Poppy – Downy mildew
Symptoms occur as angular, chlorotic to necrotic spots on the upper leaf surface, distorted growth and eventually a purplish, downy growth on undersides. High humidity, prolonged leaf wetness, and cool weather favor the development of Downy Mildew diseases.
Poppies do not like soggy soil, and some gardeners report that overly-rich soil can lead to a lack of flowering. On the other hand, your soil may be lacking nutrients necessary for flowering. Check with your local nursery for a fertilizer that is specific to Read more

Poppies typically spread through seed formation. The flowers die back and yield seed pods that mature in summer. Many poppies, like California poppies, take root easily. They quickly spread across a hillside and may yield several generations in a season.
Poppies will grow well in either a sunny or partially shaded position. Annual and biennial poppies will grow in a wide range of soils, including very poor and even stony ones, where little else grows well. The perennial, Oriental poppies prefer deep, fertile, well-drained soils.
The brightly colored, 8- to 9-inch-wide flowers appear in May and June, attracting bees and butterflies to the garden. When hot weather arrives, the plants die back until cooler weather arrives. In the fall, new foliage appears and in mild winter climates continues to grow Read more
The simplest answer, if you are new to growing oriental poppies, may be that you haven't yet gotten to their flowering season. Poppies do not like soggy soil, and some gardeners report that overly-rich soil can lead to a lack of flowering. On the other Read more

The typical leaf curl symptoms in poppy plants suggest that the infection has been caused by begomovirus, which was confirmed by PCR analysis using begomovirus degenerate primers (Supplementary Table S1).
Dry conditions and excessive shade expose poppies to powdery mildew infection. The easily identifiable disease conceals the leaves beneath talcum-textured, white fungal mats.
Generally, young puppies need about one-half cup of water every two hours. You'll want to monitor your puppy to make sure he's drinking enough . . . and not too much. Older puppies that have already been weaned generally need between one half ounce and Read more

Dry conditions and excessive shade expose poppies to powdery mildew infection. The easily identifiable disease conceals the leaves beneath talcum-textured, white fungal mats. Powdery mildew is most likely to strike at temperatures between 60 and 80 degrees Fahrenheit.
Watch That Water Waterlogged soils force poppies to languish, causing root death that forces foliage discoloration and death. Excessive moisture around the poppy crown and roots also renders the plant vulnerable to fungal root or crown rots.
Annual poppies cannot withstand frost. Some perennial poppies are also intolerant of frost and are generally grown as annuals in cold-winter areas. Other perennial varieties tolerate cold weather.
poppy seeds are sustainable. Poppy seed production is relatively sustainable since there is no known significant damage to air, water, land, soil, forests, etc. as long as pesticides have not been used.
Annual poppies come back every year when you leave the spring blooms on the plant so they can drop their seeds. Perennial poppies form neat, spreading mounds, while letting the plants reseed themselves leads to chaos in beds and borders.
Crude poppy material at any dose is highly poisonous. The alkaloids are extremely toxic and can cause convulsions, asphyxiation, and death.
Poppy seeds are good sources of protein and dietary fiber, as well as some essential vitamins and minerals, including calcium and magnesium. Poppy seeds are small, black, and kidney shaped. They have been part of traditional Mediterranean and Middle Eastern diets for thousands of years.
Your poppy will always need full sunlight and well-drained soil.
Common poppy has medicinal uses including as a mild sedative. Poppies are usually insect-pollinated, however, the species is more or less self-fertile and, as the anthers dehisce before the flowers open, self-pollination can occur ahead of cross-pollination. Seed ripens and is shed 3-4 weeks after Read more
Caring for poppies Annual poppies are easy to care for. There's no need to stake or deadhead the plants – just let them flower and seed as part of a wildflower display. A poppy flower will last for about 10 days but plants will have Read more
Poppies need at least 6 hours of sun. Some varieties of poppies grow very large, up to 5 feet tall. Plan accordingly and plant poppies where they will have room to grow. Many varieties of poppies reseed easily.
Poppies come in perennial and annual varieties. Perennials include iceland poppy (Papaver nudaucaule), oriental poppy (P. orientale) and alpine poppy (P. alpinum).
The roots of most poppy plant varieties only grow down into the soil 2 or3 inches, but can grow outward as far as 10 inches to 12 inches.
Rhizoctonia Root Rot Midsummer is the time to inspect your poppies for signs of Rhizoctonia root-rot infection (Rhizoctonia solani). This soil-borne fungus penetrates poppy roots, decaying them from firm and white to mushy and black. It may also penetrate the stems, causing dry rot at Read more
As far as the plants are concerned they're ready to go, they're sending up flower stems everywhere. I've been pinching out poppy flowers for the last week or so. This is simply to encourage all the plants to grow to a decent size before I Read more
When & How to Plant Poppy Seeds Directly sow poppies outdoors in early spring even if threat of frost still exists. Poppies are frost tolerant and germinate best in cool weather and soil, sow your poppy seeds as early as the ground can be worked.
Dig a hole as deep as the root system and twice as wide. Put the plant in so that the top of the roots are level with the top of the soil. Basically you want it to sit just as it was sitting in its Read more
All parts of poppies can be harmful to cats if ingested. The amount of alkaloids or opioids can vary, depending on the species, but all have potential to harm your cat. Symptoms of poisoning include dilated pupils, difficulty walking, lack of appetite and coma.
Poppy seeds are particularly rich in manganese, a trace element important for bone health and blood clotting. This mineral also helps your body utilize amino acids, fats, and carbs ( 4 ). They're likewise high in copper, a mineral needed to make connective tissue and Read more
Thus the ideal conditions are snow in winter, rain in spring and dry weather while the plant is mature. As the poppy cannot stand extreme cold, it cannot be cultivated in frosty climates unless there is a sufficient covering of snow in winter to protect Read more
