General work, pruning, grafting
The routine maintenance of the plots of land continues: if they are grassy, at least one cut per month must be made, distributing the flakes evenly. Crops such as olives or hazelnuts require free soil, but clean and permeable: let’s make sure that the surface has not been compacted and in case we perform a milling.
In the southern regions and on the coasts, it is time for citrus fruit to ripen: if we want, we can intervene with special growth regulating hormones: the harvest will be more scalar and conservable.
It’s a good time to prepare the plots for new installations: let’s not just create the holes, but work well in advance on the whole area and include plenty of mature manure.
It is possible to carry out maintenance pruning, rejuvenation and training: the plants will have until spring to recover. We work on stone fruit, cherry, actinidia and even citrus.
Dormant bud grafts are successful on stone fruits and pome fruits.
Irrigation and fertilization
In this month, irrigation is no longer urgent: temperatures are lower and rainfall is more frequent. Moreover, it is superfluous, if not harmful, to distribute water to those plants that have already completed their maturation: we will cause unnecessary vegetative growth. Let’s irrigate only the fruit trees that have yet to complete their cycle, in case of prolonged drought and high temperatures.
Usually this practice is required by citrus fruits and small fruits that have a second autumn production.
Fertilisation is not yet necessary, but it is essential to monitor fruit trees sensitive to iron deficiency: if we notice the symptoms we distribute chelates at the root level and, for a more immediate effect, through foliar nebulisation.
Orchard care in September: Parasites and diseases
In order to combat pathogens in time, it is very important to monitor our trees regularly: we recommend to do so in conjunction with the harvest and in the days following the major weather events. We promptly remove damaged fruits and if we notice the appearance of cryptogams on the leaves we intervene as soon as possible with curative products.
For pome fruit, we pay attention to the fire blight: in many regions it is mandatory to quickly kill or destroy the affected parts in order to block the spread.
It is a period propitious to the spread of parasites of various types: we can control them with pyrethrum, Bacillus Thuringiensis or spinosad. For cochineal and red spider mite we opt for white oil.
For cryptogams it is good to prevent with the periodic distribution of copper, to be repeated after the rains; for the peach tree in vegetation (especially for the bubble) we opt for other products, given the phytotoxicity.
