My recommendations are Hull Blackberry or Loch Ness and both of the newer Navaho cultivars for the home garden, especially the Bigandearly for a large patio container due to its aesthetic nature and strong uprightness. The newer Navaho types Summerlong and Bigandearly no way early fruiting! The suckers are quite spindly and easily removed mind you. Blackberry Karaka Black is disease prone and needs good soil maintenance to achieve a good yield. I noticed a lot of root rot in heavy soil and aphid attacks were very persistent.

There are several key differences between blackberry bush varieties and they can be summed up as follows: When they crop - early, mid or late season, Suitability for cooking, eating raw or both Size of the berries and vigour of the bush Disease resistance.
The reviews below are in alphabetic order. All of the varieties are fully self fertile and do not require pollination by other blackberry plants. Read also the comments left by others which can be found at the end of this article, some very good observations have been made. It then becomes difficult to prune and control.
Very few companies supply this variety for that reason. We would not recommend it. Raised in America. It is very well suited to UK conditions. One of the parents is Silvan. There are no known disease problems with this variety and we would recommend it. The flavour is very good, often compared to "real blackberry" flavour.
There have been no other reports of poor disease resistance. Raised by Dr. This is the most popular variety of blackberry in the UK and we highly recommend it. One of the parents of Loch Tay is Loch Ness. Both of those produce variable results when grown in the UK and we personally would go for Navaho Summerlong - details below relate to that variety. There are no known disease problems with this variety and we would highly recommend it.
Chad Finn, first released in This one of the earliest varieties of all, beginning to produce fruit from early July well before wild blackberries and lasting to late August. We recommend this variety, the fruits are particularly black, glossy and very easy to pick.
Reuben was raised at the University of Kansas. Reuben has lots of thorns at harvest time which is late in the season. We would not recommend this variety for the UK. This is an American variety dating back to , with the final selection being made by The Department of Agriculture in Victoria in The Oregon has small fruits and ripens end of Aug onwards, whilst the Thornless Evergreen is mid Aug onwards or even sooner with much larger fruits and more attractive pinkish flowers.
We usually use a specially selected form of a cultivar. Date: 24 February From: R. It is quite prone to both as are many cultivars. Chester is said to be very prone, but I can't say I've seen a lot in it. Chester's main drawback is about half of its huge crop fails to ripen in our climate. The fun of finding an old branch to pin back the thorns and get that elusive big berry at the top was second to none. Date: 11 February From: L. Link below shows the actual timeline of the now named JI Centre first blackberry plant releases.
Suitability for the climate. Disease resistance. Time of fruiting- earlier the better. Date: 4 February From: G. Park COMMENT : I found the birds generally leave nearly all the thornless blackberries well alone and go for the thorny types, but year in year out we have had to net our thorny blackberry plants grown only for cooking with apple of John Innes together Merton Thornless, otherwise they'd be no fruits left.
They must love the acidic taste as we do. Date: 25 January From: R. These warmer regions barely get to chill hours where Winters are usually very warm and things like pomegranates are grown widely. Date: 13 January From: Laurence COMMENT : What I like about the thornless blackberries is though they arguably may lack the real taste of the hedgerow type they don't have the need to be soaked in salty water to get rid of unwanted insects inside the fruits as is often seen after a great day brambling.
Many of the so called hardy thornless blackberries just perish in our severe winters. Only one to date and it is an old British variety has survived all including disease, yet only deemed as moderately hardy- Merton Thornless.
Its roots extend many feet deep as it is wide so that could be its secret to longevity which is 40 years now in my garden! The newer thornless ones in my trials all have succumbed to rot despite good soil drainage.
Merton Thornless has survived everything in my garden and keeps bouncing back each year to give a great crop of juicy blackberries mid Aug. Oregon Thornless is similar, but the fruits are quite smaller. If left to grow, thorny blackberries sprout all over the garden and establish.
