Defoliation is the colorful beginning. It indicates that the weather is getting progressively cooler. It then gets messy with the first rain. This is inevitable at this time of year. After all, it is late autumn. Storms will become more frequent as weather simultaneously becomes cooler. So, while gardens are getting wetter, they also take longer to dry between storms.
Ironically, vegetation uses much less moisture while it is so abundant. Deciduous foliage can not perform any evapotranspiration after it defoliates. Evergreen foliage is much less vascularly active while cool. Roots can not utilize all the moisture that autumn and winter rain provides. Soil in some areas might stay moist from now until next spring or summer.
Conversely, summery weather is innately arid and warm. That is how the Mediterranean climate here operates. Moisture is either scarce or abundant. Rain will eventually stop in spring, and then not resume until next autumn. Summer thundershowers are uncommon. Gardening could likely be easier with a bit less rain for winter, and a bit more for summer.
Rain will become more frequent through winter.
With more rain expected, irrigation needs seasonal adjustment. Such adjustments might need to be incremental, since weather changes incrementally. Manual irrigation might be either less frequent or less voluminous, or both. The same applies to automatic systems, which have a disabling ‘rain’ option. It turns irrigation off without modifying the schedule.
Besides necessitating modification of irrigation, rain can also be messy. It dislodges and accelerates the deterioration of defoliating deciduous foliage. It causes even formerly dry soil to become muddy. A bit too much rain can cause erosion. Cleaning up such mess is less pleasurable while the weather is wet and cool. Then, the weather gets messy again.
Rain can not postpone all gardening. Spring bulbs must get into their garden soil prior to winter chill. Dormant pruning happens later in winter, prior to spring. Fortunately though, gardening is less involved than it is during spring and summer. Maintenance of tools and sorting seed can be indoor tasks for rainy days. So is shopping online for seed, plants or garden tools.
Highlight: Freeman Maple
It combines the autumn foliar color of red maple with the lacier foliar form of silver maple. Freeman maple, Acer X freemanii, is a hybrid of the two. It occurs naturally where ranges of its parents overlap. However, most modern garden cultivars are products of intentional hybridization. Like silver maple, it does not need much chill to exhibit autumn foliar color.
Freeman maple inherits other attributes from both its parents. It combines rapid growth of silver maple with structural integrity of red maple. Although it gets bigger than red maple, it is not as imposing as silver maple. It develops high branches like silver maple, but also is symmetrical like red maple. Big roots are about as complaisant as those of red maple.
Mature Freeman maple trees can grow about forty feet tall and broad. Autumn foliar color is vivid orange and red, and lasts longer than that of red maple. Since Freeman maple is a hybrid, it is mostly sterile. It can not generate an annoying abundance of seed. Nor can it naturalize in favorable climates. It is an exemplary maple for mild climates such as this.
