Ginger harvest and tasting
9 to 10 months after planting, when the green parts dry out, part of the rhizomes can be dug up and used for consumption. To obtain younger and more lemony ginger, it can be harvested after only 5 or 6 months. If you want to fragment your rhizomes for planting, you must ensure that at least one bud is present on the fragment in question.
Ginger keeps quite a long time, but its flavor diminishes over time to gain in spice. It is therefore best to eat the rhizomes fresh. Renowned for its revitalizing power, it is also very good for relieving stomach aches and nausea in pregnant women (rub the root on a little bread in the morning). It is antiseptic, antibacterial, relieves headaches, rheumatism. He is a real star of Asian medicine and gastronomy!
How to maintain them?
Asters like fertilizer. Bring it to them at least once in the spring, scratching the clumps superficially so that they retain their vigor. You will use organic fertilizer. If you apply flower plant food, you will get much more vibrant flowers.
To avoid powdery mildew attacks, spray the foliage and especially make sure that the soil is always slightly damp. It is also recommended to divide the clumps every 2-3 years.
Tall species can be staked, as they are indeed sensitive to autumn rains. You can also push the branches into the ground and pinch its stems 15 cm from the ground, usually at the end of May. This helps to make the tuft more compact.
Prune the aster
You just have to cut back the stems once the flowers have faded at ground level. Before winter, it is recommended to remove all diseased leaves.
How to water the asters?
While asters in pots require regular watering to keep the substrate moist, asters in the ground are watered when the period is dry and hot and after planting.
