I planted a sunflower seedling at an Earth Day event at my university, but I forgot when to transfer it outdoors. It's been over a month and it's about 6 inches tall, but the stem isn't very sturdy yet. When would be the best time to plant it in the ground?

You could totally run a little experiment! After hardening off your sunflower, try planting it outside and at the same time, sow a couple of seeds directly into the ground. This way, you can see which method yields a stronger plant. Just a heads up—critters love seedlings, so you might want to protect your plant with a cut-up plastic bottle over it at night.
I say go for it and plant that sunflower! Just make sure to plant it deep and mound some extra dirt around the stem to give it support. It might look a bit leggy right now, but with some watering and care, it should strengthen up in no time!
First off, consider where your seedling is now. If it's indoors, it might not be getting enough light, which can make the stem weak. Start by introducing it to outdoor conditions gradually—leave it outside for a few hours each day to help it acclimate. You should wait until the nighttime temperatures are consistently above 45°F before planting it outside. Also, remember to cut the bottoms of those cups; they might not decompose fast enough for the roots to get out!
I totally get the concern about transplanting! I've had great success with moving my sunflowers despite not being able to direct sow them because of squirrels. They always end up thriving and growing tall, so don’t stress too much about transplanting!
