I of late receive my first ever boysenberry plant in the postal service , and it came in the variety of a tissue paper culture .
It looked like an ordinary seedling you might buy from a glasshouse . But the possessor of the store told me that it had been spread in a lab .
When you purchase boysenberry plant life to rig out in your garden , you will usually have an alternative of a dormant spare beginning , or a small plant propagated in the greenhouse by one of four methods : a rooted cutting , tip layering , root division , or micropropagation in a laboratory setting .

It contract me curious about the skilful elbow room to disseminate this rare plant that can sometimes be hard to find . as luck would have it , you do n’t postulate access to a research lab , but you do require an existing plant .
And in none of the common propagation methods do you plant boysenberries , Rubus ursinusx.idaeus , from seed .
Why , you might ask ?
Because boysenberries are a intercrossed bramble – a cross betweenblackberries , raspberries , dewberry bush , and loganberries – and turn one from cum wo n’t produce a true boysenberry .
For this reason , they need to be propagated by a method acting that grow a knockoff of the parent plant .
Every single boysenberry bush works in the world can be trace back to the original Knott ’s Berry Farm berries .
For more on the history and cultivation of this loan-blend bramble , check out our mainguide to grow boysenberries .
Are you ready to discover the good ways to circulate these sweet , tart berries ?
Let ’s get started !
What You’ll Learn
Setting the Scene
It can get a little , shall we say , bramblyto endeavor to translate how boysenberries produce fruit . I ’ll break in it down for you quickly and simply .
First , the boysenberry ascendant and crown are recurrent , but the plant sends up new biennial stems every year . Inbramble idiom , stems are known as “ cane . ”
Primocanesare first - year canes . They ’re a invigorated green gloss and they do n’t bear any fruit , but they do rise foliage .
By the end of the first summertime , the pinnace green peel will give room to brown bark , hardy enough for overwintering .
The plants go torpid during the winter month . In the leaping , last year ’s primocanes are now in their second summertime , and they ’re calledfloricanes . Find more information on primocanes vs floricanes here .
Brown , woody floricanes produce berries on green fruiting stems called laterals .
Seven Ways to Propagate
you’re able to normally find dormant bare source plant available in the late wintertime or other spring . Transplants are usually useable year - round .
I ’m going to insure how and when to set out your purchased plants , and then go on to method of broadcast new plants from existing ace .
At the end , I ’ll make a brief citation of tissue refinement micropropagation , even though it ’s not something us home plate gardeners can seek !
1. Plant a Dormant Bare Root
A bare theme is the dormant root of a one- to three - year - old recurrent plant that has been dug up during the wintertime . You will ask it to arrive with two or more canes .
The best metre to put a dormant scanty root industrial plant into the land is at the tooshie end of winter , or in early springtime , before any Modern maturation has start .
Planting at this clock time means they ’ll come out of dormancy in time to produce a small crop the same summertime , although a full crop wo n’t arrive until the next twelvemonth .
It ’s good to expect until the follow year to harvest fruit , to let the works to become found .
If you plant unembellished roots in the summer , they may not have enough metre to fruit that year before go hibernating again in the fall .
It ’s easy to institute unembellished roots . All you have to do is happen a cheery localization in an arena with unaffixed , well - draining ground .
Boysenberry works need six to eight hours of full sun every day , and they detest have wet feet , so be trusted to embed in well - draining soil .
Do n’t fertilise the region yet , as the high assiduousness of food could drink down your dormant plant life . you’re able to , however , add several loving cup of organic compost to the hole you ’ll dig in a second .
Also , you ’ll want to plant the root as soon as potential after purchase . Who knows how long it ’s been posture in the glasshouse or store , right ? It involve a home in the dirt !
Remove the radical and cane from the promotion and hock the roots in pee for about half an hr . This gives them some superfluous moisture to take off with before you plant , and helps to remove any publicity debris .
Next , labour a hole that ’s large enough to hold the entire beginning and wide enough to allow a few inches either side .
Settle the plant into the hollow and tamp the grunge back over it in a small mound . Pay attention to where the summit is , where the stem and the antecedent link , and check that it is covered , and level with the top of the mound .
You should end up with a shallow trench around the hill of dirt . add together two inches of piddle to this deep , and you ’re done ! immature growth should begin to look within about a calendar month .
2. Transplant a Nursery Start
If you piece up a tissue paper culture , or small-scale plant at your local baby’s room or order one online , yours will belike look standardised to this .
Before you disclose it , get your planting space quick .
you’re able to transplant boysenberry bush during any time of year , but if it ’s wintertimeor temperatures regularly dip below 45 ° F at Nox , you ’ll desire to keep yours in a container indoors orin a heated greenhouse .
Plants should be transplanted in the spring two week after your last ordinary frost date . For summertime transplants , pick out the coolest metre of the daytime to put your new bramble in the garden .
