About The Long Island Gardener
Expertise
Do you know the wrong fertilizer will keep your plants from blooming? Do you know that too much Nitrogen can kill your grass, even if it does not burn the roots? Do you know that Roses need a LOT of Nitrogen to bloom -- and why is that? There's some complex chemistry in those plant foods. The secrets behind N-P-K are the key to the ultimate lawn, the the biggest flowers, the most fruits and vegetables. And if you don't get it right, you could be sorry. I'll show you what you did wrong, and how to fix it.

Experience
Homeowner with gardens indoors and outdoors, lawns back and forth. I wrote my first gardening column for our college newspaper, teaching roomates about the right way to feed those windowsills gardens. Today I look for challenges. Organic Fertilizers are the key to proper feeding of all our plants. Can you make your own fertilizer? Some people think so -- but there are side effects. I have been there, done that for 54 years and there is nothing like the voice of experience when it comes to Horticulture and Fertilizers.

Publications
Numerous and sundry but only in college did I write about plants.

Education/Credentials
B.A., Botany and Mass Communications.

Subject: Fertilizer for Kalanchoe and Rose

Question
Hi,

which NPK should we use for Kalanchoe and Rose ? I read one article told NPK 2:1:2 good for blooming Kalanchoe flowers, another article said NPK 1:3:1 is better. I'm confused now. Ditto for roses, which NPK good for blooming flowers ? Can I add CaO (from drying material like silica gel) and Mg(OH)2 (from medicine for stomachache) ? Thank's for your help.

Rgds,

Ari

Answer
These amendments are moot, my friend, because you do not know what you HAVE in your Soil.

You have one container of 2-1-2.  Another with 1-3-1.  You think you are putting it in current 0-0-0 Soil?  Think again.  There's microbes in that Soil  Are you dealing with Soil in the garden, or Soil in a pot?  Makes a big difference.  Who knows if you need ANY Mg or Ca at all?  There's only one way to find out.

Give me your zipcode, and I will give you all the information you need to TEST YOUR SOIL!
