Loss of vigor? (Sue)

I've had this Navaho Summerlong plant for 2 years now and fertilise the soil every year, but for some reason the plant has lost its vigor and is looking a bit lifeless. My BigandEarly is also having a problem with pale green leaves like chlorosis, but no loss of vigor. My Merton Thornless is looking healthier/no aphids which is a surprise as it is planted near it. Could it be aphids as both Navahos have been attacked by them this spring mostly infested the ends of the canes?

 
May 31, 2017

Vigor? (John)

Try tomato feed for the BigandEarly. Regarding Summerlong it could be root rot or a drainage problem due to heavy soils as it does not seem to like as much as other Navaho types. Aphids are a problem with every blackberry. Spray before flowering each year.

Jun 12, 2017

Vigor loss! (Malcolm)

You never said where you're growing it. Summerlong in my experience is not suited to heavy soils or containers as it is somewhat susceptible to root rot causing loss of vigorvigor and cane dieback. BigandEarly is suited to any condtions in the UK. Try bonemeal fertlizer, if tomato feed does not improve leaf colour.

Jun 18, 2017

Root Rot in Summerlong? (Heath)

I have to agree that blackberry Navaho Summer long is prone to root rot, but only in a container grown environment thus making the plant decline in vigor. In the field/garden it appears to be equal to BigandEarly in terms of root rot resistance in a well drained soil.



Therefore I cannot recommend Summerlong for the patio in a container. From my tests it dies out over a few seasons of wet winters. BigandEarly is resistant to all adversities of weather, fungal/viruses environment and seems to have inherited much more of the original parents Navaho/Loch Ness combined disease resistances than the Summerlong, however BigandEarly is more susceptible to chlorosis than it.

Mar 6, 2017

Invasive roots? (Karen)

Is this plant's roots invasive in the garden or should I plant in a large container? Thanks

 
Apr 12, 2017

Suckering! (Michael)

Hi,
Cut out the odd root suckers which are spindly, slow growers anyway/not worth keeping. Yes it can sucker if the soil is rich and ideal, but not to a great extent like the wild blackberries which colonize an area within a months. Plant it in a large container and no problem!

Feb 17, 2017

Fruiting season length? (Tony D)

Hi, How many weeks does this plant give fruit for? Thanks.

Most disease resistant? (T Steel)

Which Navaho is more disease resistant, BigandEarly or the Summerlong? Thanks.

 
Dec 18, 2016

General Info (Terry Steel)

Guess you guys must be far too busy to answer specific questions and I read the Navaho plant reviews and most are positive. No problem, but in anycase I bought a blackberry Waldo instead.

Jan 31, 2017

Disease? (A.j)

Can't speak for the Summerlong, but the BigandEarly has excellent disease resistance to everything. Root rot killed all my other blackberries off (Chester, Waldo)a few years back, but not the BigandEarly which was quite near them. Impressive plant, grown in either a large tub or the in the garden!!!! I will say that it does sometimes get white druplets, but I saw this in every blackberry I'd grown, mostly due to rain on berries then sun scorching them.

Feb 9, 2017

Disease Resistance! (Deepak)

BigandEarly has the better resistance. Navaho Summerlong has moderate susceptibility to root rot in my tests more so with younger plantings, but established plants have high tolerance to either phytophera or armillaria in heavy water logged soil due to prolonged rain. Navaho BigandEarly is exceptional it can be planted in pure clay, made subject to rain over winter and still be healthy and resist all fungal leaf diseases extremely well. Navaho BigandEarly also fruits much later in the UK: end of July, Summerlong mid July .

All Navaho types have slight tendency to white druplets, not a big issue as it is seen in most blackberries and is severe with blackberry Apache. sometimes the odd druplet on berries can be sterile(pollination issue?) leading to misshapen berries in Navaho crosses but not with Luberas newer cultivars of blackberry which have high flower self fertility . This is an issue more with original Navaho but then again does not happen every season. BigandEarly for resistance and Summer long for higher yield.

