Watering plants...

Max, never count on "sposeta" - it's "sposeta rain". The best suggestion is to have a competent person water the plants, but if this isn't possible, here's what you do: Water the plants thoroughly and let the boxes drain so they're not messy. Buy some heavy plastic sheets like those used to protect floors while painting. Bring the plants indoors, group them together, and close all the shades & curtains. This will slow their metabolism so they need less water.

The only caveat here is that although this method works beautifully for mature plants, it's a bit risky with tiny seedlings because they don't use as much water, so if the soil's too wet, their roots could rot, especially in dim lighting with little or no air circulation. You have to get the soil just right. Not soaked, but not too dry.

Take a large soda bottle and cut the bottom out. Poke it in the soil upside down. Fill with water and hope for the best. BetsyB
