Why plant Diamond Spire™ Gardenia?

With bright and dazzling white blooms, the Diamond Spire™ Gardenia will wow visitors year after year!

How To Plant Diamond Spire™ Gardenia

Your Diamond Spire™ Gardenia prefers a spot in full sun but can handle a bit of shade, especially during the afternoon, when the sun is the strongest. Apply a layer of mulch about 1-2'' deep around the base of the plant - this will help keep the roots cool during summer, as well as maintain moisture.

How To Water

Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water slowly and thoroughly. Watering needs may be altered due to extreme weather conditions.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each year. Continue this for three years to get your plant well established.

How To Prune

While your Gardenia will not require much, prune as needed in late winter.
