Recently my favorite hardware store has been selling pint boxes filled with large, beautiful black raspberries. I'm a buyer because my wife just loves black raspberries. Personally, after chewing the half million or so seeds each berry contains, I believe that the hardware store is the perfect place to sell raspberries.
In all honesty, I have never grown raspberries. I thought about it but they, especially the black ones, seem to have the reputation of a problem child. The chief issue is virus for which there is no cure. There are some cautions to take. Even then, five to seven years may be a stretch for the productive life of black raspberries.
When selecting plants, buy virus-indexed plants. They are usually grown by tissue culture, which harvests the few cells at the growing tip before they can be infected. Do not get roots from the neighbor's garden because the virus is almost certainly present in them already.
Second, do not plant in the vicinity of wild, fencerow raspberries or in the garden near where tomatoes, eggplants and the like have been grown.
Black raspberries fruit on second year wood. Each plant should be limited to five or six canes and the cane should be removed after it has fruited. Consult the Internet or the Penn State Extension Service for more complete information.
Red raspberries are a different game and quite a bit easier.
Blueberries are also available about this time of the year. The chief problem with blueberries is to get our lime rich, high pH soil to the low pH range blueberries need to thrive. Acid fertilizers, sawdust and sulfur are near the top of most lists to drive pH lower.
Other than that, blueberries are easy. When I grew them commercially they were seldom sprayed, which adds to their desirability.
Pruning in late winter is also rather straightforward. Each plant should have five to seven stems. Each year remove the worst (oldest) stem and let the best, new ones in place.
My strawberry patch was ok this year but did not set any world records. My chief problems were the damp conditions and a row that had become rather wide and thick. I did not spray.
An insecticide about bloom time is helpful especially if you are attempting to grow strawberries near a wooded area. The problem is a clipping insect that over-winters in wooded areas and can cut off a significant number of flowers.
Fungicides can reduce rot, especially in cool, damp springs like we had this year.
In general, my opinion is that spraying is optional with strawberries and our other berry fruits. On the other hand, I am a long way from believing that we can produce tree fruits in this climate without some spraying.
Now that the strawberries are over, the patch should be renovated. My approach starts with finding a high setting on the lawn mower and removing the leaves. I emphasize high enough as to not damage the crowns. Next I will use the rototiller to narrow the rows to eight to 12 inches. That will look like devastation, but spring bearing strawberries are quite vigorous.
Renovation is also the best time to fertilize. Do not fertilize in the spring as that just grows leaves. Now produces buds for next year's fruit. Attention to weeds now and all season is important. I used a light winter mulch of straw or corn fodder when I was growing strawberries commercially.
That's a quick overview of our most popular berries. Buying raspberries has a redeeming value to me. My wife likes them with vanilla pudding. I get a dish of vanilla pudding without the raspberries, of course.
