Question
QUESTION: I have planted a dwarf astilbe plant in a sunny place for 3 years now, but it keeps dying.  I have decided to give up on that plant, but would like another plant to put in it's place that is about the same size and shape.  What do you suggest?

ANSWER: Hi Mona,
Thanx for your question.  Astilbes prefer semi-shade and moist, slightly acidic soil.  A sunny location is probably too hot and dry for them.  You should try heuchera (hyoo-ker-uh) or coral bells.  This plant is about the same size, comes in many different colors and patterns of foliage and has delicate coral bell blooms.  You can find them easily at most nurseries and the Big Box DIYs.  I hope this helps.

QUESTION: I will pick up some coral bells, but would you please give me some instuctions on how to care for them?  How often should I water them, how deep should I plant them, and any other information you think will be helpful.  Thank you so much.  I am so glad that I found someone who can answer my questions!!

Answer
Hi Mona,
Thanx for your question.  Heuchera/Coral Bells will grow in shade, partial shade and full sun.  When growing in full sun, make sure they are planted in an area with average to rich soil that is well drained and not soggy.  If you don't have regular rain, water them once a week (a good soaking will do).  We had clay soil and they did just fine with no extra care but you may want to side dress them with composted cow manure.  When you plant them make the hole a little deeper than the pot in which they came.  I like to break up the soil and loosen the roots and gently position the root ball in the hole, put a little compost in the bottom of the hole and then the plant and then cover with soil and then soak with water.  They are pretty easy to grow.  Every three years, dig the plant up and cut the root ball in fourths and replant in separate areas otherwise, as the plant gets older the center becomes woody and unsightly as it dies from the center and continues to grow outwardly.  There are many different foliage colors and even bloom colors and the plant is widely availble across the U.S. and Canada.  I hope this helps.
