Frost Proof Gardenia




Blooms When Others Don’t

You’ll never miss a Gardenia season because of late cold snaps.

Ordinary Gardenia buds can freeze and never develop into flowers. So, you get a skimpy showing or no blooms at all.

Frost Proof bushes are smothered with amazingly fragrant blooms every year. They stand up to the cold and unusual weather patterns.

Mid-West or Key West…Frost proofs pump out blooms that fill your yard with that distinctive Gardenia aroma.

Deer resistant and trouble-free. Thick Green foliage makes it versatile enough to be a foundation hedge, property barrier or the focal point of a berm.

Planting & Care

Frost Proof Gardenias (Gardenia jasminoides ‘Frost Proof’) are prized for the strong sweet scent of their flowers, which grow to be 3-4 feet tall and 3-6 feet wide. The Frost Proof Gardenia was first cultivated as a house plant. Gardenias usually demand high humidity to thrive, and bright (not direct) light. They flourish in acidic soils with good drainage and thrive in 68-74 F temperatures during the day and 60 F in the evening. The benefit of a frost proof gardenia is in its name – they have been bred to adapt well to cooler climates. Flowering occurs mid-spring to mid-summer and the Frost Proof Gardenia is strongly scented.

*In warm weather areas, gardenias will do best if given morning sun exposure and afternoon shade.


Planting instructions:
1) To plant, dig a hole no deeper than the root ball and two to three times the width of the and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, improve the drainage in your bed, perhaps by establishing a raised bed or amending soil with sand, stone or perlite.
2)Turn and break up the soil removed from the planting hole. Mix some organic compost if the native soil is clay or compacted soil.
3) Remove your plant from its container and carefully, but firmly loosen the root ball. Set the Frost Proof Gardenia into the hole you’ve prepared, making sure the top of the root ball is slightly above the soil level.
4) Put your back fill soil mixture around the root ball in the hole, tamping as you go to remove air pockets.
5) Water thoroughly and cover with a two to four inch layer of mulch.

Watering: Be sure to keep your Frost Proof Gardenia moist but not soggy. Do not let it dry out between waterings as this stresses the plant. You can rely upon natural rainfall, but use a rain gauge to measure the amount of rain your gardenia receives. If the gardenia is receiving less than an inch per week, supplement it with water from the hose or from a watering can.

Fertilization: Feed the Frost Proof Gardenia bi-weekly with non-alkaline fertilizer. A teaspoon of agricultural sulfur in the soil may help lower soil pH. Fertilize gardenias after they’ve bloomed with a well-balanced shrub & tree type fertilizer. If the foliage on your gardenia develops yellowing of the leaves then the soil may be too alkaline. You can apply additional amounts of chelated iron and/or soil sulfur to lower soil pH, making it more acidic.

Weed Control: Applying a two to four inch layer of organic mulch will help retain Frost Proof Gardenia’s moisture during this time and will also help to keep down the competing grasses and weeds.

Pests and Disease: One of the biggest problems for Frost Proof Gardenia are the pests that plague them. The major pests to watch for include: Aphids, Mealy Bugs, Scale, Root Nematodes, Spider Mites and White flies but all are treatable with pesticides found at your local gardening centers.

Pruning: Frost Proof Gardenias require no pruning. To maintain shape, prune in late winter before new growth emerges. Cut with hand pruners, and not powered trimmers, to avoid scarring leaves. Sterilize your cutting tool(s) with rubbing alcohol to eliminate the possibility of pathogens getting at the plant.
