ОглавлениеThe currant is essentially a northern fruit, therefore does well in Minnesota.
I plant my currants on a clay loam as it retains moisture and coolness, which the currant prefers. Their roots run somewhat shallow, and hence sandy or friable soils are not desirable. Soils such as will prevent a stagnant condition during heavy rainfalls are essential. I plant my currants early in spring as soon as the frost leaves the ground and a proper preparation can be secured. I plant them five by five feet apart, as they require a thorough cultivation the first two years from planting.
I plant mangels between the rows the first year; second year continued cultivation is practiced; third year I apply a mulch consisting of mushroom manure to a depth of from four to six inches, which answers a double purpose, to keep out weeds and to act as mulch at the same time. During a prolonged dry spell the soil is moist under this covering, and it makes it more pleasant for the picking, as it prevents the berries getting soiled after a rain during the picking season. You cannot fertilize the currant too abundantly, as it is a gross feeder and requires plenty of manure to get best results, as such fruit commands the best price on the market.
I planted my currants on ground previously well fertilized with well decayed barnyard manure.
I prefer strong well rooted two-year-old plants. The long straggling roots are shortened, and bruised portions cut off with a sharp knife. The tops are somewhat reduced, depending on the size of plants. I set them in a furrow, sufficiently deep to admit the roots to spread out in a natural position, fill in with surface soil and pack around the roots, so that when the earth is firmly settled the roots will not protrude out any place.
In regard to pruning I find the best and largest fruit is produced on canes not over four years old, and if judicious cutting out of the old canes is followed nice, large, full clusters of fruit of excellent character will be obtained. This is a fact that I want to emphasize: if the market is glutted with currants, you can readily dispose of your product, providing they are qualified as extra large, which results can be attained by following these rules.
Pertaining to insects and diseases, I spray my currants twice for the currant worm with arsenate of lead at the rate of two pounds to fifty gallons of water.
I also use hellebore (dry powdered form), especially valuable in destroying the worms when berries are almost ready for market, and on which it is dangerous to use arsenical poisons. I never was troubled with the currant worm cane borer. I attribute the absence of this dreaded insect to my keeping all old wood cut out, which is generally infested with it.
As to varieties I planted the following: Wilder, Victoria, Prince Albert, Red Cross, Diploma and White Grape. The Wilder is the best commercial berry, very productive and large, while the Diploma is one of the largest fruited varieties in existence, its main drawback consisting of a straggling habit of growth which requires either tying up the branches or pruning back somewhat short.
The Prince Albert is late and can be recommended for commercial use. Victoria is a prolific bearer, fair size fruit and requires little pruning. Red Cross is large fruited, but shy bearer. The White Grape meets with little demand as a market berry, fine to eat out of hand and an excellent table berry.
I also planted a few Black Champion; have not grown it long enough to know definite results.
The demand for black currants is limited, but the prices are fair. As to picking would say we pick them when not quite ripe, as the average housewife claims they jell better than when over-ripe. They must be picked by the stem and not stripped off—all defective, over-ripe and bruised berries should be eliminated at the picking.
When the box is being filled a few gentle raps should be given to settle the clusters into place, as they shake down considerably. All the conveniences and same character of boxes and crates used in handling of other small fruits are equally adapted to the currant.
Welcome the Thrushes—These Birds do the Farmer Little Harm and Much Good.—That thrushes—the group of birds in which are included robins and bluebirds—do a great deal of good and very little harm to agriculture is the conclusion reached by investigators of the United States Department of Agriculture who have carefully studied the food habits of these birds. Altogether there are within the limits of the United States eleven species of thrushes, five of which are commonly known as robins and bluebirds. The other six include the Townsend solitaire, the wood, the veery, the gray-cheek, the olive-back, and the hermit thrushes.—U. S. Dept. of Agri.
