Seeds in most cases are best to use when you start gardening when planting many vegetables, herbs, annuals, and some perennial plants.
Not only will the plants do better when planted from seeds directly sowed in the garden, you can also save a substantial amount of money
Packets of seeds that can grow at least 8 plants and up to 100 plants can cost between $2.00- $10.00 while one plant can cost that or more. This will allow you to fill your garden with all the plants you want to grow.
The other side of using seeds is that you can collect many of these seeds from the best plants that you are growing to plant next years garden.
Know the temperatures which your seeds can be planted in the garden for best germination and growth. Soil temperatures are critical to successful germination, it is essential to know your soil temperature before you plant.
Invest in a thermometer to check your soil temperatures.
- Easy-to-read green, yellow, and red tick marks
- 5-inch stainless steel stem penetrates soil
How to check your soil temperature
Use a thermometer that is made to test soil at least 3 inches below the surface of the soil. Seed temperatures need to be taken 3-4 inches down to provide your seeds with the right temperatures to germinate.
Allow the thermometer to sit in the soil at the prescribed depth for at least 1 minute to get a good reading.
Take soil temperatures in the morning to get the coolest temperatures and take 3 consecutive days to see if it fluctuates.
Where to purchase the best seeds
First, if you can use your own seeds you know exactly how good they are going to be, but if you are purchasing them it is best to buy from a reputable seed company.
