How Much Asparagus Should I Plant?

Asparagus spear just starting to become overmature for best quality Q. I’m gardening in raised beds that are 4′ x 8′. I’m not sure how much asparagus to plant. My wife and are I the only ones who would eat it and I’m guessing we would harvest 1x per week during the period they are harvestable. How much of my garden would need to be dedicated for that production level? A. If asparagus is planted correctly it should start producing in February and you will stop picking about eight weeks later. When asparagus is in production and when it is warm outside you will picking as frequently as every other day to stay ahead of it. If you don’t, much of it will be unusable. There is no such thing as picking weekly with asparagus once it is in production.             It does freeze well, it makes great soup and they can be grilled nicely. I would say half-dozen crowns should be plenty for you and your wife. My asparagus class will be offered in March at Plant World and through Eventbrite.com.

Replanting In Same Hole for Fruit Trees Usually Not a Problem if Borers are the Reason

Q. I removed a diseased (clarified by saying the only problem was borers) peach fruit tree.  How soon can I plant another peach tree in the same hole? A. If this is from borers, then you can plant immediately. Not a problem with borers and replanting. The entire lifecycle of the borers in our fruit trees are in the aboveground portion of the trees, not the roots or soil.             There is a problem potentially with something called replant disease but it is minor in this case and should be not a problem for you. Remove as much of the root system as possible before planting.

Removing White Salt Deposits on Walls With Acid

Q. Our backyard block wall has some white stains on it. These appear where the sprinkler water hits the wall and I want to remove them.  I have read on-line to use things like diluted muriatic acid, but I don’t want to kill the plants my wife has throughout her garden.  How can I clean the stains, and can I treat the walls to protect from more stains forming Salt deposit on slumpstone wall when plants are being irrigated by bubblers. Salt in the water is carried up the wall where it evaporates, leaving behind the salts. The other side of the wall does not have sprinklers hitting it either. A. These are salts remaining from either those sprinklers or water from the soil wicking up the wall. Our soils contain quite a bit of salt as well as our water. Water coming from Lake Mead carries about 1 ton of salts for every 326,000 gallons. It sounds fairly dilute but it is not.              Our soils vary much more in salt and can be removed by leaching. The salt in the water of course is consistent. The combination of the two can mean some pretty high salt levels. Salt dissolves readily in water and when the water evaporates from the wall, it leaves the salt behind. These are probably the salt deposits you’re seeing on the wall. Even drip irrigation can cause problems like this since the water can wick through and into porous surfaces.             You don’t have to use muriatic acid but you can use and acid, even vinegar to help remove it. The major concern with plants is having the acid fall on foliage. This will damage the plant. Of course the best way to prevent it is to not use overhead irrigation.             In the case of drip irrigation, put the emitters on the opposite side of the plant from the wall, not next to the wall. Perhaps there is a treatment to the wall that could prevent this from happening. I don’t know of any.

Special Deal on Fruit Trees on My Twitter Causes Frustration – For Me!

Q. Your twitter feed mentioned a good deal on peach trees which we are going to now purchase. Which two peach trees to get for a 10 x 10 space? I’d like to keep the harvest staggered so we can enjoy the fruit longer. I also have a five-gallon Bonanza dwarf peach in a whiskey barrel that I started last October. https://twitter.com/ or go to my home page and follow my Twitter there. Stark Saturn peach with some bird damage. For some reason birds LOVE this particular fruit. Problem: SO DO WE! A. This was a special deal on ten fruit trees for $199 plus $35 shipping on Groworganic.com. On the peaches that they had available, I would recommend that you look at Red Haven (yellow acidic), Babcock (white subacid) or Stark’s Saturn (donut, white, subacid, but birds like it alot). For an earlier peach, mid July or so, and Indian Free (late august, beautiful flesh turning nearly blood red and subacid) or O’Henry (early august, yellow, favorite at roadside stands and farmers markets) for a later peach.             It is hard to recommend just one or two peaches since they can be so different from each other. There is not really a June peach in the group that I know well enough to recommend.

When to Transplant Fruit Trees?

