Watch those heating pads!
If you use a heating pad for starting seeds, you need to keep a watch at the temperature of the soil. I measured over 90F in the center of the tray and over 84F at the corners. This is with the plastic dome on and the shop lights switched on. I used a “instant read” type meat thermometer from the kitchen drawers 😉 Of course this temperature is too hot and this is probably why my impatiens seeds are not germinating.

Bad luck with Impatiens
Looks like it is going to be last last year again. 🙁 Well it has been 20 days since I planted a batch of seeds. It has the bottom heater, lights, dome, everything they need……….still out of the the 72 “coins” nothing has sprouted….not even one! I guess I should check the temperature with a thermometer. I bet they are too warm. check out an update which I posted later

Planted more seeds today
Planted these annuals today: Marigold Shasta Daisy [10-20 days] Snapdragon [7-30 days] Petunia Horizon Yellow [7-21 days] Petunia Dolcissima Fragolino [7-21 days] Petunia Wave Hybrid [7-21 days] These were planted peat ‘coins’ and with a heater mat under them. The whole thing is a Jiffy greenhouse pro.

Starting annuals from seed
So yesterday night, I started planting some of the seeds. I know it is a little too late now. The frost date in my area is around the end of April. Here is a quick online tool to find out your frost date. So from today we have around 7 weeks left. I have planted: Petunia Shock wave Red [7-21 days] Impatiens Accent White Hybrid Impatiens pink [seeds harvested from our neighbor] Impatiens Shady Lady Tango [orange] Impatiens Accent Red Hybrid Pentas New Look Mix They say that we should start them 8-10 weeks before last frost. Hence should have planted around Feb 15th. These seeds were bought from Park Seed.
