Growing Blueberries in Central Florida
Comments (27)I have just purchased a blueberry bush in a 1 gallon container - if I put it in a 10 or 15 gal pot what soil / potting mix do I buy? I am a complete newbie at planting anything so don't even know what the fertilizer numbers mean . Will I be safe to just buy potting mix and fertilizer that says it is good for vegetables and flowers? I have been reading and re-reading all these threads below but don't think I have ever seen pine fines at Lowe's (where I bought the plant) or Home Depot - should I go to a nursery for the right mix to po it in? On the plant container it mentions cross-pollinating with another BB plant - it now has berries but will it need to be outside where bees - and birds, etc- can get to it? The guy at Lowe's said I just needed a Mexican Heather planted nearby and bees will find the BB plant instead of requiring two BB plants. Will it continue to produce without the pollinization? I am so excited to be actually planting something and I love, love blueberries so I hope this will be a success and I don't kill it (the Plant and, my new-found interest in growing things). Thanks for any help you can spare...See MoreAny Blueberry Experts Out There?
Comments (8)Bill, Not an expert but have 50 or so blueberry bushes and in central Florida (citrus county). There could be a few reasons why your bushes have most probably croaked, Will list a few of the likely causes. Not sure where you bought those bushes but most times they come loaded with fruit as the sight of all that fruit sells the plants. Sadly it is much more that the plants can handle and it weakens the plants so badly that they are susceptible to all sorts of bad things. The first year the plant should not produce anything, rub those flowers or fruit off. Second year you can let the plant produce a couple dozen berries and third year you can let them have a decent crop but you always have to watch blueberries as they try to produce themselves to death. Patience now results in more fruit and a larger healthier bush. It could be a disease like scorch or a virus but if so it was probably due to the bush being weakened by bearing that crop too soon. If you fertilized them just a bit too much or with the wrong fertilizer you could have burned them to death....BB need a light hand with fertilizer the first few years. Lastly it could simply be the PH was wrong but if that was the case the plants usually languish, grow slowly and decline slowly while showing iron stress. How did you amend the soil and with what?...See MoreTechnical Question for Tomato Experts on Heat Stress
Comments (8)"I know that there are other factors that contribute to poor fruit set in heat stress, but perhaps this cross pollination technique will have a non-negligible effect .... Maybe some cultivars will be more amenable to this process than others? Anybody?" Definitely will have a non-negligible effect for the pollen, but as for fruit set, the issue will likely be 10 times more viability than zero may still be near zero if the rest of the plumbing isn't working. If it is the ovule that will not be receptive, then pollen won't help. Recognizing the differences among varieties is probably the way to go since each has its own particular physiology of what's going wrong. Varieties like Cherokee Purple hold together pretty well as do most Cherry Tomatoes. A combination approach will work best, but I tried a lot of things last summer including all kinds of manual + cross pollination and got about 10-15% set. I tried to give the pollen from the best setting (10-15% LOL) to the one that didn't at all. My biggest problem was not necessarily with the pollen, but rather the blossoms dropped off before they matured, and there is nothing I could do about that except play with shade, shade cloth and water to lower my plants' temperatures, day and night. The flower stem (pedicel) just begins yellowing before I get the chance and it is all over before it even starts. But your conditions and set failure will be very environmentally specific. Where high heat and humidity and night temp may be my problem, you may have high day and drying temperatures at times, etc., so focusing only on pollen viability would not be enough here, I can say that.

Comments (7)I wouldn't say that they're tricky. If you keep a few things in mind, acidic soil, light conditions (sunny), moisture and two varieties, the blueberries kind of take care of themselves. Like Silvia, I have an Emerald and a Jewel. When I was looking into growing Blueberries, Bamboo_Rabbit gave me a lot of information, some directly and some indirectly. I did some research on the low-chill varieties and found that Emerald and Jewel were close enough in bloom periods that they would give the best chance of cross pollination. Both last year and this year my Emerald started blooming about a week before the Jewel, which means both are in bloom at the same time. Also like Silivia, I have my blueberry bushes planted in pine fines, though mine are in-ground. There are some acidic fertilizers that can help with lowering your PH, but I have found that by using the pine fines and dropping my coffee grounds around the bushes as well as sometimes pouring pickle juice around the root zone has been enough to lower my PH to an 'acceptable' range. One big thing to avoid is using tap water for watering purposes. When the soil around my bushes gets too dry, I grab a watering can of rainwater and give them a drink. Water from the tap can be quite alkaline and using that to water your bushes would be detrimental. For the most part, however, I don't have to worry about this. I have the bushes planted on the lowest point of my yard so they get most of the summer rains and that seems to generally keep them happy. For more information than you might really want as well as a lot of good tips on lowering your pH, do a forum search for Bamboo_Rabbit and Blueberries. Two posts in particular to look for area Blueberry Lovers and Growing Blueberries in Central Florida. Oops, I totally messed up and linked those posts making it too easy to find them! Enjoy. Oh, and rather than letting the berries go to wildlife during their first year, it is better to just remove the flowers/berries for the first year and let them put all their energy into establishing themselves....See Moreibarbidahl
