Garden Diary: Container Gardening – Cochonilhas or Mealybugs?

On Monday, I met up with Joan a fellow “container” garden  enthusiast  and a regular visitor to my blog. It was great to not only see all her wonderful pots of fruit, vegetables and flowers, ask numerous questions ranging from types of compost, worm farms to problems with insects, but also discuss our successes and failures.  For example I discovered Joan’s zucchini suffered from the same problems as mine – once the flowers fall off the end of the baby zucchini wither and rot!

Joan is a mine of useful information and after my latest setback with tomatoes, I suddenly felt inspired and re motivated! We could have happily chatted for a week and still not have covered everything! (Mr. Piglet, my chauffeur was happy, when he discovered her husband was a fellow football enthusiast).

Another tidbit of information shared was the agricultural centre Sanipina where I could not only buy garden “potions” but also receive simple practical and knowledgeable advice in English!

For anyone living in the Algarve here are the details.

Sanipina

Algarve
Monday to Saturday – 8:30 to 19:00
T: (+351) 282 341 742 (+351) 282 341 742

Delighted with the above recommendation dear Mr. Piglet kindly agreed to make a detour (without moaning) on the way home via the agricultural centre AND a garden centre. Luckily, before leaving home that morning I’d collected various samples of the bugs which had taken up residence on my plants and fruit trees. It’s always easier to show rather than try and explain to the “experts”. So not only did I get the pesky bugs identified and prescribed a suitable potion, I also bought a black fig tree which resides in a huge pot.  Fingers crossed this one, unlike its predecessors would survive!

Do these bugs look familiar?

The assistant at Sanipina carefully inspected my bug specimens and pronounced they were all members of the cochonilha family because when you squished them they released a reddish liquid. I also learned this is where the colouring Cochineal originates from – I won’t be buying that again! I asked her if they were Mealybugs but she was not familiar with the name. I checked them both out on Wiki and they look the same to me, so I assume they are? Can any of my Portuguese followers help with this one, please?

Products recommended for Cochonilha

Products recommended for Cochonilha

She recommended using a combination of two products for maximum effect. However, the advice came with lots of “ifs” and “buts” instructions.
* Water well before spraying
* Do not use in direct sunlight
Fruit trees
If trees are in flower or have fruit which are less than the size of a walnut do not use the Pomorol (see product in large pot).
Bay Leaf Laurel
Use combination of both products, but do not eat the leaves for at least a month.

Ants
The insecticide in the small pot also kills ants!

I hesitate to use chemicals, but as the infestation is so bad, and now spreading to other plants, I need to take drastic action. A couple of the badly infested plants in small containers I’ve now quarintined and applied the insecticides and will also disinfect the pots for good measure. Time will tell…

Joan also suggested lots of natural remedies such as garlic, chilli, tobacco, rhubarb leaves etc plus Insecticidal Soap. I’m going to try these on some of my other plants to see how effective they are and will make another post later in the year with the results. In the meantime, if you have any suggestions or useful links, please leave in the comments below and I will add to the “useful links” below.

  3. I have the same problem with my lemon and bay tree, the local garden centre gave me a recipe to mix up and use but I have not got to it yet. Will report back and share it if it works.

  4. Hi Carole: your laurel sees to have mealybug; the citrus seems infected with scale. I’ve had both my lemon tree and fig tree infected with those last year. Because I prefer not to use chemicals I was given this recipe and it worked after 3 sprays. I think with the scale the ants are to blame, I was told!

    You can treat both ecologically with a spray made out of 1 cup alcohol, 2 tablespoons dishwashing liquid, 2 tablespoons cooking oil, 3,5 litres water. Spray all over; both sides of leaves; and repeat 2 or 3 days later.

    Best of luck, these pests are a pain xx

  5. Well horse-potatoes!!! I had a nice long boring comment ready to post and it disappeared. ๐Ÿ˜ฆ
    So, I’ll give you the short version of what the infestations remind me of:
    Wooly Aphids
    Hollyhock Rust
    I don’t know if either one of these are in your region, but I thought I’d mention them anyway.

    I’m glad you & your friend and Mr. P had a good day out. It sound like a fun and educational experience. ๐Ÿ™‚

    • Hi Cocomino, what type of things do you grow? I have some Aloe Vera plants which are very good when the sap is applied to sunburn etc I don’t make any of the drinks for digestion though as I’m a little wary.

  12. Hello PiP, I have have been surfing the net to find out more about these pesky creatures. There seems to be a quite a variety of mealy bugs. looks like the ones you have found are the monsters. There are even mealy bugs specific to citrus trees. The ones I have come across have been eradicated with white spirit or methylated spirit but those cochonilhas in your garden are more difficult. I have read that products containing fatty acids (whatever they are) are needed for the more challenging bugs.
    The best of luck. I am sure you will overcome this latest test to your green fingers.

    • thanks MC, I ‘ve certainly found an interesting selection of bugs! I have used a concotion of sunflower oil and blue soap in the past but I never got the proportions right as I nearly killed the plant because I smothered it! Killed the bugs though ๐Ÿ™‚

  13. Hi PiP,
    Sorry I haven’t been by lately…but you and your veggies have been in my thoughts. ๐Ÿ™‚
    Best of luck…hope the solutions are a solution to the problems! I remember one year when our blueberry bushes (100 of them) had an infestation of some beetle…I paid my 3 children and the 3 neighbor kids a penny a bug…and gave each a cup half-filled with soapy water…and set them loose in the garden. What fun they had knocking the bugs off the leaves into a watery grave…then I went around, spraying the leaves with a soap solution.
    I look foward to hearing more about how your garden is growing. ๐Ÿ™‚
