There are no big thoughts or great events that will flow in the paragraphs that follow, but hopefully a collection of a few smaller observations from this week that will be a bit helpful.
Several days ago someone brought me a large stem from a lilac bush. An archeologist might have better studied it than someone who grows things in the dirt. It was dead, with lots of insect borings and an ample crop of lichens to prove it.
After cutting out the dead stems the re-growth was not happy. Could it be the lichen growth on the old that was infecting the new growth? That answer is definitely no.
A bit of probing identified that the old bush had been a favorite long time roost for a significant number of regular birds. Doing what birds often do when they sit, I wondered if an accumulation of that had brought the soil to levels that made the plant unhappy, Possible, but I doubt it.
Then it was mentioned that there were white spots on it. That might suggest a good case of scale (a tough insect) that could be a big problem. They seem to like lilacs. A dose or two of horticultural oil or soapy water is about the only attack plan. They resist most insecticides but will succumb to clogged breathing pores from the above treatment.
Now might be a time to mention pruning multi-stemmed shrubs. A great approach is to remove some of the older stems on a regular basis. I can’t think of a single plant that produces stems that have great ornamental value by their seventh birthday. Twig dogwoods have their best winter color on new growth, so stems more than two years old are unappealing.
Another guideline to follow is that if the problem is seen on the new growth, you should look for insects. If it is on the older leaves, it is possibly nutrition or disease.
On the disease front, I was surprised at the slow recovery of the greenness of my lawn. Seems that this is a great weather year for grass fungus. Some suggest that the more fertilizer, more water, more happy the yard, the worse the problem. Mine is none of that and is pretty bad.
Waiting is the best approach to this problem. It will grow out of it when temperatures, moisture and humidity realign to the green grass mode. More water and fertilizer may aggravate the problem. Fungicides seem to have a fleeting influence, so are hardly worth the effort.
Speaking of water, a forceful closing to this sermon is needed. It rained. It rained a lot. We had over five inches and much of it went into the ground. Unless you had a whole lot less, and I doubt it, I offer the following.
If you have picked up the water hose since it rained you are watering way too much. I’m even still looking for a container that needs water. Right now, two or three days after the last storm, the emphasis is still on observation. Container watering may begin again later today or tomorrow.
In my vegetable garden the water is off and will remain off for a long time, hopefully the rest of the growing season. Now the attention is to the bounty of the harvest and the weeds that are trying to thrive with the newfound moisture. Right now a chunk of the garden’s first cantaloupe is waiting on the kitchen table. See you!
