How to grow asparagus fern and what to do when the leaves turn yellow
How to grow asparagus fern: it likes warmth and should be placed in a sunny spot in winter. If it is kept for a long time in winter in a place with no light, poor ventilation or cold, the branches and leaves easily turn yellow and wither. At this point you can move it to a warm place with sunlight, keep the room temperature between 12°C-18°C, control watering appropriately, and it can gradually return to normal.
Asparagus fern is sensitive to smoke and dust; if it encounters toxic gas, the branches and leaves easily turn yellow. For this reason, when caring for it, take care to place it in a clean environment. Asparagus fern likes fertile soil; if the soil is not changed and fertilizer not added for a long time, the nutrients cannot meet demand, and yellowing of branches and leaves will appear. At this point, water once a week with rotted dilute liquid fertilizer or compound chemical fertilizer, and water and loosen the soil in time, and it will soon turn from yellow to green. If the fertilizer is too concentrated or unrotted fertilizer is applied, it easily causes "root burn," leading to dry, falling leaves. At this point, you need to take the plant out of the pot and remove the fertilizer, rinse the root ball with clean water, and then replace it with new potting soil.
Asparagus fern likes partial shade and dislikes strong light. If it is placed in direct sunlight in summer, the branches and leaves very easily wither and yellow. At this point, move the pot to a shady place and frequently spray water on the branches and leaves to increase air humidity; when the damage is light, most can recover to their original state.
How to grow asparagus fern: it likes moisture and fears drought, and dislikes excessive moisture and waterlogging. It has fairly strict requirements for soil and water, and mastering the appropriate potting soil moisture is a major key to the daily care of asparagus fern. If watered too much at ordinary times, causing the potting soil to stay too wet or waterlogged for a long time, it will cause poor root growth and then root rot. This shows above ground first as leggy branches and leaves, then yellowing leaf tips, branches and leaves gradually withering and yellowing, and leaf drop; newly grown tender shoots wither partway, and vines over three years old show heavy flower and seed drop, and in severe cases the whole plant can die. If watered too little, the potting soil becomes too dry, causing yellow leaves and withered tips, small branches falling off, a shrunken appearance, and bud and flower drop. Therefore the potting soil should always alternate between drying and moistening. If you find the potting soil too wet, do not continue watering; instead loosen the soil, repot, and clear the drainage holes to help excess water drain away quickly.