Reason I avoid growing it as I consider it weedlike. You have to make sure it retains its thornless form by cutting out any stray thorny sucker from the roots, because if you let them grow the plant reverts to a vigorous thorny mess like a briar and fruits are much smaller.
Being a natural occurring form of the invasive cut leaf evergreen blackberry or Rubus laciniatus, it retains its thornlessness in the outer layer only, so take care not to damage its roots and remove any thorny suckers you see. There seems to be widespread variability in sold forms of Thornless Evergreen regarding fruit size, flower colour etc. Date: 5 June From: D. Soil pH can change it too. I was lucky enough to be given a commercially selected plant of Hull 15 years ago by a professional grower.
Date: 01 May From: R. The Summerlong is very stunted in growth and cane output compared to earlier years. The Bigandearly is slightly better, but the crown is woody and new cane production was low last year.
Both have petered out. Only my blackberry Chester is unchanged in terms of vigor, health, disease resistance etc after 15 years from initial planting. Date: 21 April From: G. Fantasia said to be a cross between Himalayan Giant and Merton Thornless has excellent tasting fruit too. Both of these cultivars have vicious thorns, but crop heavily.
Fifty pounds per plant is not uncommon. Best for the allotment! Date: 10 April From: B. I grew it both in a barrel and the garden for 2 years from established plant sources in a trial. The fruit quality was very bland and erratically sized. The berries had an insipid watery taste to them. They either don't flower or the crop is too light to justify ever being called a worthy fruit plant.
The Silvanberry as described here is bland to me anyway, but to others a fine taste, so much the thorns don't bother them. All personal preference! Navaho types have very tiny seeds and dont need good soil to crop well. Navaho cultivars taste superior to most blackberries because of high brix.
Bigandearly is excellent allrounder or Summerlong. Merton thornless has a fairly good flavour but hard pips and the various new and supermarket varieties are not very flavoursome. For me, the older very thorny Silvanberry is still the tastiest. Date: 31 August From: K. This year it has cropped really well from the last week in July until end of August giving big blackberries.
There are still loads of undeveloped green fruits on its stems, but with the heavy showers and lack of sun unlikely to ever ripen in this very wet Aug month. Date: 11 August From: Derek COMMENT : I have six blackberry cultivars growing in the garden and only one cultivar's berries, because they are super firm avoided grey mould, rot, and bleeding, due to the exceptional rain we are having in August in the Uk. It is Navaho BigandEarly.
The ones whose blackberry fruits are looking the worse for wear are Chester Thornless a surprise since many American journals praise how its fruits are the firmest of all! It flowers mid May to Mid June. Barely 4 weeks or so. The fruits set well and are quick forming for a late July or earlier ripening. Ideal season and good yields. Date: 7 June From: R. It is very hardy and a good grower with moderate vigor - great for a large tub.
The plant perse is highly self fertile, but its seeds are mostly sterile won't produce fruits if grown from them , so don't sow them. Its counterpart Summerlong is looking the same for this year and the yield was erratic last year. Date: 26 May From: N. The daddy of them all must be Chester Thornless. Wonderful tasting fruit, lovely pink flowers. This plant certainly lives up to its hype. Date: 18 May From: D. The only ones you see in most garden centres or big shops are Thornfree, thornless Evergreen etc.
All too late ripening in some areas of Britain and not sweet fruits. Date: 12 February From: R. I would also recommend the Medana Tayberry a hybrid between a blackberry and raspberry for good yields of 5kg or more. Thornless Loganberry proved poor for me and was replaced by this Medana. You can pick up the generic tayberry in any of those poundshops, but mostly it will grow into a raspberry and not be true to type.
Buy cheap, spend twice as they say. Date: 28 October From: S. Finding a source will be hard due to its patent. We live in North Yorkshire and the plants are at the top end of our South-facing garden, protected from the north by our greenhouses. Date: 5 October From: K. BigandEarly for 8 years and the N. Summerlong for 6 years. Approx 2 to 3 kg yields in both. I prefer the Bigandearly as the other has much smaller berries, but a more plentiful yield, if you allow its occasional suckering to take spread.
