Hi all,

Could anyone tell what went wrong with my lavender by looking at the photos? These lavender is about 3 months old. I have been observing that many of the new grow leaves are turning grey.I have try cutting it whenever I see it and even spray copper fungicide on it, however the problem persist. Could anyone tell me what went wrong and solution to it?


By the way I am situated in Pekanbaru a city in Riau province of Indonesia. We have a tropical rainforest climate here with average highest temperature of 30C and an average lowest temperature of 23C. We have summer all year round and we only have wet and dry season throughout the year. Humidity level is high here with around the range of 60% to 98%. I am in low lying area, therefore it is extremely hot here.

Planting lavender may be a challenge here, but don't know for some reason i just want to keep on trying.

Hope from this forum could help me overcome every problem I face when growing Lavender.

Thankyou!

As you probably know, lavender prefers a mediterranean climate - hot, sunny, and it can tolerate dry conditions. I don't have any advice for you, but growing it in a humid, wet climate will probably be the source of any problem you have, with fungal disease being a constant threat.

Are you trying to grow lavender in containers? What kind of soil?

Agreed with Altagardener. What type of lavender is that? and what kind of soil it is currently potted at the moment. It thrives in any poor or moderately fertile, free-draining soils in full sun, and is ideal for chalky or alkaline soils.Lavender can be grown in large pots, 30-40cm (1ft-16in) diameter, using a multipurpose or loam-based compost such as John Innes No 3, with some extra coarse grit, up to 30% by volume, to improve the drainage, and some controlled release fertiliser granules.

Ensure that the compost is regularly watered in summer, but for improved cold tolerance, kept on the dry side during winter by standing in a cold greenhouse or in the rain shadow of walls.

Most lavender can be grown in pots, but it is ideal for tender types - H3 (half hardy) or H2 (tender), such as Lavendula canariensis, L. dentata var. dentata 'Royal Crown' AGM, L. lanata AGM or L. pinnata, which need to be brought undercover during winter and provided with light, well-ventilated conditions.
