Cultivation
When cultivating Oxygonum lineare De Wild., it is best to plant them in well-draining soil. This plant prefers open, sunny locations, but it also grows well in partially shaded areas. The best practice is to plant the specimen in the spring season or the start of the rainy season.
Watering Needs
Watering the plant adequately is crucial for its growth and survival, especially during the flowering and fruiting periods. Although the plant can tolerate dry soil for some time, it requires regular watering when the soil starts to dry out. Overwatering, on the other hand, can lead to waterlogged soil and rotting of the roots.
Fertilization
Oxygonum lineare De Wild. is known to grow well in soil that is rich in nutrients. Before planting the specimen, it is advisable to amend the soil with organic matter and compost. Fertilize the plant twice a year, once in the spring and another in the fall.
Pruning
The plant does not require frequent pruning, but removing the dead or diseased parts and cutting back the unwanted growth can help maintain its shape and size. Pruning is best done in the fall or winter when the plant is dormant. Additionally, to stimulate new growth, the plant requires cutting back the tips of the flowering branches.
Propagation of Oxygonum lineare De Wild.
Oxygonum lineare De Wild. is primarily propagated by seeds and stem cuttings. Each method has its advantages and disadvantages that should be carefully considered to ensure successful propagation.
Propagation by Seeds
Seeds are the most common method used for propagating Oxygonum lineare De Wild. One can collect and store the seeds from mature plants. However, the collected seeds should be kept in a dry and cool place until planting. It is recommended to plant the seeds in well-draining soil and keep them moist. The seeds will then germinate within 10 to 15 days if the necessary conditions are met.
Propagation by Stem Cuttings
Another common method for propagating Oxygonum lineare De Wild. is stem cuttings. The gardener can cut a section of the stem with two to three nodes, preferably from a mature plant. The cuttings should be dipped in rooting hormone to enhance rooting and planted in well-draining soil. The soil should be kept moist to aid establishment of the plant.
