Seed Choice and Timing

Taking time to research what vegetables you want to grow is essential to a successful garden. It provides you information like planting time, harvest time, and, sometimes, even feeding schedules.

It's best to understand the length of your growing season before purchasing seeds. First, be sure to check the information on the plants you aim to germinate. There are often planting windows where the producer provides a set number of weeks to seed before the last frost. You may also find information about how long the plant takes to produce table ready food. Take this information and ensure your season is long enough to grow and develop a worthwhile crop of the fruits and vegetables you chose. Some plants will simply not produce in certain climates, and it's best to know which ones work for you before you buy your seeds. 

Every plant is different, and, as such, growing time varies. You will find that a typical growing period from seed to ready-to-plant seedling is three to six weeks. This period is necessary to grow a hearty plant ready for outdoors.

Also, see if the plants you plan on growing from seed prefer outdoor germination or "direct sow." Some simply have trouble starting inside and have better chances in the ground. For these, you will need to follow the plant-specific instructions for seeding and germination. Typically, you can seed cold-hardy plants in late winter or early spring, while heat-loving plants are in mid-to-late spring. Some plants even prefer fall planting for a spring crop. Again, check the length of your growing season to guarantee enough time for a proper harvest.

Sowing Your Seeds

Now that you have prepared your containers with your growing medium, it's the perfect time to sow the seeds. The packet that you received your plants will often have recommendations for how deep to sow. A standard measurement in planting is a depth of two to four times the diameter of the seed. But as with everything, this is not always true. Some seeds prefer to grow on top of the medium and not buried. Confirm individual seed planting depths before sowing. 

Ideally, when starting from seed, there can be between one and three seeds per cell (if starting in a tray) or small container. Multiple seeds act as a redundancy if one fails. This planting method is standard and often determined by germination rate or the percentage of successfully germinated seeds under proper growing conditions. If multiple seeds sprout in a cell, as the plants mature, you can clip the weaker of the seedlings and leave the heartiest. After sowing in the seeds, add a thin layer of vermiculite atop the medium. This layer acts as a secure barrier for the tender seedlings to push through.

At this point, your seeds are well on their way towards becoming seedlings and eventually hearty plants to produce for your home. What's next? In my next article, I will be looking at the seedling stage and how to monitor the success of your developing plants. After that, we will finish up the series with a final article on the care of mature plants.
