Don't over-fertilise tomatoes! Here's a good feeding schedule

by Allan

My tip for growing tomatoes is to use a good fertilisation plan.

First, use a good, balanced fertiliser during pre-planting, working it into the soil just as you would for planting potatoes.

Then, I don't apply any more fertiliser until tomatoes begin to ripen. At that point, I use a little 0-5-5 - no nitrogen - once only. This is where I believe it's easy to make a mistake. By fertilising too often, tomatoes get too much nitrogen, hence too much top leaf growth.

One more thing: gypsum is a great soil conditioner for tomatoes. It contains calcium and sulphur which keeps your growing medium from packing down.

Tomato Dirt footnote:
Great points from Allan! You may want to consider two of the most respected tomato fertilizers out there for your second application: Tomato-tone Organic Fertilizer and Miracle-Gro Tomato Plant Food .

mildew prevention
by: allan

hi, another thing i have found to eliminate mildew is puff spray your tomatoes and cucumbers with copper oxycloride weekly preferably morning if a sunny day is on the cards, under the leaves also.tomatoes are finished in new zealand, its been a good year in the tunnel house mainly due to this practice.

Thanks a lot for providing these feeding schedule. As according to the schedule I feel I was over feeding them with the fertilizers. That is why they show some stunted growth and bad tomatoes. Now it is time to replant everything.
