If grown indoors, you can plant it in a pot with well-drained soil and place it near a window that receives plenty of sunlight. Outdoors, you can plant it in your garden after preparing the soil by adding compost to improve its fertility. It is best to plant Euphorbia lurida Engelm. during the spring season so that it can establish itself before the hot summer months begin.
Watering needs for Euphorbia lurida Engelm.
Euphorbia lurida Engelm. is a drought-tolerant plant, and overwatering can harm it. It is thus important to water the plant only when the soil is dry. These plants can survive for days without being watered.
When watering the plant, it is best to water the soil gently and not the leaves or the stem to avoid causing stem rot or leaf spots. You can also add mulch to the soil to help retain moisture and minimize evaporation.
Fertilization requirements for Euphorbia lurida Engelm.
Euphorbia lurida Engelm. is not a heavy feeder and requires little fertilization. During the growing season, you can apply a balanced fertilizer once a month to help it grow better. Avoid fertilizing during the winter season, as the plant is dormant during this period.
You can also supplement the soil with compost or well-rotted manure to help improve soil fertility naturally.
Pruning Euphorbia lurida Engelm.
Pruning Euphorbia lurida Engelm. is not mandatory. However, if you notice that the plant has grown unruly or has become too tall, you can prune the stem back to a height where it looks tidy and attractive.
Use a pair of clean, sharp shears to prune the plant, making sure you wear gloves as its sap can be mildly toxic and can cause skin irritation. Additionally, cut back overgrown stems once the plant has finished flowering, which usually occurs in late fall.
Propagation methods of Euphorbia lurida Engelm.
Euphorbia lurida Engelm. is a herbaceous species that belongs to the family Euphorbiaceae. This plant species can be propagated by various methods such as:
1. Seeds propagation
The most common way to propagate Euphorbia lurida Engelm. is by using seeds. The seeds of this plant species can be sown in moist soil in the early spring. The seeds should be sown about ¼ inch deep and watered regularly to keep the soil moist. The seeds will germinate within one to two weeks, and the seedlings can be transplanted outdoors once they have grown to about 2 to 3 inches tall.
2. Stem cutting propagation
Euphorbia lurida Engelm. can be propagated by stem cuttings as well. Cuttings should be taken in the early summer. Take a 3 to 4 inches long cutting from a healthy plant with a sterile, sharp knife. Dip the cut end in rooting hormone powder and embed the stem in well-draining soil. Cover the pot with a clear plastic bag to maintain humidity, and place it in a bright location out of direct sunlight. New roots will emerge within a few weeks.
3. Division propagation
This Euphorbia species is also propagated through division in the early spring. Divide the mature clumps into smaller sections, making sure each section has a good amount of roots attached. Replant the new sections in well-draining soil and water thoroughly.
