Very Sick Avocado Tree (Poisoned?)
Comments (3)Impossible to say with the information given. If your tree was well established and has been doing fine at this location for a few years, I'd look for something unusual (unusual weather, different irrigation, etc). BTW, the fertilizer spikes are a huge waste of money. They do a pitiful job fertilizing your trees (very likely not correct nutrient match for your tree's needs, very poor distribution of product, etc). I doubt they caused the death of your tree (unless you over applied them), but they certainly didn't help. Fertilizer spikes are truly one of the "snake oils" of today's horticulture industry....See MoreI think my first citrus tree is sick
Comments (3)Citrus leafminer attacking watersprout growth, which is very tender. Just a sign of rapid growth. You can prune back if you want, to the edge of the canopy for looks. The water sprouts will settle down on their own. You can search our forum for CLM treatments, we talk about it ad nauseum on this forum. It is mainly cosmetic and citrus growers' bane.

Comments (5)Ditto HollySprings, but it may not be as bad in Oregon. The brown rotting buds are probably from Botrytis petal blight, which develops in cool, wet weather. Copper can help control it, but you would need to spritz the buds twice a week starting when they first show petal color, if it is raining. In your climate it might be better to find varieties that are resistant, for example Tineke and Kronprincessin Viktoria among the whites. You would probably have to spray Iceberg's foliage for blackspot during spring and fall, beginning with leafout. Organic controls include sulfur, anti-transpirants, and copper (not as safe). Lose the Ortho product-- it is not a good idea to use insecticide when you only need a fungicide. The burnt leaves are from the copper. Be sure the plant is well hydrated before spraying. Spray when it is warm and the spray will dry quickly, but not when it is very hot. There are always threads on the various rose forums about disease-resistant roses, but you need to listen mainly to posters from the NW coast....See MoreNeed help with sick looking fruit/citrus trees.
Comments (6)Peach and citrus respond very well to compost teas and micro-nutrients. I would strongly suggest using a compost tea that provides both. You can easily research how to do this on your own or find a commercial tea. If you buy a tea you need to brew it I would not suggest any pre-made teas and really look at the ingredients. Believe me there are some really good teas out there but most are honestly just worm castings with one or two feed sources, which you could easily buy yourself. This is a photo of my sick peach tree. I planted this in very late spring and had bought it bare root. While it may not look like it I have been battling a serious fungus all summer. The key to this trees success has been keeping it healthy. I did this with compost tea and worm castings....See MoreRyan
