
