Plant Chile de Arbol seeds indoors in temperate climates at least eight
weeks before the outdoor planting date. About 1-2 weeks after your
areas frost free date. (mid to late May in Northern Illinois where we are)
The de Arbol seeds should be sown 1/4 in deep and kept moist but not wet.
The seeds should also be kept in a warm place to promote
germination.
If your home is cool or drafty, a seed mate available at nurseries or a
heating pad on low can be placed underneath the containers with the Chile
de Arbol seeds to make sure they remain warm. Remember, these are tropical plants that require warm, moist conditions to sprout. Germination should
occur is 10-20 days, possible longer if conditions are less than ideal. Do
not allow the soil to dry completely out during this time because doing so
will cause seeds in the process of germination to die.
If you started more than one seed in the pots thin them to one plant
each leaving the strongest looking plant. 4-6 inch plants are ideal for
transplanting outside to your garden. Chile de Arbol plants should be set
in full sun in well draining soil 18-24 inches apart in rows that are
24-36 inches apart. This is ideal placing so if you have limited space in
your garden as I do; they can be placed a bit closer and still do well.
Once well established and the weather is warm the Chile de Arbol plants
should be mulch with untreated grass clips or another organic material and
watered well during dry weather. The Chile de Arbol peppers should start
to ripen about 75 days after transplant. There is no
reason to wait that long, these spicy peppers can be picked and eaten
while still green and immature. I always do!
