Lemongrass & snails on citrus tree
Hello, I just bought a house and there are various plants.
1) There is a lemongrass bush. I love this because we use it alot in cooking but my question is:
A) how do you harvest the stalks so that they continue to produce new stalks?
B) Should I be trimming it back, see picture attached, it looks out of control. I just dont want to do anything to harm it so that it continues to produce.
2) There is a kalamansi tree with some funky looking discolored leaves. At first it looked like some kind of oil or chemical had been dumped on it, but after weeding and cleaning the bedding I discovered a massive amount of snails at the bottom of the trunk and small and large snails sucked onto the leaves. I've deduced that this is why the discoloring. Questions:
A) How do I get rid of those in a natural way, if in fact, you agree that those are causing the problem?
B) Should I trim off those dead looking leaves (new leaves are growing around them) I've attached a pict of the discolored leaves.
Get a big bag of food-grade diatomaceous earth and lay a thick layer around the bottom of the tree. Reapply as necessary to keep a thick dry layer around the tree. the DE is microscopically sharp-edged and will desiccate the snails and slugs. i'm assuming they have to climb down and go to ground eventually.
snails - if you are in CA the large garden snails were brought by Basque shepherds and later went wild, if you want, gather them, keep them in a well-shaded screened cage or if indoors a well vented covered washtub. feed them on lettuce, greens, garlic, fennel (grows wild along the arid coast), rosemary etc. for a couple of weeks (cleans out their systems and flavors them a bit) and do like the Basques, fire up the BBQ, put a fine mesh grill on top, place them open side-up and slather in olive oil (but an adjustable fish grill-basket might work better to keep them in position).
I suppose you could broil them indoors in muffin tins in this manner. either way you'd want tiny little forks even after they release from the shell.
I've grown that lemongrass before. I don't believe what you've pictured is the type that produces the lemongrass stalks, but you can use the leaves for tea. Beware this plant. Do not let it go to seed. As soon as you see flower heads cut the plant back else you will soon be growing little else.
Here's a link that shows the difference between two types:
Can't offer any help on the citrus tree problem, sorry!
