Bachelor buttons

They are doing well but not lush. I suspect that is due to my less than green thumb. Along the same vein, the spinach I ordered didn’t yield anything to speak of. My learning curve for the peppers and tomatoes was steep. They didn’t get an early enough start and currently are about 4” tall. I’ve got some left and will start them at a more appropriate date next year. Live and learn!! Thanks for asking and stay healthy! mary

The seeds germinated quickly and were as labeled on the packet. Pinetree Seeds came through for me and they kept me informed about COVID related delays. The seeds were fresh and good quality so that the delayed plantings were offset by the fast germination. I would definitely order from Pinetree Seeds again. They have consistently good selection and quality.

Seeds germinated on schedule about 95% germination rate. About 4" tall right now and nice looking plant.
