I have one plant, the really dark blue variety which has spread. Cover the roots lightly with soil, and water them. This will be extremely difficult for these pots. They should not be scared. There is some new grown showing on some leaves and others look just horrible. It does have two large double glazed windows and my plants are not in the dark! This encourages a deeper root … Knowing, to water a plant is a hugely significant and rare gardening skill. After one year a single clump would become three. They also like mulch around their shallow roots. I am very patient! Delayed Planting. I still have no idea why it wouldn't flower in the ground - it is in no less or more sun than before (both sunny positions), well-watered in both, but with less space in the pot which it was has been in for the last three years. Alternatively, cover the seeds with a … ps if you had an accident just leaving the evergreen type out in the cold it is only necessary to wait and keep your fingers crossed! Thanks,Holly, I would not be inclined to increase the proportion of nitrogen but would increase the amount together with other nutrients. However the instructions tell me to apply it to the soil and avoid wetting the leaves. Rhian, Dear RogerI made the mistake last winter of letting too much frost hit a wonderful large pot of these beauties and had assumed that all was lost - maybe all still is lost, I'm not sure. I wrap up the fruit tree pots with bubblewrap over winter - would that help agapanthus in pots to survive? For impressive displays use large pots, not fiddly small ones. Keep in mind that they prefer cramped root conditions so should be potted up gradually rather than swamped by huge amounts of wet soil in a large pot. Please bring succulent cuttings if you would like to share. I never feed any of my plants and the soils seem to be fine on their own. Both agapanthus and daylilies can become root-bound, even planted in the ground. Although I don't have any need to put any extra covering mulch in winter over mine in cold areas it might be a good idea. To produce the most flowers, the ideal is morning sun with light afternoon ... Propagation by Division. It is now about 4 feet x 2 feet and seems to have about 15 seperate "crowns" showing but has only produced 1 flower spike. Hi unknown - you can always add your name at the end of your commentIt sounds if your agapanthus might be the more tender evergreen type as you mention mushy leaves. I have grown them on both acid and alkaline soils with equal success Ray. I have just looked at my article and the one that is too dense is pictured. Many gardeners choose to provide these extra nutrients with a liquid feed. Maybe being a hybrid makes this one more pedantic about its conditions than my other (more common) agapanthus clumps which all flower without fail year after year? We were recently on holiday in Cornwall, and the Agapanthus is very widespread there, inspiring me to have a go at growing it. New leaves are good indicators of root growth. We all learnt a hard lesson in 2010 when a number of less-hardy plants in pots failed to survive in unheated greenhouses, yet in the open ground they came through. So what is rooting hormone? Eccentric or what? Sue. Is there any hope, or is it time to put the pot to better use?Thanks...Bill, I am not optimistic Bill. If you're looking for a great low maintenance plant for your driveway, fence line or even around the swimming pool, then you can't go past the agapanthus. Dear RogerI hope you can help me and my beloved agapanthus. I was so happy to run across your site I brought back White Agapanthus from Florida many moons ago and for long time they grew changed pots and they bloomed but this last fall I did not get them in and wanted to cry when I saw the leaves turn to watery mess.Was not going to give up threw all leaves away and brought them into TV room cleaned most of the papery stuff around each base watered lightly as bases were solid now they are growing back in the middle so hopes prevail, love that plant. I agree they respond to plenty of nutrients and tomato feed is the best balance for most ornamental plants. If you can, split each clump in half using your hands (a). Good for my ego. It still hasn't flowered… But all my other agapanthus plants have buds on them. Like Mark I've been inspired to grow them this year after seeing them on holiday - but not in Cornwall, in Provence where they really were the plant of the holiday. When thoroughly wet slice it into large pieces with a sharp spade. Avoid splitting plants too often as this will reduce flowering. Clumps growing in the ground can be divided in spring or autumn when they get too thick - every four to six years; this will improve flowering and is the best way of propagating them. Again very interesting post. This year they had it a bit difficult, because we do not heat our greenhouse anymore so last long winter they survived in the dark basement. Some people like to use honey instead. It is easy to grow and hardy, but this also makes it weedy in the wild. Take a close look at the roots at soil level. In dull wet weather it might be as little as once a week. Again, a very useful post. After separating the plants the wound should be sealed by coating in a dusting powder like Yates Tomato Dust as shown. From what you say, I think I should fertilize more. Perhaps they have bought small delicate plants grown soft in a tunnel or stood too long on a garden centre bench? Hi CliffordIf its any conciliation some of my own tub agapanthus are a bit sparse this year although all those in the ground are better than ever.In fact I have been getting grief from Brenda - particularly that same plant as in my photo that is still hardly flowering.I think some of my pots have too many crowns competing with each other but I think it is more down to poorer light this year and perhaps loss of nutrients by leaching last very wet Winter. Companion planting, is it just tosh or is there something in it.
