I'm going to go ahead and resurrect this old post so hopefully someone can learn and hear from a different perspective from a professional. I would first like to mention, TexasWeed, I know who you are, I've read many of your post, and you have some knowledge. With all due respect, I respectively disagree with you in many aspects though. One of the paint points I disagree with you on, is you suggesting a SLOW RELEASE FERTILIZER in the original posters situation. While slow release fertilizers can be great in many areas, and especially in particular times of the year. This was not a great suggestion for the poster in my honest and fair opinion. Why? The poster is growing a lawn on sand. We know what that means. Lower CEC levels, and little nutrient holding power. Nutrients will never last as long in Sand. The same PPSCU, XCU, and Sulfur coated fertilizers that may claim 2-3 months, is not near the case for turf growing on Sand. Even for lawns growing on Clay such as myself here in Central Texas, many people fail to understand how "Slow Release" products work. Knowing the growth characteristics will put you far ahead of the game. Many PPSCU and various other slow release products contain coatings which are dependent on various factors. If you study these factors, most of these coatings are designed to be broken down with the main factor being "TEMPERATURE." Slow to release nutrients when cool, and they literally dump nutrients when soil temperatures are very warm. In Texas, this is the majority of the time, so what you get left with, is an over-priced bag of "Slow Release" that's dumping much quicker then "SLOW" due to high temperatures being exhibited. My approach, especially on dealing with "SAND" such as the poster is SPOON FEEDING quick release fertilizers. Bermuda especially, needs to be supplied adequate nitrogen for outstanding turf quality, density, and color. The goal is to feed the turf what it needs as it uses it. By doing so, the turf will continue to be fed, and the sandy soils that don't hold nutrients will continue to be ideal for the turf. The original poster had great improvements from doing 1/2 applications from Ammonia Sulfate every few weeks and this supports exactly what I'm saying. However, to the original poster, you are forgetting many important nutrients. A soil test will be MANDATORY for the perfect lawn. Without a soil test, I can't recommend phosphorus, I see enough of it around my parts of Texas. The problem is much of the phosphorus isn't available. Same with Potassium, except I consider this CRUCIAL. Your lawn needs potassium to aid in extreme temperatures and disease pressure such as what we have here in Texas. Potassium is a luxury consumption nutrient, meaning you put it down, the turf is going to use it, if in available form. Much of our potassium in our soils is NOT AVAILABLE when comparing from my recent soil test, to actual TISSUE TEST. Also, using 21-0-0 provides lots of Sulfur that will aid in bringing Texas's natural high pH down and will also aid in uptake up other nutrients, including our long lost Iron. If you've ever applied Iron in Texas, you'll notice, there might or might not be a response, if you get a response, it doesn't last. This is pH related and calls for using only CHLEATED IRON products which is much more usable and available to the turf in our area. If you want a usable mix, trust my word on this, try it, and come back to me and tell me you have the best lawn in the neighborhood after half a growing season. (You might have to source these products), but they are all available in Texas. Depending on your work schedule and free time you can adjust your rates and applications, but you need to apply in adequate water to avoid burn potential. Most likely, you will have to go with the lower spray rates and more often unless you have a high volume sprayer like we use that holds hundreds of gallons. Bermuda: Weekly Fertilizer Mix: .25N per 1,000 Sq. Feet (From Ammonia Sulfate 21-0-0) .25 (SOP) per 1,000 Sq. Feet (Potassium Sulfate) .50 ounces per 1,000 Sq. Feet (Micro nutrients with chleated Iron and mg and mn. The micro nutrient product is really important and will aid in giving your turf the color you are looking for. I (HIGHLY) suggest either using (FeATURE 6-0-0) by loveland products or Main Event Chleated Micro nutrients If you don't have the time to spoon feed your lawn weekly, you can adjust the rates, either double for bi-weekly, or multiply x 4 for monthly. Don't go longer then month long applications. The only catch is, 21-0-0 has burn potential. You will need at (MINIMUM) of 1 gallon of water per 8 ounces of 21-0-0 in your mix to avoid burn potential. Do not adjust the rates above, this mix is tried and true on Texas Turf and will leave you with the greenest lawn in the neighborhood. If you don't have a large enough sprayer with capability of putting out enough water volume, you're better sticking with granular fertilizers. We use 200+ gallon tanks, with walking booms for an even application. Nozzles on the sprayer are also important. We use TeeJet Air Induction and FloodJet tips to reduce drift, depending on the water needed for the application.

The first 6 inches were soft limestone rubble chunks and some soil., but after that it is a hard limestone. I dug a square 24''x 24"x 8" hole. I piled up the rock chunks elsewhere where I will use it and some boulders to plant a beavertail opuntia. I filled the hole with a sandy/composty mix and added in some of the native soil. This is very friable. I can break up the soil around it too. and add in more garden soil. I should be building a bed but I am a cheapskate by neccesity right now. Other plants (fragrant mimosa,Live oak) have ran their roots through the top rubble layer. I could mound it up above the hole more also.

Beautiful pictures, Sarah! I am just now seeing buds on reptans. I have 2 azureas- one from seed & one from a MAG swapper. The odd thing is that one has light green foliage & one has dark green, I'm curious to compare the blooms when the 2nd one starts. Do you know if there's a difference between S. azurea & S. azurea grandiflora? I can't figure that out on the net. Maybe someone knows... Rose

Glad you got a response on the Fruit & Orchids forum. Our native blackberries are the only fruit the squirrels don't totally decimate.... and the birds that do like them seem to know how to share. Starting to open a new area for some improved thornless cultivars - 'Natchez' and probably 'Ouachita' - but not enough experience yet to comment. Would be nice to know if the new primocanes can actually perform in north Texas - older varieties were usually not considered well suited. Though context is significantly further east than you, the Dallas Fruit and Vegetable blog has some good photos and posts about growing some of these in north Texas.
