Growing Raspberry From Seed

10 years ago

Hi...i'm wondering if there are any Professionals here that grow plants for a living I.E., Botany , Horticulturist or maybe you have a nursery and sell plants etc.

I have some rare Raspberry seeds from the " Fengmenhong" Jilin Giant Red Raspberry from China that i wish to grow in my backyard and so far i've been unlucky in starting a plant from seed as they are very difficult Raspberries to start from seed and these seeds are the only plant material i can get for this species, so maybe someone is interested in a project to help propagate this Rare Giant Chinese Everbearing Raspberry in which it may help someone else as well as me i'm sure the result will be worth it from what i have researched.

thanx

I've never heard the dry thing before. I'm no pro, but I've grown dozens of raspberry plants from seeds in the past from store bought fruit. You won't get the same thing, often times they're just sweet and no tart.

I usually pick a few berries and leave them somewhere warm for a day or two, then run them with my finger using a fine steel sieve and wash them thoroughly and allow them to dry in folded paper towels. When I'm ready I wet and wring out a paper towel or two, place the dried pods which have been ziplocked for a few months, onto one side then fold over the other side. I stick them in a baggy and put them on the condiment shelf in the fridge for about a month, then plant them. I've gotten about an 85% germination rate doing this. Raspberries are invasive, much like mint, so you'll need to check them out often as they mature. I planted and grew a little over 15 plants when I was 10, I'm 24 now and my folks' house's backyard now has about 60 different berry plants all throughout. They're regularly pruned now though, so they don't take up much space.

You could also do as nature intended, just throw a few berries into a pot or the ground where the soil is nice and rich, let it rot in the soil and come some time later, you'll have plants growing.

Depending on soil conditions and regional weather, you may have to wait more than a few years or more for fruit. If you're in California, fruit from seed usually results in faster mature times for trees. In the nearly 30 years my parents have owned that house, they've never had any luck with grafted trees. So they just did it like in the old country, they just planted what they bought at the store. Of the apple seeds, only two trees resulted in tart little apples, the rest of them are some type of cultivar, whether they're discovered or not is a mystery to me. One tree in particular sets crimson red apples the size of a fist with a buttery yellow, pink tinged flesh. The others are some type of gala and golden delicious variety, but not exactly those.

Those all fruited in 3-5 years.

Hi Greenhorn,

Raspberry seeds don't like to be dried and stored. Also, there are a few embryonic "keys" you have to unlock. Lot's of people have different favorite ways of doing this. I would do it this way. Pick ripe fruit and freeze it for 2 months. Thaw and let it overipen to the point of fermentation. Place the fruit in a wire mesh strainer, and separate the seed from the pulp. Place the seeds immediately into a cup of water that is 100F or so and soak for an hour. Place seeds in sterile soil and keep moist, maintaining a soil temp of 75F to 85F until you see signs of sprouting. Then, you can back off to 65F to 75F Here is a scholarly link on it (good luck with trying to scarify a raspberry seed!). You could also soak them in various acid solutions at point of planting. It's all in the article in the link below.

hi glenn never got my money back, they said they changed colour because i let them fruit on there first season, i still have a laugh about that, even the rubus research in the uk told them that this was impossible!! treasured plants is seasonal, only trouble is the advertise very late and supply bareroot, so hit and miss if the plants take in time, the golden everest i grow outside fill a row very quickly, has thick sturdy canes sometimes thicker than my fingers, and up to 6ft canes,a summer floricane, doesnt suffer mould ( like fall gold, golden queen, over here, berries are good size ,well formed, double the size of golden queen and bigger than fall gold, taste is good aswell, i grow the anne in my polytunnel for safety ( dont wanna lose her) and find it very very good, but not quite as good as golden everest,and crop a little less, i found noursefarms for the 1st time the other day, amazing plants but think only ship to the u.s. , i also do a bit of experimenting, and have grown an orange raspberry if anyones intrested email me, as i dont know how to post pics on the forum yet, regards stew

I get a lot of blackberry seedlings from fallen berries. All I do is rake the ground occasionally while clearing fallen leaves. Seedlings sprout up in Oct, Nov, then again starting in April. So I would say scatter on loose soil and rake lightly.

