I have several arum lily Crowborough plants in different parts of my garden. Some are in partial shade some full sun. I do mulch them over the winter to protect the crowns. All the plants are healthy and have sent massive leaves this year however I have not had many flowers. Most of the plants have not sent any flowers up at all and even the most established plant has only sent one or two. I have fed all the plants with a general purpose fertilizer or tomato fertilizer and have watered well. Is there anything I can do to encourage more flowers next year. Anybody else had this problem?
It's been that sort of year Christine. Were your plants hit by frost and cold weather earlier this year? We had a long cold spring and everything was late. They normally flower in spring and early summer so by the time plants recovered they simply,wanted to grow, in my opinion.
I never feed mine. I think you are prob over tending them. I would stop feeding
Thanks for your reply. It was a long cold spring and the arums were possibly a bit later than normal this year so that could be the case. At least I did not lose them. I will try not feeding them next year to see if it makes any difference. I probably do over tend them as they are one of the plants in my garden which I would hate to lose. Did yours flower well this year?
No....nowhere near as good as usual. I put it down to unusual late spring. If we get a mild long autumn we may both see some late flowers! As I said, it's been that sort of year
Thanks for that. Very reassuring to know it is not just my plants which have not flowered as good as usual this year. I hope they do better next year. Always concerned I might lose them over winter being in the north of England so I do protect them using spent compost from the hanging baskets but will try not to give them as much "tending" next year.
I only got 2-3 flowers per plant this year. How damp is your soil? My Arum (I had forgotten they are called that and Zantedeschia aethiopica 'Crowborough' is a mouthfull!) are in heavy soil but free draining being near a west facing wall, so I am always needing to water them.
Most of my arums are planted close to walls but the soil is quite heavy and usually naturally very damp being in this part of Lancashire however I did water them a lot this year when the temperatures were very hot during July. I have one clump located next to my pond and two more in pots but they didn't flower although they are younger plants.
If you look it up at the RHS site, it classifies it as an aquatic or herbaceous perennial, so I would think it needs a lot of water - boggy conditions would seem ideal. Ground near walls tends to get quite dry so perhaps that isn't the best place for it?
You're right bob. They can grow in water. have done that myself, growing in a pond. They thrive in such comditions.....in summer. Remove from pool in winter. Cold and wet a big no for arums.
Thanks for all your replies and suggestions. Ironically the few flowers that did grow this summer were in a clump right next to the wall in full sun! The clump in damper ground nearer the pond has grown lush with numerous massive leaves but no flowers. Hoping for better luck next year. Doubtless they will flower if they want to!
Ironically, near the wall meant being warmer during the lomg cold winter and late,spring. Since then though it would have wanted moisture. ,good,moisture during the growing season but dry during the winter. Could you cover with a sheet of glass over,the winter Christine?
Covering them with glass is not possible but I could try fleece. When these plants were smaller I did overwinter some of them in pots in the greenhouse but sadly lost a lot of them, the ones outside did better. I successfully managed to grow some from seed though and these have done well. Just looking forward to more flowers hopefully next year.
Is there anybody who would sell Crowborough rhizomes?
I would like to buy more than a few...
