![]() ![]() It is suggested that you lay snail pellets around the plants on the same day they are transplanted to the garden in order to defend them from pests. The most significant issue is that slugs, snails and aphids harm the plants when they are young and vulnerable seedlings. This usually implies that they should be planted in the middle or rear of the border.Ĭosmos are a relatively hassle-free species to cultivate, with few health or pest issues if grown in the correct way. The Cosmos may grow as little as 1ft tall to 3ft high depending on the type. BloomingĬosmos are appropriate in cottage gardens where they create lots and lots of blooming flowers. If you’re growing Cilantro at home, you might have noticed seedlings falling over continuously. Cosmos seedlings should be spaced 12 to 15 inches apart, and thick mulchshould be applied to the ground to aid in water retention. If your soil is poor, add compost to improve its nutrient levels. ![]() Planting them in the garden is best done in a warm, sunny location with adequate, moist soil that is well-drained. This mimics weather conditions in order to encourage the plant to produce a thicker stem and better withstand this kind of environment.Ĭosmos seedlings are sensitive to temperatures below 57.2 Fahrenheit (14☌) and can be damaged by frost for prolonged periods of time. The second approach is to utilize a fan and blow a gentle breeze toward them. The first method is to brush your hand against the leggy cosmos seedlings once or twice a day, which provides the plant with some resistance. So what can we do to force these leggy seedlings to grow stronger and sturdier? There are two ways: So we’ve established that l eggy cosmos seedlings are not sturdy enough to withstand things like natural weather such as strong winds and rain. This is absolutely fine, I just continue to increase the height of the heat lamp whilst making sure that the source is still 2.5 inches above. You may find that you will need to continually increase the height of your artificial light as the cosmos seedlings grow taller. Remember if you have opted for artificial light, it is important that your light is close enough to the seedlings so they can soak up as much of it as possible for photosynthesis. If you are concerned about not being able to provide them with enough natural light, you can supplement them with artificial fluorescent bulbs placed within 2.5 inches of your seedlings. Without adequate sunlight, you will put your seedlings under unnecessary stress, which will, in turn, cause them to become leggy or worse, wilt and die. So the absolute number one focus needs to be that you are ensuring that your seedlings are getting enough light. I find indoors that a light breeze also helps prevent the tall and weak stems. ![]()
