Why is plant my dying?

Even if your plants are correctly watered and fed occasionally they sometimes die.  We can help you work out what has happened so you don’t keep spending money on plants only to be disappointed and out of pocket. You need to work out what has happened as it may affect other plants, then you can treat them before it’s too late.  Check the steams for pest or disease.  Have a close look at the foliage, is there any damage, have they been eaten, are there any bugs on them?  Take a close look at plants at night, lots of bugs only come out in the dark and also after rain.  Also check the roots, are they shrivelled from drought or water logging, have they been eaten by bugs?  Is the plant in the wrong position, too much sun or not enough, too dry or too wet, is the soil too acidic or too alkaline or is the soil texture to hard with too much clay.  We come to your garden and help you solve these problems with our garden consultation service.

Pimples on Lilly pilly leaves

If you have what looks like pimples on your Lilly pilliys leaves it’s psylids. Psyllids are tiny sap sucking insects and juvenile (nymphal) and adult stages do the damage by sucking sap from the leaves. There are many psyllids, all of which are relatively host specific, found on Acacias, Eucalyptus and Syzigium. psyllids have a protective waxy cover and can only be seen with a microscope.
Psylids can be controlled by spraying the tree in late spring with Confidor.

Black spot on Roses

Black spot is a fungal disease that effects roses. Older leaves will get what looks like black spots that get bigger then the leaf yellows and falls off. Black spot may spread until all the leaves fall off unless it is treated. Black spot likes warm humid environments. It spreads by contact, wind, water and aphids. You can help by reducing humidity, of course we can’t control the weather but you can water the soil below your rose instead of the foliage and avoid water splash from the soil onto the leaves. Humidity can also be reduced by increasing airflow, do this by pruning so that branches are well spaced and foliage isn’t too fence. Roses should also be in a full sun position with at least 6 hours of sun a day. There are also products avaliable that are copper based such as Yates liquid copper or you can use Eco – fungicide or Yates rose shield. Prevention is always the best cure and you can do this by making sure your rose is feed and watered well in a position that has well draining soil and lots of sunshine.

Leaf curl

*Curly pimpley leaves on your peach or nectarine? This is leaf curl and unfortunately once the buds have burst and the leaves have appeared it’s too late to treat this problem. It is a virus that entered your plant just when the buds burst and you started to see your plants new Spring leaves. In winter in June, you need to spray the plant with lime sulfur to protect the plant from the virus. Unfortunately  once the curly leaves are out all you can do is wait till next winter when the plant has no leaves and spray at bud swell, (don’t do it when there are leaves, it won’t do your plant any good it will damage it).

Deformed foliage on Roses

Have you noticed leaves on your rose that look curly, twisted, small, yellow with the veins that are green but surrounded by a yellow looking leaf? This is more than likely glyphosate damage. Roses are very sensitive to glyphosate which is found in some herbicides so be careful not to spray where drift can land on you roses.
Here is a photo of healthy foliage and glyphosate damaged foliage on the same plant. Notice the healthy foliage is different and much reder.

English box going orange

During winter many people find their English box going an orange bronze color. This is because Box likes a drier winter and a pH between 6.5 and 7.5. The combination of a low pH and waterlogging makes it difficult for the plant to take up the nutrients it needs to stay green. This is very common in clay soils where water isn’t able to drain away efficiently and the pH is naturally low. Two ways you can solve this problem is to improve the drainage and raise the pH. Adding gypsum and organic matter can improve the drainage and don’t overwater in winter. To test the soils pH you can purchase a pH testing kit from most garden supplies, and add lime to the soil to raise the soils pH as needed. Gypsum only works on sodic soils (dispersive clay). To test if your clay is sodic place a dry ball of your clay in a glass of water, if the water goes cloudy gypsum will work, if it is clear it won’t. Add compost to non-sodic soils to improve drainage.
