Question: Is it true that daffodils can't be put in the same vase with other flowers?
Answer: Daffodils produce a sap that can reduce the vase life of other flowers. It's best to either keep them as a separate bouquet, or allow them to sit in their own vase of water for a day before adding them to an arrangement with other fresh flowers.
Question: I'm new to gardening, and last year I started seeds indoors. They were growing nicely, but then toppled over! What happened?
Answer: Sounds like your seedlings succumbed to damping off, a disease caused by a soil-borne fungi called fusarium, which weakens stems so they can no longer take up water. Overwatering and poor air circulation encourage the disease. Next time, allow more space between seedlings. Water only as needed, preferably in the morning on sunny days, and place a fan near the plants to keep the air circulating.
Question: When can I repot my houseplants? Are there any rules I must follow?
Answer: It's a good practice to repot houseplants every year, and spring is an excellent time. Repotting will help your plants grow larger, and it is an opportunity to replenish the soil with nutrients that will give your plants a boost. Select a pot that is one size bigger than the one your plant is currently growing in. Gently remove the plant from its pot by turning it on its side and tapping the bottom. Fill the new pot 3/4 full with fresh potting soil. Carefully shake off as much of the soil as you can from the roots of the plant, being careful not to disturb the roots too much, and place the root ball in the new pot. Fill with soil to just below the lip of the pot, tamping the soil around the edges to remove any air pockets. Welcome the roots into their new home by watering with warm water. Then water as needed to keep the soil moist but not too wet.
