Touch Base with Your Tillandsias

TillandsiasYou don’t have to strike out with Tillandsias.  These epiphytes stand out in many shapes, sizes and psychedelic colors.  My local nursery tells me they are a big favorite of the people living in all the new developments in the area because they can grow indoors so easily.   DispIay them creatively: glue a cluster of them to a piece of wood or a single one onto a small piece of driftwood, pop one in a teacup or hang them in various houseplants.

The best location to keep them is in a room with bright, filtered light.  I had a cluster of them for many years playing hardball and refusing to bloom.  I started experimenting with putting a small one outside in the summer hanging on a nail on my east-facing front porch.  It received some early morning sun (on the days the sun came out.)  Otherwise, it just got a good dose of bright light.

Cedar Flagging

Cedar flagging is a natural process that is often confused with a disease.  Evergreen plants, including conifers and broad leaf types, naturally shed some old foliage each year. Stress factors, such as insufficient water, hot winds, construction damage or other root disturbance, poor planting procedures, or recent planting can promote flagging.  It is being seen more often this year because it is more common when there is hot weather followed by cold weather.

Spring is a good time to divide established plants, and many herbaceous perennials need to be divided every few years anyway to stay healthy.

Plan to dig on a cool morning, preferably one with cloud cover – not too hard around here.  Learn about:

  • Dividing Fibrous-rooted Plants
  • Dividing Fleshy or Woody Crowned Plants
  • Dividing Suckers from Plants
  • Dividing Plants with Rhizomes
  • Dividing Plant with Tubers
