Proper aerating technique?

16 years ago

I live at the beach and have fairly sandy soil so I have no experience at areating. I need some advice.

There is a section of my Bermuda yard that is on a slope. No matter how much I water that spot it is browner than the rest of my yard which looks great right now. The sprinkler is at the top of the hill and aims downhill. I try to add additional water with a hose end sprinkler by watering from the bottom up. It helps some, but not like it should.

I think the soil in that area is compacted as I am starting to see some Goose Grass pop up. Lots of websites say Goose Grass likes compacted soil and I don't have it anywhere else in my yard.

I am borrowing a core aerator from a friend and will give it a try. Could aerating also help with the browning grass? Should I mow first, afterwards to dispurse the plugs, or let the plugs lie and get dispursed by irrigation? I also plan to do my monthly fertilization after aerating. That's good right?

You can try aerating, but if you have sandy soil, compaction is unlikely the problem. Any slopes, but especially sandy slopes, are hard to water. The water just rolls on down and quickly drains away. If you are aerating anyway, I would suggest you topdress the area with some compost. It will fall into the holes and do a better job of absorbing and holding water than the native sand.

I second the compost suggestion. Another thing you might try is soaker hoses. You can water slower and deeper with those.

My guess is that aerating is not really your problem and so isn't going to help even if done right. Slope and fast draining are combining to just keep it drier than your other grass that you are happy with.

Yes, particularly for tiny seeds, you don't want to pour water over them. Either spray gently with a fine mist, or bottom-water (allow the water to be pulled up from a reservoir at the bottom). For now though, you'll probably have to wait and see what happens with your future seedlings.

FWIW - the newspaper will just slow drainage and retain more water. The stones won't improve drainage ..... in fact, they are counter-productive because they will cause water to perch in the soil ABOVE your drainage layer; and the bubble wrap won't offer any protection against killing lows - it will just marginally increase the length of time it takes for the temperature to reach that critical temp. CT - there are different ways to look at a soil. To me, a heavy soil is one that retains a lot of excess (perched) water. Light soils aren't necessarily light in weight, but they are airy and hold little or no excess (perched) water. Mature compost, or any kind of compost is great in the gardens & beds, but can quickly become problematic in containers because of its small particle size and its propensity to hold LOTs of water ...... something you'd be better to avoid in containers. If you concentrate on ensuring your chosen soil will retain adequate amounts of air (even at container capacity) for the expected interval between repots (different than just potting up) you'll be offering your plants a better opportunity to grow closer to their genetic potential. The fertilizer part is easy. If your soil has dolomite in it (which has the Ca/Mg Miracle-Gro lacks), you can use their all purpose 24-8-16 or 12-4-8. Don't concern yourself about building a soil to feed the plant. That's what fertilizers are for - container gardening is much different than growing in the earth, and many of the strategies (like feed the soil and not the plant) are best left in the garden. Al

"Proper" pruning techniques for fruit trees: Opinions?

There are some general rules. Branches should not shade other branches- whether open center or central leader. This means that each tier of a central leader needs to be a good distance from preceding one- usually 3-4' with free standing trees and each tier should be about half the length of the preceding one. Species or varieties of species that do not volunteer much secondary branching off scaffolds need to be cut back much more than those that do. J. plums scaffolds are often slow to fill out. I'm actually not sure what is the best method to deal with this because I've always cut back to a smaller branch when such trees extend long wood out with no branches coming off it. It eventually leads to filling out but I wonder if stubbing back repeatedly during the growing season might get you there sooner. Very vigorous growers can be managed most easily by removing all scaffold branches more than a third the diameter of the trunk at the point branch is attached to trunk. If this is done early, fruiting is quicker and a much more compact tree can be fruitfully maintained. For apples, I'm talking about the likes of Fuji, N. Spy, Mutsu, Macoun, Baldwin etc. Cherries are vigorous growers and this applies to them as well. They are also reluctant to provide secondary branching and cutting back branches during summer can be helpful for this. Many apple varieties bare their best fruit on second year wood, some on the tips of one year wood and some others on spurs up to about 6 years old- the books usually suggest it's all about long lived spurs with apples but this is misleading - no, it's flat out mistaken. The least structural wood to support the most smaller fruitful wood is always the goal. This means that 3 scaffold branches for an open center tree is best if the variety generates ample secondary wood. Same for first tier of a central leader. Further economy of wood is accomplished if you remove secondary wood more than half the diam. of the scaffold when things start to get crowded. Wood also is more efficient as it approaches horizontal as far as harvesting light, vertical branches use more wood to harvest the same light. That's all I have for the moment, but I can also provide more organized observations if you e-mail me for articles I've written, but I haven't gotten around to putting something together that goes from species to species. My articles are somewhat applecentric but much applies to all species.

Evenin' Squirt & Co., The danger is in the "assuming"! * Primer is cheaper than paint. THAT'S why (tinted) priming is SO important with the dark tones. * There's "horror" stories all over in painting-forums about people needing 4,5,etc. coats of "Red" to cover a white/light-colored wall!! Unless you like applying/paying for red...use a tinted primer!!! * Depending on your Red's formula, I can't rule out a 3rd coat of Red, even on a gray primer...it's rare, but don't rule it out! * Similarly...YELLOWS/GOLDS can be very "thin" too!! Depending on which tint-base these go into, & what colorants are used, Yellows can be transparent! D-wall's post has the right "recipe"! >>> ONE tinted prime-coat + TWO paintcoats for the 3 total coats. >>> Worst-case scenario is a 3rd paintcoat. >>> You'll get a better look from the job if they prime + 2 paintcoats. >>> Again...primer is cheaper than paint!!

I'm going to give it a shot and see if it helps. Nothing to lose I guess. Should I mow before or after aeration?

Either, but if it pulls cores that don't fall apart instantly (which they prob'ly will on sandy soil), mow before. Afterward it's going to be a bit of a mess.

Post-aeration, do yourself a favor and topdress with a good organic material. Actually, any organic material would help eventually, down to and including peat moss.

Should I go for the normal 1/4" application or just enough to fill in the holes?

I don't have access to a nice garden store so I have to use the big box stores. It will probably be either peat moss or mushroom compost. Anything else good to try? Also is there anything else goog that can be spread through a rotary spreader. I won't have much time in the next few weeks to hand spread (tossout, rake or sweep in) anything. The fish are biting and calling my name.

The grass is soft and calling my name. :-)

1/4" will certainly help! That'll get some in the holes, plus a thin mulch layer for the grass. Don't go much thicker or you may smother the grass with it.

Peat moss is OK, as is mushroom compost. No problems there. Neither will spread well, but peat's so light it's easy to rake in. If you'd rather wait until after fish season, go ahead. Even atop the lawn it'll help.

How about Compost Peat Humus? The Lowes website says they carry that.

Also, I did a little calculating. At 1/4" to cover 4000 sq ft I will need about 3 cu. yards, 81 cubic feet. Right? I will probably have to buy bags as, like I said, there is no garden store/nursery to buy truckloads.

When I run the multiplier out (I use a standard .0007 times the number of square feet to equal cubic yards), I get 2.8. Three is not a significant difference and my multiplier isn't perfect, it's just an off the cuff number.

Compost peat humus would also be just fine. I'd say that, since you need a fair clip of the stuff, whatever's cheap and easy for you to handle is best.

Peat moss bales, at the very least, are compressed to about half their actual size. The 1.5 cu ft ones are actually 3 cu ft once it expands. Peat's also relatively cheap and, from recent data I found, reasonably renewable when managed intelligently.
