young raspberry plant

If you own a raspberry plant that bears berries with a true raspberry flavor, you may have been searching for this natural raspberry variety for a while. If replenishment becomes difficult, only propagation can keep the true raspberry flavor in the garden... If you have purchased a brand new premium variety and want to replant your property with these raspberries, multiplication would also help, even their account balance; Unfortunately, it is not certain that the premium variety grows well outside of a laboratory.

Why multiply raspberries?

Maybe you were lucky from the start and your first raspberry from the garden center next door feels great in your garden and garden floor and bears fruits full of raspberry aroma. Then it is of course more effective to buy in the garden center for a few euros the next raspberry of this breed. Propagation is more of an option in this case for parents who want to familiarize their children with the plant world or for home builders who want to provide long-yards of unfounded fence with a cheap planting.
However, the career of the average raspberry farmer looks a little different: He sees a beautifully grown raspberries z. In a catalog that carries large red fruits whose intense taste is emphasized. In the garden, this raspberry grows quite nicely and actually bears large red fruits, but their taste is clearly more in the direction of watery than in the direction of "intense raspberry flavor". This is followed by a time of good advice ("Do not water so much before harvesting," "There are no trace elements", "Did you apply raspberry fertilizer XY?"), Whose adherence to the raspberries does not bother. Then the next cultivars move in until eventually there is a raspberry plant underneath that bears raspberry flavored fruits.
This raspberry plant usually comes no longer from the garden center next door, but as an offshoot of friends / neighbors, from an eco-garden or as an insider tip from a plant exchange. It can not be quickly bought, here you will only continue to propagate.

With freshly planted raspberries you should wait with the propagation until they bear full fruit: Regardless of whether you have "guaranteed disease resistant" raspberries bought and planted or just raspberries (without a thought to raspberry diseases to waste) - before a multiplication should adult raspberry should be examined closely for signs of fungal or other infestation. In the case of the "guaranteed disease-resistant" raspberry, you then know whether the trader also meant the diseases in your region, in the case of the "simple-so-raspberry", whether it was a stroke of luck or attracts mushrooms; In any case, you should only multiply tested healthy plants.

Raspberries multiply themselves

If a modern raspberry variety is to be propagated, you are dependent on vegetative propagation; d. H. You must try to get a clone from the plant.
The modern cultivars are usually produced in the laboratory or in a selection of breeding bricks in the quick process, important plant traits remain here more often on the track. Highly endangered are the resistance and the ability to produce phytochemicals (which are responsible for the "real taste"), because both are sitting on many different genes; Frequently the reproductive capacity of the plant is also affected. The breeding plants sometimes do not grow seeds any more, sometimes they do not develop properly, and sometimes they germinate splendidly, but do not necessarily produce plants of the variety to be propagated (if a cultivar was advertised as F1 hybrid, that is for sure, this first Crossing step is for traditional breeders nothing more than the first step on the long way to the pure-bred breeding plant, more about modern breeding you will find below).
So the modern cultivar needs to be asexually vegetative (via growth), which will not bother you if it's just about more harvesting the same raspberries. Plants can be "cloned" from different parts, for raspberries the following methods are available:

1. Propagation by sinkers

Lowering is meant here literally, especially autumn raspberries are to be persuaded to produce new plants by laying a rod on the ground, fix there and cover the place with soil.
When roots form, new leaves soon form, the small raspberry can then be pricked out in the spring and planted in its own location. When a variety forms lowerers, you can start propagating throughout the garden year.

2. Propagation by cuttings

Crop replanting works a bit differently with raspberry than the seasoned gardeners are used to because you can not cut cuttings from the plant itself.The shoots of the raspberries are not normal branches, but aboveground continuations of the earth sprouts known as rhizomes, which die off after fruiting; they are not intended for propagation or rooting in any other way (which is why raspberries are not actually propagated by sinkers; because they are so different, the shoots of raspberries are called by the skilled person "rods").

Multiply raspberries

So the cuttings are taken from the root here, several pieces about 10 cm long with at least one eye or just a piece of root, which is tapped by the rhizome of the raspberry in late autumn. The plant parts are placed in a cultivation bed with humoser, loosely adjusted soil by sand and are covered with a mulch layer. After one season at the latest, the plants should have developed new plants, which you can transplant to your desired location.
tip
Propagation over rooting plant parts is part of the daily bread for most plants of our planet, eg. For example, to survive until evolutionary sexual reproduction has succeeded. It was until recently also the daily bread of the house gardener (instead of spring large purchase in the garden center), is in the case of the modern cultivar no longer in each case a successful way. If "fast-and-dirty-breeding" has been grossly interfered with in the genome, modern breeding may not be more foothills, but it can not produce new plants from roots. Lowerers may root in species-typical ways, but never grow into fertile plants. Since the behavior is hardly predictable, you should try different methods of vegetative propagation in such varieties until one works.

