orange tree in self watering pot
Hi, we have a small orange tree about 16" (inches) high above the soil
level in a pot 8" high and 8" in diameter. it's about three years old. it stands just inside some french widows in a south facing location. recently many leaves have gone brown and dry at the tips for about 0.25 inches long on the leaf and then there is a part of the leaf next to that has turned yellow. the yellow part is also about 0.25 inches in length. the pot is of the self-watering kind. that is it has a reservoir of water below a grill. above the grill is the soil. so the plant is watered by the water evaporating on to the soil above. i have put some soluable photogen feed into the water recently, but only after the leaves started drying and turning yellow. does this sound simply like a short of feed problem please? or might it be something else. |

Not ideal. The roots will grow through and into the water, and citrus trees don't like that. Why they do it is anyone's guess. The best method seems to be to water it well and allow it almost to dry out, then water it again. i have put some soluable photogen feed into the water recently, but only after the leaves started drying and turning yellow. ? Phostrogen? That won't evaporate with the water, it'll just remain in the reservoir. I'd make sure there are worms in the soil and work a handful of bonemeal or hoof and horn into the surface, letting the worms gradually take it down. does this sound simply like a short of feed problem please? or might it be something else. Something else. Though what, I wouldn't like to say. -- Rusty Emus to: horrid dot squeak snailything zetnet point co full-stop uk http://www.users.zetnet.co.uk/hi-fi/ |

Put it in semi-shade to start with until it recovers. Rusty's advice is good. Pam in Bristol |

Pam in Bristol thanks to all. could you explain to a novice; does bonemeal or hoof and horn have all the foods necessary? why would these be better than phostogen? many thanks john west |

Yes - it has phosphates and releases them slowly, so one dose of bonemeal or hoof and horn will last for years. There will be enough nitrogen in it too. I suspect that there is too much nitrogen in Phostrogen. With too much nitrogen you'll get lots of soft green growth which may weaken the tree in the long run. -- Rusty Emus to: horrid dot squeak snailything zetnet point co full-stop uk http://www.users.zetnet.co.uk/hi-fi/ |
