Topsoil
Topsoil is the uppermost layer of soil, typically found in the first few inches to several inches or even a foot of the Earth's surface, depending on the location and the specific characteristics of the soil profile. It is the most fertile and biologically active layer of soil and plays a critical role in supporting plant growth and ecosystem function.

What are some common problems I might encounter when growing calla lilies, and how can I address them?
Calla lilies can be susceptible to pests like aphids and spider mites, as well as diseases like bacterial soft rot. Regularly inspect your plants for signs of infestation or disease. If you notice any problems, treat them promptly with insecticidal soap or fungicide, following the instructions on the product label.
Are calla lilies poisonous? What precautions should I take when handling them?
Yes, all parts of the calla lily plant contain calcium oxalate, which may cause severe irritation and swelling in the mouth and throat if ingested. Keep calla lilies away from children and pets, and wear gloves when handling them to avoid skin irritation.
How do I overwinter calla lilies in colder climates?
After the first frost, when the foliage begins to wilt, dig up the rhizomes and allow them to dry in a cool, dry place. Store the rhizomes in a paper bag or cardboard box in a cool (45-50°F or 7-10°C), dry place until the danger of frost has passed in spring.
