Thus, it is advisable to place the plant in a location where it can receive sufficient indirect sunlight and a few hours of direct sunlight every day.
Temperature Requirements
This plant can tolerate a wide range of temperatures. However, it grows best in temperatures ranging from 60 to 75°F during the day and 50 to 65°F during the night. Too much heat can cause the plant to wilt and dry out quickly, while freezing temperatures can kill it. Therefore, it is essential to keep the plant in a location with a stable temperature throughout the year.
Soil Requirements
Oxalis illinoensis Schwegm. prefers well-draining, light-textured soils rich in organic matter. It can grow in different soil pH levels, but it thrives in slightly acidic to neutral soils with a pH range of 6.0 to 7.0. Additionally, the plant prefers moist soil but does not tolerate waterlogged soil, which can cause root rot. It is important to water the plant only when the top inch of the soil is dry.
Cultivation methods for Oxalis illinoensis Schwegm.
Oxalis illinoensis Schwegm. is a herbaceous perennial plant that grows best in full to partial sunlight and well-drained soils. It is a hardy plant that can tolerate different soil pH levels, but it prefers slightly acidic soil conditions with pH ranging from 5.5 to 6.5. It can be propagated from seeds or division of clumps, and it grows well in containers or the ground.
Watering needs for Oxalis illinoensis Schwegm.
Oxalis illinoensis Schwegm. requires regular watering, especially during the growing season, to keep the soil moist. However, it is essential to avoid overwatering, as this can lead to root rot. Water the plant deeply once a week, or more frequently if the weather is hot and dry. Water the soil directly around the plant, keeping the leaves as dry as possible, as this can reduce the risk of fungal infections.
Fertilization of Oxalis illinoensis Schwegm.
Oxalis illinoensis Schwegm. benefits from regular fertilization to encourage healthy growth and blooming. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer every three to four weeks during the growing season, and follow the manufacturer's instructions for the correct dosage. Avoid over-fertilizing, as this can lead to excessive foliage growth and decreased blooming.
Pruning Oxalis illinoensis Schwegm.
Oxalis illinoensis Schwegm. does not require extensive pruning, but regular deadheading can encourage prolonged blooming. Remove dead flowers and stems as soon as they appear, as this can prevent the plant from wasting energy on seed production. Avoid cutting back the foliage too severely, as this can weaken the plant and reduce blooming the following year.
Propagation of Oxalis illinoensis Schwegm.
Oxalis illinoensis Schwegm. can be propagated through different methods including seeds, bulbs, and division.
Propagation from Seeds
