Vine-growers and tractor drivers work all year round on the 600,000 vine-plants (about 10,000 per hectare) of Château Latour.

A year at Château Latour takes place as follows :

- Pruning from November to March. Only two branches are left ("guyot double" pruning system), and three buds on average on each branch;

- March-April : replacing of the defective "carrassons" (wood peg), "acanage" (tying up the vine-plants) and bending the branches;
- End of April-May : complantation, which means vine by vine and not by complete plot, when it is dead or in decline. Therefore vines of very different ages can be found in the same plot.
 
This type of vineyard management implies that the grapes of young vines are identified in order to be picked separately during the Harvest; one has to pass a second time to pick the older vines of each plot. Replanting a complete plot is then decided when it has reached its limits, i.e. when the land needs to "rest" for one or two years. On average, a parcel of 2 hectares should be replanted every four years. When the choice of the parcel to replant has been made, one stops planting new vines eight years before its complete removal;

- April until the harvest : the soil is ploughed on a regular base in order to be aerated and to prevent the grass from growing;
- End of July : green harvest (thinning
the green grapes), especially on the young vines. Some of the bunches are removed -only 8 are left on average on each vinestock- thus improving the concentration of the plant nutrition;
 
- June until September : "relevage" (tying-up the shoots on wires), "rognage" (cutting) every two weeks in order to limit and to trim the growth of the vines,
- August-September : keeping up the vineyard before the harvest,

- September (and even October certain years) : harvest.
 
Besides these intensive and specific tasks, a draining system has been set in the subsoil at the beginning of the 19th century in order to help the water to flow more efficiently in the sub-soil.
