Rejuvenation
Yearly observations have shown that rose plantations do not have a uniform rate of production. In the first 5 to 6 years the flower yield rises, but after the sixth year the flower production declines. After 8-10 years, the roses become unprofitable, necessitating rejuvenation. Autumn is the most favourable time for rejuvenation. The bushes are cut down to the base and on both sides of the rows, trenches 18-20 cm deep are opened and the soil is spread in the inter-row space. In these rows, 20-30 t of FYM along with 60 kg/ha each of P2O5 and KO2 are placed and covered with soil. In the spring, new shoots develop and out of them only six to eight vigorous branches are allowed to grow. After 2 years, the yields of rose flowers reach the previous level and the life of plantation is increased by a further 8-10 years. |
