What is causing the petals to fall off my Dahlias!!

Posted: 12/07/2015 at 11:17

Dahlia flowers don't last long which is why they aren't usually available as cut flowers in florists.  Make sure you cut the seed head off soon after the petals drop to encourage more flowers.

The correct answer is to eat what is in season and not expect to have (say) french beans on your plate all the year round.  Most home grown produce can be frozen and although this takes electricity, it is far more efficient than flying in french beans from Kenya.

A flowering yukka??

They do take a few years before they start flowering but will then produce flowers in most subsequent years.  Occasionally they may not produce any which will be down to the weather.

I agree with scroggin and will add that they are probably the hardest 'ordinary' veg to grow well for gardeners.  Planting them deep (right up to the lowest leaves) and firming the soil well around the roots when planting helps.  I think they prefer heavy soils, so clay would be best and light sandy soils are probably going to lead to disappointment.

Interestingly, research has now shown that genetic variation can occur within a single tree:

Tulips in a Mixed Border

To give them the best chance of coming back, plant them deep (8" = 20cm) if you leave them in the ground.

Mine are all now in 50cm pots scroggin and they do well.  I re-pot in spring as that is when the roots start growing.  Over the years I have lost a couple when the roots rotted due to poor drainage and I think I may have potted those on in autumn so they could have been sitting in soggy compost over winter.

tiny black flying bugs

Probably two different insects.  The ones on your courgette flowers are almost certainly pollen beetles.  Those eat pollen but cause no real damage.  The ones making sitting outside unpleasant are probably thrips aka 'thunderbugs' or 'thunderflies'.

It's always very risky with such an established tree.  If you attempt it, you need to take as large a rootball as possible.  There's some good advice regarding that on this site:

If you do move it, avoid planting it anywhere where it will get early morning sun as that will damage fresh new growth in early spring, so an east-facing border is not recommended.  Also avoid anywhere open or windy - they need a sheltered site with some shade.
