Question
I am very new to gardening and I'm currently in northern Japan.  I've started some jalapenos and habaneros from seeds and they all are at the stage of the first 2 leaves (not true leaves yet).

Everywhere I have read that these types of pepper plants, because they are native to dry, desert areas, do not require much water.

My question is, does this low water requirement also apply when the seeds have just germinated?  In other words, how much should I water them as the seedling is growing?

Also, at what stage should I start to harden them off outside and eventually plant the seedling?  How many sets of leaves?

At the moment, outdoor highs are around 25 C (77 F) and lows are 15 C (60 F).

Thanks for any advice

Answer
James, while it is true that jalapeno pepper plants do not need much water, that only applies once they fully mature. As with all seedlings, keeping the soil medium moist is critical in their initial stages of growth. Be sure to check them everyday to ensure the top of the soil is moist to the touch. And also be sure that the containers in which you are growing them have drainage holes to allow excess water to escape. Otherwise, the roots can rot if left soaked for extended periods.

Hardening the seedlings off is essential to properly acclimate them to outdoor conditions. This is necessary because they have been in a controlled environment over the winter and need to be introduced slowly to the changes in temperature, wind, sun, and rain.

This process is accomplished by placing the seedlings in a shaded or covered area for a few hours the first day to protect them from the wind and sunlight. A covered porch or a coldframe are both good options. Leave them out 6 hours the second day, 12 hours the third, and the entire day the fourth. Each day move them more towards the sunlight. The reason for this is to protect them from sun scald.  You can then plant them into the garden 7 days after starting this process, assuming that all danger of frost has passed.

I hope this answered your question. Please write again if I can ever be of assistance.
