| Hello, starfruit_1. As long as you meet certain plant requirements, camellias should not have the problems that you describe. What you need to do next is identify which plant requirements are not being met and check my section on pests. See which ones apply to your case in Hong Kong. I apologize if this answer is too long but I was trying to cover all the possible causes. While you did not state so, I assumed you planted the camellia outside and that the variety is good for planting in your zone in Hong Kong. Planting: camellias like to be planted near the top of the soil. Make sure that yours is planted slightly above ground level. Also make sure that the location you chose has no drainage issues. Lighting requirements: camellias like dappled sun or morning sun with afternoon shade. Here in Texas, I choose locations that are shaded starting at 11am because of the strong summer sun. Too much sun causes some leaves to turn a dull green, a mustard-like green or bronze color. But many times the problem is temporary. For example, plants recently moved from a nursery (where they get lots of shade) to one’s backyard (where they get more sun than at nursery) can suffer from sunburn or bronzing of the leaves temporarily.... until the plant adjusts on its own. Another example... during the winter, this also occurs when a tree that normally shades the plant looses its leaves and exposes the plant to more sun than before. As soon as the tree leafs out in the spring, this problem corrects itself. What to do? From your comments, your description sounded as if you got this plant recently so the problem may be temporary. Do determine if your current location provides morning only sun or dappled sun. If you decide it is getting too much sun, consider moving it to a shadier location. Soil requirements: camellias like acidic soil, soil whose Ph level is below 7. A reading of 7 is considered neutral while a reading higher than 7 is considered alkaline. Nurseries here in the US sell a kit to give an approximate reading of soil Ph. See if you can get a similar kit locally in Hong Kong. If your plant is starting to be affected by alkaline soil, the glossy green color may start changing as you describe, but eventually it will leave the leaf veins green against a yellowish/green leaf backdrop. If the veins and the rest of the leaf stay the same color, you probably do not have a problem with alkaline soil. The leaf color change is caused by the plant’s inability to absorb iron from the soil, a condition thus called Iron Chlorosis. Camellias which suffer from iron chlorosis have leaves whose color changes from the common camellia glossy green, to a dull green, a bronze/yellow green and mostly yellow green. The veins remain green through most of this change. This also happens in other acid-loving plants like gardenias and hydrangeas. To correct iron chlorosis, add an iron & soil acidifier into the soil once or twice a year. I use a product called Green Light Iron And Soil Acidifier. Should you have this problem, see what is available there in Hong Kong. Water requirements: camellias like the soil to be regularly moist to a depth of 18 inches (46 cm). The soil should never be dry, soggy or wet for extended periods of time. If they do not get enough water, the topmost leaves can brown out first. If they get too much water, the bottom leaves will brown out first. You will notice that the tip of the leaves browns out first until the whole leaf is browsed out. This condition is called Tip Die Back. If a whole branch browns out and dies, you may have Branch Die Back. Plants with this problem usually receive too much water and/or fertilizer. Dead or dying branches should be pruned and discarded; water less or correct any drainage problems; feed only three times a year. If the plants get too much water, root rot -a fungal disease- can also cause leaves to brown out and can also make the whole plant to eventually die. |

| Dear Luis Hello and thankyou for the detailed info. i am sorry for this late reply because there was something wrong with my internet. Actually my camellia is planted indoors in a pot. i have put it on the porch, but i'm not sure if its too much sunlight. Should i keep it at an area where there is light or actual sunlight? would you know why the leaves are turning olive green? also is there anything i can do about the new shoots drying up? THANKYOUUUUU |

| Hello, starfruit_1. Olive green Leaves: Camellias should be exposed to Part Shade (morning sun) or dappled sun. Since 6 hours of direct sun is considered Full Sun, I would make sure that the plant gets 4 hours of direct morning sun or slightly less. If you cannot find such a location, try one that has no direct light but has bright indirect light. Light reflected from a cement wall or driveway towards the plant would work as long as the plant is exposed to less than 6 hours of reflected sunlight. See my section on light requirements for other possibilities. In any case, also check the Ph of the potted soil to make sure it is not too alkaline. Dried leaves: Determine if there is a moisture problem that could be drying the leaves. As I stated before, do this by inserting a finger into the soil and determine if the soil feels dry, moist or wet. Look for indications of pests in the flowers and buds too. Finally, make sure that the pot is not located in a windy area as wind will dry up the soil in the pot very quickly. Luis |

| Dear Luis the soil is wet on the surface (as soon as i touch it) can too wet soil cause the leaves to dry? Thankyouu |

| Excellent discussion and advice. Now it is possible to lead to the root of the problem as pointed by luis. Our Camellia Society always sdvises less water may not kill a plant. The whole plant would look dehyrated and thirsty. A couple dose of deep watering will recover the plant. Yet if prolonged wet root is the cause, then the plant shall have root rot problem with prolonged sick symptom. Without actual seeing the situation, it is still hard to figure out. My question to you: Is location of the planting at lower or bottom ground area? Is it close to gutter drain direction? Get a small tool to dip the closeby area. You should find it out. I was at Sichuan Province where the ground water was very saturated. Any additional rain would cause soggy soil. They have to raise the ground for planting camellias as attached picture. You have to do a correction before the weather getting too hot Please check it with your local nursery |
