Water Bottle Drip System

I cut back on watering my garden due to California's drought, and my plants have been suffering for it.  In an attempt to be even more water-wise, I recently installed a make-shift water drip system.  

I made a single 1/16-inch hole on the bottom of an empty Organics plastic soda bottle and buried it right-side up in the ground next to a plant.  After filling the bottle with water, I replaced the cap and close it tightly.  Using a funnel makes refilling these bottles a quick and easy task. 

I can go days without refilling these bottles.  And by delivering water directly to the roots, I am minimizing water that is  lost by evaporation. 

Reduce Your Water Bill By Using This Watering Schedule

According to this website, most landscapes are over-watered by as much as 50%.  You may be able to reduce your water bill by following this watering schedule: http://www.contracosta.watersavingplants.com/WateringTips/HTML/index.html.

Please Note: This irrigation guide is tailored to clay and loam soil, and weather conditions in Contra Costa County, California.

Reduce Your Water Bill by Using These Drought Tolerant Plants

The Contra Costa Water District has compiled a list (and photos) of drought tolerant plants that are tailored to Contra Costa County conditions.  They also identify drought tolerant plants with additional characteristics.  For example, some drought tolerant plants attract hummingbirds or butterflies.  Some plants are good for screening, and other plants are deer-resistant, etc.

Container Plants Survived Week Long Vacation with Easy DIY Tricks

I went on a week long vacation to the tropics.  I started some seeds in containers on March 28, 2011 and left them outdoors in DIY mini-greenhouses to germinate.  Most of them had already sprouted before leaving for my trip.  I watered the plants thoroughly, and used the plastic bag method and homemade greenhouses to keep the soil moist and the plants happy while I was away.  I am happy to report that not only did all of the seedlings survive, but also more seeds have sprouted!

Smart Hanging Basket Liners

If you are tired of constantly watering your hanging basket plants, consider updating your liners with AquaSav's baket liners.  These liners require 50% less watering than standard basket liners.  A layer of 100% recycled post-consumer plastic liner is sandwiched between natural coir fiber.  The replacement liners are inexpensive, and come in various sizes.  Alternatively, you can line the bottom of an ordinary basket liner with pond plastic or even an inexpensive plastic bowl.

Self-Watering Conversion Kits for Planters

Before taking your next vacation, consider upgrading your containers with self-watering conversion kits.    These kits convert ordinary pots into self-watering planters.  These kits will reduce your time spent on watering your plants.  All you have to do is pour water into the fill tube.  The water in the reservoir will evaporate and moisten the soil.  Pour more water into the fill tube when the water level indicator indicates the reservoir is low.  You can also fertilize your plants by pouring in liquid or water-soluble fertilizer.

These kits come in two sizes:
Self-Watering Conversion Kit, 1 Quart ($14.95): Holds 1 quart and fits pots up to 10" to 14" in diameter at the rim.
Self-Watering Conversion Kit, 1 Gallon($17.95): Holds 4 quarts and fits pots between 16" and 20" in diameter at the rim.

DIY Container Watering System: No Need to Water Plants for Weeks!

Last month, I went on a 3 week vacation. I have never left my plants alone for that long so I was a little worried they would die while I was gone. I transferred a bulk of my seedlings to a friend's backyard, and saved a few to test out a homemade greenhouse & drip system combo I had in mind. My experiment worked out beautifully! I returned to find all of my plants visibly taller, fuller and happy.

Ironically, a majority of the seedlings I had transferred to my friend's backyard died. The area I planted the seedlings in flooded, and the poor things were submerged under 3-inches of rainfall. Fortunately, the roma tomato, red bell pepper, bush bean and habanero I planted in her organic garden survived.

This system worked so well, I plan on using this system year-round. It is very simple to make, virtually free to create, and best of all I can literally go weeks without watering my garden!

DIY Container Watering System

• Materials:
• Large Plastic Ziploc Bag or Other Plastic Bag
• Empty Water Bottle with Cap
• Thumbtack (or some object that can puncture a water bottle)
• Pen
• Duct Tape or Rubber Bands*
• Bamboo Stakes*

• Directions:
1. Allow yourself at least one to two days prior to departure to setup and adjust your watering system.
2. Water your plant(s) thoroughly.
3. Take the thumbtack and stick it through the bottom of the empty water bottle to create a small hole. You can alternatively puncture the flimsier side wall, but make the hole near the bottom of the bottle. See Fig 2.

4. Fill up the water bottle with water. At this point, you will see the water freely spilling out of the hole. See Fig 5. Replace the water bottle cap, and tighten the cap until the water is just slowly dripping out of the hole. See Fig 6.
5. Place the water bottle right next to your plant. Mark the water level with a pen. See Fig 3.

6. Create a tent over plant with the plastic bag. Make sure the plant leaves are not touching the plastic bag. If you are leaving your plants alone for a long time, make sure there is enough room at top to accommodate new plant growth. See Fig 4.

7. Check and Adjust your System. Check on the plants the next day to see how much water was released. You will probably find that some bottles released water at faster rates than others. I tinkered with my system so that no more than an 1/8 of the water was absorbed a day. Adjust the release of water to your liking. You can loosen the cap to increase the water flow. Or you can tighten the cap to decrease water flow. The make-shift greenhouse (i.e., the plastic tent) will help conserve the moisture. See Photo.

(*) You can use bamboo stakes, duct tape or rubber bands to help create the tent. If you have a standard 6" terracotta pot and a small plant, then just use the large ziploc bags. The bag is stiff, sturdy, and fits snuggly over the lid of the pot.

Vacation Watering Tips for Potted Plants

One Week Vacation
Most of my plants are in unglazed terracotta pots so water evaporates quickly. I normally have to water my plants daily during our hot, dry summers. I once unexpectedly had to leave my plants alone for a week during the summer, which is pretty much a death sentence to a container garden. I didn't have time to work out a drip system so I moved all of my plants to a shady area of my patio, watered them thoroughly, and wrapped them in plastic bags. I was pleasantly surprised to find all of my plants alive and in good condition. Not only were they all alive, but one of my lilies had bloomed.

Plastic Bag Wrapping Method (Recap):

Materials:

• Plastic Bags. I used the kind that stores use to bag your purchases. Just make sure there are no holes in the bags.

Instructions:

1. Move the plants to the shadier side of your apartment patio/balcony.
   
2. Just before you leave, water the plants thoroughly (i.e., until water begins to drip from the bottom of the container).
3. Wrap each pot in plastic bags to prevent water from evaporating. Just set the pot in the bag and then tie the bag around the base of the plant. Try to tie the bag as close as possible to the trunk or stem of the plant. As water rises it will hit the plastic ceiling, and drip back down to the plant. Just make sure there are no holes in the bags you use.

Three Week Vacation
It is chilly and humid now so there will be less evaporation. Some of my plants are dormant now so they will not be needing as much water as they did during the summer. However, I do not believe my plants will be able to sustain themselves for 3 weeks on the wrapping method alone. I'm going to combine the wrapping method with a drip system for my large potted plants. Then I'm going to have a friend care for the bulk of my seedlings. I will use some of my duplicate seedlings to see if they survive the 3 weeks in a green house system I have in mind for them. I'll report my findings in January. Happy Holidays Everyone!
