Problem with placing of my Reed-Blocks

[EisCube]

Hi there

I am currently working on my first mod.

My mod adds new types of Reed-Blocks.

I managed to get my reeds grow but I can place them anywhere!

I want them only to get placed on a special block with water around.

 

It would be nice if you explain the solution to me cause I'm new to java.

 

here are some examples from my code:

 

MyModMain:

	...

	public static Block myReed;
	public static Item myReedItem;


	@PreInit
	public void preInit(FMLPreInitializationEvent event) {

	}

	@Init
	public void init(FMLInitializationEvent event) {
		myReed = new BlockMyReed(500,32).setHardness(0.0F).setBlockName("Wooden Reed");
		GameRegistry.registerBlock(myReed);
		LanguageRegistry.addName(myReed, "Wood Reed");

		myReedItem = new ItemMyReed(600).setItemName("Wooden Reed");
		LanguageRegistry.addName(myReedItem, "Wood Reed");
		}

		...

	float var3 = 0.375F;
        this.setBlockBounds(0.5F - var3, 0.0F, 0.5F - var3, 0.5F + var3, 1.0F, 0.5F + var3);
        this.setTickRandomly(true);

Thanks for your help
