Monthly Q & A by John Stephens
Q: When I had my black walnut tree pruned last month, sap flowed freely from the wounds. What danger does this pose for my tree?
Q: My hyacinths have begun to emerge. What action should I take?
Q: I’m looking for indoor plants, which offer constant bloom. Can you help?
Q: I’m planning my garden for next season. Is lunaria considered seriously invasive in this area?
Q: Do camellias ever flower when planted outdoors in the St. Louis area?
A: Yes, indeed, new cultivars, which seem hardy when grown in protected spots so long as temperatures do not fall below 0°F, have been introduced. Several such camellias were flowering or in full bud in gardens at the Kemper Center for Home Gardening on January 10, 2012.
Q: What could have caused several of our arborvitaes to lose most of their bottom foliage up to heights of about four feet?
A: Assuming that your plants have appeared healthy up to this point, browsing deer may be likely culprits. Some of these animals appear to have a fondness for the foliage and twigs of this evergreen species, Thuja occidentalis, even when alternate feed is available. Do not expect the damaged trees to recover by filling in affected areas, so consider replacement and possible use of repellents.
