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.
Be plantwise and don’t plant large Eucalyptus trees near buildings, carparks, playgrounds etc as they can do this as shown in pictures.
We have had some very damaging frosts around Melbourne this winter. Low-lying areas such as around creeks have been the worst affected. One of the areas I have seen the worst damage is Hurstbridge a suburb north east off Melbourne. There I have seen the surface of large water features holding two thousand litres freeze and the ground frozen like an ice-skating rink. Plants that normally tolerate the normal winter frosts we have had in past winters have been burnt this year such as mature Eucalypt trees. To try and help plants that have been burnt make it through winter there are a few things you can do. Firstly don’t prune plants, the dead foliage will help shield the undamaged foliage through winter and pruning encourages new growth which is more susceptible to frost damage. Don’t fertilize any damaged plants until frosts are finished for the season. Do give a treatment of seaweed solution once a fortnight through the rest of winter, this will give plants a better chance of survival. Cover plants with hessian if possible this may lessen the amount of frost damage, however the dew on the hessian may also cause it to freeze. Place plants under the canopy of other trees or house eves if possible. There are a few products on the market, such as envy, that claim to help protect plants from frost, always use as outlined in the directions. Hopefully some of these tips can help your plants make it through these damaging winter frosts we are experiencing.
