Phenology is the study of recurring biological phenomena and their relationship to weather. Bird migration, blooming of wildflowers and trees, are examples of phenological events. We have all observed that plants bloom earlier in warm springs. Insects also emerge earlier when it is warmer than in cooler seasons. Because the development of both plants and insects is temperature dependent, plants can accurately track the environmental factors that determine when insects are active. For this reason, plant phenology can be used to predict insect emergence. Accurate timing of pesticide applications is best for the environment because this can reduce the number of applications required for control.
Most of the weather people are telling us that we are about 20 days ahead of our normal spring temperatures and plant development. This means that many of our spring chores will likely have to be done earlier which would include our dormant spray and application of pre-emergent weed controls including crabgrass control. Remember that these “tools” take a lot of the work out of gardening. Timing is critical and one of “nature’s clocks” is the Forsythia shrub’s bloom time. When you see the yellow flowers it is time to have your pre-emergence weed control products applied to your landscape and lawn. [pre-emergence refers to weeds that sprout from seed i.e.; crabgrass, not be confused with perennial weeds like dandelions and others]
Another important item to take care of right away is testing your garden soils for nutrients and pH if you have not done this for a year or so. Fall is actually a better time to do this but like many of us, that didn’t happen so now is the time. There are a couple of ways to test;
One is to purchase a soil test kit and do it yourself. The problem is that when you get the results..... what do I need to do to make the necessary corrections?
The other approach is to get a Free Lab Kit from your local garden center or nursery and follow the directions for sampling and send your soil to the Lab for analysis and recommendations for correcting any deficiencies. The fee for testing and recommendations is determined by the type of test requested, charges average about $15.00.
Regarding the subject of last week’s comments on mulches: Remember, when you are cleaning up your flower beds to keep the depth of mulch no more than 2”, you may not need to add mulch, just fluff up the mulch that is there. One of the best mulches available that will actually act as a soil conditioner is aged pine bark fines known as Growers Secret Pine Soil Conditioner. Look for this when you are out shopping, it’s a winner.
