I'm sure your local feed store will know what lucerne hay is, but if it's not available i reckon the alfalpha will do it. Maybe Weezie or someone can help there. I'll look into it further.
The
tree will be right,as long as you don't bury the trunk at all. it'll get collar rot if you do. If you wanna incoorporate an existing
tree into a garden then leave a ring of space around it to avoid this. The earth won't get that hot, it'll just warm up a bit. Bear in mind that a
tree will use the new food source too so best not put the vege patch too near it if possible. Not a big problem though as the
tree roots if already under the soil layer will not tend to grow up into the bed but rather stay below and use leached nutrient. Of course it may depend on what type of
tree.
There's no such thing as goofy questions. Only goofy mistakes.
I won't be on for a few days so i haven't abandoned you. Travelling home from Africa and when i get there my computer is in the shop.. Oh yes.
