Is there a cure?
About a year ago I noticed my Aloe Arborescens were covered in dappled black marks, and after a few months the leaves turned black, shriveled and died.
Aloe Arborescens – black marks on leaves
There is an old adage: Don’t put off till tomorrow what you should do today.
Unfortunately, I never acted immediately and when I did seek advice I was told it was a virus and there was basically nothing I could do to cure it. I was then advised to remove all the affected leaves so only the new growth remained. I tried, but after spending many back-breaking hours pulling off the dead leaves I decided the plant was too far gone and we cut it back to ground level.
Apparently Aloe’s are rarely affected by pests although the root and dry rot can be a problem. I was about to give up on my mission to discover the cause of the black marks when someone suggested it could be a fungus due to humidity. Ah ha! After an extensive search of the web looking for clues I discovered:
Insects such as aphids and snout beetles sometimes attack aloes, and they occasionally fall prey to fungal diseases, such as rust, especially if they are growing close together. Spray the plants with a systemic insecticide to stop the sucking insects in their tracks.
Make sure that the poison runs into the growth points between the leaves as well. A fungicide with a copper base can help to control diseases such as rust, which are a nuisance in humid climates.

I am on a mission to find a fungicide with a copper base to save my one remaining Aloe Arborescen growing in another part of the garden. Can anyone recommend a product which I can buy here in Portugal or from the net?

All the plants pictured above have since been cut down to ground level in the hope they will regrow and I will get a second chance.
Does anyone have any other suggestions or advice, please?

In the UK gardening in January like the weather, was depressing.. However, here in the Algarve I’m amazed there are so many plants, shrubs and succulents in bloom.
One of my favourite flowers is the Arum Lily. The leaves die down in summer when the sun is intense but in the winter we are rewarded with the most wonderful flowers!

This post was originally reblogged from Piglet’s Plot in Portugal but due to a technical hitch I had to delete the post and start again. Does anyone else have problems reblogging or is it just me?
On the 15th of each month I participate in a gardening blog hop called Garden Bloggers Bloom Day where garden bloggers all over the world share what is currently blooming in their garden.
So what’s blooming in Piglet’s plot?
The temperatures here in the Western Algarve have not dipped below 3C at night and have hovered well over 12C during the day. In fact last night it was 18C. We’ve had lots of rain as well as sunshine so the perfect combination for hungry mosquitos as well as a variety of plants.

One of my passions is gardening and the Gazanias reward me with an ongoing display of unusual daisy-like flowers twelve months of the year.
These photos were taken today after weeks of showers, gales and heavy rain. I was amazed any had actually survived such an onslaught, so with a break in the weather I was pleased I was able to take some photos to share.
Gazania are one of my favourite perennial flowers. They provide a wonderful array of year round colour from cream through to yellows, oranges pinks and dark reds. I have tried to paint these flowers but my artists skills can’t quite capture their beauty and “do them justice”
Some gardening websites say they only bloom from late spring to early summer – these pictures prove them wrong. They grow well in sandy soil, prefer full sun but will grow in partial shade and only require watering once a week in the summer.
Gazania self-seed so the six plants I originally planted have now multiplied into to hundreds over several years. It is a good idea to dead head regularly as the flowers fade and turn to seed heads as the seeds disperse and grow anywhere and everywhere!
A little note: the original spelling as given by my local garden centre was incorrect. Thanks to hortophile in Canada I have now amended from Gazinas to Gazanias.
