I would like some tips on how to grow healthy red raspberries and how to divide them and when.
Here is a link for a page that lists a series of articles - all about raspberries. I think you'll find answers to your questions here: https://www.gardeningknowhow.com/search?q=raspberries
I bought 4 plants last year from a nursery as primocanes, and planted them in a new bed. They produced a few tiny berries last year that turned brown and dried up. This year 3 plants were eaten (to the ground) by rabbits. The one that is left is a floricane and is producing tiny berries that turn brown and dry up. The upper leaves turn yellow and brown, get holes in them and fall off. The stem looks healthy but there are brown nodules where leaf stems meet the main stem. I am not sure if that is normal. Thinking it might be a fungus, I removed large suckers that were nearby to increase air circulation and have stopped watering frequently, and I pulled out the many wild raspberries on our rural property. It still has the same issues.
It does sound like a fungal infection. This will need to be cured before planting again. These articles will help:
I have a three year old red raspberry bush that has never been pruned. I have read that the best time to prune them is after they have produced fruit. We're way past that now ...should I cut the whole bush back to the ground and start over in the spring and then follow instructions or will that kill the bush. Its getting very overgrown and did not produce good berries this year. Thanks for your help.
Here are pruning instructions. It helps to know if they are everbearing, summer bearing, or fall bearing:
Hello, you don't list Dorman Red Raspberry as being good for Zone 9? We have grown it several times here in Zone 9 (Houston, Texas area) with good success. Any reason why you don't list it? Just asking, not trying to be offensive or anything. Just trying to find us a good red raspberry. I planted 6 Caroline Reds, in summer heat 3 months ago but only have 2 left. I have tried a couple other red raspberry plant that have since died. It is probably critical that I plant them any time except Summer.
I notice it is listed in the zone 8 gardening article; perhaps it was listed as only hardy to zone 8. A Texas extension article says raspberries don't grow well in Texas conditions, so that is probably why you have so much trouble. Have you tried calling your local Extension agent to see which raspberry varieties grow well in your area?
