Celery germination in the summer heat is a relatively difficult task, because celery is a cool-season vegetable and is more adapted to low temperatures and high humidity. However, you can try the following to help celery germinate in the summer heat:
1.Early germination: Before the summer heat, celery seeds can be pre-germinated in early spring or early fall. Place the seeds in a moist paper towel or cotton, place them in a warm place, keep them moist, and wait for the seeds to germinate before transplanting them into a pot or flower bed.
2.Refrigerate seeds: Place celery seeds in a plastic bag, seal them and refrigerate them for 2-3 weeks. The seeds are then taken out, gradually warmed back to room temperature, and sown in moistened medium. This method can simulate the "dormant" state of celery seeds in the spring at low temperatures, providing an opportunity to germinate at high temperatures.
3.Shade and moisturizing: Shade is an important way to help celery sprout during hot summer temperatures. Shade nets, shade panels or shade can be used to shade the sun and reduce temperature increases. At the same time, keep the seed sowing medium moist, spraying water regularly using a spray bottle to maintain humidity.
4.Use shading and cooling facilities: Building awnings, greenhouses, or cooling facilities in rooms or patios, such as water spray systems, fans, etc., can help control temperature and humidity and provide a more suitable environment for celery germination.
In conclusion, celery germination at high temperatures in summer is a challenging task, but the success rate of celery germination in high temperature environments can be increased by methods such as early germination, seed refrigeration, shading and moisturizing, and the use of shading and cooling facilities.
