Q.
Hi, can you advise after my spring bulbs have flowered do I need to keep the leaves until they naturally die down or can I cut them back? Also do I have to lift the bulbs each year or can they remain in the ground and still flower next year? Thanks, Michelle.
A.
Once bulbs have flowered, leave them in the ground and allow the leaves to brown off as that is the bulbs food supply. If you cut the leaves off then flowering and bulb health will be affected for the following season.
Apply a side dressing of Tui Bulb Food now, and try to keep the soil watered until the leaves die down.
Generally bulbs can last for many years in the ground undisturbed, until they get crowded and need dividing. However it will depend upon what bulbs. Daffodils are fine left in the ground but frost tender bulbs may need lifting and storing over winter and replanting in late winter, early spring.

Do I keep the leaves on my spring bulbs to die down? Comments
I have been given some family heirloom tree onion bulbs but how to I grow them. I put a bulb in the soil last year but now there about 300 plants. Should I have lifted them ----the onions were growing on the outside of the plant but weren't very big at all. Am I supposed to cook them or what do I do with them please. ?

As experienced gardeners we have grown runner beans for many years. Over the past 10 years we seem to have had a problem which occurs after the first flowering and supply of beans.The vines gradually start dry die off meaning no following crops as there used to be in the past. Someone suggested a red spider mite maybe the problem.In any case is there a product we can use to deal with this? Many thanks. Elsa & Alan Collecutt

Often wondered if an answer like this fits all. Thanks, and for the question, Michelle!!

Hi Lynne, thank you for getting in touch. Tree onions are wonderful, use them like you would a spring onion or shallot. They are easy to divide and transplant. Plant them into soil that is loose and well dug over, full sun is best and keep the soil moist. A drench with Seasol plant tonic will help fire them into action. You can leave them in the soil and let them bulk up, they don’t have to be split up every year. Enjoy them! - Tui Team.

Hi Lyn, thanks for getting in touch. It sounds like your bulbs need some bulb food. Leaves and no flowers often signals the bulbs are lacking nutrients. Leave the foliage on the plants and sprinkle some bulb food around the base of the bulbs now, this will help the plant start to initiate flowers for next season. Transplanting them to another spot may help too, they are best where they can get full sun in winter. Thanks, Tui Team.

Hi Elsa, oh dear this isn’t good and it quite possibly could be red spider mite, or it could be a fungal problem. In either case, spray with a fungal spray and insecticide as soon as the first lot of flowers start to appear (check at your local garden centre), do this a couple of times and it should prevent the problem happening again. To give your plants a boost a monthly drench of Seasol will help toughen the plants up to an attack of anything. Your other option could be to move where you plant your crop; nasties can build up in the soil, so crop rotation is always a good process. Thanks, Tui Team.
