The first grape berries rise

With the beginning of June the first grape berries rise.

The vine is subject to attack by many pests or diseases which must be protected specially in the vegetative cycle.

Weather conditions greatly influence the mode and intensity of the attack, but the conduct of the vineyard, its sanity, the quality of prevention and caste whose resistance to diseases and pests can be very different from each other, also determine the severity of the occurrence.

The primary treatment phase takes place in a relatively short period of time: from the cotton bud till the closure curl, i.e. the first 3 months of vegetative cycle. The long, hot and dry Summer, main characteristics of the Mediterranean climate, usually does not require treatment between the close of the berry and the painter (the moment when the berries come color), and from then to the proximity of harvest limits the application of most treatments.

Preparing potatoes for seed

Potatoes are tubers developed after sown mature potatoes.They're called stem tubers because tops or sides of the tuber produce shoots that grow into typical stems and leaves and the under sides produce roots. If the mature potato produces with more than one shoot it can be separated into pieces, each piece may be able to give rise to a new plant. The mature potato is used as storage for starches, proteins, and other nutrients by the plant. These nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter. This is a process known as vegetative reproduction and is used by farmers and gardeners to propagate certain plants. The mature potatoes are first prepared before going under soil. They're placed in dry and light environment to germinate previously. After germinate the ones which have more then two shoots and they're big enough are separated. The reason why it's better they have to be big to be separated is because they have to handle some cold when they're seed at the end of winter.
