Devitalized and weak bonsai :
Always use in first application NATUREL COMPOST, GREEN POWER and VITALITE PRINTEMPS even in autumn. The following spring, make a repotting.

For greedy species in fertilization :
Do not increase the amount, but divide by two and fertilize more often.

If you go go out for a few days :
Cut out a felt thin strap of approximately 20 cm long, place it between the bonsai and the bottom of the pot, through the drainage's hole and let it soak in a small basin filled with 5 cm of water (the bonsai will be placed on two small pieces of wood to prevent it from soaking directly in water).

If your bonsai has suffered from water excess :
Let dry the clod a little bit, make a light branch's cutting, use GREEN POWER with the amount indicated and add NATUREL COMPOST. Place then your bonsai in a hot and luminous place. Sprinkle moderately thereafter by applying our fertilization's method.
