How many days apricot blooms

The beauty of flowering apricot trees can last up to 10 days.

At what temperature does apricot blossom

Friendly flowering of apricots begins at a temperature above + 10C

Awakening of flower buds occurs already at an increase in temperature to + 50C. If it occurs briefly, then the kidneys freeze again. If the temperature persists for a long time, flowering begins. The sum of effective temperatures exceeding the threshold of + 50С, for the beginning of flowering of apricot should be equal to 3000С.

For flowering apricot trees need temperatures above + 100C. Ideally, this should be a temperature of + 17, + 190С in calm weather without strong winds. Such conditions are optimal for the fertilization process, and the bees are then most active. In reality, the temperature spread happens from +7 to + 280C. And as a result of this, the fruit yield will be unstable.

When Apricot Blossoms

In the south, flowering begins in the first half of April, in other areas a little later. Early flowering is dangerous consequences, since the threat of spring frost is likely. And the early development of flower buds leads to their death by return frosts.

Spring frosts are detrimental to flowering apricots

How to keep apricot blossoms in spring: recommended methods

Extending the dormant period of an apricot is a real way to increase the regularity of fruiting. There are many ways to do this. Experts believe that it is best to combine several of them at once:

  1. Vaccination on a crop with a later maturity;
  2. Summer pruning (the process is described in more detail below in the advice of gardeners);
  3. Mulching with sawdust: first sprinkle the tree trunk with snow, then with sawdust, and then again with snow, ramming each layer. Such a “pie” freezes in a single layer and does not melt for a long time, restraining the beginning of flowering;
  4. Whitewashing of the trunk: white color reflects the sun's rays and prevents the warming of the trunk;
  5. Spraying with saline: Before flowering, spray the crown with steep saline (400 g / 10 l of water). Flowering will shift by 7-10 days;
  6. Water spillage: in autumn, immediately before frosts, water a tree abundantly with water so that it freezes well in winter.

Expert Advice

You can delay flowering in only one way, but not by mulching and tamping the snow, that's for sure. It is necessary during summer sap flow, in our Lower Volga, this is the end of July - beginning of August, to make a small pruning of the tree. At this time, fruit buds are laid for the next year. Cutting out diseased and at the same time dry branches, you transfer this formation ten days later (until the tree becomes sick). Accordingly, the flowering of the next year occurs later.

How to protect blooming apricot from frost

From light frosts (up to -10С), smoke can be prevented from planting, because in this way a smoke cover is created around the trees, which does not allow warm air to rise and leave. It must be "laid" before the freezing and held until sunrise.

Blooming apricots will help save watering and spraying from freezing at -20 ° C:

  • Watering should be plentiful and carried out before freezing;
  • Spraying will have an effect when the temperature drops to minus indicators.

The most reliable shelter is shelter with any material: woven or non-woven.

A simple roof above the plant holds 3 degrees of frost, shelter to the ground - up to 5 degrees.

And here is such advice on preserving plantings from frost.

Making smoke bombs

This method of making smoke bombs - you need ammonium nitrate (ammonium nitrate), which is sold in a fertilizer store, and regular newspapers. First you need to prepare a solution of nitrate, proportion: 1 liter of water and 300g of nitrate. Simply put, you need to take a liter plastic bottle, fill it with 1/3 ammonium nitrate and completely fill it with water, you need to wait until the nitrate is completely dissolved. A foam will appear at the top, which must be carefully drained. After that, you need to insert a flower sprayer into the bottle. Now you need to take the first newspaper sheet and completely moisten it with a solution from the sprayer (be sure to place something under the newspaper, all this must be done away from walls, furniture, carpets, etc.) On top of the impregnated first sheet, apply the second and repeat the procedure. After all the sheets are wet with the solution, turn the resulting stack on the back side. They should dry completely at room temperature for 3 to 5 hours in a suspended state on a rope. 1 liter of the resulting solution is enough for about 35–40 newspaper sheets Newspapers cannot be left in direct sunlight (!) We will describe how to make a smoke bomb from these newspaper sheets. Gently bend the newspaper sheet soaked in solution, then bend again. We perform a similar procedure with all the sheets. We take one folded sheet, tightly twist it to the middle, put another into it and twist it further. When we reach the middle again, put another sheet, etc. Everything should be very tight (!) After twisting the last one, rewind the resulting product with adhesive tape and ram it from the ends. Chimney stuffing is ready! Attention! A checker, twisted from newspaper sheets, may catch fire during smoke emission (especially if you use it in the wind). To avoid this, it is necessary to make a housing. For this, a half-liter aluminum can is ideal. It is necessary to cut a cover from it from above, and then completely cut off the bottom. Insert the curled flue into it (if it hangs, wind it up a little with plain paper) so that it reaches the end. After that - cut off the excess metal so that 1 cm edges remain, carefully bend them. Smoke is ready to use! Application- Ignite it on the side and throw it away, puffs of white smoke will go. Freshly made newspaper smoke bombs burn with the release of a large amount of smoke, but if they are stored for a very long time, they may not be ignited at all. It is best to store them for no more than 1 month and store in plastic bags to protect against moisture. Try it - determine the number of checkers and the smoke time.
