Hi,

I am trying to get advice on herbicides.

I am a landscape architect and have a 10m x 10m area of bare ground with lots of Wild Turnip (and Fumitory) seedlings appearing. There are obviously lots of seeds in the soil. Disturbance simply gets more to grow, as you no doubt know.

I am keen to kill the ones that are currently emerging and soon after spraying them adding about 25mm of seedling-friendly soil mix and then adding lots of perennial and annual garden seeds to this soil in an effort to out-pace the weed seed growth. Can’t think of a better way to do it. I do not want to buy the quantity of potted plants needed to shade out the ground. Too expensive in this case.

So, what I would like to know is who do I ask about which herbicides will do this job? I have looked online about Roundup and it is suggested that weed seedlings need to be 4 leaf stage or more for it to be effective. I’d like to hit all of the emergent weeds, including those just coming up out of the ground. The largest is only 10cm across.

Do you know about this sort of thing? Who else would I ask to get good advice?

Regards,

Peter

Hi there
Are you able to advise on what plants would go well in pots outside on a deck which gets very hot with miday sun till evening. I was wanting them quite tall/large but not sure what would survive in high amounts of sun.

Thank you
Charlotte

Please can you advise me what to do about a moth orchid that was flowering when I was given it, but hasn’t done since. I have had it for about 2 years and the leaves look healthy enough. I water it about every 2 weeks.

I have an espaliered apricot, I have been in the property for 12 months now and I suspect it is time for pruning but I can’t find any info specific to espaliered apricots. Is there anything specific I should know. It is now flowering and I live in Waimate ( South Canterbury).

Kind regards

I have cleared a large area on a bank that had had agapanthus and wild grasses on it. I have bought lupin seed, (as a mulch) hoping to increase the fertility of the soil. Is this a good idea? The lupin seed seems to say it is mainly for vegetable gardens.

I have been trying to grow courgettes but they seem to rot. I picked one of the rotting baby courgettes and noticed that they are being eaten by a small white bug that seems to be living in the soil. I have noticed these bugs before while watering, as they seem to come to the top of the soil while watering. It seems to be that the bugs are living in the soil and when the courgettes touch the soil they are being eaten and rot, can you help?
