Climate signals

Penn State's York County Transplanting Guide labels Last frost in Spring as May 1 and First frost in Fall as October 1.
The Transplanting Guide distinguishes a cold weather plant that can be planted before the last frost or withstand a light fall frost from a warm weather plant.
The table columns include Preferred pH range, Flat temperature in degrees F for Germinating and Growing, and Needs Light or Dark for germination.
The table connects Date to start indoors, Early date to transplant, Latest date to transplant, spacing, Days to maturity, Date of maturity, and Date of last productive harvest.
The guide keeps late planting dates tied to the first fall frost while allowing enough harvest time for repeatedly bearing crops.

Planning notes

Column 6 includes a seven day period in a cold frame to harden the seedlings before setting them in the garden.
Column 7 says season extenders such as heavy row covers and walls-o-water can move early transplant dates a little earlier.
The Latest Date uses the first frost in the Fall and is calculated for a more complete harvest, not just one picking.
The guide says gardeners using an intensive bed method can disregard row-spacing column 10 and use plant spacing for both plant and row spacing.
Broccoli uses Feb 9 indoor start, Apr 6 early transplant, Jun 23 latest transplant, 90 days to maturity, and Jul 5 first maturity.
Brussel Sprouts use Feb 9 indoor start, Apr 6 early transplant, Jun 3 latest transplant, 110 days to maturity, and Jul 25 maturity.
Cabbage, Regular uses Feb 9 indoor start, Apr 6 early transplant, Jul 8 latest transplant, 75 days to maturity, and Jun 20 maturity.
Cauliflower uses Feb 9 indoor start, Apr 6 early transplant, Jul 8 latest transplant, 75 days to maturity, and Jun 20 maturity.
Eggplant uses Mar 12 indoor start, May 21 early transplant, May 29 latest transplant, 90 days to maturity, Aug 19 maturity, and Sep 23 last productive harvest.
Lettuce, Leaf uses Mar 20 indoor start, Apr 24 early transplant, Aug 22 latest transplant, 30 days to maturity, May 24 maturity, and Jul 21 last productive harvest.
Pepper uses Mar 20 indoor start, May 15 early transplant, Jun 13 latest transplant, 75 days to maturity, Jul 29 maturity, and Sep 23 last productive harvest.
Tomato uses Mar 16 indoor start, May 11 early transplant, Jun 13 latest transplant, 75 days to maturity, Jul 25 maturity, and Sep 19 last productive harvest.
Rows marked (1) are best direct-sown or need special transplant precautions, so celery, cucumber, endive and escarole, kale, melons, pumpkin, squash, and Swiss chard stay without priority links.
Asparagus, potatoes, Chinese cabbage, and head lettuce are source rows without priority links because catalog links should be exact crop-row examples.
Use these priority catalog links as crop-row examples, not Penn State cultivar recommendations.
