In the rural wooded area in which I live the wild blackberries are rampant and are impossible to eradicate. So, yes, I will most likely lose production over time. Most of the growers that are more isolated from the wild berries do really well with their crops year after year but I did start having problems last year with the cool wet year we had.
@alan I can very well relate to your love story relating to the brambles and later occurring tree fruit. We have planted many trees but as of yet only seen a few pears and jujubes produced. It will be a few years before good production of those and in the search for quick home grown fruit the berries fit that bill. We do have figs but have had them for years and I guess, kinda take that fruit for granted. . And yes, those berries got pretty labor intensive. I sure did enjoy them this last year though as a much easier gathering than searching out the wild ones and everything that that experience offers!
@BambooMan Oh, yes, Dewberries! They are so much better to me than blackberries and when picking wild we sought the dewberries out first. I did see some of those offered for sale the other day and I am sorely tempted to order! Not many people I know today know the difference.
