养花配土放什么药？小白药，小粉药都行，白药防虫，粉药杀菌。养花的土需要消毒吗？喜欢在家里养些花花草草的朋友们都知道，每年给花换盆换下来的土都有很多，却不知道如何处理。养花的旧土直接扔掉太过于浪费，换下来的花土直接在使用没有养分，而且土壤板结。

回收利用要慎重！养花旧土可以使用的情况如果是正常换盆剩下来的土，可以继续使用，大部分花卉，每1-2年就要换土一次。盆土中的养分逐渐消耗殆尽，最重要的是土壤中的颗粒粉碎，很大程度上影响了通气和排水性，造成新植株根系因为呼吸不畅或者无法延伸等问题。

所以，要对养花旧 土重新进行添加配 土才能 使用，需要补充新的 土壤 和 有机质。 nurture. If the soil is infected, it needs to be disinfected.

There are two common methods for disinfecting flower pot soil: solarization and chemical disinfection.

Solarization involves placing the soil in a plastic bag or container and leaving it in direct sunlight for several days. This method is effective because it kills pathogens by heating them up.

Chemical disinfection involves using chemicals such as chlorine bleach or formaldehyde to kill pathogens. However, this method can be dangerous if not done properly, so caution should be exercised when using it.

It's also important to note that some plants are more susceptible to disease than others, so it's best to research which plants are most resistant to disease before choosing them for your garden. Additionally, proper care and maintenance of your plants can help prevent disease from occurring in the first place.
