The most likely reason for yellow leaves on gardenias is low iron. Gardenias need acidic soil, which means soil with a pH between 5.0 and 6.5. This pH range makes iron in the soil available to gardenias. If the pH of your soil is outside those numbers, you can adjust it by adding an acidic fertilizer.
How do I treat yellow leaves on my gardenia plant?
If your gardenia needs magnesium, this will cause the leaves to turn yellow. You can remedy this with a fertilizer high in magnesium, or you can add some Epsom salts to your soil. Mix one teaspoon to one gallon of water and apply every two to four weeks.
How often should gardenias be watered?

What does an overwatered gardenia look like?

How do you fix yellow leaves?
With too little water, plants can’t take up essential nutrients. Yellow leaves result. To fix or prevent water issues, start with porous, well-draining soil. If you grow in containers, choose pots with good drainage holes and keep saucers free of excess water.
Should I remove yellow leaves from gardenia?
Gardenia Leaves Turning Yellow This is normal so no need to start worrying. But if many older leaves are yellowing, your gardenia may be dying from root rot due to overwatering or poor soil drainage. Gently tip it out of its pot or if it’s outdoors, lightly dig away a little soil at the base of the plant.
Do gardenias like coffee grounds?
In addition to amending the soil with compost or aged manure, these acid-loving plants will appreciate coffee grounds, tea bags, wood ashes, or Epsom salts mixed into the soil as well. Since they are rich in nitrogen, magnesium, and potassium, coffee grounds are oftentimes a more favorable homemade gardenia fertilizer.
What is the best fertilizer for gardenias?
Gardenias use a lot of nutrients to produce so many glorious blossoms. Feed your shrubs by applying an acidic, slow-release fertilizer such as an azalea or camellia fertilizer. For the organic gardener, blood meal, fish emulsion or bone meal work well.
Do gardenias do well in pots?
Gardenia grows best in U.S. Department of Agriculture plant hardiness zones 8 through 10 , but you can enjoy these aromatic beauties indoors with little effort. With adequate water, sufficient drainage, an acidic soil and plenty of sunlight, gardenias can grow just as well in pots as they do planted in the ground.
Can gardenias get too much water?
Over-watering, for example, may contribute to poor soil drainage. This prevents the plant roots from absorbing the necessary nutrients for the plant to thrive. Generally speaking, gardenia plants should be fine with having one inch of water per week.
How do I bring my gardenia back to life?
Sometimes a wilting gardenia can be revived with the simple addition of a bit of compost. What is this? These plants are heavy feeders that should be fertilized in the early summer, toward the end of June. If you notice that the leaves of your plant are turning yellow, poor nutrition is likely the cause.
How do you save a gardenia?
The best way to save a gardenia plant from this disease is to remove the infected stems with disinfected pruners. This can be done with a 10 percent bleach solution.
How do you save an overwatered gardenia?
Rescue Techniques for Wilting Plants Move your plant to a shady area even if it is a full-sun plant. Check your pot for proper drainage and, if possible, create additional air space around the roots. Water only when the soil is dry to the touch, but do not let it get too dry. Treat with a fungicide.
Should I cut yellow leaves off?
If you have a few yellow leaves that look unappealing and bother you, it’s okay to snip them off. But it isn’t necessary. If you have a lot of yellow leaves, you’re better off finding the problem and fixing it – such as overwatering or not enough sunlight.
Can yellow leaves turn green again?
Can yellow leaves turn green again? Chlorophyll gives a leaf its green color. When the leaf loses its chlorophyll, the plant abandons it and begins to absorb leftover nutrients from the leaf. That’s why once the leaf turns yellow, you generally can’t make it turn back green again.
Do yellow leaves mean too much water?

How do you treat a sick gardenia?
Infected stems should be pruned out, taking care to disinfect pruners in a 10% bleach solution (1 part bleach to 9 parts water) or 70% alcohol solution between cuts. Avoid stressing an affected gardenia further by over-or under-fertilizing or over-or under-watering.
How much sun does a gardenia need?
Gardenias need at least four hours of sunlight daily (most blooming plants have basically this requirement, although there are exceptions). Without at least this much light, they just won’t bloom. However, in our fairly brutal summer heat, some afternoon shade will protect the gardenia’s foliage from burning.
