When To Plant Sweet Peas In San Diego

Mixed Royal Family Any garden space will be transformed into a kaleidoscope of color and smell by the gorgeous array of heirloom sweet pea types in Sweet Pea. Due to their powerful smell and excellent cutting qualities, we adore sweet peas. They will cheerfully reseed and produce years of lovely blooms whether they are grown on a trellis or allowed to grow wild in the garden.

  • In Zones 9 and 10, sweet peas are a cool-season crop. They can be planted from late fall to early spring. Sweet peas take a while to bloom; for the most breathtaking early spring blooms, we advise planting them in October or November.
  • Direct sow in the early spring when there is no risk of frost and the soil is workable.
  • You can direct seed sweet peas in full light in Zones 9 and 10 or move them outside. To protect plants from the heat and Santa Ana winds during our hot fall season, we frequently start in starter trays. We perform transplanting while covered by shade cloth into deeply irrigated soils.
  • In order to direct sow, seeds should be planted in thoroughly cultivated, debris-free soil. Add half of the finely sifted soil on top.
  • Plant seeds into thoroughly moist, top-notch seed starting soil if you’re planting them in starter pots. After scattering the seeds over the surface, cover with half of the finely sifted soil.
  • Apply an organic liquid fertilizer once your seeds have germinated and grown to a height of 1-2 inches. You can plant the seeds outside in the garden once they are 3–4 tall.
  • Plants should be at least six apart.
  • Once you have them established, this plant is simple to grow! As they develop, they will require assistance, such as a trellis, to climb.
  • Mulching extensively around your plants will enhance moisture retention and weed control.
  • Early in the morning, gather the flowers, and immediately put them in a vase with room temperature water. Blooms have an overpoweringly fragrant perfume that permeates the entire space.
  • It’s simple to grow this bloom in a container. Make sure your container is at least 20 inches deep, and don’t forget to include support so that plants can flourish. Remember that because they have more surface area and less soil to absorb moisture, containers will dry out more quickly. To prevent the soil from drying out or becoming too hot, cover the top layer of soil in the container with a thick layer of mulch.
  • It is crucial to safeguard plants from hot weather or heat waves. If required, cover with shade cloth.
  • To prevent the soil from drying out or becoming too hot, cover your plants with a thick layer of mulch.
  • When planting sweet peas in the fall, aphids may be a problem because of the heat. As soon as you notice any aphids on your plants, wash them off and wait until the soil has cooled.
  • Because it grows slowly and is so adorable, we like to place alyssum at the foot of the sweet pea plants.

when to plant sweet peas

When between October and April, plant sweet pea seeds. Aim for late October or late November or late February or early March for the best outcomes because midwinter temperatures and light conditions aren’t the optimum. In April or May, sweet peas can also be planted directly into the ground. During a moderate period between March and May, sow your sweet pea seeds and plants.

When should Californians plant sweet peas?

Annual climbing vines with a cool-season growth period, sweet peas (Lathyrus odoratus) can grow up to 6 feet in height. They are prized for their delightfully fragrant, fluttery blooms, which are available in a variety of shapes and colors thanks to centuries of selective breeding, including bicolored, streaked, and picoted varieties. The late 1600s saw the introduction of sweet peas to the world by Sicilian monk and gardener Francisco Cupani. Modern advancements have boosted disease resistance, lengthened bloom durations, increased adaptability, and given gardeners throughout the world access to a wider variety of colors, sizes, and forms, continuing the fascination with these exquisitely fragrant blossoms. In our area, sweet pea starts are available from late fall to early spring at your favorite local nursery, and seeds are always accessible online and in the best garden centers. Sweet peas are simple to grow and equally beautiful in the garden as in a vase. My preferred seed suppliers are Johnny’s Selected Seeds, which carries many of the most recent and outstanding introductions, and Renee’s Garden Seeds, which is a great place to get heirlooms like the delightfully scented “Cupani’s Original.”

Favorite cultivars

Here are my current favorite gorgeous items in order of choice, depending on how well they performed in the garden and vases last year: The varieties “Old Times,” “Zinfandel,” “Elegance Pink Diana,” “Pulsar,” and “Blue Celeste” are all tall, high-yielding, robust growers that deliver armloads of ruffled, long-stemmed, vibrant blooms over an extended period. When in full bloom, these kinds are sure to halt you in your tracks, and when cut and brought within, they provide stunning, incredibly fragrant bouquets. The antiques “Cupani’s Original,” “Miss Wilmott,” and “America” deserve honorable attention. Additionally, Renee’s Garden’s “Color Palette Cupid” combination is ideal for window boxes and hanging baskets.

