Re­gional rose tasks for Jan­uary

Home (South Africa) - - GARDEN DIARY -

Sum­mer rain­fall Re­duce the height of roses that have grown too tall, or thin out dense bushes, but only if the roses can be reg­u­larly wa­tered. It is best to cut back grad­u­ally, over two to three weeks. Do not cut back de­fo­li­ated roses but wait un­til they have re­cov­ered. Fer­tilise with Vig­orosa in mid-Jan­uary and spray ev­ery two weeks with Lud­wig’s In­sect Spray mixed with Chronos or use Rose Pro­tec­tor to con­trol fun­gal dis­eases and pests. Wa­ter deeply two to three times a week (us­ing grey wa­ter) in the ab­sence of rain­fall.

Win­ter rain­fall Sum­mer prun­ing can be car­ried out on roses that are well cov­ered in leaves and if there is wa­ter avail­able for ir­ri­ga­tion. Over a space of two to three weeks, re­duce the height of overly tall roses or thin out dense bushes to al­low new stems to grow. Wa­ter two to three times a week, fer­tilise with Vig­orosa, and spray with Lud­wig’s In­sect Spray to con­trol pests.

Lowveld and KwaZulu-Natal coast The chal­lenge of the in­tense heat is to keep roses cov­ered with cool­ing leaves that also shade the roots. Wa­ter deeply two to three times a week and mulch to keep the soil sur­face cool. Don’t re­move dead blooms or trim the roses, as this will en­cour­age sprout­ing. Spray with Lud­wig’s In­sect Spray to con­trol pests; drench the un­der­side of leaves to pre­vent red spider. Should there be good rain­fall, boost growth with Vig­orosa and spray with Chronos.
