When I fertilize my Gardenia with acid food and/or iron, only part of the plant responds to it. The other half stays yellow or has the classic iron deficiency characteristics. This has been going on for two years.Why doesn't the whole plant respond to the treatment? |
Based on your description it's tough to make a guess but it is possible that nematodes are at work in the roots on that side causing an inability to take up the fertilizer. This can also cause a lack of uniformity, branch dieback or stunting in the growth of certain sections of the plant. This is more likely in a plant growing in the ground than in a pot. You might want to check with your County Extension for a more specific diagnosis. Their telephone number is 745-7513. |
