Part 55 (1/2)

Strawberries in this vicinity were badly injured by ice in winter where not covered. Ours were covered and now promise a good yield. Began picking the 14th inst.

We set quite a patch of everbearers No. 1017 this spring. They bore last fall but chickens picked most of the berries. Superb were unsatisfactory and winter-killed where not covered.

Carrie gooseberry has set full of berries and plants look fine.

All other trees and shrubbery in general at this station are in good condition.

All plants at this station went into the winter with favorable soil moisture conditions. Many plants, however, made a late growth and were still in growing condition late in September.

The winter was a long and severe one, although there was more snow than usual. The early spring was severe, being both windy, cold and dry. Up to date (June 9th) there have been very few calm days. Three or four very severe dust storms did considerable damage by blowing out seeds and blighting the tender new growth of many plants.

The winter of 1915-16 in this section can be called a test winter, as much winter-killing both in root and top has resulted.

A large proportion of the apple and plum orchard (60% to 75%) killed out. There was no mulch or protection in these orchards. Practically all grapes killed out, even though protected. A few Beta are alive at the crown. Asparagus (unprotected) suffered severely. All raspberries had been covered with dirt. They came through perfectly and promise a good crop.

Strawberries wintered successfully. The South Dakota variety came through perfectly, even when not mulched. All are in full bloom now.

Practically all of Prof. Hansen's plum hybrids killed out entirely, or are dead to trunk or crown.

A large number of seedlings of Chinese apricot, Chinese peach, native grapes, Juneberries and bullberries pa.s.sed through the winter with little or no injury. About 1,000 Beta seedlings, lined out as one year seedlings in the spring of 1915, winter-killed, with the exception of about seven or eight plants.

Paradise apple stocks wintered safely.

Soft maples that winter-killed to the ground in the preceding year are good to the tips this spring, even though they had made four to six feet of new growth last summer.

Many new plantings have been made this spring, especially along plant-breeding lines. Extensive experiments have also been started with fruit trees, shelter-belt trees, ornamental shrubs and perennial flowering plants to determine the factors that influence the hardiness of plants.

Strawberry No. 1017, from the Minnesota Fruit-Breeding Farm, made an excellent showing in 1915, and all plants bore some fruit. Only a few runners were made, however. All plants were potted in fall, so no data has been secured on their hardiness. Several hundred more plants of this variety were set out this spring and they made an excellent stand.

_Syringa j.a.ponica._--The j.a.panese tree lilac has often been recommended by this station, but last winter was unusually severe, and an old tree obtained from Prof. Budd, nearly thirty years ago, now shows several damaged branches. Younger trees on our grounds and in the city parks show no injury. Perhaps this tree cannot be expected to live to be much more than thirty years of age nor attain a much greater height than thirty feet. The old tree is throwing up new stems from its roots and may rejuvenate itself.

_Caragana._--The small shrubby caragana (Caragana pygmaea) was unusually fine this spring when in full bloom. We received it from Prof. Budd many years ago. It does finely in the clay banks of Lincoln Parkway in this city, but it is seldom offered by nurserymen. Caragana frutex, formerly called Caragana frutescens, is a somewhat taller shrub and not quite so floriferous. It makes a fine screen. Both of these shrubs are addicted to root sprouting, and might not please those who care for a stiff, formal garden. Both may be readily propagated from root cuttings.

_Roses._--Hansen's Tetonkeha rose at this writing is in full bloom and is a very striking object. It grows to the height of about four feet and needs no protection. The flowers are large and of a deep pink color. It seems to be as hardy as the old yellow rose of our gardens, that rose being now, too, at its best. Among other garden roses Paul Neyron is in a rather weak condition, Ulrich Brunner is doing a little better, while Mme. Georges Bruant is doing still better. Rosa pratincola grows on our grounds naturally, and we have brought in from the edges of the timber Rosa Engelmanni and Rosa Maximilliani. A friend in Duluth has sent us Rosa Sayi, and we obtained Rosa Macounii from the Bad Lands of North Dakota. These roses, as well as the more common Rosa blanda, make an interesting addition to the hardy border.

_Delphinium Formosum._--We obtained a plant or two of the old tall larkspur almost thirty years ago. The old plants persisted several years, and seedlings have grown up from self-sown seed, and the plantation is now as attractive as ever.
