22 Unusual Tips for Flower Cultivation -神奇 Use of Sawdust as Substrate Turns Waste into Treasure with Sufficient Fertilizer
The web introduces some common knowledge about flower cultivation. In the 22nd unusual tip - the magical use of sawdust as a substrate to turn waste into treasure with sufficient fertilizer, the editor will introduce it next.
Usually, after home renovations, sawdust is often discarded as garbage. However, sawdust is very useful for us, the flower cultivation enthusiasts, and we can turn it into treasure.
1. Cuttings: Using sawdust as the cutting substrate for plants like roses, gardenias, and pomegranates shows significant results, much better than soil or water cuttings. It roots quickly, has more roots, and the plants are robust. A great advantage is that after the plants have rooted and survived, they can be transplanted into the pot soil together with the clumpy sawdust, which does not damage the roots, making it easy to grow and bloom early. Even for difficult-to-root species like azaleas, I have succeeded in rooting them, and even the tender tips of begonias can root quickly. The reason is that sawdust has better water retention and breathability than soil, ensuring sufficient oxygen.
Specific method: Fill the sawdust in a flower pot, pour boiling water over it several times for complete disinfection, then after the temperature has dropped, squeeze out the excess water (making the wet sawdust not drip water when pinched), and you can start the cuttings, the same as with soil. Keep the sawdust moist after planting, and it will root and survive quickly. This method can be implemented all year round, but in winter, it needs to be placed on a sunny windowsill inside the house with heating.
2. As a high-pressure wrapping substrate: Sawdust, due to its loose texture and controllable moisture, is also superior to other substrates, with faster root growth, safer, and higher survival rates.
Specific method: After stripping the plant, fill the plastic bag with a mixture of wet sawdust and half yellow soil, then tie both ends tightly.
3. As fertilizer: Using wet sawdust to make fertilizer is comprehensive in nutrition, economical, simple, and hygienic.
Specific method: Mix wet sawdust with an appropriate amount of calcium superphosphate or potassium phosphate or urea, and add organic fertilizer if possible, put it in a plastic bag, and tie the bag mouth. Turn it over every two weeks to accelerate even decomposition. In spring and autumn, it can be used after about six weeks.
Notes: When using, mix in 50% soil.
The above lists a few points; the rest is omitted. In fact, sawdust has even more uses than these. Everyone can use their imagination and try it out.
(Oops, I forgot an important point, let me add it here - sawdust should be fermented before use.)
When I use sawdust to make fertilizer, I add an appropriate amount of rapeseed cake (or soybean cake) obtained from fish farmers, as well as some chicken and duck manure (last year I used cow dung), then added a little water and let it ferment. After rotting, let it dry to half before using. This method of making sawdust fertilizer has a more comprehensive nutrient profile. It is better to make it in spring and summer because the temperature is higher and fermentation is faster.
