Östlonings hazel culture

Here in Southern Dalarna, we have had the worst hazel year long. Not even in the great old stocks, there were more than a handful of nuts to find. And so we go to Medelpad and find hundreds of hazel bushes, Most dotted with nuts. How can it be that?

Of course it does already mentioned mikroklimatet stor roll. To sum it all: If I had to choose the perfect micro-climate, it would be here. The distance between the highest and lowest point of Ove's garden is about 500 m and the height difference is almost 100 m. This allows the cold air has plenty of space to drain away from the upper parts of the garden. Thanks to the deep valley which can devour huge amounts of cold air occurs on the first night frost unusually late this land, often only the beginning of October.

The long, steep southern slopes toward Indalsälven is the prerequisite for growing sensitive plants in this latitude.

Hasslarna thrive therefore best in the upper reaches of the garden, while they do not give fruit in the very lowest parts of the chips. They get both much sunlight and does not suffer from the cold air that can mean trouble in the fall. In addition, the area is quite poor rainfall, with as little as 500 mm rainfall per year and at least 1700 hours of sunshine, which means that the heat summation that the plants will absorb the growing season is relatively high. Despite the small rainfall, there are plenty of mobile soil water, which hazel bushes and trees nötbärande love, again thanks to the long slopes that drain the mountains that are above the garden.

Although it has been a cold spring are hazelnut harvest in Ove garden as big as usual,.

In addition to micro-climate it is also hasslarnas origin, tai arising, which is an important factor contributing to their productivity and härdiget. Ove gathered nuts and plants from all hazel occurrences in California, he found, among other things, with the help of the amazing book "The hazel in Sweden. Yore and now"Which was written by Gunnar Andersson by year of publication 1902. All of these are so-called reliktbestånd from previous warm periods, t.ex. during the Neolithic period around 4000 f.Kr. growing in the hot southern slopes, Please against the rock walls. We visited one such stock on Hatt Hill, near Sillre. The bushes may have been there 6000 year and could not feel anything but reverence when we had coffee, among those bushes whose ancestors once grew at the Baltic Sea beach.

What is unique about these reliktpopulationer is that they have their own species that flower very late, namely until the end of April, when southern provenances already has blossomed over a long time ago. This reduces the risk of unsuccessful fertilization considerably, which is otherwise a major problem for hazelnut cultivation in almost the entire country.

Hasslarna has been crossed with each other and the countless seedlings is all junctions of the country is probably the hardiest shrubs. The breadth of the genetic material that Ove has collected in his garden becomes clear when one compares the various nuts with each other. They differ quite a bit in appearance, shape and size and it would certainly be worthwhile to make a systematic inventory of the best mother plants in Ove garden and begin to multiply them vegetatively to produce high-yielding hazel bushes of northern latitudes. To my great joy shared Ove generously of both nuts and seedlings and the first Östloningshasseln are already planted in the Putt Myra forest garden.

The variation between the hazelnuts from Ove chips are pretty big as this picture shows.
