The ideal location is one that has partial shade and some direct sunlight for a few hours of the day. This plant can be propagated through cuttings of mature stems taken from late summer to early fall. It can also be grown from seeds, which should be sown in the spring, and they will germinate within two to three weeks.
Watering Needs
The Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens. plant requires regular watering, and the soil should be kept consistently moist. However, it is essential to ensure that the soil is well-drained and does not become waterlogged. Overwatering can cause root-rot and lead to the death of the plant. In the winter months, the watering should be reduced to avoid waterlogging and ensure that the plant is not exposed to very low temperatures.
Fertilization
This plant does not require excessive fertilization, but a slow-release fertilizer may be added during the spring to provide essential nutrients. Additionally, a balanced fertilizer can be applied once in a while during the growing season to encourage healthy growth. It is essential not to over-fertilize as these plants are susceptible to nutrient burn, which can damage their leaves and flowers.
Pruning
Hypericum sphaerocarpum Michx. var. turgidum requires minimal pruning. However, some pruning may be necessary in the spring to remove any dead or diseased leaves, broken stems, or branches caused by winter winds. During the growing season, occasional pinching will encourage bushier growth, but this is not strictly necessary. After flowering, some pruning can be done to maintain the plant's size and shape.
Propagation of Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens.
Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens. can be propagated through different methods, which include:
Seed Propagation
The most common and efficient method of propagating Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens. is through seed propagation. The seeds from the plant are sown in a well-aerated medium and kept moist. The medium should be well-draining since the plant cannot tolerate water-logged conditions. The seeds should only be covered with a thin layer of soil.
The seeds should be exposed to appropriate light conditions and temperatures to enhance germination. The recommended temperature range should be between 68°F to 86°F and should be consistent. It takes between 2-4 weeks for the seeds to germinate.
Cuttings Propagation
Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens. can also be propagated through cutting. The stems of the plant cut into a length of 3-6 inches, which are then dipped into rooting hormones. The cuttings are placed in soil, pumice, perlite or vermiculite to enhance rooting. It’s essential to provide the right light conditions, which should be bright to prevent the cuttings from drying out.
The cuttings should be kept moist but not waterlogged. A high humidity level around the cutting is vital for successful rooting. This can be achieved by covering the stem cutting with a plastic bag, which should be removed once roots start to develop.
Division Propagation
Hypericum sphaerocarpum Michx. var. turgidum (Small) Svens. can also be propagated through division. This method is usually done in spring when the plant is mature. The root system is then divided into sections, separating the plantlets, and each is potted separately.
The new plant should be given the appropriate moisture level and light conditions, which should be bright, but the plant should be protected from direct sunlight until it’s established.
