Starting vegetables from seed is an inexpensive way to grow seedlings for your summer garden. Most vegetable plants are grown from seed first planted indoors then later transplanted out to the garden bed. Indoor seed-starting allows you to start the plants earlier in the season while also giving you control over watering and other conditions to ensure a healthy start to the plants. Proper irrigation is vital, otherwise the seeds may not germinate or the young seedlings may be more prone to disease and death.
Soak the potting mixture with water after placing it into the pots. Water from the top until the water drains freely into the drip tray. Leave the water in the drip tray overnight so the soil can soak up as much as possible before seeding, then empty any excess water from the trays in the morning.
Sow the seeds into the moist potting soil at the depth recommended on the seed packet. Mist the soil surface with a spray bottle if it begins to dry out.
Cover the pots with a plastic bag once they are seeded. The plastic bag helps retain the moisture in the soil during germination, so that you do not need to water and disturb the seeds until after they have sprouted.
Remove the plastic bag once the seedlings emerge. Water the seedlings by filling the drip tray with water and allowing the pots to soak in it until the soil surface becomes moist.
