Avocado Plant

I have a year-old Avocado plant which I occasionally put out into the garden when it's sunny to give it a boost. I did this about a week ago where iI put it on a sunny ledge near some Roses against a fence...and a few days later I noticed Aphids on it. I picked them off and sprayed with soapy water, but now the younger leaves, one by one going down the plant, are shrivelling and going brown. I nipped off the stem to the next node for each leaf I removed - had to remove three, what's caused this?

 

O dear, the aphids may have given the plant a virus. I think you're doing the right thing by removing the affected leaves, i'd give it a feed too, to help it fight it off.

 

(Makes mental note to leave answers to someone that has more experience of avocados than hoiking them out of the compost in future:DOH

Did I say that outloud:DOH:

Wise words there Marley, didn't think of weather damage:o

 

I'm agreeing with Marley.

You cant just put what is basically a house plant outside for the odd sunny day.

If you acclimatise the plant it could probably spend the summer out doors in a sunny spot, but a plant that is used to growing in a protected, perhaps shady enviroment, would not like suddenly being put outside in direct sun.

 

:/ I've done it six or seven times and if anything it seemed to enjoy the boost, just this one time it's gone a bit funny, perhaps the Aphids pushed it too far as well..? So what do I do? Another leaf is starting to go brown. Cut back any more of the stalk and there won't be anything left...
