Care Instructions for Portulaca (10 O’Clock)

Light: Portulaca (10 O’Clock) loves the sun! It thrives in full sun and requires at least 6 hours of direct sunlight per day to produce its vibrant blooms. In fact, the plant blooms more profusely the more sunlight it receives. If growing indoors, place it near a south-facing window or under grow lights. This plant can tolerate high heat and intense sunlight, making it an ideal choice for hot, sunny gardens or patios.

Watering: Portulaca is highly drought-tolerant due to its succulent nature. Water it thoroughly when the soil feels dry, but always ensure the pot or garden bed has good drainage to prevent waterlogging. Overwatering can lead to root rot, so allow the soil to dry out between waterings. During the growing season (spring through summer), water about once every 5-7 days, but reduce watering frequency in the fall and winter when growth slows.

Soil: Portulaca (10 O’Clock) prefers well-draining, sandy or loamy soil. It does best in slightly acidic to neutral pH levels. If planting in containers, use a cactus or succulent mix to ensure adequate drainage. Avoid heavy, clayey soils, as they tend to retain moisture, which can lead to root rot. If planting in the ground, amend the soil with sand or perlite for better drainage.

Temperature: Portulaca thrives in warm temperatures between 70°F (21°C) and 90°F (32°C). It is heat-tolerant and loves the sun, but can struggle in temperatures below 50°F (10°C). If you live in a cooler climate, you can grow this plant as an annual or in containers that can be brought inside during the colder months. Avoid planting it in areas with frost risk.

Humidity: Portulaca is a low-maintenance plant that tolerates dry air well. Unlike many other plants, it does not require high humidity levels and will thrive in normal household conditions. Outdoor plants may need occasional watering during dry spells, but in general, this is a plant that does well in arid climates and can survive with minimal moisture.

Fertilization: Portulaca (10 O’Clock) is a relatively light feeder. Apply a balanced fertilizer once a month during the growing season (spring and summer) to encourage healthy growth and abundant flowering. Avoid excessive fertilization, as it can lead to more leaves and less flowering. Use a water-soluble fertilizer with equal parts nitrogen, phosphorus, and potassium. No need to fertilize in the winter when the plant is dormant.

Pruning: This plant requires very little pruning. Simply remove any dead or wilted flowers to encourage new blooms and maintain its tidy appearance. You can also trim back leggy growth to promote bushier growth and a more compact form. Pruning is best done in early spring before the plant begins its new growth cycle
