Beloved Lavender bushes dying

Dear All, We have five lavender bushes all about four years old. I deadhead and use the flowers daily and the bushes flower all year round (we are in the middle of the Atlantic Rainforest outside Rio). After temps of up to 40deg and torrential rains they are mostly brown and grey and toppling over after the weight of the rain (and bad drainage-system on the house). Any advice or is all lost? They are very dear to me and my grandmother back in England! Many thanks. ps i don't know how to attach a pic as i am new to this. Happy gardening!

  • Lavender likes hot dry conditions with sharp drainage so it sounds as if your plants are struggling with the wet. What can you do to improve the drainage? If there are any live plants you could take some cuttings as an insurance policy should you lose any plants. My lavenders also seed readily ... have you any seeds or seedlings at the base of the plants, which you could pot up and bring on for the future. Your climate is so different from ours that it is difficult to know what to do. Good luck with them.

  • Thanks WW. I think you are right re. the water.The house drainage is a major problem to be fixed one fine day!!! I will endeavour to take cuttings this weekend, do you know what soil mix is the best as when i tried before none of them sprouted roots. The climate here and the Ps&Ds that come with it are a challenge but part of the life long lessons i guess. Thanks again and Happy Gardening! 

  • Again you want sharp drainage. Try a mix of potting compost and grit . Place cuttings around edge of pot which is supposed to increase chance of striking. Do several pots with about 6 cuttings in each. Water then put in shade. I wouldn't put plastic bags over them in your circumstances since they should have fresh/dry air to avoid rotting off. Water about once a week. Stand pots on sand/gravel. Good potting.

  • Thank you so very much for your detailed advice. I will do just that this weekend, suprised about the watering just once a week. many many thanks for the expert tips.

    Some years ago I was asked to help with the garden design for a hotel in the Carribean; after talking to experts I learnt that plants like Pelagoniums would not do well in that climate as they need a 'down' season, which they get in their native South Africa and the South of France, but not in Barbados where the winter temperatures are too high. The only roses that seem to survive there are some special ones from Thailand I believe. You may need to do some research on the exact conditions that lavender enjoy and change the type of lavender to suitimage

  • Thanks Artjak but this type of lavender (Angustifolia) thrives in the mountains here, it was the pride of the garden before the rainfall this summer which was 7 times the usual volume on just one day. We are 900m up and really do have cool temps at night. Think it really is a case of sorting the drainage ready for next year and the sharp drainage as per WW. We have many roses too, the land is very fertile clay based so much work is needed introuducing more well drained soil. Just wish we had more time as we are in Rio mon-thurs and im too stubborn to employ somebody to help!! You work in the Carribean must have been a joy. Many thanks for the advice however and good luck on your next ventures!

    Pean, I really hope your Lavenders survive. If you want an under gardener I'm available, have loved hols in Caribbean. Bet you grow some wonderful statuesque plants. Would be great if at some time you could post some pictures.

  • What a lovely, kind offer! I have probably 23561 questions to be honest! I have many pictures of some very statuesque plants of which many are suffering due to climate change and me being an amateur! Do you know how i post pics? It's proven to be a lifeline and my great passion here but there is so much to do!
