April 20: Over 200 reports arrived over the weekend. The geographers and geoinformatics specialists from the rgeo team at the PH Heidelberg have now added these to the new apple blossom map.

–

April 19: Apple blossoms now in large parts of Germany +++ the northeast of Rostock and north of Hamburg are still free of apple blossoms +++ news currently from Pölitz near Bad Oldesloe, Nordheim vor der Rhön, Perleberg in Brandenburg +++ also from Balve im Sauerland and Trimbs on the Nette +++ in Mühlingen and Donaueschingen bloom over 600 meters +++ in Wessobrunn / Upper Bavaria at 725 meters +++ thanks for a message from Upper Austria: bloom in Ampflwang in the Hausruck valley at 560 meters +++

April 18 +++ more and more apple blossoms in the low mountain ranges +++ e.g. Rothaargebirge, Eifel, Weserbergland, Vogelsberg / Osthessisches Bergland +++ in Wilkau-Haßlau at the foot of the Ore Mountains 3 days until flowering +++ also in Rattenberg / Bavarian Forest +++ message from the Alps: apple blossoms in Bern / Switzerland +++ the later varieties bloom in the valleys of the southwest +++ first message from Bunde am Dollart (Ostfriesland) +++

The apple blossom was on the road for 28 days from Gundelfingen in Breisgau to Rostock on the Baltic Sea. In other words, the blooming zone has so far spread from the southwest to the northeast with a daily average of 26 kilometers. The long-term average is 40 kilometers per day – so we are currently experiencing a rather leisurely spring. When our new map was calculated, the Rostock message had not yet arrived – hence no green in the Rostock area.

–

April 17: Flowering reaches the Baltic Sea near Rostock +++ First blossom from there came today 12.52 p.m. +++ Blossoming apple trees in Berlin and the surrounding area +++ continued strong apple blossoming in the south, southwest and west. Partly in layers over 700 meters +++

–

April 16: Intensive apple blossoming in the south-west +++ blossom climbs approx. 30 meters higher in the low mountain ranges +++ Northeast must continue to wait for full spring +++ full blossom and the end of flowering can also be reported +++ new map shows the current state of affairs:

–

April 15: Albstadt, Swabian Jura, at 760 meters (!). A balcony apple tree is blooming there. Not representative of the field. But at least. +++ Another low mountain range: Mogendorf / Westerwald, full bloom at 290 meters, i.e. Start of flowering probably at 400 meters +++ Hochtaunus, Neu-Anspach, apple blossom at 350 meters +++ at the foot of the Alps in Bichl at 630 meters +++ But it can also go lower: In the northeast, flowering begins in Havelberg. 26 meters. +++

And after a week’s Easter break, the computer calculated this apple blossom map from a thick stack of messages:

–

April 14: First blossom photo from Dresden! Apple blossom reaches the Elbe valley. +++ Reports about apple blossoms also from the Leipzig region. +++ Does cold air slow the advancement of the bloom zone to the North Sea? +++ In the south and southwest, apple blossoms continue to climb into the low mountain ranges +++ Even in the river valleys, many late blooming varieties +++ The rgeo team in Heidelberg is currently calculating new apple blossom maps.

–

April 13: Reports, but still without a photo, from Wilhelmshaven and Hinte. Is apple blossom reaching the North Sea coast? +++ Very many reports from the entire southwest up to 500 meters +++ in Oberkochen / Swabian Alb almost open flower at 600 meters +++ Middle Rhine Mountains: Mendig / Eifel flower zone climbs to 310 meters +++ more and more apple blossoms in Lower Bavaria + ++ more and more apple blossoms in Westphalia and in the valley of the leash +++ pear blossom in Havelberg, ie soon apple blossom in the east +++

In the south, the apple blossom reaches an altitude of 400 meters. Expansion of the bloom zone from the Lower Rhine to the Münsterland has started. The apple blossom hotspot near Hanover is expanding to the east. Other rooms where something is happening are instantly circled in orange on our map ….

–

April 8: +++ apple blossom in Neu-Ulm shortly before the start +++ start of flowering in the Hanover area +++ open flowers in Erding near Munich +++

April 7: +++ first apple blossoms on Lake Constance +++ first blossoms in Aachen +++

April 6: Number of reports increases

Heat above 20 degrees is currently driving the flower development. Reports come mainly from the valleys of the Rhine and Neckar. But also the first flowers on the Moselle and Lahn. Here is the new card:

–

April 5: First apple blossom photo from Mainz. Furthermore…

… a first picture from Koblenz, from Bingen and also from the Lower Rhine! Apple blossom also reaches Kinheim-Kindel in the Moselle valley. Several apple blossom photos come from the Oberreingraben. In Berlin, on the other hand, only the first delicate green leaf tips on a balcony apple tree. In Igersheim / Tauberfranken: First green leaves on the tree, but very small, tightly closed flower buds. In a nutshell: apple blossom along the Rhine!

April 4: First photos of apple blossoms and ..

… balcony apple tree in Cologne has opened its flowers. Ornamental apple blossom in Rheinberg on the Lower Rhine. Flower photo from Arzdorf near Bonn unfortunately shows no apple blossom – but it could slowly be there.

April 3: Has the flower already reached Heilbronn?

We have not yet received any reports from the central Neckar region – but the apple blossom model calculation stiffly and firmly claims that the first apple blossoms should already be there. We look forward to seeing the next 48 hours. Report here!

–

April 1: The first map

The first apple blossom hotspot in Germany runs along the Upper Rhine. The pink areas are those areas in which the first opened apple blossoms could be found in the next 3 days. For the next card, please report trees here.

–

March 28: A warm day – but only one

Temperatures up to 20 degrees in the southwest. But tomorrow snow in medium locations. Rather not enough to trigger the first wave of apple blossoms.

March 25: Waiting for the flower tsunami

The cold nights slowed the flower development a little. So far, isolated trees are blooming in the Breisgau. And apple trees in pots, which are sheltered on the balcony or terrace, show isolated flowers. In a few days, however, the apple blossom should begin on large contiguous areas. Keep your eyes open and report the start of flowering here!

March 20: Today we received the first photo of an opened apple blossom.

This means that spring 2020 is the earliest in the list of apple blossom early years documented by the SWR since 2006 with regard to the very first flowering. Now it is important to determine when we can no longer only speak of individual flowering trees, but of the flowering of the trees on large, coherent areas. In order to be able to determine this time of extensive flowering, we need attentive flower observers who send us many reports. Let’s go!

–

Along the Rhine, many apple trees will soon look like the one that was photographed in Denzlingen im Breisgau. Typical for an apple tree: First it unfolds two leaflets, which then look like two mouse ears.

–

This is what the pommologists call this stage of flower development on the apple tree: the mouse ear stage. From this point on, depending on the weather, it will take two to three weeks before the first pink flowers open.

By the way, before the apple blossom begins, it’s the pears. The pear tree does not show mouse ears. But you can still compare animals: His first leaves are grouped like the tentacles of an octopus around the still small, unopened flower buds. The photo that was sent to us from St. Ottilien shows this very nicely.
