Trade out your tired patio tomatoes and peppers for cool season spinach, lettuces, kale and parsley. Mix them with pansies for an edible fall container planting, says Cameron Watkins of C. Watkins Garden Co.
Winds tunneling through high rises and neighborhoods can be damaging and drying. Adjust watering as needed and provide supports for tall plants or decorative fencing/screening as a wind break, says Melinda Myers, an urban gardener.
Potting mix that has fertilizer in it will give your houseplants or other container plants a good start. But eventually, the nutrients will either be used up, or they'll leach out after frequent waterings. When your plants are ready for a boost, apply a slow release fertilizer that lasts for several months, or feed more often with a liquid or water-soluble fertilizer. Stop fertilizing if your indoor plant goes into a period of dormancy for awhile.
A small collection of bonsai adds an element of green to the space. The indoor Japanese container garden utilizes natural stone that is in keeping with the the stone elements seen in the outdoor space. A few stepping stones allows for easy access into the garden.
Bring on the blooms with Mistral Yellow begonia. This sunny beauty is a type of Begonia boliviensis, which pumps out flowers all summer long. Showcase Mistral Yellow in a hanging basket or tall container. Plants form tubers that overwinter easily in the pot. Slip the pot into a non-freezing, cool, dark location for winter. Barely water once a month. Tubers start sprouting in spring, signaling it’s time to move the plant into bright light.
Toucan Scarlet canna is a smaller version of the classic canna, growing 3 to 4 feet tall. It’s a perfect size canna for container gardens. Here it’s planted with Vermillionaire firecracker plant (orange flowers) and purple annual salvia.
Selaginella moss, also known as peacock moss, is nestled in a decorative container. This variety of moss likes moist soil and high humidity, says Karin Jeffcoat, owner of Cote Designs. When planting into containers with no drainage, she lines bottom with pea gravel. Placing plants with their pots into the container allows her to water them individually. She also adds water to the bottom of the container to allow for humidity.
With various sized bins and a range of lids, it doesn’t take much for your collection of leftover holders to get out of hand. Lufkin and Goodsell say to group bottoms, then stack lids vertically with the help of a plate rack.
Fill a pot with flowers and plants that thrive in autumn’s cool air. Sweet alyssum, pansy and snapdragon all blossom strongly during chilly days. Many grasses and grass type plants (like Carex)—both the perennial and annual types—hold their own as temps start to tumble. Count on grasses to add texture and/or an upright element to cold weather container gardens.
