2	Pansy, Ice Pansies		Yes		6 weeks before last frost (Feb 24 50%)	Nov-25	Surface, barely covered with 1/16" soil	65-70°F	10-14	Almost none until germination. As soon as seedlings emerge, provide plenty of light: 3-4" beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night.	Moist until germination, then prefer to dry out between waterings.	Garden	Baker Creek Seeds (2017)
3	Hosta Newest Hybrids Mix		4 weeks cold/wet	11/25/2019 (started 11/29)		Dec-27	Press into soil, barely cover. Only use sterile seed starting mix (not DIY blend).	60°F	14-21	Sow the hosta seeds in quart-sized plastic plant pots. Use a bagged potting mix for seedlings. Fill each pot nearly full with potting mix and press it down lightly. Then scatter seeds over the top, add another sprinkling of potting mix to cover the seeds, and place the soil-filled pots in trays of water until the soil surface is thoroughly damp. Let each pot drain for several minutes, seal it in a large plastic bag, and put it a warmish place. Check the pots every few days for signs of germination, and usually within two weeks there will be some seedlings starting to pop up out of the soil.	Never let them dry out from the minute you plant the seed until the time you plant them out. They need a constant supply of water to keep them growing healthy.
