Which Blueberries to grow in zone 7a-7b

Picked the last Blueberries here today, 3 Sept; Probably Brightwell.
Picked the first, FL 96-1, about 15 June.

Yeah Iā€™d say Oā€™Neal, blueray, and sweetcrisp. Thatā€™s what Iā€™m growing now and they are all delicious. Remains to be seen how productive sweetcrisp is because theyā€™re young. Iā€™m on Daniels Road just above PVSP.

Here in zone 7a ā€¦ southern middle TNā€¦

I have 2 climax that were started in 2018.
They were my first to ripen and produced fruit 5/30 - 6/30.

Great flavor, large sweet berriesā€¦ way better than store bought. They are my older more mature bushesā€¦ the rest below are younger/ smallerā€¦ except one of my Tiffblue is quite largeā€¦ got it from a different nursery and it was large on arrival and has done well.

Also haveā€¦

4 - Brightwell. Ripened fruit 6/25 - 7/25

2 - Tiffblue ripened fruit 6/25 - 8/05

2 - Powderblueā€¦ 6/30 - 8/05.

I liked them allā€¦ absolutely no complaintsā€¦ expect the younger ones will get better as they mature.

Ranking them by flavor/sweetnessā€¦

1ā€¦ Climax
2ā€¦ Tiffblue
3 & 4 (tie) Brightwell & Powderblue

This could change as my younger bushes mature.

Yadkin is now on my list to try next time.

I gave away my climax bushes because they were so much later than my other berries. I was sick of picking blueberries by the time they were ripe. I thought the flavor was pretty decent but not nearly as good as Oā€™Neal or blueray.

Thanks! It itā€™s so overwhelming. And then being mid-Atlantic, do we narrow it down to southern or northern. LOL

FWIW, Iā€™m down the 29 a slight bit in Columbia. Spitting distance from Wilde Lake. It seems there are a bunch of HoCo folks on this board. We just moved from Nabbs Creek in AA county this spring.

My blueberries are containerized, so that affects ripening time, as does the fact I keep them in part shade. But, I picked my last Premier just 4 or 5 days ago.
My Aurora highbush has been last, but it ripened early this year for some reason. And this is only the second year Iā€™ve had the rabbiteyes here in KYā€¦but planted some in North Carolina 15 or so years ago.

My favorite is Oneal due to its superb taste but also because it is early. Most of the berries are ready to be picked before the SWD show up.

@PatapscoMike ā€¦ could be a location thing on the Climaxā€¦ I noticed Auburn gave them high Markā€™s tooā€¦ he is in ALā€¦ I am in southern TNā€¦ similar growing conditions.

Univ TN extension says thisā€¦
Recommend rabbiteye varieties for TN growers. Tiffblue and Climax are in their recommended list.

They warn that HB varieties are more succeptable to late frostā€¦ which is a big issue for me. I will be avoiding those.

They do say the HB varieties can be grown successfully in TNā€¦ but in higher elevation regionsā€¦ (cooler regions) and that irrigation system is recommended for HB.

Blueray is one of the HB varieties recommended for those type locations in TNā€¦ also Bluecrop Herbert Coville Berkly Jersey.

It gets very hot and humid here in southern middle TNā€¦ sounds like I need to stick with Rabbiteyes.

Depends on if you have room and interest in being ā€˜adventurousā€™.

For a large planting, Iā€™d do the University recommends for starters.
For home use and for curiosity sake, I try any of them.
Iā€™m even going to try ā€œEmeraldā€ if the big box store puts it on closeout.
Itā€™s a gulf coast variety.

A number of the highbush can take several degrees of freezing during bloom and still produce.

If a really cold year happensā€¦rabbiteye varieties may not survive here. But ā€˜Sunshine Blueā€™ has lived after -19 and has fruitedā€¦a southern highbush variety that I tested and like. (Used to be it listed for zones 7-9, but it does fine in 6bā€¦in fact theyā€™ve moved it to z.5-z9 in recent lists).

I try a plant of most any at least once!

A little more info I found onlineā€¦

From Univ Tenn Hort article link belowā€¦ (Dated March 2012)

Note that article is dated 2012, and it list some New Varietiesā€¦ which today are not nearly as new.

It does show that Climax is a Early Season berry and that is true for meā€¦ it Ripens first of the ones I haveā€¦ then my other varieties all ripen about the same time Tifblue, Brightwell, Powderblue (very similar ripening time, Mid season).

These are my climax berries in TN

One reason I included a couple of Tifblue in my collectionā€¦ was that one of the UT articles read said that some blueberries bloom early, some mid, some lateā€¦ but Tifblue blooms early, mid and lateā€¦ (extended blooming) so it will pollinate any others you have.

My Larger Tiffblue put out some nice sized (medium sized at least) and tasty berries this yearā€¦ and it was my longest fruting bush.

