How to grow sweet peas from seed:   Sweet peas have large seeds that are easy to manage.
Most varieties germinate readily,  therefore,  if you want to grow flowers from seed,  start with sweet peas.  The blooms of sweet peas are gorgeous and also sweet scented.

Pick a range of varieties 
When choosing,   read the seed packets to find varieties that bloom early , that is, short day,  and late,  long day. Although most sweet peas are annuals,  you can also get perennial sweet peas,  namely Lathyrus latifolia.

Sweet peas come in a huge array of colors and patterns.  Most will grow to 5 or 6 feet,  but there are shorter varieties, which are the bush type,  that will also do well in containers.

To extend the blooming season, choose a few different types.

Start planting early
Sweet peas,  Lathyrus odoratus,   thrive in cool temperatures.   It is important to get them blooming early,  before summer heat knocks them out.   You can plant them outdoors,   as soon as the soil can be worked in spring.   Chances are,  it will still be quite cold,  but the seeds will be fine.   Gardeners in the south,  can start sweet peas in late fall for bloom in late winter or early spring.  Check with your local nursery for best practice in your area.

To ensure the longest-possible season of bloom,  start your peas indoors.

Prepare the seed
It is a good idea to break ,  or soften the hard seed coat before planting,   whether you are planting indoors or out.   This can be done by soaking the seeds overnight in water,   or nicking the brown coating with a nail clippers or a piece of sandpaper.

If you start your seeds indoors,  use biodegradable pots,   such as cow pots,   homemade paper post,   or peat pots.   The seedlings resent root disturbance,   so it is best to have a pot that can go in the ground right along with your transplants.

Use a trellis
Making sure you will have protection from any harsh afternoon sun,   plant your seedlings 6 inches apart,   in a mild morning sun.   Your sweet peas need strings or some form of trellis to climb,  unless you are planting the bush type sweet pea.

Sweet peas use tendrils to climb.  The best from of trellis must be thin enough for the tendrils to grip.  They can grasp anything that is a quarter inch or less.   Netting also works well,  provided the holes in the netting are half to 1 inch wide.  Use nearly invisible netting or biodegradable netting.   Mulch the soil surface to help keep the roots cool.  Water, if rainfall is insufficient and fertilize every 15 days or so with a liquid fertilizer.

Sweet peas need frequent picking
Cut the flowers frequently and remove the faded blossoms,  to keep the vine productive.   It is normal that, once summer heat arrives your vine might turn brown and die.

At that point,  you can pull it out and replant with something else.   The varieties that can tolerate heat better than others,  are the Starry Night and Cupani’s Original.  Check for these brands on your seed packets when at first you purchase.

Enjoy the beauty and sweet scent of the sweet peas.
