Growth Conditions for Barleria swynnertonii S.Moore
Barleria swynnertonii S.Moore, also known as Swynnerton's dwarf Ipea, is a small shrub endemic to Tanzania. This plant requires specific growth conditions in order to thrive. The following are some of the most important factors to consider for optimal growth:
Light Requirements
Barleria swynnertonii S.Moore requires full sunlight exposure to grow well. It is best planted in an area that receives at least six hours of direct sunlight every day. If grown indoors, it is essential to ensure that the plant receives adequate light from grow lights or by placing it near a sunny window.
Temperature Requirements
This plant requires warm temperatures to grow and cannot survive in areas with temperatures below 10°C (50°F). The ideal temperature range for Barleria swynnertonii S.Moore is between 21°C (70°F) and 29°C (85°F). If planting this shrub outdoors, it is essential to avoid frost-prone areas. On the other hand, If growing the plant indoors, the temperature needs to be constantly monitored and maintained using heaters or air-conditioning units as necessary.
Soil Requirements
Barleria swynnertonii S.Moore requires well-draining soil with a pH ranging from 6.0 to 7.5. The soil should be rich in organic matter, and the addition of peat or compost is highly recommended. It is also best to plant this shrub in soil that is enriched with essential minerals and nutrients to optimize growth. It is important to avoid waterlogged or compacted soils, which could lead to the plant's death.
Cultivation
The Barleria swynnertonii S.Moore plant is native to Tanzania. Cultivation of the plant is done outside in warmer areas. The plant needs to be protected from frosts or kept indoors in cooler areas. When grown outdoors, it can reach up to 4 feet tall and wide.
Watering
The Barleria swynnertonii S.Moore plant requires moderate watering. When planting, the soil needs to be moist, and the plant should get enough water to help it establish roots. Once established, reduce the watering frequency but ensure the soil is never too dry. Overwatering can lead to root rot, so ensure the plant's soil is moist but not waterlogged.
Fertilization
Fertilize the Barleria swynnertonii S.Moore plant once a month during the growing season. The plant requires balanced nutrition that comprises both macro and micronutrients. You can use 10-10-10 or 20-20-20 nitrogen-rich fertilizers. Avoid using too much fertilizer as this can lead to leaf-burn, stunted growth or even kill the plant.
Pruning
Pruning is done to remove the dead or diseased parts of the Barleria swynnertonii S.Moore plant. Prune annually, before the growing season begins, to refresh the plant and encourage the growth of new shoots. Use clean pruning shears to make a clean cut, and avoid tearing the plant stems. Prune the plant up to a third of its total size.
Propagation methods for Barleria swynnertonii S.Moore
Barleria swynnertonii S.Moore, commonly known as Swynnerton's dwarf mouse-eared barleria, is a beautiful and intriguing plant that belongs to the Acanthaceae family. In the wild, these plants propagate through seeds, but they can also be propagated vegetatively.
Propagation through seeds
Seeds can be collected from mature fruits that have turned brown and are starting to crack open. These seeds should be carefully collected and sown in a well-draining seed-raising mix. The seeds need to be sown at a depth of about 1 cm, and the soil should be kept moist until the seedlings emerge.
It is important to note that the germination of Barleria swynnertonii S.Moore seeds can be slow and erratic, so patience is required. It can take anywhere from 4 to 16 weeks for the seeds to germinate, and not all seeds may germinate at the same time.
Propagation through cuttings
Barleria swynnertonii S.Moore can also be propagated through stem cuttings. These cuttings should be taken from healthy and disease-free plants during the active growing season. The cuttings should be about 10 cm long and should be taken from the tip of the stem.
After taking the cuttings, remove the leaves from the lower half of the stem and dip the base of the cutting in a rooting hormone. Place the cutting in a pot filled with a well-draining potting mix. Water the soil well and cover the pot with a plastic bag to create a humid environment that will encourage rooting.
Keep the cutting in a bright, warm, and protected spot, but out of direct sunlight. After about 4 to 6 weeks, the cutting should develop roots and can be transplanted into its own pot.
Propagation through division
Barleria swynnertonii S.Moore can also be propagated through division. This method involves dividing the plant into smaller parts, each with its own set of roots and stems.
To propagate through division, gently lift the plant from its pot, and carefully separate it into smaller parts, taking care to keep the roots and stems intact. Plant each division in its own pot, and water well. Keep the plant in a sheltered, shaded spot until it has established itself.
Propagation through division is best done in spring when the plant is actively growing, and new shoots are emerging.