What type of raspberry is harmony and how do I grow the seed
Q

Hmmm...well, I have not heard of that variety either but that doesn't mean it doesn't exist. As mentioned above, raspberries are generally asexually propagated by using the roots or part of the canes from another raspberry. When they produce seeds, sexually, the offspring plants may have characteristics from both the parents, like humans. In nature, raspberries are eaten by birds or animals and during the digestion process, the stomach acid eats aways some of the hard coating on the outside of the seed (e.g. scarifying). After the seeds pass through the bird or animal they are deposited and experience the change in seasons, which satisfies the second requirement for chill hours (stratification). After these two steps, the seeds are ready to grow when warm weather arrives. You can simulate these steps by soaking the seeds in acid or scraping away some of the outside coating of the seed and then putting them in a moist paper towel in the refrigerator for 2-3 months.

Carrot seeds sprouted, first time growing from seed!

Ashley: Carrots are notoriously slow to germinate. I plant them in my garden each year. It can take up to 15 days before they are up and visible. Be patient when growing carrots. I also find they are real slow growing for me once they do germinate for the first 1/2 of the season. I often wonder if they are going to amount to anything, then they always surprise me with how much root and shoot growth I get in August/September when they start sizing up nicely. Everything I planted in my garden in late may is growing well, big and looking good except my carrots. They just sit there for weeks on end and now are just starting to get some height. I know by Late September they will be good for harvest. I think eating carrots fresh picked are truly amazing in flavor. While they do store well for me in the refrigerator, nothing beats eating them very shortly after picking. Such a nice intense carrot flavor.

Regarding that apple comment as I am interested in starting an orchard (hopefully) some trees can even be more than one type even if started from a red delicious seed for example. Not even the growers really know but they can set a new branch that might be gala, fuji or red delicious lol. Also UOA says now that chill hours are way off give or take hundreds of hours.

Mixed apple trees are invariably grafted scions onto a specific root stock. My horticulture teacher proudly displayed a 'family tree' with 17 varieties of apple grafted onto a stump of rootstock using various side, saddle and cleft grafts. True, the odd branch could possibly 'sport' but you could not claim any named variety as coming true from seed so it is not really the case that a Gala apple could sport to a 'Red Delicious'.

Yes, apples can, and are, grown from seeds...but the reason for using specific rootstocks, to determine size, allow for soil conditions such as ph, and longevity and vigour, not to mention maintaining clonal purity, vastly over-rides the tricky and unpredictable seed sowing methods, to my mind. I have had very little luck in growing out hardwood cuttings on their own roots (unlike roses, say) either.

The hardening off of seed coatings can definitely affect dormancy - many primula for example, will only go into dormancy when dried...in which case they will need specific stratification to break dormancy. The words 'double dormancy' can strike terror into the heart of any grower but it can usually be broken (the worst are the seeds which have only a few days of viability). Styrax, for example, requires various cycles of cool damp stratification, followed by warmth and so on. Either try Plant Whisper's method or check out the Deno or Clothier germination tables as even DD can be overcome.

Yes it is actually the case. Unexplained but fact sorry.

Jennifer, perhaps you can give us some links to this research? I'm having trouble understanding your statement that 'some trees can even be more than one type even if started from a red delicious seed for example.' Are you perhaps referring to 'sporting'? But as Campanula said, sporting would not produce a named cultivar.

Yes and give me a few days and no not sporting but an actual cane. Now you could argue like they say in radishes that inherent genetic variations exist but I understood it not to be the case. FYI Arizona is still so hot (90s in October is to much for me).

I am curious as to your definition of sports - an 'actual cane' would be either a limb mutation or a spur mutation which arises spontaneously - a sport in other words...and requires vegetative propagation to ensure the variety remains stable. This mutation or sport would be an entirely new variation on the scion tree and not a variety already in named cultivation. There is simply no way a 'Golden Delicious' will produce an entire branch of 'Fuji' say - none at all...but it most certainly could produce a cane which has similarities to another known breed.
