Yes, I did notice your tractor in the background there. Hopefully the parts come in soon and you can get those repairs. I just completed my annual oil change and fuel filter change last Sunday on the property. I made a big mistake when changing the fuel filter. I just changed it like I would a car (gasoline engine fuel filter). Boy was that stupid with a diesel engine. The tractor fired right up and than mysteriously died. After a quick research on the internet (What would we ever do without it these days?!!) I found that I had air in the fuel lines. After about two hours of bleeding fuel lines, fuel injector lines, refilling fuel filter bottle, trying to restart over and over each time.....it finally came back to life. Geez that was some serious frustration.
My Northerns have been a big disappointment. All 4 of my Bluerays did so poorly I pulled them and replaced them. 2 of the 4 Bluecrops I planted are left and they are doing fair at best. (I will try to send you a pic of those in there 3rd year) this weekend.
The SHB have tasted the best and are doing good. (Ozark, Summit and Blue Suede). I have 4 SHB Oneals as well in there 2nd year. They have struggled so far.
The Rabbiteyes are doing fantastic. I am 8 for 8 with them. All 8 (4-Climax and 4-Premier) are growing extremely well. There height is about eye level with me now in there 3rd year and they have a ton of fruit this year. I am hoping for better taste this year. Kinda bland on 2nd year small crop last year. Hopefully the taste gets dialed in as they age.
For fertilizer I have only used Organic hollytone and mostly cottonseed meal. Nothing synthetic. Something you may consider based on the age of your blues. Blues can burn in a heartbeat if not careful with synthetic fertilizer. With organic fertilizer that risk, especially in there most vulnerable early years is virtually zero. Its risk versus reward for me kind of mentality. Too each his own.
