Why Are My Seedlings Leggy?

What Causes Leggy Seedlings And How To Prevent It

Leaky soil causes legginess in your plants. If your seeds have been sitting around too long, they may not germinate properly due to the lack of moisture or even no air at all!

The first thing you need to do is take a look inside your garden and see if there are any leaks. You’ll probably notice that some areas seem dry while others are full of water. Sometimes it’s hard to tell which ones are leaking because they’re so wet from rain or other liquid sources.

If you don’t see any leaks, then chances are your soil is fine and you just need to provide extra watering when needed. But if there are leaks everywhere, then something else needs to change in your garden!

Now let’s start with what causes legginess:

1) Too much fertilizer – Some types of fertilizers like composted manure cause the soil to become overly fertile.

That means that it will produce lots of small roots, but little or no leaves. When these root systems die off, the plant dies. Soil testing can determine whether or not you’ve got too much fertilizer in your soil. (

See our article on How Much Fertilizer Should I Use?

to learn more about soil testing).

2) The wrong kind of fertilizer – Some types of fertilizer contain too much nitrogen.

This causes the plant to produce lots and lots of leaves, but not enough roots. The plant will eventually topple over because it can’t get enough food and water from the roots. Certain types of soil also don’t take certain types of fertilizer very well. Soil testing is a good way to determine which type of fertilizer is best for your soil.
