Instructions for use

Expandable accordion for detailed instructions on the application of GeoPlant Aquasafe: for specific purposes. More detailed than the short instructions attached to the packages.

Dosage of GeoPlant Aquasafe (GPA)

  • Generally: 10-20 ml per 1 liter of soil/plant substrate. 15 ml of GPA weighs approximately 10 g. This is a good compromise for soils/plant substrates or garden soil of "medium quality," meaning it falls between very sandy soil and high-priced super flower soil or fine compost.

  • For anything beyond small pots for indoor plants, refer to the section "Practical tools, measurements, and weights."

  • When planting a balcony box, for example, it would become unnecessarily cumbersome to scoop approximately 20 times using the measuring spoon provided with each GPA package up to 12 kg or an alternatively repurposed tablespoon.

  • In this case, a standard measuring cup with milliliter or cubic centimeter markings in increments of 100 - and a bit of "eyeballing" - would be much more practical.

Mixing with soil/plant substrate

  • GPA can be easily and fairly evenly mixed with soil. Neither the fine granules nor the pellets need to be pre-soaked in water.

Practical tools, measurements, and weights

  • The measuring spoons provided with each container of GeoPlant Aquasafe (GPA) up to 12 kg can hold approximately 10 ml up to their lower mark and up to 20 ml when filled to the top (levelled).

  • The specific weight of GPA is 0.67 g per ml. Therefore, the average weight between 10 and 20 ml is approximately 10 g. This applies equally to GPA pellets due to their lower bulk density compared to the fine granules, eliminating the need for separate dosage recommendations for the pellet variant.

  • A leveled tablespoon holds approximately 8 g, and a heaped tablespoon holds around 12 g. Yes, it's easy to lose such a provided measuring spoon before finishing a GPA container suitable for the intended application.

  • In practical terms, using an old or temporarily "misused" leveled or full tablespoon for measuring yields measurements that are "not significantly" different.

  • Instead, dosage aids for laundry detergent (with markings of, for example, 20-80 ml) or caps from liquid laundry detergent can also be used. The capacity of the latter (e.g., 60 ml) is usually indicated on the plastic bottle.

  • For mixing GPA with smaller amounts of soil, plant saucers with a certain diameter or (disused) wash basins are suitable.

  • Cost-effective or discarded kitchen measuring cups (with ml or cc markings up to, for example, 1 liter) can be used to extract soil/planting substrate (e.g., coconut coir or CFP) from larger containers by the liter.
  • A standard garden wheelbarrow holds at least 80 liters of soil. It has a specific weight of around 0.7 kg per liter (depending on moisture content and type of soil). Half to a whole garden wheelbarrow would be a suitable method for storing excavated soil for planting larger shrubs and trees, while also mixing in GPA.

  • By the way, for (hobby) gardeners who prefer not to use a ruler or measuring tape in the garden, a thumb's width is approximately 2-3 cm, and the length of an outstretched hand is approximately 15-20 cm.

Indoor plants and outdoor potted plants, planting or repotting

  • Mix in ½ to 1 measuring spoon (10-20 ml ≈ ½ to 1 heaped tablespoon) of GeoPlant Aquasafe (GPA) per liter of potting soil, thoroughly blending it, for example, in a larger plant saucer or a disused wash basin.

  • This creates an ideal planting substrate that retains water and nutrients. We recommend covering the top of the soil-GPA mixture with an additional 2-3 cm of potting soil without GeoPlant. This helps conserve GeoPlant for future root balls. The roots draw water from below, and the water stored in the numerous mini-depots of GPA around the root ball evaporates relatively unused due to sunlight, wind, or heating.

  • Alternatively, fill the pot with approximately 1/3 of potting soil. Add and distribute ½ to 1 measuring spoon of GeoPlant per liter of soil. Place the plant and leave space at the top for a layer of soil without GPA, approximately the width of a thumb (as mentioned above).

  • Important: After planting in the pot, water it gently until some water begins to drain from the bottom of the pot.

Balcony boxes

  • In an balcony box measuring 80-100 cm in length (depending on the height and depth), approximately 18-22 liters of soil can fit, excluding the volume occupied by the root balls to be placed there. Some space should also be left at the top for watering.

  • Therefore, from a 20-liter bag of soil, only about two-thirds would fit into such a balcony box. It wouldn't necessarily make sense to scoop the soil from the bag into the box using a (kitchen) measuring cup, unless you have limited physical capacity.

  • Instead, you can follow these steps:

    • 1. Position the plants with their root balls in the box as intended.

    • 2. Fill the box with soil or planting substrate from the bag until the top of the root balls is approximately level with the soil surface.

    • 3. Remove the plants from the box, estimate the volume of soil filled with a certain level of approximation (around 13 liters in the example).

