When growing Sweet peas in a home greenhouse vertical strings are spaced about 4 inches apart. They are tied with a slip knot to the top wire, given one turn around the 16-inch and 10-inch wires, drawn fairly tight and tied with a slip knot to the bottom wire. It is best to tie a few strings near the center first and work toward the ends. This will tend to keep all the strings fairly tight. But it may be found necessary to go back and tighten some of them.
Between crops the three lower wires and their turnbuckles are unfastened at one end, neatly coiled and tied to the vertical support at the other end. The strings which generally last two seasons are separated into about four groups after being unfastened from the three lower wires and the lower half of each -group is gathered together, tied in a loose knot and allowed to hang from the top wire until wanted again.
Most seed catalogues list a class of sweet pea referred to as Early Flowering. And the description generally states that these varieties “are valuable for winter flowering under glass” or that they are “popular as home greenhouse subjects,” to quote two.
It is this class which I grow in my greenhouse, and the following six are the varieties I have used of late : Joseph, salmon pink; Red Man; crimson; Christmas Triumph, pink and white; Kate Smith, scarlet; White Giant, white; Tahoe, blue.

Recommendations for the successful cultivation of sweet peas
- Pre-soaking the seeds in hot water and piercing the peel for faster germination of the sprout.
- After the appearance of the first sprout, you can immediately plant it in the prepared soil.
- Sweet Peas prefer peaty and loose soil with a neutral level of acidity in the greenhouse.
- From fertilizers it is better to use potash or phosphate, but not nitrogen.
- Do not use fresh manure, the plant may die.
- The best seedling method for sweet peas growing is in separate pots.
- In the open ground, the plant is transplanted with the onset of heat, while the seedlings are extremely sensitive to possible frosts and over-wetting.
- The root system does not like excessive waterlogging, so nearby groundwater can be an obstacle to successful cultivation.
- The plant loves fenced from drafts places with sufficient light.
- The formation of flower arrangements is possible in the presence of closely spaced vertical supports.
- High varieties of sweet peas are necessarily tied with twine.
- If the plant is planted near a fence or wall, props may not be needed.
