How many seeds of each herb did you purchase? You will most certainly be much more successful starting in the spring. But, if you have plenty of seeds, why not try a few this fall. I keep a small fall herb garden in several strawberry pots. Below is culture info for my area (Houston) that I have learned over the years.
Greek oregano: keep this away from taller plants; doesn’t like it too hot or too cold; depending on variety, can be (and usually is) invasive. Better if started from established nursery seedlings or divisions off of other plants.
Coriander/cilantro: does not like the heat and will bolt once established if too hot; plant seeds in Oct - Nov and let go to seed in spring will self seed and reappear in fall as small plants which can be transplanted.
Parsley (single Italian): does not like heat at all and will go to seed easily around May in our area. Seed stores 2 to 3 years. Ideal sprouting temp 75 degrees; grows best 60-65 degrees.
Fernleaf dill: likes cool weather; plant in fall. Readily self-seeds. Great for attracting beneficial insects.
Rosemary: best grown from cuttings or transplants. You can root branches by bending them down and putting soil over the
middle.
Chive: Grown year-round here; harvest frequently for continued success.
Sweet basil: prime harvest dates are June - Nov; loves full sun and steady irrigation. Cut flower stalks before they go to seed to maintain full flavor of leaves.
Spearmint: Very invasive; best if started from divided plants. Will die back in very ocld weather and without irrigation in dry hot weather. But never fear it will come back. Unless you have a spare 40 acres I recommend keeping this one in a pot.
Strawberry: You’re right; it should be interesting. I’ve always had a heck of a time with strawberrys here.
Catnip: If you have any cats in the neighborhood, don’t expect your catnip to last too long. LOL If kittys aren’t a problem then it can become invasive. Prefers sandy soil; full or partial sun. Seeds should do well as a start but will do better if started in spring.
Marigold: I’m assuming you’re talking about Mexican Marigold (if not disregard) Thrives far better in full sun. I would start seeds indoors this winter and plant seedlings early spring.
Moonflower: No advice on this one as I haven’t grown this.
Lavender: What variety did you purchase? Some lavenders are very difficult to grow here due to our heat/humidity. All need full sun, sandy well-drained soil, and a raised bed to improve drainage (they don’t like wet feet). Depending on variety, seed propagation can be successful if started indoors during winter and transplants are set out once last frost date has passed.
I hope this helps a bit. Good luck!
