Tomato plants need consistent watering to yield the most healthy and flavorful fruit. When plants don’t get enough water, the result can be deformed or small tomatoes, and blossom end rot can develop (where the bottom of the tomato turns black). Because of how susceptible tomato plants are to fungus diseases, it’s best to water plants at ground level, using drip irrigation, soaker hoses or creative solutions like a tomato halo. This device holds 3 quarts of water, delivering it directly to the root zone of the plant, which encourages deep rooting. The red color of watering haloes reflects wavelengths of light to tomato plants that promote fruiting.
In this arrangement, mounds of dried moss hold their shape among other plants growing around it. "You can think of (dried moss) as a display prop to showcase" other plants, Colletti says, since it doesn't need water. The plants in this terrarium include a red-veined Fittonia and a ‘Pink Star’ Cryptanthus. The moss with dark branches is Selaginella 'Ruby Red'.
While pastel toned tulips are often associated with spring, red tulips are a perfect fit for the holidays. Once cut and placed in vessels, tulips can last up to ten days. Change the water every day or two and also cut the ends of the stems at an angle to ensure the tulips receive proper hydration. For a touch of texture, mix juniper sprigs in with the tulips.
If they’re keep in a cool spot (but out of drafts), poinsettias can last long past the holidays. Give your plant bright, indirect light and water when the soil starts to feel dry. As with most houseplants, avoid overwatering, and drain the saucer, so the plants’ roots won’t rot. Use a balanced fertilizer every couple of weeks to feed the poinsettia as long as it’s actively growing. Getting the plant to rebloom next year is difficult; most people compost their poinsettias and buy new ones each season. You can also keep them to enjoy as green houseplants after all the red "leaves" drop.
Beautiful blooms of calla lily (Zantedeschia) are a cut flower favorite that thrives in a boggy environment. Many gardeners tuck calla lily into a spot beside a pond or stream. Plants can grow in up to 1 foot of water. In cold regions, dig bulbs and store dry indoors through winter. Look for varieties that open flowers in many hues, including vibrant yellow, deep red, white and pastel shades. Plants grow 2 to 3 feet tall by 2 feet wide. Hardy in Zones 9-10.
Problem: Swarms or clouds of tiny white creatures fly into the air when you move your plants. Solution: You’ve got whiteflies, insects related to aphids that suck plant juices. They make a sticky substance called honeydew that can attract fungal diseases. Spray the plant with an insecticidal soap, following label directions. You’ll probably need to re-treat. Some gardeners use a homemade spray of 2 parts rubbing alcohol, 5 parts water and one tablespoon of mild liquid soap. The good news is that some houseplants, like this red Anthurium, are seldom troubled by these pests.
