How to sow periwinkle seeds? Teaching you the correct sowing method

  Periwinkle has a long flowering period, bright flower colors, and graceful form, and with the development of modern technology, the periwinkle varieties people have bred are becoming more and more beautiful. It is very suitable as an indoor potted ornamental plant, and keeping one at home may produce unexpected effects.

  Beautiful flowers require good seedlings. Periwinkle seeds are not large in appearance, and it is itself a perennial variety that blooms in all four seasons. Therefore, the seedling-raising conditions are relatively flexible, and the recommended seedling-raising time is from January to April. After sowing and raising seedlings in seedling plugs, make sure the temperature is maintained at around 20 degrees, so that the seeds can successfully sprout and achieve the seedling-raising effect.

  Because periwinkle comes in many colors and has a long flowering period, it is very popular among flower enthusiasts. Periwinkle is mostly grown from seed for seedlings, and of course it can also be propagated by cuttings, but seedlings propagated by cuttings are not as robust in growth as seed-grown seedlings.

  Sowing time: (mostly) spring and summer

  Germination temperature: 15-25 degrees

  Suitable growth temperature: 10-30 degrees

  Periwinkle is mostly propagated by sowing. When sown in early spring, the seedlings grow slowly in the early stage. When the seedlings grow to 3-4 true leaves, begin thinning and transplanting, and when they have 6-8 pairs of true leaves, they can be planted in place. When planted in flower beds in May, water once every 3-5 days, and appropriately apply additional phosphorus and potassium fertilizer, and then there will be many flowers and lush leaves. Below is an introduction to the sowing and seedling-raising method for periwinkle.

  1. Sowing time

  Periwinkle is generally sown around March to May in spring. Generally speaking, to make periwinkle bloom earlier, it can be sown and raised as seedlings in a greenhouse in early spring, giving it a 20°C environment, and moved to open ground for cultivation when the weather warms up in spring.

  2. Sowing medium

  The medium is best prepared with peat + perlite at a ratio of 3:1. Leaf mold can also be used. Water thoroughly with 500-600 times diluted carbendazim solution (for sterilization), and place the seedling container in a south-facing sunny place.

  3. Key points of sowing

  After sowing, cover with fine thin sandy soil, do not let the seeds be directly exposed to light, water thoroughly with a fine watering can, and cover with plastic film or a straw curtain to keep the soil moist. Seedlings will emerge in 7-10 days.

  4. Seedling management

  After periwinkle seedlings emerge, gradually increase light. Because periwinkle seedlings grow slowly, and grow faster after the temperature rises. Thin the seedlings in time (that is, remove the weak and small seedlings; reasonable thinning helps make the flower seedlings grow stronger).

  Generally, flower enthusiasts buy periwinkle seeds directly for sowing, and some save their own seeds. Here is a brief mention of the time to collect periwinkle seeds. Because the fruit of periwinkle matures at different times depending on the flowering time, the seeds should be collected as they mature. After the fruit matures and its color turns black, the skin easily splits open and causes the seeds to be lost, so seeds need to be collected in time. When you see the fruit skin turning yellow and can faintly see the black seeds inside, it is time to harvest.
