Your gardening questions answered

Hi everyone,

Thank you to all those who have left comments on my blog – it's great to hear your views and to get your gardening questions. I've picked out a few of your dilemmas, and I hope you'll find the answers useful…

Trailing begonias Feeling confused, purchased trailing begonias from your show on TV, you suggested putting three trailing begonias to a basket and displayed a picture of a wonderful basket of begonias.
Having read your advice you now say to over fill baskets with plants to get a good show, my baskets have been made up for three weeks now with three plants to a basket – is it too late to add more plants?
Iris Ashworth

Richard: There's no simple answer to this, as it really depends on the type of plants you're using. For a fabulous display of Apricot shade begonias (sold in the begonia collection), I'd plant sixteen of them in a 40cm (16") hanging basket. But if I was planting the giant flowered picottee trailing begonias, I'd plant far fewer, just five in a 30cm (12") basket or eight in a 40cm (16") basket.

When I'm planting mixed baskets containing lots of varieties of different plants, that's the time I cram in as many plants as I can. If you've planted lots in the same basket, it's especially important to feed them regularly to help them all flourish. I use Flower Power as my feed.

Read my hanging basket tips and best plants to use.

 

My garden is overrun with slugs. I am not a huge gardener but it is definitely ''growing'' on me. I bought some new plants and almost the next day they had been eaten – very upsetting. Please can you help with the best thing to get rid of the little slimers? Don't mind if it's organic or not – desperation is setting in!!
Sue Lipscombe

Richard: Deter slugs by sprinkling a circle of sharp grit around vulnerable plants. If the plants are in pots, another good method is to tie a couple of strands of copper wire (about 1cm apart) around the rim of the pot – the slugs won't crawl over the copper.

Beer traps also work well. Sink a clean, empty margarine tub into the ground, with just the rim above soil level (to stop any beetles from falling in). Pour some leftover beer (if you have any!) into the tub and the slugs will be attracted by the smell, then fall in and drown.

You could also try biological control, which you water onto the ground – it's very effective and safe, but a bit pricey. Or simply use slug pellets, but don't overdo them: sprinkle the individual pellets about 15cm (6") apart.

I love growing lilies but I always get this black bug on them which ends up killing them. Can you please tell me how I can treat this?
Jean Spencer
 
Richard: It sounds as though they've been attacked by the lily beetle. Most people notice them as red beetles sunbathing on the leaves and don't realise the damage they can cause. Left alone, the beetles can strip a lily of all its leaves in a matter of days. You've described the larval stage, a little grub that hides in a layer of unpleasant black grunge. To get rid of the pest, squash the beetle and larvae between some leaves. But if you don't like the idea of that, spray with bug killer.

If you've got a gardening problem, feel free to leave a comment below and I'll try and answer it.

Happy gardening,

Richard

    Hi Richard
    received my 14 giant begonias today and I am a little dissappointed in their size. Definitely not as shown as TSV. There is a note with the bulbs telling you they are not as advertised but will be O.K.
    As you always say the bigger the corm or bulb the better the flowers. The biggest ones are pink three and half inches, but the smallest is yellow and red barely two inches. Just thought you should know and would value your comments. The pink ones are the only true size that you displayed on T.V. I feel we have been let down.

    Hi Richard, Can you recomend a lovely golden Laburnum tree that would be good to plant in a container in my garden as a memorial to my dad? Also, if so , where would you suggest I source it from? Thanks Lorraine

    Hello Richard,
    I wonder if you can help. It appears that I have what is called Japanese Bind weed now growing in my garden beds and now into my lawn. I have tried all kind of weed killers but have not had any luck, the local council are not interested either. Do you have any miracle suggestions?

    Hi Richard
    On one of your previous gardening programs, you spoke about Prevado, or something simular for pests on Tree lillys, can this be used as a general insectecide say on tree peonies, apple, pear , or strawbery plants etc.

    Hello Richard
    Please can you help me.
    I have a poinsettia which was purchased at Christmas 2007.I have followed the instructions and it began to colour leaves at Christmas 2008. Subsequent instructions advised me to cut the plant back in late winter. It is now sprouting new leaves which are deep red.
    I am confused from the several advices I have received and would therefore welcome expert advice. Will I have red leaves this Christmas, Richard?
    ps I bought some begonias from QVC earlier this year and thery are still are at plug size. Can you offer advice, Richard?
    Many thanks

    Hi Richard,
    I have a beautiful Robinia tree which is about 25 years old. Unfortunately this year it seems to have quite a few dead branches and twigs and the leaves are very stunted in growth. To add to the problem, this morning I noticed wood pigeons eating what few leaves we have. Any advice on treating the tree and deterring the pigeons please?!
    Many thanks.

    Hi Richard, I am desperate to know what is the problem with my aloe vera plant. It is a very large and usually healthy plant in the conservatory. Recently it has started to have twisted bent stems which are turning orangey brown at the end -almost as if it hasn’t any pulp in – I have watered it sparingly, sprayed it with mist and fed it with succulent feed. I don’t want to loose it as it is such a feature. can you help?

    Thanks Jill

    Hi Richard,
    I’m based in Wiltshire and I’d like to grow several crops of early and main crop potatoes in succession as there’s only two of us and I don’t want a huge glut all at the same time. What’s the latest planting date for each type,how long can I keep the seed potatoes and where’s the best place to store my seed potatoes until I’m ready to use them ?
    Thanks, Liz

    I bought your Geranium ‘sky rocket’. Plants are healthy and growing well.The instructions don’t mention climbing geraniums so I don’t know whether to pinch them out or not. Your supplier won’t answer the question as they say you sold them to me.
    Trailing geraniums you pinch out, standard you don’t. Which instructions do I follow?

    Hi Richard – I bought the Lady Boothby fuchsias last year – putting 2 on a sheltered SW facing fence, 2 on a sheltered NW facing fence and 1 in a pot which I brought close to the house for the winter. Growth was slow but promising and I did have some flowers. Sadly none of them came through the winter. I was under the impression that they were hardy. Should I have prepared them for winter treating them as half-hardy? Very reluctant to buy replacements. Would welcome your comments.

    Hello Richard, Yesterday I received my japanese maple dual twisted tree. I have potted it up as per instructions. Should I remove the tape that binds them together at the top of the tree? I am concerned that this will restrict growth as the tree thickens out. I remember that you said to leave the tape at the bottom of the tree.
    i look forward to your reply.
