IslandB...welcome to the Washingtonia competition to see who can get the first fan leaf! Haven't starte to give mine any extra fed yet, so will be interested to read replies.

Islandbreeze - When did yours germinate? A few of mine are working on their 3rd strap leaf and I'm going to start watering them with (Green Light Root Stimulator & Starter Solution)(5-15-5) mixed with water.

You can fertilize palms when they are actively growing.
Seedlings should be fertilized with water soluble fertilizers mixed at half strength.

Greenclaws- thanks for the warm welcome, however, I don't think I stand a chance in this competition, as I believe you guys are growing Robustas, and mine is a filifera, which is supposed to be the slower growing of the 2 types.

Jay- I believe it was germinated around Thanksgiving? give or take a couple weeks, don't remember exactly.

Bmwsav- thanks for the info. That answers my question. I will use MiracleGro at half strength like you suggested, seeing as mine are actively growing. These are inside my house, so any idea how often they should be fertilized?

You never know what will happen with these things. I think they grow generally about the same rate at this stage. Greenclaw's robustas were peaking above the surface 3 weeks before mine but then mine took off and are about a leaf ahead of his now. These are so many variables so we should look at them on a case to case bases. You are so very in the competition. LOL! Just kidding there's no race.

You can fertilize with Miracle Gro in small amounts about every week to week and a half until they go outside.

Im using the root stimulator starter solution (5-15-5) for now. When they go outside I'll give them some "Milorganite" and Miracle Gro Shake and Feed Palm Fertilizer. We'll see what happens and I'll keep everyone posted.
