My camera allows me to look at the garden more intently. This way I am always reminded of all the creatures that make up the ecosystem that is our garden. And there is always a balance of good and bad. As in the Garden of Eden, there could not be the fruit without the snake.

With the good bees, there is also unfortunately the ‘evil’ of aphids and rose beetles. Aphids are among the most destructive insect pests in the garden. Feeding on the sap of young rose-buds and leaves, they affect the whole rose display negatively. We tend to spray a solution of dish-washing soap and water to try and reduce their numbers and not affect the ladybirds and birds feeding on them.
Damage caused by aphids is evident in decreased growth rates, mottled leaves, yellowing, stunted growth, curled leaves, browning, wilting, low yields and death. The removal of sap creates a lack of vigour in the plant, and aphid saliva is toxic to plants. Aphids frequently transmit disease-causing organisms like plant viruses to their hosts. I have decided that aphids are an ‘evil’ menace and I am very happy to see the ladybirds feasting on them.
The ladybirds are very welcome in our garden, feeding on aphids and scale insects. Seeing the little black spotted red, orange and yellow angels in the rose garden gives me hope in the fight against aphids and scale insects. The Afrikaans name for a ladybird describes it the best, ‘Lieweheersbesie’. Loosely translated back into English it is ‘sent from God’. That is so true.

When we harvest compost from the compost bins, we may encounter many of the large white grubs. I normally feed these to the Fiscal shrike who eagerly watches the cleaning of the compost bins from a good vantage point close-by.
On hot days we just pick the beetles off the roses by hand and kill them. Killing them is not easy because they are very tough.
Amazing close ups Thys!

DeleteExcellent post and wonderful pictures! So thrilled to see that you are encouraging your "beneficials" (the ladybug's and the fiscal shrike) to assist you in your "war of the roses". Couldn't resist that last comment! ;-) That said, a reminder to all like-minded gardeners. Don't panic at the first sight of aphids and start spraying away. If you want the ladybugs in your garden as aphid assassins and sentinels,you need first to have aphids to attract them...aphids are a food source for the "good insects" and their offspring. If there's no food supply, you won't have the beneficials. You will notice a spike in the numbers of the bad guys at first, but be patient and the calvary will come charging to the rescue and take down the villains and keep them at bay. As in all things in nature it's a balancing act. Again, great post!!! Susan
ReplyDeleteThank you Susan.
DeleteLove Susan's description 'war of the roses'. It aptly describes the situation so graphically captured in your superb images Thys.
