Sandy Loam Very Hard on Top After Watering

[bkrauska]

I've just built 3 raised beds and had sandy loam delivered with which I've filled the beds. I then added compost on the top and mixed it about half way down into the soil. My problem comes after a rain or watering the plants/seeds. When it dries the soil creates a very hard top layer about 1/4-1/2" deep. I'm worried that the seeds that's i've sown are going to be able to break through it. I'd also like to avoid having the re-till or break up this hard layer any time I'd like to work with it. What do I need to add to the soil to prevent the hard layer on top forming? Let me know if you need any other information.

You need to water the entire bed thoroughly, and then apply a thick layer of mulch over the soil. Cover all the soil except where you planted your seeds. Seedlings are pretty tough, and can probably break through that crust, especially if you keep the surface moist ... unless you planted too deeply. You may need to lightly water the exposed soil more than once a day.

If you don't know what to use as a mulch, just type the word into the search box at the top of the page. You'll find a lot of discussions on the topic.

Thanks. I'll try that. I've been trying to water the beds real deep to keep things moist and I'll add the mulch.
