This is important that we buy saffron bulbs where, when, and from who. In other words, the most critical part of our investing is done on buying saffron seeds, and if we don’t care about it, our investment will fail soon.

In this post, we will answer all of your questions about saffron Crocus bulbs and their properties. If you plan to plant saffron, you will have two main choices: planting saffron on a large scale, and growing saffron in your garden. In both cases, we have helpful suggestions for you.

To grow saffron professionally, you should buy “1 kg saffron corms per 1 square meter” and plant them 20 cm deep. Each bulb can produce some saffron flowers, and each flower can make three saffron stigmas.

The first time I bought Crocus Sativus seeds, I was thirteen years old, and I didn’t have any information about how to maintain or plant bulbs in the soil, so saffron bulbs were spoiled soon. It’s better to get some info before buying saffron Crocus bulbs.

Saffron bulbs features

The best criterion for classifying saffron Crocus bulbs is their size. We should have a strategy for our saffron farm, and we should buy saffron bulbs based on that strategy. Sometimes we need to harvest a lot of saffron in the first year of cultivation to cover our expenses.

In this case, we can buy large size bulbs, and they will flower well in the first year.

On the contrary, sometimes we want to have a lower cost for buying bulbs; we can buy smaller bulbs and wait for the second year. When we have medium or small bulbs, our bulbs commonly can’t bloom in the first year, and we should wait for the following year.
