How does spider mite attack actually kill a plant?

I was hoping that once I had killed the pests, that new leaves would start to grow, but the plant shows absolyutely no sign of life. Al The pests feed on the sap of the plant. If the infestation is really heavy, the part of the plant that they are on will dry out (just as if it had had no water) and die. Once the growing tip of a branch has dried out, then the branch itself may well die, and so on until the whole plant has died. The effect of the red spider is therefore much the same as not watering the plants for several weeks on end - if the "drought" isn't too sever, then you can water the plant and it will grow new leaves, like your second plant, but if the "drought" has gone on too long, the plant has died and nothing you do will revive it. It does take a pretty heavy rsm infestation to kill a plant. The good side is, now you know what they look like, you're in a better position to recognise an infestation early on. |
