Planting Seedlings in Compost: When and How to Do It Correctly

Introduction

The use of compost in gardening is a popular and effective practice for enriching soil and promoting plant growth. However, many gardeners wonder whether they can plant vegetable seedlings directly after applying compost. This article delves into the nuances of when and how to plant seedlings in compost, ensuring a bountiful harvest.

When Can You Plant Seedlings in Compost?

It is essential to ensure that the compost is well-rotted and cooled before planting seedlings. This process typically takes several weeks to a few months depending on the composting method. If the compost is still actively decomposing or 'hot', it can burn the seeds and young plants, leading to poor germination and stunted growth.

Expert Tips: Cooling and Rotten Compost: Compost that has completely finished its decomposition and reached a proper temperature is ideal. This compost is nutrient-rich and provides an excellent environment for seedlings. Double Digging: For large-scale planting, double digging the soil and adding a shovelful of compost before blending it in can significantly improve soil quality and seedling growth. Season Extension: Warmer compost in the fall can help extend the growing season for crops like lettuce, extending their productive phase even in colder weather with some protection.

Can You Plant Seeds Directly in Compost?

Yes, you can plant seeds directly in compost. However, it is crucial to ensure the compost is well-rotted and not still actively composting. Unfinished or 'warm' compost can burn the seeds or young seedlings, leading to poor germination and stunted growth. By providing a ready-to-eat food source for your plants, compost can enhance soil fertility and plant growth.

Compost as a Top Dressing

Compost also serves as an excellent top dressing, providing a continuous supply of nutrients to the soil and plants. Applying compost as a top dressing in the spring can help nourish seedlings and promote healthy growth. The method of side dressing with a scant handful of compost, followed by gentle incorporation with a trowel or hand cultivator, is an effective technique.

Conclusion

Planting seedlings in compost is a viable and beneficial practice if done correctly. Always ensure the compost is well-rotted and not still actively decomposing to avoid burning the seeds and young plants. By following these guidelines and expert tips, you can enjoy a thriving garden season after season.
