6. Padl\u00ed a dal\u0161\u00ed choroby<\/h2>\n\n\n\n

Pokud se na listech objevuj\u00ed nejen \u017elut\u00e9 skvrny, ale tak\u00e9 b\u00edl\u00fd mou\u010dnat\u00fd povlak<\/strong>, m\u016f\u017ee j\u00edt o padl\u00ed.<\/p>\n\n\n\n

Choroby se mohou \u0161\u00ed\u0159it rychleji p\u0159i nevhodn\u00fdch podm\u00ednk\u00e1ch, zejm\u00e9na pokud je porost p\u0159\u00edli\u0161 hust\u00fd a listy \u0161patn\u011b osychaj\u00ed.<\/p>\n\n\n\n

Napaden\u00e9 \u010d\u00e1sti rostliny pravideln\u011b kontrolujte a p\u0159i siln\u00e9m napaden\u00ed je odstra\u0148te. Z\u00e1rove\u0148 zajist\u011bte dostate\u010dn\u00e9 proud\u011bn\u00ed vzduchu kolem rostlin.<\/p>\n\n\n\n

7. \u0160k\u016fdci mohou tak\u00e9 zp\u016fsobit \u017eloutnut\u00ed<\/h2>\n\n\n\n

Listy cuket mohou po\u0161kodit tak\u00e9 \u0161k\u016fdci. M\u0161ice, svilu\u0161ky nebo dal\u0161\u00ed drobn\u00fd hmyz mohou s\u00e1t rostlinn\u00e9 \u0161\u0165\u00e1vy a zp\u016fsobovat skvrny, deformace nebo celkov\u00e9 oslaben\u00ed list\u016f.<\/p>\n\n\n\n

Pravideln\u011b proto kontrolujte spodn\u00ed stranu list\u016f, kde se \u0161k\u016fdci \u010dasto ukr\u00fdvaj\u00ed.<\/p>\n\n\n\n

P\u0159i zji\u0161t\u011bn\u00ed napaden\u00ed je vhodn\u00e9 nejprve ur\u010dit konkr\u00e9tn\u00ed druh \u0161k\u016fdce a n\u00e1sledn\u011b zvolit odpov\u00eddaj\u00edc\u00ed zp\u016fsob ochrany.<\/p>\n\n\n\n

8. Star\u00e9 listy p\u0159irozen\u011b \u017eloutnou<\/h2>\n\n\n\n

Ne ka\u017ed\u00e9 \u017eloutnut\u00ed znamen\u00e1 probl\u00e9m.<\/p>\n\n\n\n

Star\u0161\u00ed listy, kter\u00e9 jsou ve spodn\u00ed \u010d\u00e1sti rostliny a postupn\u011b \u017eloutnou, mohou jednodu\u0161e dokon\u010dovat sv\u016fj p\u0159irozen\u00fd \u017eivotn\u00ed cyklus. Pokud rostlina z\u00e1rove\u0148 vytv\u00e1\u0159\u00ed nov\u00e9 listy, kv\u011bty a plody a nevykazuje jin\u00e9 zn\u00e1mky probl\u00e9m\u016f, nemus\u00ed b\u00fdt d\u016fvod k obav\u00e1m.<\/p>\n\n\n\n

Ko\u0159eny:<\/strong> Nejsou rostliny dlouhodob\u011b vystaveny stojat\u00e9 vod\u011b?<\/p>\n\n\n\n

Teprve podle zji\u0161t\u011bn\u00e9 p\u0159\u00ed\u010diny upravte p\u00e9\u010di.<\/p>\n\n\n\n
