1. Jasmine

Planting jasmine with gardenias can not only add a beautiful scent to your garden but also provide a few benefits. Jasmine is known for repelling pests like ants and mosquitoes, so it can help keep your gardenia plants safe from unwanted visitors.

Additionally, planting jasmine can help attract beneficial insects like bees and butterflies, which can aid in pollinating your garden. When planting jasmine, make sure to keep it at least 6 feet away from your gardenias, as it can spread quickly and may compete for nutrients with your gardenias.

Finally, pruning jasmine regularly can help keep it from overtaking your garden and will encourage new growth and flowering.

2. Hydrangeas

Hydrangeas can be great companions for gardenias due to their similar soil and light requirements. They come in an array of colors and can add a lovely pop of color to your garden. When planting hydrangeas with gardenias, make sure to give them enough space to grow, as they can both get quite large.

Lily of the valley is an excellent choice as a companion plant for gardenias. They thrive in the same soil ph level as gardenias, which is between 5. 0 and 6. 0. Lily of the valley also adds a beautiful fragrance to the garden.

When planting them together, be sure to give lily of the valley enough space to spread out, but keep them away from the base of the gardenia plant as this can lead to competition for nutrients.

Finally, ensure they both receive sufficient sunlight without becoming too hot. With these guidelines, planting azaleas with gardenias can create a stunning and healthy garden display.
