After wind, plants need some love

After all the wind the island has experienced during the past ten days, I noticed many of our plants and trees had leaves that looked dead around the edges. Although we’ve enjoyed some refreshing rain, large shrubs and trees become dehydrated far quicker by wind than by drought, and unhappy leaves are a sure sign they’ve been affected.Image

So, in spite of the rain, most of my garden (apart from the vines) has been treated to a little extra water plus a good dose of copper spray on their leaves (including the vines).

Copper spray acts as a general fungicide so plants that are susceptible to black spot or mildew will benefit from regular use. Citrus trees and avocados, in particular, seem to become glossier almost over-night following treatment. When you visit your local garden centre you may see tell-tale bluish-brown dollops on plant leaves. This reveals that they’ve been given their strengthening medicine recently.

If there are late heavy rains, after vines and trees have already produced dense leaves,  the risk of mildew is increased. This problem ruined all our grapes a couple of years ago. After this experience we discovered that a thorough copper spraying could have saved both leaves and fruit before the problem became acute. It’s also useful on pear and apple trees if you see any evidence of fire blight disease. This is when the tips of leaves and shoots blacken and droop into crook shapes. Remove and burn any black parts and then spray the whole tree with copper spray, reapplying in a fortnight if the tree is still looking poorly.

Although copper spray is certified for use by organic gardeners, if you wish to go even further down the green road some gardeners claim that liquid seaweed achieves much the same results. This is said to work by boosting beneficial fungi which then counteract any bad ones.
