Nitrogen deficiencies also cause leaves to remain small, and drop prematurely, resulting in less photosynthesis occurring in the plant, and fewer, smaller tubers can form for harvest. Research done by Yara International has shown that there is a direct correlation between tuber size and yield, and the amount of plant-available nitrogen in the soil.
This species is more tender than common lavender (Lavandula angustifolia), being less frost-resistant, but harsher and more resinous in its oils. Like other lavenders, it is associated with hot, dry, sunny conditions in alkaline soils. However, it tolerates a range of situations, though it may be short-lived.

Decomposition of organic material causes boron to be deposited in the topmost soil layer. When soil dries it can cause a precipitous drop in the availability of boron to plants as the plants cannot draw nutrients from that desiccated layer. Hence, boron deficiency diseases appear in dry weather. [citation needed]
Environmental groups fear that possible study could be the reason lawmakers may push to extend an ongoing pause on any new fertilizer bans, which was approved last summer and runs until July 1 ...
Lavenders flourish best in dry, well-drained, sandy or gravelly soils in full sun. [23] English lavender has a long germination process (14–28 days) and matures within 100–110 days. [24] All types need little or no fertilizer and good air circulation. In areas of high humidity, root rot due to fungus infection can be a problem.
