PropagationYou may either grow these plants from seeds or buy seedlings or plants from garden stores. Plant the seeds indoors, at least two months before the last frost. You may also sow the seeds directly in the garden, just before the last frost date. Use fertile, well-drained soil for growing the seeds indoors. You may also use peat for this purpose. Apply a thin layer of soil above the seeds, as they need light to germinate. The ideal temperature range for germination is 64°F to 70°F. Keep the soil moist throughout the germination period that may last from one week to a month. Once the seedlings attain a height of a few inches, you may transplant them. If you want to sow the seeds outdoors, wait for a week after the last frost. You may also grow new plants from stem cuttings.
PlantingSoil: Grow torenia plants in well-drained, moist, and fertile soil. If you want to plant them on flower beds, till the soil and mix a generous amount of compost. Apply a bit of general purpose fertilizer. Though the ideal pH level ranges between 5.6 to 7.5, the plant may tolerate slightly higher or lower levels of pH. Leave a gap of ten inches in between the plants so that they get enough space to grow and spread. Add a layer of mulch to retain the moisture in the soil.

Light: Another important factor that affects the growth and flowering of torenia is light. These plants need sun as well as shade. If grown in complete shade, the plant may not bloom and the foliage will develop a faded look if the plant grows in full sun. So, choose a location where the plant will be exposed to sun throughout the morning or afternoon. In regions with very hot summers, plant torenias in a location where they will get morning sun and afternoon shade. In regions with cooler summers, grow them in a location with full afternoon sun and morning shade.
Watering and FeedingTorenias need moist soil for a healthy growth. So, regular watering is one of the important aspects of torenia care. However, avoid overwatering, as soggy soil will cause root rot. Plants growing in containers require frequent watering, when compared to those growing on the ground. Feed the plants with an NPK fertilizer once in every month. Sprinkle the fertilizer granules around the plant, but leave a gap of at least three inches from its base. Once done, water the plant as well as the soil.
Pests and DiseasesTorenia plants are resistant to a wide range of pests and diseases. However, they may sometimes develop fungal diseases like powdery mildew, which can be prevented to a certain extent with good air circulation. This ensures that the leaves do not stay wet for a long time. Whiteflies and aphids may also attack torenia plants. Use proper pesticides for getting rid of these insects. Neem oil is a good remedy for whiteflies as well as powdery mildew. Use it as per the instructions of the manufacturer.
