We’ve only had one night of frost so far but that was enough to kill all our outdoor tía tô (perilla) plants. Luckily, we’ve already started winterizing our herbs garden. This year, we’re experimenting with hydroponically growing our herbs indoor with the hope that more godlike control over our plants’ world will keep us well supplied with fresh herbs until next spring. Growing hydroponically is a technique for growing plants without soil, with well defined nutrients solutions delivered directly to plant roots. Another advantage for us is the ability to heat up the nutrient solution coursing through the system and keep the plants warm in spite of the cold air temperature in the apartment. Lay the nutrient tubing underneath the other pots and even the non-hydroponic plants will have warm happy feet!
