We start early in the season using a 21-7-7 soluble fertilizer with micronutrients (JR Peters Inc.) and switch to a higher potassium product later in the season when the plants are fruiting: 21-5-20. They are fertigated with these materials continually at a rate of 100 ppm N. We have also used small amounts of Osmocote before the season begins, but I am not sure that is beneficial. I would suggest watching the watering carefully as well; plants can deplete the water in the bags quickly, and water stress will also stunt plants.
Thanks for writing Glyn. In our short-season, cold climate, Polka, Kweli, and Imara have worked well. We described these and some other cultivars in another video: ua-cam.com/video/x7ysAAr5S0U/v-deo.html You might investigate what others in your climate and region have had success with. Our work indicates that relative productivity and fruit quality of cultivars tends to be similar in the open field as in tunnels in bags. I don’t know of any cultivars that are particularly more suited to pot culture. I think later primocane fruiting types would do better in a long Mediterranean climate. Later types also tend to produce taller primocanes that are better suited for fruiting as floricanes during the subsequent summer, if that is your goal. In contrast, the early primocane fruiting ‘Polka’ does fairly well for us here because our fall harvest season is short, but it grows shorter canes and is not so well suited for floricane production. Some problems increased by the high heat and humidity in tunnels are powdery mildew and doubling of fruit, so cultivars prone to those may not be the best choices. I hope this helps. I will be interested to know which cultivars do best for you. Eric Hanson
I also like raspberries :)
Anyone doing this on a larger scale?
When do you recommend covering them for the winter?
Joan J, right? very nice grow!
Hi! Which tree bark did you use?
hi...the tunnel is 24xby...what...thanks
You need hay for winter.
Can you tell me what fertilizer regime you use? My raspberries in containers only get 2’-3’ high

What EC/pH do you need?
Any recommendations on the nutrients?
5.5 to 6.5
"several lbs per plant" is extremely vague ..
Can you recommend a cultivar that does well in high temperatures from your study. I want to grow in Med....so a challenge!!

THIS SHOULD NOT ONLY BE DONE TO MAKE MONEY..... STUPID!!!
