For bold seeded flower crops viz. balsam, calendula, dahlia, ipomea, nasturium, ornamental gourds, sunflower, tithonia, thunbergia etc.
The seeds can be sown directly into the pots or flower beds. The beds have to be prepared finely by adding compost. The seeds have to be sown at one cm depth with two seeds per hill (in hybrids one seed per hill) and one food apart. Water the beds gently and maintain the moisture of the beds by regular watering. Once the seeds have germinated, thin out the seedlings to maintain one seedling per hill.
For medium sized flower varieties viz. African marigold, aster, acroclinium, centuarea, chrysanthemum, coreopsis, cosmos, French, marigold, gaillardia, gazania, gomphrena, helichrysum, melampodium, mirabills, vinca, zinnia etc.
The nursery beds have to be prepared finely by adding compost. Grooves of half cm deep have to be made and covered with thin layer of soil. Drench the bed with captain or blue copper solutions @3g per liter of water. Cover the beds with straw of paper. The seeds take 4-6 days to germinated, as soon as you see that the seeds are just germinating, remove the straw or paper. After four weeks the seedlings will be read for transplanting to flower beds or big pots.
For small seeded flower varieties viz. ageratum, alyssum, begonia, carnation, celosia, kochia, cineraria, coleus, dianthus, gypsophila, impatiens, petunia, pansy, phlox, portulaca, statice, viola, verbena etc
The sowing medium should contain sieved leaf mould or compost, sand and ted soil in equal proportions. Pour the medium in a wooden box of size 1' X 1.5' X3" or seed pans and press uniformly. Make half cm deep groove, using a wooden stick. Spray captain or blue copper @3g per liter of water till the media is completely drenched. So the seed s thinly in the groove and spray the fungicide solution again. Do not cover the seeds with medium. Cover the box with a transparent plastic sheet and keep in shaded place. The seeds take 4-6 days to germinate. As soon as you notice that the seeds are just germination, remove the cover and expose at the seedlings to partial shade, otherwise seedlings will become lanky. Gradually you can keep the box or seed pan in full sunlight. After four weeks the seedling will be ready for transplanting to flower beds or big pots.
Fertilizer (17 : 17 :17 ) application [ 1g per liter of water ] has to be stared ten days after transplanting ( 30 days after sowing in case of direct sown crops). This can be repeated once in ten days. Spray 1.5g of dittany M-45 during rainy season once in 15 days.
For places like Bangalore, flower crops can be grown all round the year with better care during summer months.
