I see a lot of info here about planting and caring for raspberries; and it is all very helpful...
There are raspberries in my grandfather's yard in Massachusetts and I will soon be moving into his home. It's not a large area (but they are trying to spread of course), maybe 10 ft x 10 ft originally. He had been unable to care for his yard for about the last 10 or 15 yrs; as he was 95 when he passed this last Dec. Meanwhile, I did notice they bore some fruit this summer although they seem past fruiting now (late July). My sister has been living there for a while, but I know she has not done anything to the plants at all. It is important to me to preserve these raspberries if possible...they are the last fruit bearing plants left on the land, which once had pear and apple trees!

If anyone would be so kind as to give me an idea of what I should be doing first and foremost to help these poor things along...I know I will have to prune out the dead stuff. Is it okay to do that in August or should I wait? I have no idea what variety they are; and I'm not close enough to look right now! Thanks!