When to plant

When planted early enough to ensure that the majority of their prebloom growth takes place during the cool weather of fall, winter, and early spring, sweet peas flower more abundantly and with better-quality blooms. If you are directly sowing your sweet peas in the garden in Northern California, the best period to ensure the most exceptional, blossom-filled crops is from late September through October. This season lasts through the middle of March if you are purchasing young sweet pea plants from your neighborhood nursery. Note: Sweet peas are frost-tolerant and do not require shelter from the cold during the winter.

Growing conditions

Sweet peas grow best in full sun, but they can handle some afternoon shadow and, as the season goes on, actually perform better under cover in the hotter NorCal regions. Sweet peas require vertical support in the shape of a trellis, arbor, fence, or obelisk to accommodate their tendril-based climbing behavior, with the exception of miniature cultivars that work best in hanging baskets or window boxes. Plant in well-tended, well-drained soil that has been amended with compost and E. B. Stone Organics for the greatest results. Certain Start The early watering requirements of your sweet peas should be met by fall and winter rainfall, but be prepared to irrigate frequently as soon as it becomes required. Feed your sweet peas regularly with a well-balanced fertilizer to sustain their aggressive growth habit and promote plentiful bloom production. When plants are producing for a while, it’s normal for them to start growing shorter stems than they did in the past. If this happens, side-dress your plants with a little blood meal and thoroughly water them. This makes it more likely that long-stemmed bloom production will resume.

Pests and problems

Be prepared with your preferred slug and snail cure because developing seedlings might suffer damage from slugs and snails. Additionally, birds enjoy nibbling on the sensitive, young foliage, so if required, put bird netting in place. These risks become less of a concern as the plants get larger, although aphids and thrips can still be a problem. Keep an eye on your plants, steer clear of chemicals, and spray any offenders with water to remove them. Pests won’t like the leaves if you feed them with a weak manure tea or diluted fish emulsion solution, which will also promote plant growth. In order to prevent mildew issues and provide proper air circulation, place your plants 6 to 8 inches apart.

Bloom period

The display starts earlier if you plant your sweet peas early! First long-stemmed, fragrant, fluttery blooms should show as early as March if planted in September or October. The bloom period will begin later if you plant later, but regardless of when you plant, your plants will continue to bloom and provide bouquet after bouquet until July in our area the more sweet peas you collect. Simply keep on cutting and filling your vases, and if you choose to leave blossoms on your vines to adorn your outdoor space, be sure to remove any seedpods that may result.

How are peas grown in San Diego?

The English or shelling pea, the Chinese pea or snow pea, and the snap pea are the three types of peas. The maturity of the pea inside the pod distinguishes the last two edible pod varieties. When harvested optimally, the Chinese or snow pea has a huge flat pod containing immature peas that can be up to 2 inches across and 4 to 5 inches long. The oval, fleshy pod of the snap pea is smaller and narrower. When the peas in the pod are halfway to fully mature, some kinds of the pod have a particularly sweet flavor. The majority of people like to eat the pods raw because of their deliciousness.

For disease resistance, an earlier harvest, increased plant size, yield, and flavor, hybrids have been created in all three areas. Peas grow and produce without many issues in regions of the country where cool, wet springs and summers are favorable, but in our region’s mild, wet springs and hot, humid summers, they are vulnerable to many diseases and typically produce a small flush of peas before the plants become stressed by mildew and stop blooming.

We sow peas in late fall (October), and depending on the weather, they are ready for harvest in around 60 to 90 days. This helps to partly combat the combination of powdery mildew and other sensitive wilts. The likelihood that the harvest will start at the same time as spring temperatures start to rise and overcast days bring high humidity—the two variables that promote mildew infection—increases the longer one waits to plant (even early maturing cultivars). It goes without saying that one should choose kinds that have been bred to be mildew resistant, but this does not guarantee that your plants will be completely safe from the issue.

