Leafy Green

Leafy green plants appreciate consistent and frequent watering during the growing season. The soil should be kept moist but not soggy. In drier climates, adding a layer of mulch to the top of the soil can help to conserve moisture. In cooler climates, supplemental watering may be necessary. During the dormant season, water less often but be sure to check for signs of drought stress and water if necessary.

Leafy greens enjoy full sun or part shade. As a general guideline, those that prefer full sun will tolerate lower light but those that prefer part shade won’t do as well in full sun. Full sun plants like Coleus and Iresine, do particularly well in bright indirect light, while part shade plants like Acalypha and Mazus will be harmed by too much sun. Choose the right plant for the right light and follow the instructions of the particular species as some may have unique needs.

Most leafy greens prefer warm to moderate temperatures, ranging from 65° to 75°F. Some may require cooler temperatures, especially in summer, while some may need higher temperatures in winter. Be sure to check the temperature requirements of each particular species before planting.

Leafy greens prefer moderate humidity levels, between 40-60%. If your home is especially dry, consider using a humidifier to increase humidity and to help the plants thrive.

Leafy greens prefer well-draining, organic soil that contains plenty of nutrients such as nitrogen and potassium. The soil should also be loamy with a slightly acidic pH. Adding compost, aged manure, and organic matter can help to improve the soil quality.

Leafy greens will benefit from regular fertilizing during the growing season. Reapply fertilizer every four to six weeks and avoid over-fertilizing. Use organic or slow-release fertilizer and be sure to follow the instructions on the label. During the dormancy period, avoid fertilizing.

Leafy greens are susceptible to a variety of pests, such as aphids, mites, thrips, mealybugs, and scale. Inspect your plants regularly and treat with an appropriate product if any pests are found. Neem oil and insecticidal soap are useful for controlling a variety of pests. Regularly remove any dead or dying leaves or stems as these can be attractive to pest insects.

Leafy greens should be replotted after about two years or when growth is limited. If the pot is too small or too large, it may cause the growth of the plant to be stunted. Select a pot size appropriate for the particular species and use a soil that drains well. Be sure to water the newly planted plant thoroughly and periodically check for root problems by gently removing the plant from the pot.

Leafy greens will benefit from occasional pruning. This should be done on an as-needed basis, as certain species may need frequent pruning to look their best. Pinching or trimming of stems can be done to encourage branches to branch and for larger plants, prune out any old, dead growth for healthier, new growth. Do not over-prune or “shear” a plant as this may damage it.

In areas with hot summers, a layer of mulch should be added to the soil around the plants. This will help to conserve soil moisture and moderate soil temperatures during the hot summer months. Use organic, non-toxic materials such as wood chips or straw for best results.

Leafy greens can be propagated in several ways, such as cuttings, division, and layering. Cuttings can be taken in early spring or summer, while division may be done in early spring or fall. Layering can use a stem that has a few set of leaves, and this is done by bending the stem and burying it into the soil and keeping it in place until it takes root. Keep the soil well-moistened and be sure to allow enough time before transplanting the new growth.

For taller plants, provide support using stakes or trellises. This will help to prevent damage from broken stems due to strong winds or rain. Use appropriate materials such as bamboo or metal and make sure that the plant is securely tied to the support for stability.

Leafy greens may require a rest period in late winter or early spring. During this time, they should be cut back and allowed to “rest” before new growth begins. This will help them produce more healthy new growth in the spring.

Leafy greens can be toxic to pets if ingested. Be sure to keep all leafy greens away from pets and supervise them closely if they are in the same area.
