Flower, Vegetable, Herb & Green Manure Seeds
In this post, you’ll find out the seeds per gram for popular flower, vegetable, herb and green manure seeds.
It is important to note that the seeds per gram can vary widely, even in the same species. For example, tomato seeds can have 250-400 seeds per gram, depending on variety.
The term ‘seeds per gram’ is used as an approximate value as weight can vary depending on environmental and storage conditions. These values can vary from year to year, with natural variations, and between seed lots. Adjust seeding rates after conducting your own trials.
This handy guide will give you an indication of what to expect in terms of seed sizes.
- Brassica species are small seeds (e.g. cabbage, broccoli, kale, bok choy, chinese cabbage) with approximately 300 seeds per gram, and 300,000 per kg.
- Cucurbita species are large seeds (e.g. pumpkin, squash, and gourd) with approximately 8-10 seeds per gram, and approximately 8000 – 10,000 per kg.