Navaho Container suitability? (Darren Smith)

Hi, after unsuccessfully growing blackberries in a large pot container 50 litre capacity, I would like to know how suitable BigandEarly is to this type of growing? My last attempt was a Lubera Navaho Summerlong which rotted over last winter and died after appearing dark mushy, brown on its canes and roots. Phytophora rot? Previously a Black Satin and an Asterina died too. I always disinfected the container and used sterile soil, but the heavy rains in Winter and frost always kill my plants. Navaho BigandEarly is going to be my last attempt as we have no room in our garden so only can use containers. Thanks for your help.

Cane Borers/Vine Weevils in container? (John)

Hello,
I can identify this as container growing of any plant is a tricky business. More likely your plant(s) fell prey to nasty vine weevils which suck the life out the roots when they hatch out of their eggs, thus the plant dies and goes a horrible brown/orangey colour(roots as well) regardless of winter conditions. Or you had bad drainage in your container, which is unlikely.

The vine weevil is an awful enemy in the garden, in pots use natural nematode products like Nemasys for your fruit plants harmless to us but not to them. Never use pesticide of course if the plant/fruit is edible. As space is a problem this is your best option, also plant chives or cloves nearby weevils hate the smell. My strawberry plant Hapil was decimated in its pot by those things this summer. Perhaps Lubera have their own special way to deal with the weevil?

" More enemies in the garden than friends" my grandfather used to say! Good luck.

Nov 18, 2016

Navaho Container suitability? (Philipp Schneider)

Dear Mr Smith,
BigandEarly is suitable for container growing. In winter you can protect the pot by placing it next to the house wall. If the rain still flood the container, protect it against too much rain as good as possible with some plastics. Frost shouldn't be a problem in Great Britain if the container is located next to a wall and a bit protected.
And yes... there is a BUT: If you had so many disappointings with blackberries, maybe it's a better advice to suggest using another plant.

Nov 5, 2016

How close to plant? (Simon)

Hi, how close do you recommend planting these varieties please i.e. How much space to leave between bushes. Also, is some form of support useful or do you grow completely free-standing? Many thanks.

 
Nov 8, 2016

how close to plant (Sonja Dreher)

Hello,
the Blackberries will need a form of support , a trellis or at least a post, where they are tied to. The shoots get to long and if there is some stronger wind they will probably break.
The space between the plants in a row should be 80 cm minimum.

kind regards
your Lubera Team

Nov 17, 2016

Spacing (John)

Hi,
With Navaho BigandEarly you will get away with a minimum 2 feet spacing between plants, if your desire a hedge effect, as the plant is nicely compact growing. 2.5+ feet((80 cm or so) is optimum. Remove the lower branches/side stems less than waist high so growth is more upright. Always use a stake or similar(wigwam effect) to stabilize canes. This is not because the plant is weak etc, but to provide protection from strong winds, and help you pick the fruit better in summer.

Sep 17, 2016

Re:Parentage (Sue)

Hi, Are Lubera's new selections Summerlong & BigandEarly hand pollinated natural crosses like original Navaho was? Thanks.

 
Oct 20, 2016

plant hybrid (Anon)

Yes, hand pollinated from what I'd learned. Is it me, but these questions on Lubera plants here(any plant) never get answered by this site in recent months. A very Dead so called 'interactive' forum and most disappointing for potential customers! Even posItive comments added never appear!

Oct 21, 2016

Parentage (Philipp Schneider)

Hi.
Yes, ALL YOUR plants are hand pollinated natural crosses. We do NOT use gen modification.

Best regards,
Your Lubera-Team.

Nov 17, 2016

True to type? Yes! (John)

Absolutely true to type, if the vendor from whom you buy sells the original! No worries there. Buying direct from Lubera is a guarantee as their plants are sourced and natural crosses, none of that genetic nonsense. That is why I like their plants.

Navaho Summerlong parentage? (Derek)

Nice site, very colourful. I've been growing Navaho Bigandearly and Summer long for quite a few years and notice there is quite a difference in them. Reading here Blackberry Lochness is part of the original cross and Mr Kobelt mentioned it in one of his earlier videos about plant breeding. Is there another plant in the cross? Bigandearly never suckers from its roots in my experience just crown suckers new canes, but Summerlong suckers prolifically from its roots several feet away when established as well as its crown. Is Blackberry Arapho in the Navaho Summerlong cross? I grow Arapaho too and it resembles Summer long in many ways especially in fruit size. I like both plants very much, but think Bigandearly is the better for the home garden. It gives me yields of 3.5 kg consistently ever year, and Summerlong can be double that sometimes due to cane growth and spread. Thankyou.

