When growing shishito peppers, you will want to wait until the threat of frost has completely passed. This heat-loving veggie will do best in weather that is between 70-90 degrees Fahrenheit.
If you live in a warm climate, you can start your peppers outside in the spring. If you live in a cooler climate, you should start growing your peppers inside about 8-10 weeks before the last frost date, and then move them outside.
Shishito peppers plants will be ready for harvest within about 60-65 days after planting. Remember, shishito peppers are best when picked and cooked before they start turning red.
You will want to plant shishito peppers in your garden when daytime temperatures are at least 70°F, and night temperatures are above 55°F; soil temperatures should be between 70-80°F.
When planting your peppers you will want to maintain spacing of 12–18 inches apart, and, if you are growing in a raised bed, allow 24–36 inches between rows. If you are growing in a container, you do not need to worry about rows.
If you are growing shishito peppers from seed, you should start the seeds indoors 6-8 weeks before moving them to your garden. The shishito pepper seeds will typically have a germination rate of about 8-10 days, and then they can even take about 3-4 weeks to sprout.
It is helpful to learn how to grow shishito peppers from seed, but if you’re growing from transplants, it makes the job significantly easier. Seeds are temperamental, where seedlings are simply eager to grow.
When growing your seedlings, you should wait until at least 4 weeks after the last frost date to transplant them outdoors. Be sure that your seedlings are at least 8-12 weeks old, if you are not using a Gardenuity Garden Kit to grow your garden!
When transplanting, be careful not to expose the roots of your plants to the sun. Additionally, keep the soil and root ball extra moist so that the root system does not become damaged in the transition.
Shishito peppers are versatile, and they are a great addition to your summer container garden. Growing shishtio peppers in containers or pots is as easy, if not easier than growing in a raised bed. The three things you will need to provide your garden with are full sun, a well-drained soil, and a pot that has great drainage.
When growing shishito peppers in a pot, choose a container that is at least 12 inches across. You must make sure that there are plenty of drainage holes for your pepper plants. You can find a potter or a bucket at the store, or, if you are growing a Gardenuity Garden Kit, you will have your Grow Bag ready for your peppers.

Watch them grow!
The most common issues that gardeners face when growing their shishito peppers include underwatering, overwatering, over-fertilization, transplant shock, fungus, and not enough sunshine. Plants will drop leaves, become wilted and develop spots as a result of over or under-watering. You can avoid these problems by paying close attention to how your plant is growing, and not watering it until the soil has dried almost completely.
Once your transplants are in the ground, it will not be long until your peppers are ready for harvest! Shishito peppers are fairly easy to grow and care for – all you need to do is pay close attention, provide them with enough sunshine and water, and don’t overdo it. Simple enough.
Pepper production is best in fertile, well-drained soils with a pH of 6–6.8. While pepper plants do not prefer too much organic fertilizer, a homemade compost at the base of the plant will provide great nutrients during the growing process.
Shishito peppers should not be planted outside until the temperatures are at least 70°F during the day, and when night temperatures are above 55°F. The ideal soil temperatures should be between 70-80°F for the best pepper production.
Your shishito peppers will require full sun, which means at least 8 hours of sunlight each day. If you are growing your peppers indoors, be sure to place them in a south-facing window; grow lights will be great tools for growing shishito peppers inside, too.
Shishito peppers will do well with about ¼-¾ gallons of water each week. Be careful not to overwater your peppers, as they do not like to live in wet soil. Typically, you can aim to water your plants once every 4-5 days. In exceptionally hot and dry summers, you can water every other day, as long as the soil is drying out in between waterings.
Shishito pepper plants can be prone to many insects such as broad mites, aphids, greenhouse whiteflies, two-spotted spider mites, and western flower thrips.
The best way to control pests, especially aphids, is to include companion plants that deter pests from settling into your garden. If the pest numbers become too large, you can wash them off of the plants with a strong jet of water.
The following plants are great companions for your growing shishito pepper garden:
Keep in mind that you should not plant fennel or apricots with your pepper garden!
After your young plants are in the ground, the growing timeline for shishito plants is quite brief. Prepare to receive your first harvest within 60-65 days of planting your shishitos – very exciting.
Transplant shock can happen when planting your seedlings in the ground for the first time. Be sure to keep a close eye on your seedlings for the first week after planting, and allow them to get acquainted with their new environment. Remember, be sure to give them plenty of water and sunshine.
Shishito plants are compact, but they do grow to be about 15 inches tall, and 18-20 inches across. As your peppers grow, keep an eye on the coloring of the fruit.
You will know that it is time to harvest your peppers once they are 3-5 inches in length, and when they are a bright green color. Some recommend that you wait for the peppers to turn a deep, dark green color before picking.
If you wait too long to harvest your shishito peppers, they will start turning red. Red shishito peppers are still edible, however, they don’t have as rich of a sweet and spicy flavor.
Take a look at the following steps for instructions on how to harvest your fresh shishito peppers:
Shishito peppers are most commonly harvested when they are 3-5 inches in length, a deep green color, and when they have been growing for about 60-65 days. Be careful not to harvest your peppers before they are at least 3 inches in length.
Shishito peppers will last up to about 2 weeks once harvested. To keep them fresh for longer, store them in a paper bag in the warmest section of your refrigerator. Some chefs even enjoy drying out their shishito peppers, so that they can be used all year long.
The best way to enjoy shishito peppers is by making beautiful dishes out of them. Sometimes all you need is a little bit of olive oil and sea salt, but if you are looking to make something more creative, shishito peppers will be your best feature yet.
