Poisonous Plants

As we approach the holidays, there are a lot of questions on poisonous plants. Fortunately, many of these plants have a very bitter taste that limits the amount of the plant eaten. Poinsettia and mistletoe should be kept away from curious children, but the list includes other flowers and plants such as azaleas, calla lily, carnation, daffodil, foxglove, hydrangeas, iris, lantana, narcissus, poppy, sweet pea and tulips. Different parts of the plant may be toxic. Chapter 21 of the California Master Gardener Handbook contains more detailed information as does this poison plant website.

Citrus Bud Mite

Have you ever seen weirdly shaped lemons or oranges that appear to have 'fingers'? The Citrus Bud Mite attacks newly forming flowers and fruits. The mite is only visible with a magnifying glass and has a elongated yellow body with four legs that appear to come out of its head. The mites feed inside the buds, killing them or causing a rosette-like growth of the subsequent foliage and distortion of flowers and fruit. The problem is usually limited to just a few fruit on the tree. Previously recommended oil sprays have not proven effective. This is one of those pests that is best left alone. The oddly-shaped fruit is edible.
