Lemon Tree
We have a lemon tree in a pot on our terrace in Spain.
The leaves are turning yellow, it gets enough water, has stones in bottom so not water logged, situated in bright sun all day. Any ideas, Pete |

Any ideas, Pete Yellow leaves in citrus are a sign of several things but this is probably a mineral deficiency. Feed during the growing season (spring and summer) with high nitrogen fertiliser (eg chicken manure) or "citrus food". Don't overdose especially if using the granulated synthetic chemicals which is very strong or all the leaves will fall off. Several small feeds are better than one big one and water it in well. If this is the problem you will see results in a few months. If this doesn't work give them some trace element supplement. David |

They however provide food for heterotrophs like humans. While your advice may be a good thing, calling fertilizers plant food is not. People who say they feed trees flunked photosynthesis. Providing essential elements sounds like a promising treatment if they are really lacking. The problem is that no one has done optimal fertility research for trees to understand exactly what elements are lacking. No one really cares about that research. However they fund research they do not understand. Its hard to properly mulch a tree in a pot. That's you problem right there. If the pot was huge that would be better. Composted wood and leaves will provide many essential elements while stimulating benefical bacteria and micros in soil that make elements avalaible, when applied correctly. here are two articles addressing the "feeding of trees" Troubles in the Rhizosphere http://www.treedictionary.com/DICT2003/shigo/RHIZO.html Improper Fertilization (See A Touch of Chemistry) http://www.treedictionary.com/DICT2003/shigo/CHEM.html Planting http://www.treedictionary.com/DICT20..._planting.html Mulching - http://www.treedictionary.com/DICT2003/M/mulch.html Pruning http://www.treedictionary.com/DICT2003/tree_pruning Tree Farming and Related Problems http://www.treedictionary.com/DICT2003/SOUND/ Troubles in the Rhizosphere http://www.treedictionary.com/DICT2003/shigo/RHIZO.html Sincerely, John A.

However they fund research they do not understand. While you are contemplating your navel and considering the funding of research projects the OP has a sick tree.

Any ideas, Pete Citrus requires excellent drainage. In a container, citrus should have soil that is always moist but never wet. Stones in the bottom of the pot are not sufficient. You really need drain holes. Citrus also needs a slightly acidic soil with nitrogen, iron, and zinc. Blotchy yellow leaves may indeed indicate a lack of zinc. Commercial citrus fertilizers are acidic and contain nitrogen and iron, but many fail to include zinc. You may have to special-order zinc sulfate; a 1kg or 2kg bag should last for years. A pinch of Epsom salts (magnesium sulfate) now and then may also be beneficial; it should promote the branching of new shoots. Feed lightly and frequently. Always make sure the soil is moist before feeding and then water lightly right after feeding. Once the plant seems to be recovering, it should have some phosphorus to promote fruiting. Phosphorus does not readily dissolve and travel through the soil; instead, it must be placed where the roots can find it. Take a length of steel rebar or a thin stick and poke 3 or 4 holes at least 25 cm into the soil about halfway between the trunk and the edge of the pot. Fill the holes halfway with bone meal. (Superphosphate might be too strong for the confined roots.) See my http://www.rossde.com/garden/dwarf_citrus.html. -- David E.

Ross Climate: California Mediterranean Sunset Zone: 21 -- interior Santa Monica Mountains with some ocean influence (USDA 10a, very close to Sunset Zone 19) Gardening pages at http://www.rossde.com/garden/ Agree -- Yellow leaves could be caused by several things, but the most common problem with potted citrus is that they stay too moist, and yellow leaves are one indication of that problem. I think that should be your first concern, and if your pot has only stones in the bottom and no drain holes, you almost certainly have an excess moisture issue.

I would suggest you might check the ph of the soil. My water has a ph of 8
and I find that over time the soil also becomes more basic. Lemons like a slightly acidic soil and I have to regularly give a dose of acid fertilizer (once a month) to keep the leaves shiny and dark green. "bluesardine" wrote in message ...
