Growing and Caring for Silver Falls Plant: A Comprehensive Guide
Introduction
Silver Falls Plant (Dichondra argentea), a member of the Convolvulaceae family, is a popular ornamental plant known for its cascading, silvery-green foliage. Originating from desert regions of the southwestern U.S. and northern Mexico, this creeping perennial adds a touch of elegance to hanging baskets, rock gardens, and raised beds.
Growing Conditions
Silver Falls Plant thrives in well-draining soil and full sun exposure. It prefers slightly acidic to neutral soil pH, ranging from 5.5 to 6.5. This versatile plant can tolerate light shade, especially in hotter climates.
Water Requirements
As a desert native, Silver Falls Plant prefers dry soil conditions. Water sparingly, allowing the soil to dry out between waterings. Overwatering can lead to root rot, especially in hanging baskets.
Temperature and Humidity
Optimal temperatures for Silver Falls Plant range from 68°F to 75°F. It can tolerate temperatures up to 85°F, but prolonged exposure to higher temperatures can cause heat stress. The plant is not frost-hardy and will succumb to damage at temperatures below 25°F.
Fertilization
Annual Silver Falls plants generally do not require feeding if the soil contains adequate nutrients. However, bedding plants and ground covers can benefit from a balanced NPK fertilizer applied in early spring.
Propagation
From Seed:
- Start seeds indoors 12 weeks before the last frost using a seed-starting mix.
- Press seeds into the soil but do not cover them, as they require light to germinate.
- Cover the tray with a plastic dome to maintain humidity.
- Germination typically occurs within 4 to 15 days.
- Transplant seedlings into individual containers once they have developed several sets of true leaves.
- Harden off seedlings gradually before planting them outdoors after the danger of frost has passed.
By Division:
- Dig up a section of the plant that has rooted at a leaf node.
- Replant the rooted section in a new location.
Pruning
- Prune trailing foliage to encourage a lusher, fuller appearance.
- Remove growing tips as far back as the fourth set of leaves.
- Snip regularly throughout spring and summer to maintain the plant’s shape.
- Avoid pruning plants that are overwintered indoors.
Overwintering
- Silver Falls Plant is not typically kept as a houseplant, but it can be brought indoors if temperatures drop below 50°F.
- Choose a warm, well-lit spot and keep the soil relatively dry.
- Wilted leaves will revive after watering.
- Move plants back outdoors after the danger of frost has passed.
Pests and Diseases
- Dichondra flea beetles can be a problem in western states.
- Otherwise, Silver Falls Plant is generally free of serious pests and diseases.
Common Problems
Wilted, Yellowing Foliage:
- Caused by insufficient watering.
- Water the plant thoroughly and the foliage will perk up.
Root Rot:
- Symptoms include yellow or brown leaves, stunted growth, and dieback.
- Caused by overwatering.
- Withhold water or repot the plant in fresh, dry potting mix.
Sparse Foliage:
- Caused by excessive growth.
- Trim back foliage regularly to encourage a full, lush appearance.