Allow raspberries to multiply

If you've already gained some experience with raspberries, you've probably already landed at the old genetically modified raspberry varieties, or even the original wild raspberry.
The original wild raspberry always proliferates through root sprouts, the old cultivars do it of course after. In the past, people were happy when they came to new crops without having to grab their wallets; at the moment, the gardeners are rapidly increasing and find such a view reasonable as well.
If you cultivate old raspberry varieties or wild raspberries, you and your gardener ancestors should from the outset be careful to assign raspberries to a location where streaks should not disturb them for a while and simply grow up.
If you have found because of the raspberry flavor to the old varieties / wild raspberries, without thinking about streamer, that is not a broken leg. You can rip off or use the self-runners, even in a more suitable location. Then wait until the offshoot has developed its first own raspberry leaves above the earth, that's the sign that it has made enough own roots. The best time to move to a new place is also for these foothills of the fall.
If you have several varieties of raspberry in the garden, you may want to rearrange a variety that you did not want to multiply. Also, no breaking your leg, that could be eliminated again, but urges you to make a final decision about which raspberry may remain in your garden and end up in your dessert and in your jam.

And what about seeds?

Theoretically, raspberry plants also multiply by seeds, at least the raspberries that grow freely in the forest still do that, and the much more original genetic material in supporting (old) cultivars can usually do so as well. Propagation is not for impatient gardeners, true plant propagation, with adaptation of genes in the sense of evolution, etc. is compared to the rooting of a plant part a rather leisurely business. The young plant builds up from the ground up; It can take years until a handsome raspberry bush has developed and bears fruit to a noteworthy degree.

Shoots of a young raspberry

The result might surprise you, and not by "the one generation evolution". If you have raked freely fertilized raspberry seeds from the harvest, the insects could have "mixed in" all kinds of foreign raspberries during the pollination. So, whether the result will satisfy you depends on what kind of raspberries grow around you and how well the genes of these raspberries are understood or mixed with the genes of your raspberries. Always a delightful experiment, you just can not have any set expectations for its outcome.

Raspberries and plant variety protection

Plant variety protection is regulated by German law and European law, and if you have planted one of the new raspberry cultivars, plant variety protection may be governed by American law. In all these laws there are interpretable legal terms, for all sorts of constellations, the various courts have formed more or less determined opinions, international plant variety protection can be regulated by international treaties and / or dealer agreements - if you want to learn about plant variety protection, you need a lot Time and probably have to start from scratch when you're done, because something is constantly changing.
In some plant variety protection laws private cultivation is expressly excluded, according to some you would have to pay royalties for the rooting; according to the German Plant Variety Protection Act, you may even breed with protected varieties; Anyone who wants to claim plant variety rights must actively do so and prove that they are in fact safe in terms of plant variety protection as long as you have plants that are fully named Rubus idaeus' Annamaria ',' Elida® ',' Himbo-Top® ',' Malling Promise 'or' Pokusa ', just duplicate for your garden and do not intend to romp with the results of a brisk trade.
Raspberries with the name Rubus idaeus can multiply, breed and sell without interference; Rubus is the botanical name of the genus and idaeus the botanical name of the species raspberries. The species itself, the actual original original plant, can not be protected as a variety; in communities such as B. Free- Seeds.Org. e.V. (werden.freie-saaten.org) you can continue to inquire about the many old raspberry varieties that are not (anymore) subject to plant variety protection.

Limit raspberry multiplication

The more varieties of a plant species exist, the more difficult careful breeding work (which, of course, still exists) to delimit from breeding quick shots that only want to cash in on the extra profit from more expensive sale of the protected variety. The hobby gardener, on the other hand, has a good relationship with a passionate gardener and more and more often the simple touch to the original... for example with raspberries, when he is desperate for more than 1,000 varieties.
If this hobby gardener has previously collected the varieties with the best marketing names and hits the bull's eye for the wild raspberry, he could make a surprising experience: He gets to know the vigor of a plant, the millennia-long development on a specific environment was optimized and grows in this environment (the raspberries are among the native plants). Can be quite powerful, grow up within a radius of about two meters, with displacement of weaker plants.

Take seeds of raspberries

If the wild raspberry (or the old raspberry variety with a similar vigor) could not be moved to a location where it can spread a bit, you can "pin it down" in its place from the outset. The following methods can do this:
  • Plant the raspberries in row ("raspberry hedge") and place a root or rhizome barrier around them
  • It should go over the entire width of the root space of more than 1 m and is best introduced before planting
  • Retrofitting is possible, but a rather unpleasant Buddelei, even after already ausgeüxten roots
  • The roots of a raspberry can be "locked in" with bamboo rhizome barrier film, thick pond liner or special galvanized profiles
  • The recycling variant uses old roof tiles or path plates, the skilled home improvement pours a narrow concrete edge around the pitch
  • Disadvantage: Impermeable root barriers interrupt the moisture balance of the soil
  • If you do not take corrective action, the raspberry dries up in the next hot summer or the roots rot in the wet bath
  • Alternative: Place the raspberry plants in pots of at least 25 liters capacity (or in the good old mortar tubs)
  • Disadvantage: Raspberries in the bucket need frost protection in winter and the warmest place in the garden, eg. B. on a protective wall
  • Alternative no. 2: They regularly sting off to foolish foothills, then tear them out together with their roots
