How to grow potted spring grass? Detailed care guide

Today we are talking about spring grass, an unusual succulent that looks like a spring and a weed, so it truly “lives up to its name.” Its leaves spiral upward like a coil. It is a recently emerging small miniature potted plant with a distinctive fresh look, and when it blooms it is very elegant and understated. Placed on a balcony or windowsill, it looks quite nice!

Spring grass, also called spiral grass, gets its name because its leaves twist and coil in the shape of a spring. It is a small ornamental potted plant newly introduced in recent years. Its form is unique and its bulbs are quaint. Depending on the variety, the leaves may resemble springs, drifting kelp in water, curled long hair, or wrought-iron artwork. Its lines are smooth and graceful, full of variation, and its flowers are elegant and fresh. It is suitable for growing in a small pot and placing on a windowsill, desk, or similar spot, where it is unusual and interesting.

Key points for daily care of potted spring grass on a balcony:

1. Four-season management

Spring grass likes cool conditions and fears heat. In winter, 10°C~20°C is best, and it can overwinter safely as long as the temperature does not drop below 0°C. In mid-to-late May, as temperatures rise, the aboveground leaves gradually wither and the plant enters dormancy. The dried leaves can be removed, and the bulb can remain in the original pot to spend the summer. The pot should be placed in a dry, ventilated spot with no standing water. When autumn turns cool, new shoots will emerge from the bulb, and management can slowly resume. During summer dormancy, you may give no water in summer, or keep it slightly moist. The leaves dry up, but the bulb will still grow. Do not pour water into the dry leaf center when watering. After summer, the bulb will grow considerably larger.

2. Light

Spring grass likes light, and during the growing period it should receive sufficient light. If light is insufficient, the leaves will be thin and weak, and the curling will be poor, making it hard to bring out the unique charm of spring grass. Plants grown in full sunlight have low, thick, sturdy leaves that coil and twist, giving them high ornamental value. However, after April, shade netting should still be used to avoid scorching sun and prevent the leaf tips from drying out.

3. Watering

Spring grass likes a moist environment. During the growing period, the soil should be kept moist but not waterlogged. If there is long-term drought and lack of water, the plant will not die, but growth will stall, the leaves will turn yellow, and they may even wither. If the potting soil is waterlogged for a long time, it will cause the bulb to rot. In nice, cool weather, you can frequently mist the plant to increase air humidity and prevent the leaf tips from drying out. In summer, to avoid flooding during the rainy season, the pot can be placed on a rack or on a stand of a certain height, and watering should be controlled to prevent bulb rot caused by standing water. However, the potting soil should not be allowed to dry out completely, lest the bulb dry up.

4. Fertilizing

From October each year to April of the following year is the plant's vigorous growth period. Apply a decomposed dilute liquid fertilizer or compound fertilizer once a month to provide sufficient nutrients and keep the plant growing vigorously. In spring, after the flower stalk emerges, spray with a 0.5% monopotassium phosphate solution 2 to 3 times to promote flowering.

5. Pollination

After spring grass blooms, different plants should be selected for artificial pollination (cross-pollination between different plants) so that the plants set seed. After the seeds mature, take care to harvest them and do not let them scatter. If you do not want to keep seeds, promptly cut off the remaining flower stalks after flowering to avoid consuming too many nutrients.

6. Repotting

Spring grass is generally repotted once a year at the end of August. The potting soil should be fertile and loose, rich in humus, and have good drainage and aeration. It can be mixed from 3 parts leaf mold or peat soil, 2 parts vermiculite or sandy soil, and a small amount of bone meal. When repotting, cut off rotten roots. When planting, leave about 1/3 of the bulb exposed above the soil surface. After planting, water thoroughly and keep it in a spot with sufficient light. Afterward, take care to keep the soil moist, and before long new leaves will emerge from the top of the bulb.

7. Pest and disease control

Spring grass does not have many pests and diseases. The main pests include snails and nematodes in the soil, which harm the bulb. When planting, the soil can be heat-treated to kill pests and eggs in the soil. The main disease of spring grass is bulb rot caused by long-term waterlogging due to poor soil permeability. In addition, drying of the leaf tips can be caused by factors such as dry air and long-term lack of water in the soil. These can be prevented by improving the cultivation environment.

Characteristics of each flowering stage of spring grass and details to note:

1. Early flowering stage

From October each year to April of the following year is the plant's vigorous growth period. Apply a decomposed dilute liquid fertilizer or compound fertilizer once a month to provide sufficient nutrients and keep the plant growing vigorously. In spring, after the flower stalk emerges, spray with a 0.5% monopotassium phosphate solution 2 to 3 times to promote flowering.

2. Approaching flowering

The flower stalk is drawn out from the leaf cluster, forming a raceme. The small flowers hang downward, with the front of the petals pale yellow and the back yellow-green. Some varieties have a light, elegant fragrance. The flowers generally open when there is sufficient sunlight and close in the evening. Opening by day and closing by night in this way, a single flower can remain open for about 5 days. If there is cloudy and rainy weather or insufficient light in the cultivation environment, it will be difficult for it to bloom. The flowering period is from February to April.

3. Characteristics at flowering

Spring grass has a unique form. Depending on the variety, the leaves may resemble springs, drifting kelp in water, curled long hair, and so on. Its lines are smooth and graceful, full of variation, and its flowers are elegant and fresh. It is suitable for growing in a small pot and placing on a windowsill, desk, or similar spot, where it is unusual and interesting.

4. Late flowering stage

After spring grass blooms, different plants should be selected for artificial pollination so that the plants set seed. After the seeds mature, take care to harvest them and do not let them scatter. If you do not want to keep seeds, promptly cut off the remaining flower stalks after flowering to avoid consuming too many nutrients.

After spring grass blooms, the aboveground part will gradually wither and the bulb will enter summer dormant growth. The withered part can be cut off, and the bulb can be left in the pot and placed in a cool, moist place. Water occasionally to keep the soil slightly moist, and the bulb will continue to swell. When autumn arrives, new leaves will sprout. At that point, move it back to the windowsill for normal care.
