Hi Eric .
Of course I will explain to you why the Sweetheart cherry variety is a “disgusting” cherry variety.
Description of the variety Sweetheart
-
1st: Structurally, it is a variety with a strong tendency to branch (emit excessive lateral branches from the main branches, which are the fruiting branches)
-
2nd: Sweetheart, is a self-fertile variety with a tremendous tendency to overload fruits
-
3rd: Sweetheart is a variety whith medium naturally fruit caliber (27-29 mm. )
Consequences of this bad behavior of the Sweetheart variety:
Due to its tendency to emit a lot of lateral branches and overload the harvest, when the time of harvest comes, the cherries will be harvested like chickpeas (literally).
One way to solve this problem is to carry out drastic pruning, with the consequent over-work and this increases the caliber of fruit, but tremendously reduces the volume of the harvest, making it uninteresting.
Real solutions:
Since Sweetheart has a ripening date:
- 36 days later Burlat (reference variety in Europe)
- 17 days after Bing (reference variety in the United States)
And since Royal Helen (one of the best late-ripening cherry varieties), ripens only 5 days before Sweetheart, the solution is very simple.
For a professional, 5 days difference in ripening dates is an important period, but 5 days for an amateur is insignificant.
Obviously I have mentioned the Royal Helen variety, because it is a fantastic late-ripening variety, easy to obtain for you , and I omit to talk about the good ultra-late-ripening German varieties such as:
- Cerasina Final 12.1
- Kir Rosso
Because I know perfectly well that they are varieties that are impossible for you to obtain.
Really listen to me and if you have to put a late cherry tree in your orchard, choose Royal Helen and avoid Sweetheart.
The cherry tree varieties, with a strong tendency to harvest overload, such as:
- Nimba
- Frisco
- Sweetheart
- Black Star
Etc…
They are only recommended for professionals in the sector (they know perfectly well the production pruning of the cherry tree, and use fruit fattening treatments with hormonal biostimulants ), or for amateurs with extensive knowledge about the cultivation of this type of varieties.
Best regards
Jose
