Good Outdoor Plants For Pots

Good Outdoor Plants for Pots

Container gardening offers a flexible and accessible approach to cultivating plants in various outdoor spaces. Potted plants enhance patios, balconies, decks, and even small yards, providing an opportunity to showcase vibrant colors, textures, and forms. Selecting the right plants for containers is crucial for success, as the confined environment presents unique challenges and requirements. This article explores several excellent outdoor plant options suitable for pots, outlining their characteristics and care considerations.

Understanding Potting Mix and Drainage

Before selecting plants, understanding the importance of potting mix and drainage is essential. Garden soil is generally too dense for containers, impeding drainage and aeration. A high-quality potting mix designed for containers should be used. These mixes typically consist of peat moss, perlite, vermiculite, and other ingredients that promote proper drainage, aeration, and water retention. Drainage holes are crucial in all pots to prevent waterlogging, which can lead to root rot. Adding a layer of gravel or broken pottery at the bottom of the pot is generally not recommended, as it can impede drainage rather than improve it. Focus should be on using a well-draining potting mix and ensuring adequate drainage holes.

Watering frequency depends on the type of plant, pot size, and weather conditions. Container plants tend to dry out more quickly than plants in the ground, especially during hot and windy weather. Consistent monitoring of the soil moisture is necessary. When the top inch or two of soil feels dry to the touch, it's time to water. Water thoroughly until water drains out of the drainage holes. Avoid frequent, shallow watering, which can encourage shallow root growth and make plants more susceptible to drought stress.

Flowering Plants for Pots

Many flowering plants thrive in pots, offering an array of colors and textures to brighten outdoor spaces.

Petunias are exceptionally popular for their prolific blooms and versatility. They come in a wide range of colors and forms, including trailing varieties ideal for hanging baskets and window boxes. Petunias prefer full sun and well-drained soil. Regular deadheading (removing spent flowers) encourages continuous blooming throughout the growing season. Fertilizing regularly with a balanced liquid fertilizer also promotes abundant flowers.

Geraniums (Pelargoniums) are another classic choice for containers. They are relatively drought-tolerant and produce bright, showy flowers in shades of red, pink, white, and purple. Geraniums also prefer full sun and well-drained soil. Deadheading spent flowers is essential for encouraging continuous bloom. There are various types of geraniums, including zonal geraniums, ivy geraniums (which are excellent for trailing), and scented geraniums, each with unique characteristics.

Impatiens are a shade-loving option that can add vibrant color to areas with limited sunlight. They produce masses of flowers in a wide range of colors and are relatively easy to care for. Impatiens require consistently moist soil and protection from direct sunlight, which can scorch their leaves. Regular fertilization helps promote vigorous growth and abundant flowering. New Guinea impatiens are more sun-tolerant than traditional impatiens but still benefit from some shade, especially during the hottest part of the day.

Begonias are a diverse group of plants that offer options for both sun and shade. Wax begonias are sun-tolerant and produce small, abundant flowers in shades of red, pink, and white. Tuberous begonias are better suited for shade and produce large, showy flowers in a variety of colors. Begonias prefer well-drained soil and regular fertilization. Avoid overwatering, as this can lead to root rot. Different types of begonias have varying needs, so it's important to research the specific type being grown.

Pansies and Violas provide early-season color and are well-suited for cooler temperatures. They bloom profusely in spring and fall and can tolerate light frost. Pansies and violas prefer well-drained soil and partial shade. Deadheading spent flowers encourages continuous blooming. They are excellent for adding color to containers in early spring before other plants have fully emerged and again in the fall when other flowers are fading.

Foliage Plants for Pots

Foliage plants provide texture, form, and color to containers, even when flowering plants are not in bloom. They can also serve as a backdrop for flowering plants, creating a more visually appealing display.

Coleus is prized for its vibrant, colorful foliage. It comes in a wide range of leaf patterns and colors, including shades of red, pink, purple, green, and yellow. Coleus prefers partial shade and moist, well-drained soil. Pinching back the growing tips encourages bushier growth. While some coleus varieties produce small flowers, they are typically removed to promote foliage growth. There are sun-tolerant varieties of Coleus available, but even these benefit from some shade during the hottest part of the day.

