Ecological Requirements of Almond

Climate conditions
Almond is almost resistant to winter as peach.It grows on the Taurus mountains without damage at an altitude of 1050 m.However,the most important factor of limiting cultivation of almonds is the late frosts in the spring. Almonds bloom before many other fruit species.Therefore, where there are continuous late spring frosts, it is not possible to get stable almond product.
Buds of flower before blooming are short-resistant to -4.4 ° C, and when the petals start to fall, the degree of resistance is -2.2 ° C, while small fruits are damaged to -1, -0.6 ° C.
It is desirable to establish a garden of almonds in which late spring frosts are effective, and take into account of the following:
a) Choosing a direction that will provide late awakening,
b) Establishing gardens on the slopes where cold air flows,
c) Selection of late floral and long-lasting varieties,
d) Undertaking the necessary technical and cultural measures against frost.
Mature fruit of almonds occurs in 6-8 months of flowering.This long period also requires a high BDST (Total Growth Stages and Hours). In places where the temperature is not high enough in the summer months, economic cultivation can not be done.

Land conditions
The almond tree is not selective for the soil. The tree grows well in dry, stony,gravel and lime soils where other fruit trees can not survive. However, it needs deep soil. In such places the roots can go deeper than four meters. However, the almond gives the best results in sandy soil. Almond does not like excessive moisture in the soil and volatility of groundwater. Sand, gravel, dry soil should be supported by organic materials. Like peach, almond also requires nitrogen. In a land where there is no nutrients, the trees can not develop well, the fruit relationship is low, and the interior can not be shaped well, so it does not fill its corn and it becomes wrinkled.
