The Guajillo Pepper pronounced "gwa-hee-ho" is a pepper native to Mexico, very popular because it is used in Salsa sauces, and is the main ingredient in chili paste. In Tunisia it is also the pepper used to make Harissa. With its fairly thin skin it is very easy to dry. Once dried, its color will change from red to a very dark red, even tending towards brown or black. It has a rather horn-like appearance with a smooth texture to the touch. Placed between 0 and 3000 on the Scoville scale, it is a fairly mild pepper. The plant can reach 60 cm in height and its fruit is harvested once red.

What Equipment for growing my peppers?
To optimize your results we recommend you equip yourself with:
Guajillo Pepper Seeds.
An enclosed growing space such as a mini greenhouse.
Coco coir pellets, peat, or cotton (to germinate the seeds).
Labels (to avoid mixing up your seedlings).
Potting soil (ideally a mixture of 50% black peat and 50% blonde peat) or flowering potting soil which will also work.
Pepper fertilizer or tomato fertilizer, or 5 5 10 fertilizer for those in the know.
A water sprayer or watering can.
Gloves (if you don't like contact with soil).
Pots with a diameter of 7 or 8 cm at first before using 10-liter pots or larger depending on the pepper for repotting
To make your life easier, we offer our mini greenhouse for growing your peppers.
How to Germinate my Pepper Seeds?
Growing peppers is a process that requires patience and some knowledge, but don't panic, we'll explain everything you need to know to germinate your pepper seeds!
Pepper seedlings are sown at the beginning of the year, generally between January at the earliest and March for the beginning of spring. To do this, you will need the equipment listed above.
You then have 2 options:
Plant your seed directly in a pot full of potting soil at half a cm depth
Place a seed on a coco coir pellet or on a piece of cotton.
In both cases, once the seed is in place, you will need to spray enough water to moisten the soil or cotton without soaking it, then place your coco coir pellet or cotton in a container like a mini greenhouse which will retain the heat and humidity, thus providing oxygen. If you use a flower pot, you can simply stretch film over it and make small holes with a toothpick to oxygenate the plant.
The ideal is to maintain a constant temperature of 28 degrees. You can store your container behind a sunny window, on or near a radiator, or on a heating mat or heating pad designed for this purpose.
OUR TIP:
Place your mini greenhouse on your internet box!
Remember to air out your growing area from time to time to prevent the appearance of fungi while keeping the soil moist. Once the first leaves appear, you will need to make sure to give your seedlings enough sun for 12 to 14 hours per day. Once the second set of leaves is well developed, you can then repot them.
Once potted, keep your plant near a heat source and exposed to the sun (ideally try to filter the light to avoid heat stress)
After the Ice Saints around mid-May, you can move your plant outdoors and plant your pepper in the ground if you wish, or leave it in a pot and place it on a balcony, a window sill, or even along a wall, preferably on the south side.

How to water my Guajillo Pepper?
When watering your Guajillo pepper, be careful not to overwater. Too much water can drown the plant and lead to its demise. You simply need to let the soil dry between each watering to avoid insect proliferation and drowning of the plant.
Once the plant is well developed (once your plant reaches about thirty centimeters), you can cause water stress by stopping watering the plant for several days before resuming watering (however, be careful not to abuse this technique, it would be a shame to let your pepper plant die).
How to properly prepare my harvest?
Once your pepper plant is in place, here are our tips to optimize your future harvest:
When your pepper plant reaches a height of 15 to 20 cm, you can pinch the top of the stem (without breaking it) which should allow the plant to grow bushier and produce a little more.
If flowering is early for one of your plants, remove the first flowers to prevent them from demanding too much energy from the plant.
If your pepper plant is outdoors, insects will take care of pollinating the plant which will then produce peppers. If your plant is indoors, you will need to do this manually. Take your clean finger and rub it lightly against each flower from one to another.
Don't hesitate to use a bamboo stake or rod to support your plant.

Customer reviews
J'ai semis 68 godets (jalapeño, pasilla, ancho, corno di toro) et les guajillos de sauce picante. Tous on germé sauf les guajillos. Même environnement, arrosage, terre, lumière, température etc. Je suis assez expert, je sème mes propres légumes depuis plus de 25ans. Les graines n’étaient pas bon c'est claire. Très déçu car je n'ai pas commandé ailleurs et donc cette année pas de guajillos qui sont à la base de la cuisine mexicain. Frais de livraison très élevé pour un enveloppe simple.