On the UT Hort siteā€¦ I found this articleā€¦

Published by : University of Arkansas Cooperative Extension Service

Which gives a farily detailed description of some of the varieties we have mentionedā€¦

@TNHunter reminded me - letā€™s see what the local extension office has to say. One of these days Iā€™ll remember to check that first :joy:

For Maryland Selecting Varieties, Planting, and Growing Blueberries | University of Maryland Extension

And again, seeing the same names come up again and again.

Thanks @RubyTue ā€” I see your article shows both Blueray and Oneal are mentioned as doing well in hot climates or being heat tolerantā€¦

When I try NHB or SHB varietiesā€¦ sounds like those may be the ones to try.
I will put them on my ā€œTry next time listā€.

Blueray and Oā€™Neal also ripen at the same time, which is nice if you want to do all your picking and preserving at once. Oā€™Neal is a week or two earlier, but close enough.

TNHunter,
Iā€™m not trying to dissuade you from planting a few NHBs, but from our experience, volume of berries produced by rabbiteyes will be 10X that of the NHBs.

We started out with NHBs, 'cause the UofKY fruit extension folks did not recommend rabbiteyes or SHBsā€¦ 10 years out, we planted a few REs my Dad rooted from his bushes back in AL (no idea what variety they were).
With 4 young kids, quantity was of utmost importanceā€¦ one of them could easily eat a gallon of BBs in a day. The NHBs were left in the dust by REs as far as productivity was concerned.
15 yrs later, we do not have a single NHB left; almost all REs and a few SHBsā€¦ but Iā€™ve mostly lost IDs, so I couldnā€™t tell you which are Climax, Premier, Tifblue, Woodard, Brightwell, etc. All taste good to me, and if you leave them on the bush to full ripeness (takes some patience, early-on, not to pick them just as soon as they turn blue), theyā€™re all sweet. Friends weā€™ve been sharing berries with this summer have raved about how sweet they are!
Kinda like American persimmonsā€¦ I canā€™t really ascertain much flavor difference from one bush to another.

Blueray, then Aurora produced the most for me this year. But my one to three year old rabbiteyeā€™s did fair for a first crop. And my Brightell died either from late cold or from too much moisture in itā€™s container from rainfallā€¦in a 10 gallon pot.

I want to strongly second everything Lucky said there about blueberries/rabbiteyes. (The only thing Iā€™m tempted to disagree about is American persimmons.) Iā€™ll add that Iā€™ve pretty much given up on growing SHBā€™s and NHBā€™s on their own roots but Iā€™m growing a few as grafts, mainly because they offer the potential for substantially extending blueberry season on the front end. It seems like early SHBā€™s and NHBā€™s can be nearly a month earlier than the earliest rabbiteys.

Hello,
Iā€™m hoping to resurrect this thread again. Iā€™ve read all responses and see thereā€™s a lot of good info here already. But, I am still confused about a few things related to blueberries and canā€™t find the answers on the internet. Iā€™m in 7a (Delaware) and am planning to plant 4 plants in the spring, each in their own 4x4ā€™x8ā€ raised bed all in a row along a fence (feedback on this plan welcome). As others have said, Iā€™m overwhelmed by choosing varieties. My original plan was to go with 4 NHB that ripen at different stages to extend the picking season as much as possible.

First questions: how do I know what is a good pollinator partner for a given plant? Is it enough to have a partial overlap in blooming period? Is it better to match the blooming period as close as possible?

After reading this thread I am now convinced that I should go with Blueray (NHB) and Oā€™Neil (SHB) for two of the plants.

Next questions: can NHB and SHB pollinate each other? Or should I pick another NHB to pollinate Blueray and another SHB to pollinate Oā€™Neil? (Note: I do realize they self pollinate but keep reading everywhere that planting next to a different variety will yield larger and higher quantity berries)

Last question: do you have any recommendations for my other two plants? I was thinking about Hardyblue because I read itā€™s the sweetest NHB but did not see anyone mention it here.

Pollination (crosspollination) isnā€™t needed for almost all Northern highbush.

Thanks @BlueBerry. But what I keep reading is things like ā€œ While self-pollinating (Duke Blueberry Plant - Stark Broā€™s), this variety benefits from cross-pollination with other cultivars, producing even larger yields.

I take this to mean that itā€™s always better to cross pollinate. Is this not true?

There are exceptions to many things that are accepted as fact. Varieties that are fully self fertile might possibly produce a little bit larger berries due to the seeds inside them all being fat from full fertilization.

But, mostly, nurseries such as Stark are hoping to sell a second plant.

(Reminds me of non-profit organizations recommending you be sure and send in your contribution before the end of the year so itā€™ll help on your income taxes. They never say, you might be better off waiting until January to make a contribution if you canā€™t use the deductions on the current years taxes!! lol)
