Ginseng Crop Update – Pest Management During Emergence – May 13, 2022

With the sudden switch to summer-like weather and plenty of sunshine to heat up the soil, ginseng is rapidly emerging this week. More humid weather is expected over the weekend, and this will increase the risk of foliar diseases, especially Alternaria. The current forecast suggests rainfall amounts will be relatively light Sunday and Monday, which should keep the risk of foliar Phytophthora lower, but a thunderstorm accompanied by even a brief period of heavy rain could increase the risk.

Lavender Crop Update – Green-Up of Plants – May 13, 2022

The warm weather over the past week should lead to rapid green-up of lavender plants. Plants without any winter kill should be obviously green with new shoots beginning to expand at the tips. For other plants, recovery from winter kill has been slow, mainly due to colder than normal weather in April and the first week of May. There have been many concerns raised by growers about uncovered angustifolia cultivars that appear to be severely damaged or even killed. ‘Super Blue’ appears to be particularly damaged.  A couple of weeks ago I suggested these will likely come back from the base and along the stems if the stems are still green inside. While I expected a more rapid recovery and shoots emerging all along the green stems, it still appears that plants will come back at the base, even if recovery along the stems is not as expected.

Ginseng Crop Update – April 29, 2022

Ginseng emergence continues to be slow compared to last year, which probably protected the plants from significant freezes the last two nights. Looking at Growing Degree Days (GDD) Base 5°C for the spring up to April 30 at Delhi (including the forecast for tomorrow), we will likely have accumulated around 100 GDD this year. Last year, we had accumulated 170 GDD by April 30. At this time of year, it is normal to accumulate around 5 GDD per day, which means crop growth is likely around 14 days behind last year.

Assessing Crop Progress and Winter Kill – Lavender Crop Update – April 28, 2022

This is usually the most stressful period for lavender growers. Everything else is turning green but the lavender is still looking grey in many cases, which can often lead to the conclusion that the plants have suffered severe winter kill. It is generally too early to determine the full extent of winter damage but there are a few clues that growers can use to reduce fears of total crop loss.
