|I've got 3 gardenias in the front of my house . What is a good fertilizer to use because they are loosing leaves and turning yellow? I've been putting iron on it because we do have slot of pine trees but not working! I'm trying to save them cause I've already lot one! Thanks Hannah|
|Gardenias can be a challenge, but their flowers make growing them well worth the effort. A common gardenia problem is the yellowing of the leaves. If your plant is suffering with this condition it is usually due to one or more of the following:
Cold temperatures - Cold temperatures may cause yellowing of the leaves.
Poor drainage - Poor drainage can also cause this problem, so be sure you are keeping the plants moist, but not wet. Outdoor plants should be in well-drained soil. The soil composition should include a mixture of sand and vermiculite, especially if you have clay soil.
Soil lacking important nutrients ? add a soil acidifier, such as MirAcid, iron or magnesium supplements to the soil. Read all package directions carefully before application.
It's a little late in the season to do any major pruning, but in the spring you can prune your plants back to encourage healthy new growth. If you prune lightly every six weeks during the growing season you'll always have healthy new growth on your plants.
Good luck with your landscape.
