Characteristics

• Timiryazev's memory begins to bear fruit rather quickly after planting. This happens for 3-4 years;
• flowering begins in the second decade of May;
• fruit ripening occurs at the end of August - beginning of September, in terms of timing, the variety belongs to the middle late;
• the yield is above average. Over the past 16 years, this figure has been 9 kg per tree. According to other sources, one plum in fruitful years brings up to 35 kg of fruit;

• fruiting is periodic, but not abrupt. Over 16 years of observation, 5 crop failures were noted;
• the plant has good immunity, it is weakly affected by clasterosporium and fruit rot, only by 0 - 1.5 points;
• the variety is not so resistant to pests, the defeat is estimated at 2.5 - 3 points. Mites are especially dangerous, they can greatly harm the tree;

• drought resistance in plum is moderate;
• the transportability of the fruits is at a high level, keeping quality is also good;
• the way of using fruits is universal. They are useful in their natural form, from which you can cook jam, jam, jam.
