  • AquaSpikes are a great, handy, watering device. Only a little bit of effort is needed in the beginning to make sure that you set them up properly. Once they are set up, they can last for years with very little work. Your plants will fluorish with this seemingly endless supply of water.

    Small Containers Use a single AquaSpike in containers up to 5" in diameter.
    Large Containers For containers larger than that, use 2 AquaSpikes, placed opposite each other, near the roots.

    For extended watering periods, double the number of AquaSpikes used. Using AquaRocks will yield the best results, and will be the easiest to set up. By using AquaRocks, you will turn the AquaSpikes into a slow-watering system.

    Standard Instructions

    1. Empty and rinse a 2 liter bottle.
    2. Remove the cap and safety ring.
    Removing the safety ring is important: There are no threads on the AquaSpike. The bottle and the AquaSpike will make a very nice tight compression fitting, once the safety ring is removed.
    3. Fill the bottle with water. If you are not adding Aquarocks, skip to step 6.
    4. Add 1/2 teaspoon of AquaRocks to the bottle.
    5. Wait 5 minutes. The AquaRocks will turn into gel and will rise up about 3-5 inches into the bottle.
    6. Attach the AquaSpike to the bottle.
    7. Bring the AquaSpike and bottle to the location where it is to be inserted.
    8. Quickly turn the bottle over, and slide the AquaSpikes into the ground, up to the collar of the AquaSpike.
    It is normal to have a small amount of water may spill from the AquaSpike as you turn it over. The AquaRocks will start to float down to the bottom, and into the AquaSpike. As they do, the water will flow out of the AquaSpike, into the soil. As the AquaRocks settle, the flow rate will slow down. The AquaRocks should now be filled into the AquaSpike, and rise up about 2 inches into the bottle.
    9. A configuration of AquaRocks with a 2 liter bottle will last about 10-14 days.

    The bottle will start to collapse on itself over the next few days. That is normal.


    For Maximum Results:
    * Thoroughly water the soil BEFORE putting the AquaSpike into the soil.
    * Add AquaRocks to the soil, also. Just make holes in the soil, using a pencil or screwdriver, and sprinkle a few pinches of AquaRocks into the hole. Repeat this in 4-6 spots around each plant.


    Alternate Instructions For Permanent Installations

    If you want to keep the AquaSpikes in place, then a few additional steps will make refilling the bottles very simple.

    1. Cut the bottom of the bottle off.
    2. Follow the Standard Instructions above.
    3. Place the bottom of the bottle into the main portion of the bottle to reduce evaporation.
    4. When it is time to add water just remove the bottom cut-off and fill with water.

  • What are AquaSpikes?

    How often should I water my plants when using AquaSpikes?

    That will depend on how you are using the AquaSpikes in your plant care program. If you are just using the AquaSpikes alone for deep root watering, it may only take a 1 hour or so to fully deep root water the plant. If you add AquaRocks®, sand or even stuff a few wet paper towels into the AquaSpikes, it will take 1-5 days for the water to slowly seep into your plant.

You will really see the difference in all your flower gardening, vegetable gardening, indoor gardening and container gardening.

    Why does the bottle collapse?

    The suction created by the water being pulled out of the bottle can cause the bottle to collapse. That's okay; it tells you that the soil is actually drawing watering out of the bottle as it needs it.

    The water does not seem to be draining out of the AquaSpikes, what should I do?

    It may be that you have added too many AquaRocks to the bottle. You should try and remove some of the AquaRocks. When you turn the bottle upside down again, it should provide a slow, steady drip if you have the right ratio of AquaRocks to water. If you lift up the AquaSpike and bottle and there is a little drip on the tip, your plants will be just fine and getting the water they need.
