Serrano Chile Pepper Seeds Reviews

Excellent seeds that never disappoint.

My friend asked me to grow Serrano Chile peppers. For me, peppers are difficult to grow. I bought the seeds and your recycled paper pots (these are great - start the seeds indoors and transplant the whole container in the soil!) The peppers came up. They had the second set of leaves. My dog decided to eat them. She left the stems. I replanted the Serrano Chile seeds again. They came up again, so I am happy and my dog won't eat them anymore. My friend will be happy too. Your products have never failed. I won't use anything else. If I could, I would rate you 10 stars!

Only one seed came up and to date there are no flowers or peppers on this single plant.

Owner Response: Hi Janice, Out best tips for germinating peppers are that they should be starting indoors and often a heat mat is necessary since they need higher tempertures to germinate than any other crop we carry. Our seeds are tested frequently by a third-party laboratory to ensure germination rates exceed federal and out own standards. A customer service agent will be with you shortly to help.

These are amazing. I love them so much. They were easy to start and resilient when transplanted. They were my first pepper variety to start producing, andhave been full of fruit all summer long.

We planted and watered these according to the directions, but they only grew a few spindly plants a couple of inches tall that never developed.

Owner Response: Hi E, Thank you for sharing your feedback. From your other reviews, it reads as though you sowed these seeds outside. We recommend sowing peppers indoors (see packet instructions) in order to achieve the proper soil temperature for germination and to give pepper plants a head start since they take a very long time to mature. You can find more tips for success on the seed packet and in the Sow and Grow article linked in the Learn More tab on this product page.
