The calendar, addressed to amateur gardeners, lists by month the main work that needs to be done in the garden, vegetable garden, and flower garden throughout the year. But the weather, as you know, is a capricious lady, and for example, the onset of spring may shift two weeks earlier or later relative to the calendar date, so the deadlines for completing these works are indicated approximately. It is also important to take into account the difference in the timing of plant development in the south and north. Thus, the beginning of sap flow in plants in the south occurs, on average, a month and a half earlier than in the north, so you should not literally follow the calendar; it is much more important to carefully monitor the condition of the plants in your area and, taking into account local weather conditions, carry out the work recommended in the calendar on time.
