The timing depends on your last frost date and the specific plant. Most vegetables should be started 4-8 weeks before your last expected frost. Refer to our cheat sheet for specific timing recommendations for each plant type.
Use a sterile, well-draining seed starting mix. Avoid garden soil which can contain pathogens and may compact too much. Good seed starting mixes contain peat moss or coconut coir, perlite or vermiculite, and sometimes compost.
As a general rule, plant seeds at a depth 2-3 times their diameter. Small seeds like lettuce should be planted very shallow (1/8 inch), while larger seeds like beans can be planted deeper (1 inch). Our cheat sheet provides specific depth recommendations for each plant.
Leggy seedlings are usually caused by insufficient light. Ensure seedlings receive 14-16 hours of bright light daily. If using windowsills, supplement with grow lights. Also avoid overcrowding and maintain proper temperature.
Hardening off is the process of gradually acclimating seedlings to outdoor conditions. Start by placing them outside in a sheltered location for 1-2 hours, gradually increasing the time and exposure over 7-10 days. Reduce watering slightly during this period.