In that case you will exceed 3kg. Both are good however. A few early ripening ones were lost to hungry birds in July. My daughter bought me one a few years back after retiring. The foliage growth rate is troublesome! Find the space for it you won't be disappointed. The fruit taste is deliciously sweet when ripe and the blackberries very large. You will be picking them virtually every day from Aug until end of Oct.
Incredible plant and its flowers are a pretty pink which the bees adore. Date: 6 August From: J. I've been picking juicy blackberries as July 15th from each one. These problems are quite evident in Navaho Bigandearly, and to a lesser degree in the Summerlong cultivar. The original Navaho suffers very little from these issues apart from orange rust. Only the first fruits are worth eating fresh. The foliage growth rate is incredible making pruning tedious.
The oblong fruits are very sour in taste as leaves shield them from the sun. In the first couple of years in its establishment it did quite prolifically as I'd bought an established plant, but now it is 'behaving. Only problem encountered is white triplets on some berries in early summer from strong sunlight or whatever causes it? BigandEarly was very low yielding 1. Navaho original is orange rust prone. All grubbed out! Date: 27 April From: C. It fell out of favour with U.
S commercial growers due to hardiness issues and soft fruit, but now is primarily used for its source of thornlessness in blackberry breeding. I've grown loads of plants over the years and Merton Thornless is not far off the real blackberry taste we can all remember brambling as kids. Most of cultivars old except Chester or new are either acid or just insipid.
No blackberry wow factor. As you can guess I only grow the two mentioned, as I've the space. The Merton is a delight as it is so compact and pretty in flower like the Chester. What is the best early one out there without thorns? Blackberry Helen died out on me in an old trial and was very acidic.
My fave is Chester. The only complaint is that quite a bit of its huge yield 20kg is not unheard of! That said I've even eaten a punnet of its sweet classic tasting blackberries in early Nov in a sheltered location weather permitting. You need the room for this plant. There aren't many blackberries which can match this one.
No1 choice if you have the space. This isn't an issue for most growers in the Bay Area, where winters are mild. Growers use the canes' growth habits to distinguish between the different kinds of blackberries, separating them into "trailing," "erect," "semi-erect" cultivars. Some erect cultivars are also classed as "primocane-fruiting," an important distinction. Trailing varieties are native to much of the continent, with Rubus ursinus being the most common in the Pacific Northwest.
They grow on long canes, sometimes up to 20 feet in length, which require a trellis, arbor or some other form of support to elevate the canes. Trailing varieties aren't cold-hardy, and severe winters can kill the canes before they fruit, which can affect gardeners at higher altitudes and in colder microclimates. Trailing varieties yield large, elongated berries with excellent flavor and aroma and small seeds, so they're popular in their own right or as the base for hybrids.
Erect varieties are mostly descended from a native eastern blackberry and produce vigorous canes that grow vertically. Commercial gardeners still support them to guard against cane breakage, but that's optional for home gardeners. New canes grow from the roots as well as the crown, so upright cultivars are more prone to becoming invasive.
Berries aren't as large or as tasty as with trailing varieties, and yields aren't as high, but the berries are sturdier and less damage-prone and the plants are hardier. Erect cultivars include 'Ouachita,' 'Navaho,' and 'Illini Hardy. Mulching also promotes growth of the extensive fibrous blackberry root system.
Since the need to cultivate for weed control is reduced by the mulch, fewer blackberry roots are broken, producing fewer unwanted sucker plants between the rows. Mulch should be replenished each fall after the first killing frost.
Blackberry-raspberry hybrids and raspberries are not usu-ally as winter hardy as blackberries, and may need extra winter mulch to protect the flowering canes. Trailing blackberry varieties and erect varieties in their first year of growth may also be protected in this way.