 
Jul 21, 2016

parentage (Sonja Dreher)

Hello,

happy to hear that our Blackberries are a success in your garden.

Both Bigandearly and Summerlong are Navaho x Loch Ness crosses.

Suckering (Jim )

Yeah, I noticed the free suckering in Summerlong variety, but these offshoots are pretty weak growers, so let them grow a bit and cut them out close to its roots. I wouldn't keep them as it would be a very long time(years!!!) for them to establish new plants, also they take nourishment from the crown of the Blackberry, so bin them. I was very happy to have received big established plants from Lubera, some companies only give you small cuttings! BigandEarly rarely suckers in my experience except in lighter soil, but is a delightful plant to grow in the garden by a sunny wall or in a pot.

Hardiness of Navaho Summerlong (Peter)

Hi, I have a question regarding hardiness of this new variety - what equivalent of USDA zone it is hardy in? Does it retain the original hardiness of Navaho?

 
Jan 19, 2016

Navaho hardiness (John)

I now grow both Navaho Bigandearly and Summerlong types. In answer to your question yes, very hardy, and probably even better than the original Navaho parent. Put it this way they say blackberry Chester is the hardiest of all thornless types. Mine totally succumbed to the heavy frost of 2014, and a different planting of Chestsr along with a blackberry Asterina in the garden fell to the already awful waterlogging accompanied with -5 celsius freeze we have had this year so far in the UK.

Both my Navahos are still evergreen and unaffected! Zone 5-9 is my educated guess and temps until -26 Celsius before some cane damage shows. Root rot resistant and immune to orange rust too!

Jan 20, 2016

Hardiness of Navaho Summerlong (Daniel Labhart)

Hello, Summerlong is as hardy as Original Navaho. It can stand "normal" winter temperatures in Europe. Til -15 C is not a problem, but where you can expect regularly temperatures below -20 C I would not plant it.

Jan 21, 2016

Very hardy plants! (W. Henderson)

Hi, I grew successfully Navaho Bigandearly in protracted temps of -25 celsius, sometimes -30 Celsius for weeks on end and canes incurred NO visible damage. The winter chill gave huge crops in July. Summerlong will have a similar hardiness ergo as it has same plant genes. Don't worry these plants are virtually indestructible!

Aug 9, 2015

Soil adaptability? (Mark)

I grow both Bigandearly and Summerlong varieties in Scotland, for me Summerlong is the better one because of its even flowering, and fruiting is consistent giving typical berries of sizes 4g to 5.5g. What I have found is Bigandearly thrives in very heavy soil(only place in the garden to plant it), but its fruit ripening becomes later due to the development of larger berries 5 to 7.5g. Summerlong was planted in a much lighter soil because of space issues. It seems to like as it produces the odd root sucker away from the crown. Both are in full sun aspects with Bigandearly not suckering because of heavier compact stony soil? How does Summerlong react to heavy soil conditions in your tests? Thankyou.

 
Aug 17, 2015

Adaptibilty (John)

Any soil in my growing experience as long as it has a bit of goodness and periodic nutrition thrown in as blackberries quickly exhaust their soil.

Aug 18, 2015

Soil adaptability (sonja dreher)

Hello,
of our Navaho varieties "Summerlong" and "Original" are the stronger growing ones. Sure it can be, that the soil also has an effect on the growth, but we have not made any tests yet, considering that matter.
So if you would like to report your experiences to us, we would be pleased for sure. :-)

Dave (Kellet)

Hi Your description of Summerlong says "moderately sweet" while Bigandearly's is "sweet" is this a big difference in berry taste? Thanks.

 
Jun 24, 2015

Blackberry Navaho (Your Lubera Team - Sonja Hendrischke)

Hello,
the difference in taste is just the relation between sweetness and aciditiy in each fruit. It depends on everybodys peference.