Whether you ’re mature in a container or in the ground , you ’ll need to first dig a hole the size of the root chew .
In the garden , select a spot that gets six to eight hours of sunlight per day , but that also provide a few hour of shade during the hottest part of the 24-hour interval .
Since the transplant are n’t abeyant plants , you’re able to mix a20 - 20 - 20 NPKfertilizer into the soil , according to package centering , or amend the soil with well - rotted manure or compost .
softly set the plug or root ball inside the fix , and pack the soil back over it .
Now , give it an column inch or two of water . Voila , you ’re done !
3. Rooting a Stem Cutting
If a friend is kind enough to permit you take a cutting off from her boysenberry bush plant , you ’re in luck .
It ’s pretty easy to spread new plant from thinning , but you ’ll desire to take at least two to three slip to increase your chance of achiever .
The first thing you ’ll ask to do is fill several four - inch pot with asoil - free peat mossand perlite mixture , or coarse sand .
Now get out a pair of horticulture gloves andsharp pruning shears .
Next , receive several sturdy immature primocanes . Measure about five to seven inch from the tip , and dilute at an slant just under a folio bud .
If you ’d like to , you’re able to douse the cut ends in powdered rooting hormone . This may increase your chances of succeeder . try on giving one issue rooting internal secretion and leaving the others without it , and see which ace thrive !
Bury the clip cane in the potting mixture so that two leaf bud are below the territory level and at least two are above the soil line . piddle exhaustively and keep moist .
After about a month , the cuttings should be produce new leaves , which will indicate that they ’ve rooted .
At this point , you’re able to graft them into containers or out in the garden , in land amended with 20 - 20 - 20 NPK fertilizer according to package instructions , or ameliorate with well - rotted manure or compost .
4. Root Division
source cutting are unremarkably taken in the early saltation , when new growth is starting to appear . You desire to transpose the new primocanes , not last yr ’s floricanes .
Find a section of the plant with one or two cane that are between six and 12 inches tall , that seem healthy .
Cut direct down through the root and remove the cane , root , and hem in soil .
Plant in the same way as you would when graft fool , as describe above .
you may also dig up intact plant , and divide them . Just check that that each partitioning has at least one primocane . Learn perennials here .
5. Tip Layering
As trailing vine , boysenberry bush plants of course send off out runners to ego - propagate unexampled plants . But if you want to help the process along ( and be able to plant young boysenberries several feet away ) , or give plants to friend , examine tip layer .
It ’s extra well-fixed because this method acting takes advantage of what the plant is already doing naturally to propagate itself .
All you want to do is satisfy a four - column inch container with potting mix – or a larger one , if you wish – and find a long , trailing primocane .
Bury two inches of the baksheesh in the soil , campaign it parallel to the surface . Give it one to two inch of water once a week , or water more often if it starts to dry out out .
Within about a month , you ’ll have a newly rooted , vigorous plant in your container ! issue the cane about a substructure up the vine from the potted roots , free it from the parent .
Replant three to five feet off , or in another section of your yard or garden .
6. Transplant Suckers
If you see young bramble indiscriminately popping up next to your original plant life , do n’t rationalise them off !
These are true boysenberries : they ’re the product of the original flora root system of rules creating rootstock to build new roots just a twain inches forth from the parent plant .
Here ’s how to transpose the suckers to another area of your garden , where they can flourish and grow into a whole Modern Dubya for you to enjoy .
Using a shovel or hired hand trowel , dig down about three inch off from the shoot or cane that has bounce up near the parent plant .
If there are n’t three in of space between the sucker and the parent plant , plainly dig down in between the two – about three to six inches – until you find the rhizome .
With the shovel or trowel , hack the rhizome , release the patsy and its roots from the parent plant .
Carefully poke out the sucker and place it in a pail fill with water or plastered paper .
Let the sucker soak for a few minutes while you travail a muddle in your desire planting area , which should be at least three or four foot away to put up adequate space for a new plant to grow .
Dig a yap as deep as the theme clump you just pull up . Take the ascendent Lucille Ball out of the bucketful and set it in the new hole .
Tamp the crap around it and body of water thoroughly .
Now you have a gratis new boysenberry flora !
7. Tissue Culture
While tissue paper culture micropropagation is a absorbing process , it ’s hardly a method acting most gardeners could do at home . Because of this , I wo n’t explicate it in detail .
All you require to know is that it involves petri dishes , HEPA filtered tune , sterile conditions , and internal secretion .
From just one shoot , 400,000 new flora can be produced in one year !
Many of the boysenberry plants betray at nurseries have been propagated this way .
Whichever Way You Propagate, You’ll Be Berry Pleased
No matter how you settle to propagate your boysenberry bush plant , you ’ll end up with delicious fruit to eat that was grown in your own garden or backyard .
