Answer: Unproductive plum tree

Dear Walter,
your plum plant has a long history, as these plums have been grown in Europe for centuries, they are green plums, even when ripe, very sweet and juicy, among the first to ripen in the garden, very difficult to find on the market. For all these reasons, before cutting the plant to the base to eliminate it, I would give it a few years to start producing fruit.
First of all, it is a plant that generally develops well even in half-shade conditions, so the position in which it is located should be perfect for the health of your sapling, and therefore it should develop without problems and bear fruit.
Then, generally these plums fructify better if the flowering season is characterized by a good amount of rain; if this were not the case, you can stimulate fruit setting by watering the plant when the soil is dry; a good manure-based fertilizer at the end of winter certainly does not hurt.
That said, I remind you that the plums only bear fruit on the brindilli, which would be the short sprigs of a year, produced the year before flowering, especially with regard to the queen Claudia plums; therefore it is advisable to stimulate the plant with pruning to favor the development of brindilli.
It often happens that the specimens of Queen Claudia not pruned, or pruned badly, tend to develop a couple of well vigorous branches, which have few or no brindlils, but many leaf buds; therefore it often happens that these plants produce few fruits.
For this reason it is advisable to prune the plant in the best way, at least in the first years of development, so as to favor the development of a balanced crown, made up of branches of leaves and a good number of toasts.
At the end of winter, we first of all intervene by widening the foliage, pruning the ruined branches and those that develop towards the center of the tree, then we cut the shorter and thin branches slightly; if your tree forms only one or a few vigorous branches, full of leaves but without fruit, it is advisable to practice the so-called return pruning, or rather it is good to shorten the longer and more vigorous branches (especially if devoid of toasts, and therefore of fruits) , cutting just above a branch that develops laterally. µIn this way the renewal of the crown of your sapling is encouraged, with the consequent production of new branches. Since the queen Claudia plum bears fruit on the brindilli, which as mentioned before are one-year-old branches, that is to say they were produced the year before the fruit was produced, it is likely that despite the pruning, your small plant begins producing many fruits starting from next year, or from the next; of course, rather than waiting for the fruits of a new plant, planted this year, you should prune the plant you already have, and wait until next year.
