Is mahonia invasive?

There are several species of mahonia, Mahonia media and Mahonia japonica both form an upright shrub, and are the varieties most commonly used in gardens. Mahonia aquifolium is a shorter, spreading shrub which does send up shoots all around, and can be a bit more troublesome. Also called Oregon Grape.

Spot on!

Mahonia japonica is what most of us have - the US Mahonia (a decent evergreen shrub but Holly Osmanthus gives the same foliage effect with more elan) is a different species and is the invasive one.

Weeds covered all over my slate chippings

Membrane only stops/slows weeds coming up and not those that self-seed in between. Stones and slate provide heat and dampness that is ideal for seed growth. As you have lots of seedlings it sounds like self-seeders to me and membrane will do nowt for that. They prick out easily and do it now before they flower and send more seed out. A lot of seedling will come out just by raking over the slate.

it flowers like nothing else in winter. 

They have no scent for me apart from a faint honey smell.  Some people cannot smell Freesia (or so am told) for me it is Mahonia.

That is right Fairygirl, they go red and spindly with very few leaves in full sun. Mine in deep shade is deep green and glossy and looks like a different plant.

They can grow in pots Flora Rosa as long as you keep them watered.

I thought they only pupped when the roots are disturbed. So if you want it to spread, keep digging around their roots. My Mahonia Charity is in deep shade and looks great - in other gardens in full sun they look terrible.

No - they are temporary buildings thus do not need planning permission.

There is limited space in all shops, so selling cheaply is a good way of getting rid of unwanted stock. Shops know that bargain hunters tend to also buy full price plants at the same time and bargains keep em coming, so it is a win-win for them. End of season in Oct-Dec is a great time for bargains as is buying ahead. winter plants now, spring plants in dec etc.

Onion bulb gone soft

Posted: 06/06/2014 at 22:40

I planted some shed bought onion sets early this year. I had to shift most of them as I had planted them quickly. It has been on the dry side for me this year. I have noticed that almost all the onions have soft bulbs though all have good leaves.  Is this a result of root disturbance mixed with dry conditions or is this a disease? Space is essential this year so if they need to go then I will lift.

 

Many thanks

I bought 2 6ft Cordyline's with thick trunks for £7.50. One of them is in flower. Excellent buy and they delivered them for free!
