Considering that some of the winter squash can last right through winter and into spring, there really is a squash for every season. By the time the last of the winter squash run out, the first of the summer squash will be ready later in spring. They get an early start here, and continue until frost. By that time, the earliest of the winter squash will be ready for autumn, and will last through winter.
However, they all get planted about now. There is no such thing as cool season squash. They are all warm season vegetables (actually fruits). The vines and foliage all grow like weeds while the weather is warm, and then succumb to frost at the end of their season. They all grow very easily from seed, but because each garden needs only a few plants, they are often planted as seedlings.
The main difference between summer and winter squash is that summer squash plants continue to produce many smaller fruits while the weather is warm, and winter squash plants produce only a few larger and firmer fruits that develop slowly while the weather is warm, and then finish ripening as the vines that produce them die in autumn and winter. One begins where the other finishes.
Zucchini is the most familiar summer squash here. It is most productive if regularly deprived of its tender juvenile fruit, and is notably less productive if the fruit is allowed to get bigger and tougher. Pumpkin is the most familiar winter squash here. It is expected to produce only a few big and firm fruit that take all season to develop. Extra juvenile fruit may get plucked to favor one or two fruits.
Summer squash deserve more prominent locations in the garden because the fruit gets harvested regularly. Zucchini grows as a large plant, but stays somewhat confined. Winter squash want the same sort of rich garden soil and watering, but can be put out of the way. Except for plucking a few extra fruit, not much more needs to be done to them. Some like to climb fences. Pumpkin vines can be directed to the edge or just outside of the garden.
The calendar does not always agree with the weather. It really is about time to start replacing aging cool season vegetable plants with fresh new warm season vegetable plants. Earlier warm and dry weather had suggested that it was getting late. More recent frosty weather followed by rain suggested otherwise. Regardless, there is no point in arguing with what the calendar determines.
Isn’t this a delightful meadow? It is located right across from the historic Felton Covered Bridge
Apparently, someone thought that there might possibly be the remote chance of the potential for homeless people to maybe engage in activities that could perhaps be determined to be bad, right behind the Community Garden. If you look closely, you might be able to see them back there. Maybe not. (More accurate information can be found at the Facebook page of Felton League at 
Just a few feet downhill from where the old valley oak had lived for centuries (
There are not many things that will grow in my zone that I will not at least try to grow if I have the space and resources to do so. I really like to grow fruits and vegetables, particularly those that I am familiar with from when I was young. They are just as productive now as they were then. The only problem is that I do not know how to cook. I can freeze, can or pickle large quantities of produce, but cooking is something that I leave to experts.
Certain fruits and vegetables were so much more palatable before studying botany. Knowing what they really are sort of puts a damper on things.
Somewhere in the San Lorenzo Valley, there is a little old lady who is stitching a blue quilt. It is made of all the blue ribbons that she wins every year at the Jelly and Jam Contest of the Santa Cruz Mountains Harvest Festival. I do not know who she is, but I recognize her squiggly writing on the fancy labels. It is barely legible. Her hands are worn and tired from three quarters of a century off picking fruit, processing it into jelly and jam, and then stitching all her blue ribbons together. She probably giggles as she works, and thinks about everyone who wins only red or white ribbons.
