What is the most challenging herb to grow?

The difficulty of growing herbs can vary based on several factors, including local climate, soil conditions, and care practices. However, some herbs are generally recognised as being more challenging to cultivate than others, especially for beginners. Here are a few that are often considered more demanding:

1.    Stevia (Stevia rebaudiana): It can be a bit tricky because it requires specific light conditions to grow well and has particular temperature preferences. Stevia doesn't tolerate cold well and requires well-draining soil.

2.    Tarragon (Artemisia dracunculus): True French tarragon can't be grown from seeds. Instead, it needs to be propagated from cuttings or by root division. It also prefers specific conditions—well-drained soil and not too much water. It should also be kept dry over winter.

3.    Saffron Crocus (Crocus sativus): While not a herb in the traditional culinary sense, saffron—the world's most expensive spice—is derived from the stigmas of this flower. It requires a specific climate and soil type and is labour-intensive to harvest.

4.    Lavender (Lavandula spp.): While lavender is grown widely, achieving the ideal conditions can be a challenge. It thrives in well-draining soil and requires plenty of sunlight. Overwatering or planting in heavy soils can lead to root rot.

5.    Wasabi (Wasabia japonica): Though it's not a common garden herb and more of a speciality plant, wasabi is difficult to grow. It prefers cool, humid conditions, and it takes about two years to mature. In its natural habitat, it grows along stream beds in Japan's mountain regions.

6.    Sweet Bay (Laurus nobilis): The Bay is a tree rather than a typical garden herb, but it can be grown in pots. However, it can be slow-growing and is sensitive to wind and extreme temperatures.

7.    Parsley (Petroselinum crispum): While not exceptionally challenging for everyone, some gardeners find parsley seeds can take a long time to germinate and require specific conditions to do so. Parsley also likes a rich, moist soil, so plenty of water is needed to help it thrive.

 

It's essential to note that "challenging" is relative. What might be tricky for one person in a particular environment might be straightforward for another in different conditions. If you're interested in growing any of these herbs, it's worth researching their specific requirements and consulting local gardening experts or resources to optimise your success.
