The soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.5 for healthy growth. The plant is tolerant of saline or alkaline soils but doesn't grow well in waterlogged soil or heavy clay soil.
Cultivation
Euphorbia agraria Bieb. is a shrubby perennial plant that thrives in well-drained soil and full sun exposure. It is moderately drought-tolerant and can survive in varying weather conditions. To grow this plant successfully, you require well-draining soil that is acidic to slightly alkaline.
The ideal temperature range for Euphorbia agraria Bieb. should be between 60-75 °F (15.6-24°C). To promote good growth, avoid planting it in areas with stagnant water, or it will develop root rot disease.
Watering Needs
The watering needs of Euphorbia agraria Bieb. are relatively low. During the first year of planting this plant, it should be watered moderately to establish roots. Once the roots are well-established, the frequency of watering can be decreased. The best way to know when to water is to stick a finger a few inches down in the soil to check if it is dry before watering.
In general, the plant should be watered only when the soil is completely dry. It is better to underwater than to overwater Euphorbia agraria Bieb. because overwatering can cause root rot.
Fertilization
Euphorbia agraria Bieb. requires minimal fertilization. Once every season, apply a balanced fertilizer to the soil around the plant. You can use a 10-10-10 fertilizer by following the instructions on the packaging. Over-fertilization should be avoided because it leads to excessive vegetative growth at the expense of flowers.
Pruning
Euphorbia agraria Bieb. requires minimal pruning. Remove any dead or damaged branches that appear on the plant throughout the year. Do not prune too much because over-pruning can reduce the number of flowers that the plant produces. This plant is not invasive and does not require extensive pruning to manage its growth.
Propagation of Euphorbia agraria Bieb.
There are several methods of propagation for Euphorbia agraria Bieb. that can be used depending on the availability of materials, skill level, and desired outcome.
Seed Propagation
Propagation from seed is a popular method of producing new Euphorbia agraria Bieb. plants. The seeds can be sown in containers indoors or directly in the ground outdoors. It is important to ensure that the soil is well-drained, and the seeds are covered with a thin layer of soil. Keep the soil moist but not waterlogged. The seedlings will emerge in about 10-14 days, and after they have a few sets of true leaves, they can be transplanted to their permanent location.
Cuttings Propagation
Euphorbia agraria Bieb. can also be propagated from cuttings. Cuttings can be taken from the stem of the plant, and they should be about 4-6 inches in length. Remove the lower leaves from the cutting, and allow the cutting to dry for a day or two. Then, dip the cut end in rooting hormone before planting it in well-drained soil. Keep the soil moist but not waterlogged, and the cutting will develop roots in about 4-6 weeks.
Division Propagation
Euphorbia agraria Bieb. can also be propagated through division. This method is best used for mature plants that have multiple stems or offsets. Dig up the plant and separate the stems or offsets, making sure each has some roots. Replant each stem or offset in well-drained soil, water thoroughly, and keep the soil moist until new growth appears.
Disease and Pest Management of Euphorbia Agraria Bieb.

To manage leaf spot on Euphorbia Agraria Bieb., remove the affected leaves and dispose of them. You can also use a fungicide to prevent the spread of the disease.
5. Aphids
Aphids are small, green or brown insects that can suck the sap from the leaves, causing them to curl and turn yellow. They can also transmit plant diseases. To manage aphids, you can spray the plant with a strong stream of water to dislodge them. You can also use insecticidal soap or neem oil to kill them.
