Comprehensive Care Guide for Begonia Million Kisses

To ensure your Begonia ‘Million Kisses’ thrives and delivers its spectacular display, provide optimal conditions that support its vigorous growth and abundant flowering.

1. Light Requirements

Partial Shade is Preferred: Begonia ‘Million Kisses’ performs best in partial shade, meaning it should receive 2-4 hours of direct sunlight, preferably in the morning, followed by shade during the intense afternoon hours.
Avoid Intense Afternoon Sun: Direct, harsh midday and afternoon sun can scorch its leaves and fade its vibrant blooms, especially in hot climates. While some cultivars might tolerate more sun in cooler regions, protecting them from the most intense light is generally recommended.
Optimal Performance: Dappled sunlight or bright, indirect light throughout the day will encourage the most prolific flowering and healthiest foliage.
Indoor Placement: If grown indoors, a bright location with indirect light, such as an east or north-facing window, is suitable.

2. Watering

Consistently Moist, Well-Drained Soil: Begonia ‘Million Kisses’ requires consistently moist soil to support its abundant flowering. However, like all begonias, it is highly susceptible to root rot if the soil becomes waterlogged.
Check Before Watering: Water when the top 1 inch (2.5 cm) of soil feels dry to the touch. Due to its vigorous growth and location in hanging baskets (which dry out faster), daily watering may be necessary in warm, sunny conditions.
Thorough Soaking and Drainage: Water deeply until water drains from the bottom of the pot. Always use containers with ample drainage holes and promptly empty any excess water from saucers or cachepots.
Avoid Wetting Foliage: To minimize the risk of fungal diseases, water at the soil level, keeping the leaves and flowers dry.

3. Soil and Potting

Well-Draining, Humus-Rich Soil Mix: These begonias thrive in a fertile, well-draining potting mix that is rich in organic matter. A high-quality commercial potting mix formulated for flowering plants or a general-purpose mix amended with perlite or coco coir will provide the ideal balance of moisture retention and aeration.
pH Preference: They are adaptable but generally prefer a slightly acidic to neutral soil pH, typically ranging from 5.5 to 6.5.
Container Choice: Select pots that are large enough to accommodate their vigorous growth and spreading habit. For hanging baskets, choose a size that allows for adequate soil volume to retain moisture. Always ensure the container has ample drainage holes.

4. Temperature & Humidity

Warmth Lovers: Begonia ‘Million Kisses’ thrives in warm temperatures, with an ideal range generally between 65∘F and 80∘F (18∘C to 27∘C). It is not frost-hardy and will be damaged or killed by freezing temperatures.
Avoid Cold Snaps: Protect plants from sudden cold snaps or prolonged cool temperatures.
Humidity: While they are generally adaptable to average humidity levels, consistently dry air can lead to crispy leaf edges. In very dry indoor environments, increasing ambient humidity with pebble trays or a humidifier can be beneficial. Ensure good air circulation to prevent fungal issues in humid conditions.

5. Fertilization

Regular Feeding for Prolific Blooms: To sustain its continuous and abundant flowering, Begonia ‘Million Kisses’ is a heavy feeder and benefits from regular fertilization during its active growing season (late spring through autumn).
Recommended Regimen: Apply a balanced, water-soluble liquid fertilizer (e.g., NPK 10-10-10 or a bloom-boosting formula with higher phosphorus, like 10-30-10) every two weeks, diluted to half or quarter strength. Consistent feeding is crucial for maximizing bloom production.
Reduce in Dormancy: As temperatures cool in late fall or winter (if overwintered), reduce or cease fertilization, as the plant’s growth will naturally slow down.

6. Pruning and Maintenance

Deadheading for Continuous Flowering: While many begonias are somewhat “self-cleaning,” deadheading spent flowers (pinching or snipping them off) is highly recommended for Begonia ‘Million Kisses’. This encourages the plant to produce more blooms and helps maintain a tidy, attractive appearance.
Light Pruning for Shape: Lightly prune any overly leggy stems to maintain a desirable shape and encourage bushier growth. This can help prevent the plant from becoming too sparse at the crown.
Remove Damaged Foliage: Promptly remove any yellowing, damaged, or diseased leaves to maintain plant health and aesthetic appeal. Good garden hygiene helps prevent the spread of pests and diseases.
Air Circulation: Ensure adequate air circulation around and through the cascading foliage, especially in humid conditions, to help prevent fungal problems.

Propagation: Extending Your Million Kisses Display

Begonia ‘Million Kisses’ can be propagated from stem cuttings.

Select Healthy Stems: Choose healthy, non-flowering stem sections that are about 4−6 inches (10−15 cm) long, ideally in late summer or early fall.
Prepare Cuttings: Make a clean cut just below a leaf node. Remove any leaves from the bottom 1−2 inches (2.5−5 cm) that would be submerged in water or rooting medium.
Rooting Medium: Insert the cut end into a moist, well-draining rooting medium (e.g., perlite, vermiculite, or a light potting mix) or directly into a glass of water. Rooting hormone can be used to improve success rates.
Environment: Place the cuttings in a warm location (68−75∘F or 20−24∘C) with bright, indirect light. High humidity can aid rooting; covering the pot with a clear plastic bag or dome (with some ventilation) can create a mini-greenhouse effect.
Rooting & Transplanting: Roots typically develop within 2−4 weeks. Once a healthy root system is established, the new plant can be transplanted into a larger pot and cared for as a mature specimen.

Overwintering Begonia Million Kisses

As a hybrid with some tuberous characteristics, Begonia ‘Million Kisses’ is generally treated as an annual in climates with freezing winters (below USDA Hardiness Zone 9-11). However, overwintering is possible.

Digging Tubers (Optional): In colder zones, if the plant forms a significant tuber, you can carefully dig it up before the first hard frost. Clean off excess soil, allow it to air dry for a few days, and store it in a cool (40−50∘F or 4−10∘C), dry, dark place (e.g., in peat moss or vermiculite) until spring.
Indoor Overwintering (Active): If grown in containers, you can bring the entire plant indoors before frost. Place it in a bright location with indirect light and slightly cooler temperatures. Reduce watering significantly, allowing the soil to dry out almost completely between waterings. The plant’s growth will slow, and flowering will likely cease. Maintain good air circulation.
Taking Cuttings: The most reliable method for ensuring future plants is to take stem cuttings in late summer or early fall and root them indoors. These younger plants are often easier to maintain over winter and perform vigorously the following spring.

Common Pests and Diseases

Begonia ‘Million Kisses’ is relatively robust but can be susceptible to some common begonia pests and diseases.

Pests:
- Aphids, Mealybugs, Spider Mites, Whiteflies: Inspect regularly, especially under leaves. Treat with insecticidal soap or neem oil.
- Slugs and Snails: Can be an issue for outdoor plants, particularly in moist, shaded conditions.
Diseases:
- Root Rot / Stem Rot: Caused by overwatering and poor drainage. Ensure excellent drainage and allow soil to dry slightly between waterings.