Q. With this unusually mild LV winter, when is the best time to transplant dwarf grapefruit trees? A. By transplant I take it to mean you are moving a grapefruit from one location to another location. Planting or transplanting can be done now. You will have more success if the tree has not been in the ground more than three years. You will have even more success if the tree has been watered by drip irrigation in a fairly small basin or area next to the tree. You will have even more success if the tree was root pruned last fall around mid to late September. Roots of M111 on 12 yo Anna apple. We remove fruit trees from the orchard as we learn about them and then move on to those varieties we have not explored. Root systems can get large quickly and make it no longer feasible to relocate older fruit trees to new areas after about three years in the ground             Root pruning just means you went around the entire tree with a shovel and severed the roots in the approximate location where you are planning to dig and transport it. Given all that, prepare your hole for planting first before you move the tree. Dig deep enough to accommodate the root ball but not much deeper.             It is more important to dig it wide than it is to dig it deep. Get your soil amended and add some phosphorus to the soil. Move your tree as quickly as possible to its new location and try to orient it in a similar orientation, north to south, as it was in the old location.             Backfill around the tree. During planting, run a hose in the hole at the same time you backfill to remove air pockets. Drive a stake next to the tree and into the bottom of the hole into solid ground. This stake will immobilize the roots if tied to the tree tightly.             I usually use rebar pounded into the soil next to the tree after it has been planted. I wrap the tree and rebar together with green nursery tape to immobilize roots. This leaves the top to move in the wind.             The trees should be planted the same depth as it was when it was removed from the soil. No deeper and no shallower. If you have rabbits, protect it with one inch chicken wire after planting. Mulch the soil around the tree with wood mulch keeping the mulch away from the trunk a foot. After one season of growth, remove the stake.

Apples Planted As A Hedgerow May Need Special Rootstock

Q. I planted ten bareroot trees I picked up at the orchard yesterday. I followed the directions from your Blog and everything went really well. I cut them all off at approximately knee height but when I got to the apple, I wasn’t quite sure what to do.  Should I cut off any side branches? Leave desirable ones? Cut them partially back? Or just leave them alone? I am planting my trees in hedgerows 10′ apart with 4′ between trees. A. In hedgerows make sure the trees are on very dwarfing rootstocks. M111 rootstock is probably not aggressive enough for planting that close. You could do them maybe six feet apart but four is really close.  Birdseye view of young apple tree scaffold limb development             If any of the branches can be bent down and they touch the ground they should be removed to the trunk. The lowest branches are probably going to be somewhere around 18 inches to 2 feet off of the ground.             On apples look for a whorl of branches, a minimum of four and probably a maximum of six, to leave attached to the trunk. These will be your scaffold limbs which are limbs that support other limbs which bear the fruit.             Otherwise, if this is to be a hedgerow, you can wire trellis the limbs to support them so they don’t touch the ground and you could keep limbs as close to a foot off of the ground if you wanted to.             If you are not sure what to do even after reading this just remove the ones that you know are too close to the ground and leave the rest, come to the orchard so we can talk, and address the problem next year.

You Can Grow SOME Berries in the Mojave Desert

Womack blackberry grown at the orchard Q. Have you had any luck with berries? I have a friend that says she does blackberries successfully. A. Some blackberries will do just fine here and others do not. Two blackberries which I have found to work well here are Rosborough and Womack, both of which you probably have to purchase online. They come from the Texas A and M breeding program. One that did not do well from that breeding program is Brazos. Dorman Red raspberry grown at the orchard             Generally speaking, I would not recommend most of the blackberries with native American names such as Apache, Navaho, Arapaho, etc. which came, I believe, out of the Arkansas breeding programs. Historically they have not done well here according to locals who have tried them so I did not bother trying them. Strawberries at the orchard             Raspberries have not done well over time generally speaking. I did try a Florida variety which had a lower chilling requirement and it failed here. I have heard some reports from locals where they had some success with raspberries but they either did not remember the name or had them in for only one or two years. Others have generally reported failures with raspberries.             Strawberries will do well with everbearing types probably doing better than the main crop varieties. You will have some iron chlorosis problems, yellowing, that will need to be addressed. I have liked them when they were growing under about 30 to 40% shade here.             With all of these you MUST prepare the soil adequately prior to planting.

Lemon Can Get By On Few Hours of Sun During Winter But Not Other Times of Year

Q. I have a Meyers lemon that is currently potted.  Now that I have lived through a winter here I have paid better attention to my sun. There are two spots along the back wall that get maybe 3-4 hours of direct sunlight at the shortest time of year.  Do you think it would survive being planted against a warm cinder block wall with only that much sun?  Gloria Caruso’s immature Eureka lemon in Las Vegas A. Meyer lemon will freeze back in our harshest microclimates in the Valley. On the other hand some of the more tender citrus, such as the limes, can handle our winters just fine if they are placed in the right microclimate. The number of hours of sunlight in the winter is probably not as important as the number of hours for the rest of the year. Certainly four hours of sunlight is far too short for nearly all fruit producing and flowering plants if this light is during the spring, summer and fall months. But if this plant receives eight or more hours during these non winter months, when temperatures are at least warm, it might do just fine. To protect from freezing temperatures in the winter it is best that it’s placed near a very warm winter wall with very little exposure to wind. Some people wrap or drape them with materials and other use heat sources such as Christmas tree lights along with draping.
