How to Grow Diascia (Twinspur)
Steps Diascia (Twinspur) for Propagation with Seeds
Sowing is best when performed in spring (March and April), in a sheltered place if temperatures don’t yet exceed 60°F (15°C).
Seeds can be sown directly in the garden.
However, it is best to prep the seeds indoors at least 8 to 10 weeks before the last frost.
The prepped seeds should be planted outdoors once the soil has started warming up and the temperature reaches 60° degrees Fahrenheit (15° C).
The ideal temperatures maintained should be between 60° – 65° degrees Fahrenheit (15° – 18° C) until the germination process starts.
The germination of this plant requires sufficient light.
Therefore, it is best to firmly press the seeds at the surface of the soil, instead of covering it.
Ensure the soil stays moist for the roots to establish.
The germination process typically takes around two weeks.
You can plant directly in the ground starting in May, or transplant your seedlings to garden boxes and pot arrangements.

- Pinch off lower leaves to keep only the highest pair of leaves.
- It is possible to dip the cuttings in powdered rooting agents, if you have any.
- Plant the cuttings in special cutting soil mix.
- Water regularly.
- Transfer the cuttings to a spot that's out of the cold in winter, so that they stay at 50 to 60°F (10 to 15°C).
How to Care for Diascia (Twinspur)
You'll get the most blooms by keeping your diascia in full sun, but in really hot weather, the plant will do best when grown in partial shade, particularly afternoon shade.
Diascia prefers a slightly acidic soil pH. Something between 6.0 and 6.5 seems to be ideal. The soil should be fertile and well-drained.
New plantings should be watered daily for a couple of weeks. After that, depending on the weather and soil type, watering can be adjusted to every two or three days. Clay soils hold moisture longer than sandy soils, so expect to water more frequently in sandy settings.
Different plants have different water needs. Some plants prefer staying on the dry side, others like to be consistently moist. Refer to the plant label to check a plant’s specific requirements.
Ideally water should only be applied to the root zone - an area roughly 6-12” (15-30cm) from the base of the plant, not the entire plant. A soaker hose is a great investment for keeping plants healthy and reducing water lost through evaporation. Hand watering using a watering wand with a sprinkler head attached is also a good way to control watering. If the garden area is large, and a sprinkler is necessary, try to water in the morning so that plant foliage has time to dry through the day. Moist foliage encourages disease and mold that can weaken or damage plants.
To check for soil moisture use your finger or a small trowel to dig in and examine the soil. If the first 2-4” (5-10cm) of soil is dry, it is time to water.
Temperature and Humidity
Diascia prefers cooler temperatures, and it flowers best in the spring and fall. If your plants start to fade in the heat, cut them back to a few inches and keep them watered. They will perk back up when it cools off.
Diascia is somewhat frost-tolerant and can be kept going well into the fall. If you’re willing to move your pots into the garage whenever a hard frost threatens, they will last even longer.
Feed the plant is relatively rare, only 1 time in 30 days. To do this, use a solution of fertilizers for flowering garden plants, while its concentration should be quite weak. If the soil is too many nutrients, the bushes may not bloom at all. In addition, in the too fertile soil, there is an elongation of the shoots of Diascia, which it loses its decorative effect.
Pinch-out the growing tips of young plants to encourage more bushy growth. Deadhead regularly to extend the flowering period.
Pests and Diseases
Diseases are not a significant issue for the diascia plants
unless they experience a highly wet season. The major pest issue for these plants is slugs and snails. It is best to lift the plants from the ground to avoid the pests or use a mild spray to eliminate them.
