Sowing Vinca Seeds And Transplanting Seedlings
Vinca seeds can be sown either directly into the garden or started in trays and then transplanted. If sowing directly into the garden, it is recommended to sow the seeds approximately 2mm deep and 30cm apart. To ensure optimal germination, the soil temperature should be around 24-26°C. Germination typically occurs within 10-15 days.
If starting vinca seeds in trays, fill the trays with a suitable seed-raising mix and sow the seeds approximately 2mm deep. It is important to keep the soil moist and place the trays in a warm location. Once the seedlings have developed their first true leaves and are 5-10cm tall, they are ready to be transplanted into the garden.
Please note that vinca plants are sensitive to frost, so it is crucial to avoid transplanting or sowing seeds outside until the danger of frost has passed. In cool climates, it is advisable to sow vinca seeds indoors around six weeks before the last expected frost to give the plants an early start.
- Sow seeds approximately 2mm deep and 30cm apart if directly sowing into the garden
- Ensure soil temperature of 24-26°C for optimal germination
- Fill trays with suitable seed-raising mix for starting seeds in trays
- Keep soil moist and place trays in warm location when starting seeds in trays
- Transplant seedlings into garden when they have first true leaves and are 5-10cm tall
- Avoid transplanting or sowing seeds outside until danger of frost has passed
- In cool climates, sow seeds indoors around six weeks before last expected frost for an early start
Watering And Fertilizing Vinca Plants
Vinca plants are known for their ability to tolerate drought and thrive in dry, well-drained soil. During the early stages of growth, it is crucial to provide deep watering either in the morning or late afternoon. It is important to avoid wetting the leaves as this can lead to the growth of fungal diseases.
When it comes to fertilization, vinca plants may not need additional fertilizer if the soil was properly enriched with organic matter. However, in cases of poor soil conditions, applying a high-potassium or specific flowering plant fertilizer can be beneficial in supplying the essential nutrients for vigorous and healthy growth.
Pruning And Maintaining Vinca Plants
To encourage denser growth and more abundant flowering, pinching out the growing tips of vinca plants is an optional but effective practice. This technique can result in a more compact and well-branched plant. Vinca plants usually start to flower approximately 85 days after sowing the seeds.
After the vinca plants have finished flowering, it is recommended to prune them back to stimulate new growth. It is important to remove any dead or diseased plant material and shape the plant as desired.
Tips for pinching out vinca plants:
- Pinch out the growing tips of the plants to encourage lateral branching.
- This will result in a fuller and bushier plant.
- Pinching can be done using your fingers or sharp pruners.
- Avoid cutting into the main stem, as this may weaken the plant.
Remember to also prune back the vinca plants after they finish flowering to promote fresh growth and a tidy appearance. Removing any dead or diseased plant material will help keep the plants healthy.