Sweet Potato Vine (Ipomoea batatas) is a vigorous trailing vine with colorful foliage. It comes in a variety of colors, including chartreuse, purple, and bronze. Sweet potato vine prefers full sun and well-drained soil. It is relatively drought-tolerant once established. Regular pruning can help control its growth and prevent it from becoming too leggy. Sweet potato vines add a cascading effect to containers and can be paired with other plants to create a dynamic display.

Dusty Miller (Senecio cineraria) is a silver-leaved plant that provides a striking contrast to other foliage and flowers. It is relatively drought-tolerant and prefers full sun. Dusty miller is often used as an accent plant in containers and borders. Its soft, woolly foliage adds a unique texture to the garden.

Ornamental Grasses add texture and movement to containers. There are many varieties of ornamental grasses suitable for pots, including fountain grass, feather grass, and Japanese blood grass. Ornamental grasses prefer full sun and well-drained soil. They can be used as a focal point in a container or as a filler plant to add height and texture. They also provide winter interest when left standing throughout the winter months.

Heuchera (Coral Bells) offers a wide range of foliage colors, including shades of green, purple, bronze, and silver. Heuchera prefers partial shade and well-drained soil. It is relatively low-maintenance and adds a touch of elegance to containers. Many varieties also produce small, bell-shaped flowers. Heuchera are particularly well-suited for woodland-themed containers and can also be used as groundcover in shady areas.

Vegetables and Herbs for Pots

Container gardening is not limited to ornamental plants. Many vegetables and herbs also thrive in pots, providing fresh produce for the home gardener.

Tomatoes are a popular choice for container gardening. Choose determinate (bush) varieties, which are more compact and well-suited for pots, over indeterminate (vining) varieties, which require staking and more space. Tomatoes require full sun and well-drained soil. Provide support for the plants as they grow. Regular watering and fertilization are essential for producing a good harvest.

Peppers are another excellent choice for containers. They require full sun and well-drained soil. Like tomatoes, peppers benefit from regular watering and fertilization. There are many varieties of peppers to choose from, ranging from mild bell peppers to hot chili peppers. Support may be needed for taller pepper plants to prevent them from toppling over.

Lettuce and other leafy greens can be easily grown in containers. They prefer partial shade and consistently moist soil. Harvest the outer leaves as needed, allowing the inner leaves to continue to grow. Succession planting (planting new seeds every few weeks) ensures a continuous harvest throughout the growing season.

Herbs are well-suited for container gardening. Many herbs, such as basil, mint, rosemary, and thyme, thrive in pots. Most herbs prefer full sun and well-drained soil. Regular harvesting encourages bushier growth. Be mindful of the specific needs of each herb; some herbs, like mint, can be invasive and are best grown in containers to prevent them from spreading.

Strawberries can also be successfully grown in containers. Choose everbearing varieties, which produce fruit throughout the growing season. Strawberries require full sun and well-drained soil. Regular watering and fertilization are essential for producing a good harvest. Hanging baskets are an excellent way to grow strawberries, as they allow the plants to cascade over the sides of the container.

Key Considerations for Success

Selecting the right plants is only one aspect of successful container gardening. Several other factors contribute to healthy and thriving potted plants.

Pot Size: The size of the pot is crucial for the health of the plants. Too small a pot restricts root growth and can lead to nutrient deficiencies and water stress. Choose a pot that is appropriately sized for the mature size of the plant. Larger plants generally require larger pots.

Fertilizing: Container plants rely on the gardener to provide essential nutrients. Regular fertilization is necessary to ensure healthy growth and abundant flowering or fruiting. Use a balanced liquid fertilizer or slow-release fertilizer according to the label instructions. The frequency of fertilization depends on the type of plant and the fertilizer being used.

Pest and Disease Control: Container plants are susceptible to the same pests and diseases as plants in the ground. Monitor plants regularly for signs of pests or diseases and take appropriate action. Insecticidal soap, horticultural oil, and neem oil are effective treatments for many common pests. Ensure good air circulation around the plants to prevent fungal diseases.

Sunlight and Exposure: The amount of sunlight a plant receives is critical for its health. Pay attention to the sunlight requirements of each plant and choose a location that provides the appropriate amount of light. Some plants require full sun (at least six hours of direct sunlight per day), while others prefer partial shade (two to six hours of direct sunlight per day), and still others thrive in full shade (less than two hours of direct sunlight per day). Also, consider the exposure to wind, which can dry out plants quickly. Protection from strong winds may be necessary.
