Is it best to start seeds indoors?

While some crops can be direct seeded, you can start them indoors and move up the harvest date.

If you have to wait for outdoor soil to reach the optimal temperature, you'll miss out on growing days.

Should you water seeds right after planting?

You won't have to water after they are planted, preventing seed movement. Create a mini greenhouse by covering the seed tray with a plastic tray or plastic wrap. This will keep the moisture and warmth inside, and you shouldn't have to water again till after the seeds have germinated.

How many seeds do you put in one hole?

Like most things in gardening, there are always exceptions to this rule of 2-3 seeds per hole. If you're planting large seeds like cucumbers, melons, or pumpkins, you should only use one seed per hole.

Where is the best place to start seeds indoors?

Place the seeds in a warm location.

Check the seed packets to understand the ideal soil temperature for each plant. Then place the seed tray in front of a windowsill that receives partial sun, or place the seed kits on a heating mat to maintain an even temperature and light. South-facing windows generally work well.

Is it OK to start seeds outside?

Planting seeds this way is called direct sowing, and it is an easy process that yields great results. Unlike indoor seed starting, direct sowing involves unpredictable elements: weather, wildlife and insects. Even so, many vegetables, annuals, herbs and perennials sprout easily from seed sown directly into garden soil.

Can LED lights be used for seed starting?

For many years, fluorescent shop lights were the go-to seed starting bulbs for gardeners, but LEDs have quickly replaced them as the standard choice. LEDs are usually more expensive than fluorescent bulbs, but they are very energy-efficient and long-lasting.

Should you cover seeds when germinating?

Moisten the newly planted seeds with a mister or a small watering can. To speed germination, cover the pots with plastic wrap or a humidity dome that fits over the seed-starting tray. This helps keep the seeds moist before they germinate.

Should seedlings get 24 hours of LED light?

Seedlings need 14-16 hours of light every single day, without fail. Don't leave them on for 24 hours a day though. Like us, they need to rest at night. So plan to keep your artificial lights on for 14-16 hours during the daytime, and turn them off overnight.

How late is too late to start seeds?

How tall should seedlings be before planting?

Ideally before they're transplanted, seedlings should be at least twice as tall as their starter trays. So, that would be about 3-4″ tall. However, I have planted ones as short as 1″ tall in my garden before with no issues. But, the larger they are, the easier it will be for you.
