I can show you how to grow peas because they are my favorite vegetable, bar none. So I made you a video about it, watch and let me know your thoughts.
How to grow peas, what you need to know:
Peas like cool weather, when the summer starts to heat up, they wilt quickly. So its key to get the seeds starting quick. You have two choices, seed directly in the garden, or start them in seed starting trays or pots. Both have advantages.
I now prefer to start pea seeds in pots and transplant them outside. I have found that the seeds germinate faster and better than seeding them directly. A big reason is that the soil outside is cold, and the seed starting mix is warm, because its inside. Took me awhile to figure that out. I also direct seed a bit when the weather starts to warm up, as a back up measure.
Have the bottom of your trellis right where the plants are. Peas start to climb right away, or else they will fall over. You can set some small sticks alongside the plants to lead them to the trellis above, if need be.
I do not have any problems with insects or diseases with my peas. I mainly plant sugar snap peas and snow peas. Many of them don't make it out of the garden, we and the Labs eat them standing there in the garden.
You can shade the pea plants to keep them growing a bit longer, but I have not had much success with this. Part of the problem is the trellis is quite high. There are some pea varieties that don't grow as tall, you could try those.
When the sugar snap peas start to fade, I plant string beans below the trellis, and leave the fading peas on the trellis. The beans will climb up and work just fine. This way you have used the trellis for two plants in one season. Nice.
