Pruning
Pruning is not necessary for Eschscholzia lemmonii Greene ssp. lemmonii, as it has a naturally compact growth habit. However, deadheading spent flowers will promote continued blooming and prevent the plant from self-seeding.
To deadhead, simply cut off the faded flowers at the base of the stem. This will encourage the plant to produce new flowers and prevent the development of seed pods.
In conclusion, following these cultivation methods, watering needs, fertilization, and pruning practices can ensure healthy growth and blooming of the Eschscholzia lemmonii Greene ssp. lemmonii.
Propagation of Eschscholzia lemmonii Greene ssp. lemmonii
Eschscholzia lemmonii Greene ssp. lemmonii, also known as Lemmon's poppy, is a beautiful perennial wildflower that originates from California and Nevada in the United States. The plant has gray-green foliage and produces bright yellow to orange flowers on top of long stems. Propagation of this plant can be done through several methods that are suitable for different scenarios.
Propagation by Seeds
Propagating Eschscholzia lemmonii Greene ssp. lemmonii by seeds is the most common method since the plant produces a lot of seeds that are dispersed naturally. The best time to collect the seeds is when the capsules dry and start to open, revealing the black seeds inside. The collected seeds can be stored in a cool, dry place until the following year's planting season.
Sowing the seeds is best done in the spring, after the last frost. The soil should be prepared by removing weeds and rocks and be tilled to a depth of 2 to 3 inches. The seeds should be sprinkled on top of the soil and covered with a thin layer of soil. The soil should be kept moist, but not soaking, until the seeds germinate, which usually takes 5 to 14 days.
Propagation by Division
Division is a method of propagation that is best suited for mature plants that have grown too large or have become less productive in terms of flowers. It is best done in the spring or fall when the plant is not flowering. To divide the plant, the soil around the plant should be moistened to make digging easier. The soil around the plant should be carefully dug, and the root system should be gently lifted from the soil.
The root system can be separated into smaller sections by using a sharp, sterilized knife or spade. Each section should have at least one shoot and several roots. The separated sections should be planted in prepared soil and kept moist until new growth appears, which may take a few weeks.
Propagation by Cuttings
Propagation by cuttings is a method best suited for indoor planting. To propagate by cuttings, cut a 6-inch piece of stem from a healthy plant, stripping off the leaves from the bottom 3 inches of the stem. Dip the cut end of the stem in rooting hormone powder. Insert the cutting into a pot filled with soil mix and gently tap down the soil around the stem. When roots have formed, usually within a few weeks to a month, transplant the cutting into a new container or outside into the garden.
Eschscholzia lemmonii Greene ssp. lemmonii is a beautiful and easy-to-grow plant that can be propagated effectively through different methods. With the right care, propagation can lead to a large and flourishing bed of these lovely flowers.
Disease and Pest Management for Eschscholzia lemmonii Greene ssp. lemmonii

Here are some common diseases and pests that might affect the plant, as well as ways to manage them:
Diseases
Fungal Diseases: Lemmon’s poppy can be susceptible to fungal diseases such as powdery mildew and root rot. Powdery mildew is a white, powdery coating on the leaves and stems that can impede photosynthesis and weaken the plant. Root rot is caused by overly wet soil and can lead to decay of the plant’s roots. To manage these fungal diseases, avoid overhead watering and improve air circulation around the plant. Remove affected leaves and stems and dispose of them properly, and use a fungicide if necessary.
Bacterial Diseases: Bacterial leaf spot is a common bacterial disease that can cause circular brown spots on the leaves of Lemmon’s poppy. This disease can be spread by water, insects, or contaminated equipment. To manage bacterial diseases, remove affected leaves and disinfect pruning tools between cuts. Use copper-based fungicides in the early stages of the disease.
Pests
Aphids: Aphids are a common pest that can feed on the sap of Lemmon’s poppy, causing wilting and stunted growth. These insects can be controlled with insecticidal soap or neem oil. Encouraging natural predators such as ladybugs and lacewings can also help to reduce aphid populations.
Snails and slugs: Snails and slugs can feed on the leaves and stems of Lemmon’s poppy, leaving behind ragged holes and slime trails. To manage these pests, remove any debris near the plant that may provide hiding places for them. Handpick and dispose of snails and slugs, or use organic controls such as iron phosphate granules.
Spider mites: Spider mites are tiny insects that can suck the sap from the leaves of Lemmon’s poppy, causing yellowing and wilting. To manage spider mites, wash the plant with a strong spray of water to knock them off and encourage natural predators such as predatory mites, ladybugs, and lacewings. In severe cases, use insecticidal soap or neem oil according to label instructions.
By being vigilant about disease and pest management, you can help keep your Eschscholzia lemmonii Greene ssp. lemmonii healthy and thriving.