    • 4. Sprinkle the appropriate amount of GPA over the soil in the balcony box (e.g., 13 x 10-20 ml, approximately 130-260 ml, or an average of about 200 ml), and then mix it with a small shovel, planting fork, or by hand. It is easy to mix because GPA does not require prior swelling in water (like some competing products) before being mixed with soil or planting substrate.

    • 5. Replant the plants and cover the root balls with soil without GPA to a thickness of about the width of a finger. This is important because: a) the roots draw water from the numerous mini-depots created by GPA from below or around the root ball, not from the top; b) if the root balls are not covered adequately, they will dry out unnecessarily due to sunlight and wind, and some of the water stored by GPA will evaporate from the top, serving no purpose for the plants; c) UV light accelerates the biodegradation of the superabsorbent material in the GPA composite and affects its long-term effectiveness; d) the goal is not to let the GPA mini-water reservoirs around the plants dry out due to sun and wind, but rather to allow the roots to draw the stored water from the root zone.

  • Furthermore, the root balls should not be covered too deeply. This would lead to a lack of oxygen for healthy plant growth. Many specialized websites of nurseries, online plant shops, etc., provide visual explanations. You can search the internet with terms like "planting too high or too deep" for more information.


"Boosting" existing plantings

  • For existing plants that have required frequent watering and have been a cause for concern during short vacations, GeoPlant can be used as a suspension for "boosting" their performance. To do this, you can mix 2 measuring spoons of fine granules (40 ml or approximately 27 g) with 1 liter of water and pour it into holes made around the plant roots using a simple planting stick or gently drilling from above into the root area.

  • It's important to note that if you encounter resistance due to larger roots, you can simply try another nearby spot.

  • An example of such application can be found on this website: "Less Watering in Rome" (assuming it is a case study or reference illustrating the effectiveness of GeoPlant in reducing the need for frequent watering).

  • GeoPlant can provide a reliable and long-lasting effect for 2-3 years, but it's important to understand that biodegradable materials cannot maintain their full effectiveness for up to 5 years. Therefore, periodic "boosting" with GeoPlant suspension can help ensure consistent results over time.

Flower/Perennial and vegetable beds

  • To distribute GeoPlant evenly on the soil surface, you can use approximately 300-500 ml or 150-250 g (equivalent to 15-25 measuring spoons) per square meter of ground area. After spreading it, you can use a suitable tool such as a rake, cultivator, harrow, or fork to work it into the soil to a depth of about 15-20 cm (approximately the length of a hand). Finally, water the area to ensure proper activation and integration of GeoPlant with the soil.

Larger perennials, shrubs, and trees

  • To mix the excavated soil or the planting soil that will be used around the root ball, you can incorporate 1-2 measuring spoons of GeoPlant Aquasafe (GPA) per liter. Ensure that the soil-GPA mixture is introduced particularly at the bottom and around the root ball. As the roots continue to grow, GPA will be further distributed within the root zone, allowing the drying roots to draw water from the GPA depots through osmotic pressure. Over time, in the root area of larger plants, the same standard ratio of GPA to soil/planting substrate (1/2 - 1 measuring spoon or 10-20 ml/7-14 g of GPA per liter of soil) will be achieved, even with an initial double dosage.

Lawn seeding and laying sod

  • The incorporation of GeoPlant is done to a depth of approximately 5 cm. The required amount per square meter is 3 grams (≈6 ml) of GeoPlant per liter, which is equivalent to 150 grams per square meter. If deeper incorporation is desired (as grass roots can grow up to 25 cm deep), the amount per liter can be reduced to 2 grams. The cost burden for this application is a maximum of €1.00 per square meter of lawn, and this cost is spread over a period of approximately 3-5 years, during which humus formation also increases. The annual cost of GeoPlant is approximately €0.20 per square meter of lawn.

  • In comparison, there will be higher costs for water and possibly wastewater, but there will be a 50% reduction in watering time, less need for fertilizer, and overall improved growth.

  • Therefore, the use of GeoPlant for safe lawn establishment proves to be economically beneficial in multiple ways.

General: Dosage, moisture control, and minimal fertilization

  • GPA is equally effective and economical to use. Only for extremely dry/sandy soils, we recommend a maximum double dosage (1-2 scoops/20-40 ml/13-27 g per liter of soil).

  • You can also use commercially available moisture meters/water gauges, which are not expensive. None of us can see or feel the root zone of our plants. Room/outdoor climate, sun or shade exposure, soil or planting medium quality can result in various conditions.

  • GeoPlant also stores nutrients. Therefore, fertilize sparingly, not exceeding the minimum recommended for each plant and crop. Less is often more and helps protect the environment.