Summerlong Navaho (Peter Thompson)

I planted a Navaho Summerlong in my garden late summer, after reading about the Bigandearly plant can I expect the same level of resistance to fungal diseases or plant viruses, plant vigor, adaptibily to different soil pH, for future seasons? Lubera's video on the differences between these two plants only mentions the amount of yield/hardiness and does not explain this. I've tried many thornless blackberries and eventually after 10 years they all succumbed to virus. Thanks.

 
Dec 15, 2014

Summerlong Navaho (Your Lubera Team - Sonja Hendrischke)

Hello,
both blackberries are as healthy, resistent and vigorous.
Bigandearly has a very concentrated cropping period, which is in July and has the biggest fruits of the Navaho family.
Summerlong is cropping from July until August and has a bigger crop.

Navaho Bigandearly and Summerlong (Alex)

Are this two blackberry plants suitable for intensive agriculture purposes? I would like to know how productive this two species are. Thank you.

Blackberry Navaho family agricultural suitability (Rick)

Tricky question??? Possibly the original Navaho as that has been tested commercially, but these 2 new offspring cultivars could have some potential especially Navaho Summerlong due to potentially heavier/longer cropping ability but I find Bigandearly to have great merit too. Trial data is down to the original nursery I'm afraid, if available? From Lubera!!!

Nov 8, 2014

Blackberry Navaho family agricultural suitability (Rick)

In my observations winter chill requirement in both is around 700 hours less than parent original. Bigandearly can crop up to 2kg, Summer long 2 to 3.5kg due to longer season giving berries around 6.5g size. Bigandearly produces whoppers around 8g early on in July. Zero disease resistance is much stronger than parent. Big and early is more visual to look at due to super pinkish rose type flowers.

Navahi Bigandearly (Your Lubera Team - Sonja Hendrischke)

Hello All,

up to now we don't have any trail data about agricultural purpose of our Navahos.
We rely on the good experiences our customers report to us.
As our intension is to make better plants for the home garden, the agricultural aspect is of no big importance for us. Of course we are pleased, when our plants are an option for professional fruitgrowers.

Kind regards

Hot Climate Suitability. (Mehmet)

Is Navaho plant suitable for hot places like Turkey?

 
Nov 8, 2014

hot climate suitability (Rick)

Most definitely Chester thornless with winter chill requirement of 850 hours below 7 Celsius to achieve rest and budbreak thrives in central Turkey I'm told. Big and early most likely has a bit less requirement than 700 hours in my tests using 3 celsius as an inception point of chill and earlier budbreak and flowering period corresponds with this, but summer long was around this figure not disproportionately. Just make sure they get plenty of water due to humidity. Big and early is much more drought resistant than Summer long by the way.

RE: Aphid Resistance (John)

My pleasure!

 
Jul 11, 2014

Aphid Resistance (Dave Marshall)

I already bought your excellent Navaho Bigandearly a few years back and now have just bought your Navaho Summerlong. My question is that Mr Markus revealed in one of his video blogs that your strains of Navaho were mixed with the Loch Ness cultivar, and obviously some of that cultivar's attributes along with thornlessness etc were passed on, but I see in my plants growing, that Bigandearly is massively an aphid magnet yet Summerlong never gets bothered by them at all, in fact the leaves are remarkably bug free- I just wondered why, could another plant in its gene pool be giving more resistance to the Summerlong? P.S I also learned from experience that Bigandearly really thrives in heavy soil. One planting in light soil totally died over winter, but the other in our heavy clay type soil(iron ore based) really took off. Thanks Lubera Team.

 
Jul 12, 2014

Aphid Resistance (Your Lubera Team - Sonja Hendrischke)

Hello,

as you wrote, the Bigandearly really thrives in the heavy soil.
The aphids are always attracted by the juiciest plants they can find. This is the reason why Bigandearly is their favorite.
There is no such thing as resistance to aphids. (despite from some salad varieties - but with no good results).

Aphid resistance (John)

Hi there,
Quote: "There's no such thing as aphid resistance.."

That's not strictly true as breeders have found some resistance to aphids in strains of black raspberry and are trying to implement this into modern rubus breeding as we speak.
It is quite feasible to surmise that certain breeds of rubus/or ones which have specific genes in them are favored by these green critters more than others due to unique genetic makeup/markers in the structure of leaves which can make them more attractive to pests.