In cold, moist soil, seed germination might be problematic. In warm, moist soil, it can also be a concern. Peas prefer soil that drains properly. Plant on mounds in heavy soil for increased winter drainage. As peas are susceptible to salinity, avoid using fertilizer with a high nitrogen content. Before planting, put an all-purpose fertilizer (5-10-5) into the top 12 inches of the soil. Use of fresh horse or other fresh manure is NOT permitted. seeds 1 to 2 inches deep ( 2 inches deep if your ground is still warm, 70 degrees or over.) A few days before planting, water the rows or beds to increase the soil’s moisture level. Prior to watering again after planting, especially in areas with heavy soil, wait for germination. Peas can tolerate being close together in rows, 2 to 3 inches apart, or they can wait for strong germination before being thinned. The plants will sustain one another if you plant dwarf variety in double rows spaced 6 to 8 inches apart. A short trellis is ideal for the majority of dwarf cultivars. Large climbers require strong support, some up to 8 feet.

There is some indication that some snap type peas are day length sensitive. If planted in early spring as opposed to the fall, some kinds will grow bigger, bloom more, and have a better yield. Future field trials may help to establish which kinds should be planted in the spring and which ones could be planted in the fall.

The University of California conducted three seasons of field tests on both varieties of edible pea pods in El Cajon. Evaluations were conducted for flavor, yield, maturity dates, and mildew resistance. (See the notes below)

Snap pea: Plants range in height from 2 feet to 6 or 7 feet. All have thick walls, round or oval pods that are solid, crisp, and sweet, however some have more than others. able could be shelled, cooked, and eaten raw. Later variations lack the stringy pods of the original Sugar Snap type.

China pea or snow pea: 3 to over 6 feet tall plants. Pods range in length from 3 to 5 inches and are flat and broad. The tall variety known as Mammoth Melting and dwarf grey sugar produced the greatest producing china peas in field tests conducted by the Master Gardeners.

PLANTING: Harvesting should start in January or February if the crop is sown in October to mid-November, and it should last for about two months before mildew reduces the yield. The yield starts to decrease as soon as bottom leaves start to show signs of mildew and temperatures start to rise. The vines must be pulled now. Smooth seed variants can grow in colder soil and cooler temperatures. FROST: Mature plants can withstand temperatures as low as 20°F (-0°C), but if they are in bloom or are about to set fruit, freezing usually kills both the flower and the fruit. As soon as the temperature rises once more, the plants will continue to expand and produce additional fruit.

Maturity dates are based on planting in the spring and are listed. Only compare varieties using them. The date one is planted and the winter temperatures will determine maturity.

Snap peas, green peas, sugar peas, and china peas are varieties of the Pisum sativum plant. Green peas are the most popular pea type with shells, while other edible podded kinds with the botanical names P. sativum var. saccharatum and P. sativum var. macrocarpon are also available. There are two subgroups within the edible-pod varieties: sugar or snow peas and snap peas. China peas are semi-dwarf varieties of sugar peas that grow to a height of approximately three feet and produce pods that are three to four inches long. Typically, standard sugar peas reach a height of six feet or more and yield pods that are four to five inches long. Broad and thin pods are produced by both the China and common sugar pea varieties. Dwarf Grey Sugar, the most popular China pea variety, and Mammoth Melting Sugar, the most popular standard sugar pea variety. Snap pea plants exist in both conventional and a rising variety of dwarf kinds, but all of them feature thick-walled pods that eventually become spherical, firm, and crisp. The pods can be consumed raw, boiled, or left to develop before being shelled like regular peas.

Pea varieties are further divided into groups based on a variety of characteristics, including: pod color (light or dark green); seed surface (smooth or wrinkled); days to maturity (early, mid, or late season); plant size (indeterminate/tall, semi-determinate/semi-dwarf, or determinate/dwarf); pod shape; seed size, color, and size; and more. For freezing and home gardening, cultivars with dark green pods are preferable. Although there is recent evidence to the contrary, wrinkled-seeded peas are typically thought to be sweeter and smooth-seeded varieties are better suited to cool climates.

Garden pea varieties are always being added to as breeders create new peas with enhanced characteristics. Improved traits include stringless pods, larger peas, higher yields, dwarf growth habits, more tendrils for vine support, disease resistance, and dwarf growing habits. The majority of semi-dwarf and dwarf cultivars don’t need staking or support. However, if plants are planted on a short fence to prevent them from toppling over in the wind, harvesting might be simpler. For the tall types to stay erect and allow for easy harvesting, a sturdy support system of of posts and ropes is required.
