The minimum pot size refers to the diameter of the top of the pot. The height can vary but is usually classified as standard or azalea. Azalea pots are shorter and ideal for plants that have minimal roots like succulents. Standard pots are recommended for growing vegetables.
Recommended minimum diameters are tomatoes, 20 inches; Paprika, 16 inches; Radish, onion, and beets, 10 inches; Carrots, 12 inches; and herbs and flowers, twelve inches; and greens, 10 inches.
The recommended volume of soil is 10-inch pot, 3 gallons; 12 inch pot, 5 gallons; 14 inch pot, 7 gallons; 16 inch pot, 10 gallons; 18 inch pot, 15 gallons; 24 inch pot, 25 gallons; and 30 inch pot, 30 gallons.
Veranda pots that combine silver foliage tones with white flowers are trendy this year. The silver leaf plants include dichondra “Silver Falls”, lotus vine, dust mill, lavender and curry. The lotus vine has fine, silvery foliage that hangs from the side of the pot. Ornamental curry plants, related to straw flowers, claim lavender-like foliage and have small, rounded yellow flowers. The flowers sometimes detract from the silver foliage, so regular pinching is required for a bold, compact silver accent. Although its namesake and smell are reminiscent of a delicious curry dinner, this isn’t the edible type of curry.
To achieve the silver and white color combination, add annuals that provide continuous white flowers that are easy to care for, including Angelonia (summer snapdragon), Argyranthemum (daisy), Calibrachoa (million bells), Browallia (bush violet), Verbena or zinnias.
