dormant oil and blueberry soil acidifier
Comments (4)I am not an expert but I think you still can spray Dormant trees with dormant oil spray as long as there no bloom. I just sprayed my Peach, Plum and Cherry Trees with Copper. There is no bloom yet. But if the trees has green bloom don't do it. I know dormant oil spray like Bonide kills the leaves. Go check your local store Internet became greedy rip-off. The product cost is $10 and another $10 for handling and shipping. (that it is me ) You can use Sulfur for soil acidifier. I bought 5 pound bag from the farm store is not expensive. All I needed is one or two table spoon per plant...See Morehow to tell when blueberries need add'l acidifier?
Comments (6)If the leaves are pale green, or if they are looking yellow, the most likely cause is high soil pH. The least expensive method I have found for checking soil pH is bromocresol green dye indicator. You dig up a small soil sample, about one tablespoon, and mix it with distilled or de-ionized water to make a slurry. The slurry is then filtered though a paper filter, and when you have accumulated about 1/8 teaspoon of filtrate, you then add a few drops of dye. The solution will turn blue, at pH = 5.4, yellow at pH = 3.8, and varying shades of green if the pH is between 3.8 and 5.4....See MoreAcidifying Soil For Blueberries
Comments (22)I had a similar problem with discolored leaves on pansy plants and some other bushes also such as Ternstroemia japonica 'Burnished Gold' . I thought it could be PH, I posted about it a lot. I finally decided it was a fungal problem as using a fungicide regularly, keeps it from coming back. But if you want to eat the berries you should not spray it. It looks like the older leaves and not the younger leaves have turned, and that could be fungus. You could maybe trim off the discolored leaves, and hope for new growth. It does not look well, but I don't know blue berries. The water is san Francisco is very alkaline and they are not recommended. In fact, no one grows them here, we can grow black berries....See MoreNeed help with Acidifying soil for blueberries
Comments (7)The acidifier is not considerer a fertilizer - it is just sulfur and although that IS a plant nutrient, it is not a major one and will not contributive to excessive growth this close to fall/winter. Sulfur does take time to break down and become effective in reducing soil pH so I would apply now. There is still plenty of time before the soil cools enough and the microorganisms become inactive to get you started on the program. btw, blueberries are grown commercially in my area and we do not have overly acidic soils. The need for a very low pH is somewhat overstated. They should do very well in a pH of 6.0....See Morecapoman
