Roselilies need an acidic soil, but you say plant them in a multi-purpose compost if planting in pots. Please can you clarify this for me?
Yes Roselilies do prefer an acidic soil if planting in the garden. However, for planting your lily bulbs in pots we do recommend a Multi-purpose Compost mixed with John Innes No.3 but if you have an ericaceous compost then that’s fine too!
We advise using this mix of Multi-purpose compost and John Innes No.3 for planting your lilies in pots as the Multi-purpose compost contains natural plant feed and nutrients to encourage strong growth of your lilies and it is weed free. The John Innes No.3 is ideal for your lily bulbs as it is loamy and free-draining but heavy enough to give pots stability. If you are planting with an ericaceous compost, then just ensure you have plenty of drainage for your lily bulbs. Hope this helps.
Could you please tell me what is the diference between soils? It gets confusing. I have been having success growing my lillies in John innes 1- 2- 3
and also Miracle grow compost, which seems to give me better results. I have been growing in containers, but I am planning to remove and plant in the ground,
Will this be better for the lilies?
If you are planting them in the garden you must have well-drained soil. I would need to know which varieties of lilies you have to advise which soil is best. Orientals need an Acidic soil. Asiatics lilies require an Alkaline Soil. Really, if you have a well-drained soil, replant them in the garden and see how they grow, you can always put them back in pots if they don’t do so well. I hope this help.
My garden is an alkali clay, so I grow my lilies in a 10ft by 3ft raised bed. L. Lechtlinii and Orange Tiger thrive, but Asiatic lilies do not. What soil proportions do you recommend for your Asiatic lilies?
Thank you for your question. The ideal pH level for all lilies is 5.5 to 6.5. Mix in some John Innes No.3 with your soil and this should help with your Asiatic Lilies.
