Hi everyone, I am new to this forum. Thank you in advance for your help. I am a hobby gardener and have been expanding my gardening projects lately. I typically start plants indoors and move them outside when it's warm enough (I live in New Jersey). This year I planted several seeds directly into the garden box plantar I built (I might show design and photos later in the relevant topic). I planted the following seeds: Marigold, Broccoli, Spinach, Soy, "mixed greens" and Kale. It has been about 3 weeks. Only two kale have sprouted. Nothing else. It was an unusually cold spring here and we even had snow 2 weeks ago. It just started warming up. So, I'm wondering, do I wait longer to see if those seeds will start sprouting now, or do I replant the seeds? If I replant, should I try to remove the old ones? Thanks for your help!
