The second half of November, when winter is gradually setting in, provides ideal conditions for planting saplings of roses, gladiolus and other decorative plants. These plants would attain maturity by the new year, states an advisory issued by the horticulture department.
Director horticulture SP Joshi said, "To have a rich yield of rose, the gardener should ensure adequate water supply in the rows where the sapling has been planted. Pruning of the irrelevant parts of the plant is also important as they could hamper the flowering process".
According to experts, a beginner planning to grow rose should purchase saplings with strong stem formation. The plant should be in a place where it receives about three hours of morning sun but not mid- afternoon sun. The plant should be cut and pruned for better growth and transplanting should be done in a bigger container.
This season is also suitable for plantation of gladiolus. Every square metre of the row where the sapling has been planted must be covered with 5-8 kg of cow dung manure, 200 gm of single super phosphate, 200 gm of murate of potash and 100 gm of urea. The distance between two gladiolus plants must be 40-50 cm.
Some varieties of gladiolus which have been approved for Uttar Pradesh are American Beauty, Archana, Arun, Yellowstone, Friendship, My Love, White Prosperity and First Lady. Fifteen days before the plantation of these saplings, the gladiolus bulbs should be taken out from cold storage and kept in a cemented and shady area with proper ventilation. Until plantation, these bulbs should be treated with spray of 3 gm of blightax mixed in 10 litres of water for 30-35 minutes.
Roses grown in weak sun may not die at once, but they weaken gradually. Give them plenty of organic matter when planting and don't crowd them.
Some recommend placing a 4-inch square of gypsum wallboard and a nail in the hole to provide calcium and iron, both appreciated by roses.
Roses will die if the soil is too wet in winter. The ideal soil is rich and loose with good drainage. To help conserve water, reduce stress and encourage healthy growth, apply a 2-4-inch layer of chopped and shredded leaves, grass clippings, or shredded bark around the base of your roses.
Good gardening practices such as removing dead leaves and canes will help reduce pests
Rose roots require good amount of air for better growth, hence the soil should be tilled at regular intervals. Watering should be done in the evening - Prof Dinesh Kumar, former HOD, botany department, Lucknow University.
"Some ornamental varieties of rose have the tendency of growing fast. When this happens, branches and sub-branches also start appearing. The best way to curb this uncontrolled growth is pruning of branches so that the plant growth is uniform," Dr AK Singh, CIMAP Lucknow
