Soak the seeds 24 hours before sowing in tepid water. Sow indoors in trays or individual pots from end of march till mid april and put the trays or pots in a warm room or propagator. Make sure the germination temp. is about 18 °C and keep this temperature as constant as possible. Don't let the temperature drop during the night. Cover the seeds with a layer of potting soil. Keep moist and warm during sowing and germination. Cover the tray or pots with a lid or some clingfilm. After about 10 -14 days the seedlings emerge. Remove the lid or clingfilm when the seedlings have emerged. Harden the seedlings of for approx. 10 - 14 days by putting them in the sun during the day from the first of may or put them in a coldframe. Plant the seedlings outdoors in the middle may, when there's no longer any danger of nightfrosts. Put the seedlings on a sunny plot with free draining and sandy soil and keep the plants about 30 cm apart. Don't fertilize the plants because this causes to much foliage growth and not enough flower growth. Don't overwater the Nasturtium plants.
