Snow peas don't usually need additional fertilization after planting, notes Utah State University Cooperative Extension. If you suspect nitrogen deficiency, purchase a soil-testing kit from a garden shop and test your soil. If the test confirms low soil nitrogen, work small amounts of nitrogen-containing fertilizer into the soil.
Don't overfertilize, however; too much nitrogen reduces the number of pods you will harvest. Root rot from fungi infection is a common pea plant problem. Root rot destroys the plant roots, but the first symptom you might see is leaf yellowing. Pythium ultimum is a common fungal cause of root rot in low-lying or damp soil. If your plants appear stunted and the leaves turn pale yellow, try pulling up a plant.
Plants must have soil with excellent drainage and full sun to partial shade. Sufficient spacing of plants for good air circulation is important, too, because sweet peas are susceptible to mildew.
Young seedlings must also be protected from slugs, snails, and marauding birds until they are 4 to 5 inches tall. How do you make sweet peas last longer? Fresh cut sweet peas last longer if they are conditioned immediately after cutting. Cut the stems 1 to 2 inches above the original cut while holding them underwater to prevent air bubbles that can block the flow of water in up the stem.
Should I pinch out my sweet peas? To pinch sweet pea plants, wait until they are 4 to 8 inches high. Pinching out sweet peas will provide you with more blooms for cutting. It's one of the wonders of growing these delightful vines. The more blooms you cut, the more will grow, so don't be afraid of pinching out your sweet peas to enjoy the bouquets.
How much sunlight do peas need? Like all green plants, peas require light energy to grow. While this member of the legume family can make do with partial shade, for the best yield choose a planting area that receives full sun six to eight hours daily.
How do you get sweet peas to flower? Harden seedlings off for at least a week, and then set them out into the garden as soon as the soil can be worked. Gently shake the plant at the stalk to release more pollen, and help speed the process along.
Peas are a cool-weather crop. Pea seeds can survive a small amount of frost a few days at a time but ultimately are not considered frost-tolerant plants. Aphids are a small insect that can infect your pea plants. Pea aphids feed on your plants and inject the plant tissues with a toxin that causes the plant to slow its growth and reduce its pea production. Signs to look for when looking for aphids on your plants include stunted growth, small leaves, wilting stems, and physical presence of the bugs.
Extreme aphid infections will cause your plant to wilt and die. They also leave a sticky honeydew residue when they feed, and this attracts sooty mildew.
There are many defenses against aphids. Some natural defenses include using aphid predators to rid your crop of the smaller insects. Ladybugs are famous for their welcome presence in gardens, and this is because of their ability to eradicate crops from annoying pests such as aphids. Other bugs, like the big-eyed bug and damsel bug, may also be introduced into the garden to help keep aphids at bay.
Very light aphid infestations can be solved by simply washing off your plant and physically displacing the aphids. A generous watering with a powerful garden hose may be all you need to get rid of these pests. If you have a massive aphid infestation on your pea plants, then you can look at using some insecticidal controls. The most popular of these being Neem oil , as it is safe to use on organic crops, and does not harm valuable bugs like bees. Other, more intense insecticides are not encouraged on your home crops.
Pea plants that are not receiving enough water, or are not getting watered thoroughly enough will show physical signs of upset. These plants will often droop and appear tired and wilted. The solution is easy: water your plants thoroughly as soon as possible. If it is dry to the touch and dry and inch or so down into the soil, they are ready for a drink. You should try and water your plants in the morning.
The cooler morning temperatures will limit the amount of water lost to evaporation on the hot soil. It will also give the water the chance to saturate the soil fully before being heated up by the sun. The early morning watering also means that your plants will have the proper hydration to deal with the sunny day ahead. When watering, make sure to apply the water on the root systems, not the leaves of the plant.
It is the root systems that need the water, not the leaves. Additionally, true wilt displays downward curled leaves and flattened pea pods. Common wilt displays black, expanding cankers on stems. True wilt damage of pea plants includes stunted growth and ruined feeder roots. Plants may die through a very quick or slow process; pea plants kept in dry soil die at a faster rate than those in moist soil types.
Common wilt damage includes malformed seedlings that quickly die, stunted growth, ruined roots and death. Common wilt causes a slow death in pea plants.
