To ensure that your seedlings have the best chance for success, you may want to start them indoors. This post will explain some seed starting basics, as well as lots of ideas to maker your own seed starter pots!

When Should You Start Seeds Indoors?

The first step in figuring out a planting date is to check the directions on your seed packets. The instructions are often vague, but they will usually at least give a general timeline and whether seeds need to be started indoors. Some plants should actually be direct-sown in the ground, carrots for example.

If there are no specific dates on your seed packets, a general rule of thumb is to start indoors about 6-8 weeks before the last frost. The exact date will vary based on where you live and your growing zone. Learn more about growing zones and starting a garden here.

If you start your seeds too early, or they don’t get enough light, they may become “leggy.” This means that they grow long, thin stems that end up being unable to support their weight. Leggy seedlings are not necessarily doomed, but they may not survive.

On the other hand, seeds that are started too late may not have time to grow big enough to go in the ground at their ideal planting time. Again, they may survive, but may struggle with weather conditions.

I use a garden planner to keep track of the different planting dates, germination dates, etc. for my seeds. Using a planner also allows me to take notes of what worked, what didn’t, and what happened with each planting. A big part of gardening is trial and error and learning from year to year.

Are Grow Lights or Sunlight Best?

If you have a good source of natural sunlight in your home, that should be sufficient. However, if there isn’t a place in your home that gets direct sunlight, then grow lights are a useful alternative.

For example, our house has a wrap-around porch, which only allows indirect sunlight into our home. This is great for us because it helps lower our energy usage in Texas’ hot summer. However, it does not provide enough light for my seedlings.

To make sure that my seedlings got enough light to grow, I used small grow lights with good success.

Here’s what I use for seed starting indoors:

  • Indoor Grow Light — This little gem was affordable and is working great!
  • Seed Starting Trays — I opted for plastic versus compostable so I can reuse them next season. Also, I found that starting seeds in compostable trays or egg cartons made them more susceptible to mold.

How Often Should I Water Seed Starters?

Seedlings usually need watered about once a day. However, it’s not about a set watering schedule, but rather the condition of the soil. The soil should stay moist, but not soaking wet.

If you’re using a plastic cover for your seed tray, this can help keep the soil damp and reduce the need for watering as often.

On the flip side, when you start moving seedling pots outside for part of the day to “harden” them off, direct sunlight, wind, etc. can dry out the soil faster.

What Can I Use as a Seed Starter?

You don’t necessarily need to buy seed trays for your seed-starting project!

There are lots of DIY ways to start seeds indoors and many involve recycling, upcycing, etc. supplies that you already have on hand at home.

Not only are these ideas thrifty, but they are environmentally friendly too! (I do reuse my seed trays though!)
