Lamium

Lamiums require regular, consistent watering without over-watering. Generally, they should be watered when the top 2-3” of soil is dry, or about once every 3-4 days. During the hotter months they may need to be watered more often, and in the winter they may be watered less often. Make sure you check the soil moisture before deciding if they need to be watered.

Lamiums prefer part shade or even full shade but can adapt to full sun if given extra attention to its watering habits. Lamiums are not able to tolerate too much direct sun however, and if provided too much they will become stressed and have problems producing foliage and flowers. During the summer months, it is best to provide indirect sunlight or shade for your Lamiums to protect them from the intensity of the sun and help keep up their growth.

Lamiums prefer moderate temperatures between 60-75°F (16-24°C). They can tolerate extreme temperatures if they are mild and don't last long, but if they get too cold they may die. High temperatures can cause their leaves to wilt and drop off, and sudden temperature changes should be avoided.

Lamiums prefer humid conditions, though they are able to tolerate any levels of humidity. High humidity will help keep their leaves and flowers looking fresh and healthy, so misting them occasionally or placing them near a humidifier is recommended.

Lamiums prefer a well draining soil mix that is slightly acidic and contains organic matter. A mix of peat, sand and loam is ideal, as it will ensure that nutrients are available to the plant while still allowing the necessary drainage. Fertilizing with a balanced fertilizer can also be beneficial to the health of your Lamium.

Lamiums should be fertilized once a month during the growing season, from late spring to early fall. A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium should be used. Avoid fertilizing the plant during the winter months as this can lead to over-fertilization.

Lamiums are generally resistant to most common plant pests, but there are a few that can be an issue for them. Aphids and spider mites are the most common pests that affect Lamiums, and both are spread by contact with other affected areas. Treating lamiums with an insecticidal soap is recommended to treat any possible infestations as soon as possible. If left untreated, they can cause damage to the leaves and flowers of the plant, so keeping them regularly lookout for changing foliage is recommended.

Lamiums should be repotted once a year in early spring to encourage healthy growth. If the pot has grown too small for the roots of your Lamium, repot it in a container one size larger and also change the soil. Use a new potting mix that is specially made for flowering plants.

Pruning is not necessary for Lamiums, but can be done occasionally if needed. They tend to become overgrown in time and need to be pruned back to keep them looking neat and tidy. Pruning should be done in early spring once the plant is out of its dormant period.

Mulching is not necessary for Lamiums but can be beneficial for retaining moisture and providing extra nutrients to the plant. A layer of bark mulch or compost can be added to the soil to provide extra protection from overwatering and to help regulate the soil temperature.

Lamiums can be propagated either from cuttings or by division. To propagate from cuttings, take a softwood cutting in late spring to early summer and remove all but the top two leaves. Dip the cutting in a rooting hormone and place it in a potting mix. Keep it in indirect sunlight and keep the soil moist. By division, a mature Lamium can be dug up and its crown split into several parts with a sharp knife. Replant the pieces in separate containers with fresh soil and water them regularly.

If needed, a tall stake can be used to provide support to your Lamium during its growth period. It should be planted deeply and the stems of the plant can be securely tied to it with soft string or twine.

Lamiums usually go into a dormant state in the winter and their growth will slow down. Water them less frequently and avoid fertilizing during this period to give them a chance to rest from the summer months.

Most varieties of Lamiums are not toxic to pets, but there are some exceptions. If in doubt, it is best to consult your veterinarian before introducing one into a home with pets.
