救救我的朱顶红

<span class="bold"><br/></span><div style="FONT-SIZE: 12px;">我的朱顶红叶面发黄，大家看看</div><br/>&nbsp;[先是叶尖发黄，渐渐扩大。请问什么原因。怎么办[attach]30008[/attach]<br/>

是缺少光照么，或是水浇得太多了？

最好脱盆出来，看看根系长的如何？一般家庭养花最好偶尔要放到阳台上晒晒太阳，而且浇水最好一次浇透。

<p>虽然不是我的，但看到它的样子，我好心痛哦。</p>

发黄时从叶尖开始的貌似，我怀疑是烂根了，推荐先倒出来看看！

有可能是生了红蜘蛛。

<p>把球根挖出来看看是不是水大烂根了,要不暂时几天不要浇水看看</p>

<p>由老叶开始发黄看起来不像病虫害</p><p>看介质感觉是一般市购草花使用之介质保水性太好</p><p>光照不足看是不足 </p><p>以上参考看看 因为并没明白说明栽植环境及管理</p><p>所以仅能猜测提些意见 </p>
