Advice of the month March
The summer is now established, with its long hot days and others stormy. Your main worry will be to preserve your garden if you go on holiday: a neighbour will be able to come to water the too dry days, unless you establish a system of watering integrated, properly tested and proved.
- Fruit trees
Prune apple trees, pear trees and other fruit trees with stone fruits.
Water the young fruit trees to assure their resumption.
Prune shrubs deflowers and cut the faded flowers (buddleia, kolkwitzia), this will favour the next blossoming.
Take a cutting from shrubs as from Common Smoke Tree, barberry, buddlejas, deutzias, elaeagnus, spindle trees, hydrangeas, seringa, spireas, privets, viburnums, weigelas.
Bring some fertilizer, peaty soil and water copiously to the plants which grow in peaty soils, when flowers fall (azaleas, rhododendrons, camellias) to favour the appearance of nice buds.
Layers rhododendrons and other plants of peaty soil.
Treat on hydrangeas in flowers by watering them and by cutting the faded flowers.
Watch the appearance of red spider mites (Tetranychus urticae) and Pine Processionary (Thaumetopoea pityocampa) on conifers that will turn yellow and fall off the needles. Spray the foliage thoroughly with clean water in preventing or treating with an insecticide containing deltamethrin. Do not touch Pine Processionaries that create itching. The remedy of a grandfather which consists in burning them is extremely dangerous in a neighbourhood of conifers dried out.