Allow the canes to remain on the ground, and cover them with some grass or straw mulch 4 inches to 6 inches deep. Let this temporary mulch remain until buds on the canes begin growth in late winter or early spring. Then remove it and put the canes on a trellis, if needed, as described below. Apply fertilizer to the blackberry plants at bloom to stimulate plant growth, increase berry size and boost total production. Apply fertilizer according to the Table 1. First-year plants are encouraged to fill in their growing space by tipping the primocanes to encourage plant growth.
Established plants grow new canes while the old canes are fruiting. During the summer, tip the new canes primocanes , leaving them 42 inches tall for free standing plants or at 10 inches above the top of your trellis wire.
Tipping removes the apical dominance allowing the cane to develop lateral shoots. Fruit produced the following year from pruned canes will be at a convenient height for harvest. The fruits will be larger, cleaner and of better quality than if canes are not pruned. Prune out the gray-looking floricanes in the fall.
The primocanes are a green to burgundy color. Make the pruning cuts near the crown of the plant, and remove the old canes from the field to decrease insect and disease problems in the future. New canes that have produced lateral branches after summer pruning should be pruned again in late winter February or early March to simplify harvesting and increase berry size.
Shorten lateral branches to about 12 inches in length. Some new canes will need to be removed during the winter so fruit harvest will be easier the next year. This thinning will also increase air circulation, discouraging disease growth. Remove any canes that have red-necked cane borer swellings and destroy to reduce populations.
Leave 3 canes to 5 canes per linear foot of row on erect blackberries Figure 3. Leave 8 canes to 15 canes of 4 feet to 8 feet in length on trailing varieties which are to be trellised. If not trellising them, reduce to 3 canes to 5 canes.
If there are dead canes which fruited but were not removed during the previous summer, these should be removed at this time. Trailing blackberries and semi-erect blackberries need a trellis for support. This mulch can help prevent early budbreak and winter injury to buds. Floating row covers also can be used to protect the primocanes that are laying over. During the winter, the primocanes become floricanes, or flowering canes. When growth starts in the spring, these canes must be placed up on the trellis and tied loosely with natural fiber twine or with tape, which is especially made for the purpose.
New primocanes will develop at the base of the plant while the floricanes are flowering and setting fruit. These primocanes will be a nuisance when picking the fruit, but must be treated well to produce a good crop next year. This makes picking and pruning much easier than having all the canes mixed together. It also gets the primocanes up out of the way. Primocane training must be repeated every 2 weeks throughout the growing season in order to keep the canes under control.
Figure 4. A — Primocanes grow during the spring and summer, and are left on the ground under the trellis. B — Mulch can be put over the primocanes in winter to help protect against cold injury. C — After growth begins in the spring, the mulch should be taken off the canes. The canes which have changed to floricanes during the winter should be tied loosely to the trellis wires.
D — After the fruit are picked, the floricanes should be removed, leaving the new primocanes under the trellis. Figure 5. All new growth is trained to one side of the trellis, leaving the floricanes on the other side of the trellis, where they were placed the year before. Immediately after planting, water thoroughly. Drought severely decreases production and berry quality, however, excess watering can cause the roots of the blackberries to die. An appropriate pesticide should be applied at bloom time to control strawberry clipper.
Plants may need to be sprayed during harvest to control the newly introduced Spotted Winged Drosophila. For current pesticide recommendations, contact the local county Extension office. It is best to eliminate weeds before planting. After planting, kill weeds by spraying, or exclude them by blocking out the sun with mulch. Since the excellent flavor of blackberries is associated with full maturity, they should be picked at the correct stage of development. As blackberry fruit mature, they enlarge, develop a deeper blue-black color and soften.
Harvest fruit during the cooler part of the day and plan to refrigerate the berries soon after harvest. These berries will usu-ally remain in good condition for several days.
