Slow watering for thirsty plants. During the hottest weeks of summer tomatoes need to have a regular supply of water. If your garden is small or you don't want to bother with soaker houses you can use jug drip systems in between watering. Take several old gallon jugs put tiny pinholes in the bottom and fill with water. Keep the cap on and place in-between tomato plants. The water will slowly leak out providing a steady watering in-between rainfalls or weekly watering routines. ~~~~~~~~~~~~~~~~~~~~~~ Catch the drips from your air conditioner. If you run an air conditioner you can use the condensation run off to water your garden or container plants. Just place a five gallon pail under the air conditioner to catch the condensation drips. The water that collects is pure.
