Keep on seeding. Keep on planting. Think ahead. A lot of seed packets will have days to maturity. That’s not always accurate in less than ideal conditions (I.e. too much shade, cold, poor soil). So, we need to plan ahead. Maybe it’s starting seeds inside for faster germination then transplanting for a jump start.
I may have enough lettuce today but what happens when the lettuce turns bitter or goes to seed? I need to wait another three weeks before greens. That’s why it’s important to sow successively (sowing seeds every few weeks). Learn your soil, your conditions/seasons, your taste preferences to help guide you in staying stocked with seeds and having vegetables to eat when you want.
One biggest piece of advice is to plant what you eat or learn to cook with the veggies you’re growing. If you don’t do this, you’ll end up with piles of veggies that take up space and aren’t utilized.
