    I picked up the information about your grass seed at the Home and Garden Show. It looks like a good mix for me, but I'm not sure when I can plant it. Can you help?

    We're getting closer but we're not quite there yet. The soil temperature has to be at least 55 degrees to germinate seed. That usually occurs in mid-April. Seed can be planted anytime from then on until fall, but the success rate is much higher when the temperatures are cooler. The seed must be kept damp until germination, and that is much easier to do in spring and again in September - October. Thank you for your question - and also for stopping by our booth.

    My lawn last year had large areas that appeared to be drying out. I applied more water in those zones and tried the lawn tonic and fertilizer with no improvement. I take a lot of pride in my lawn and hate this happening. I know grass will go dormant in high heat but does that mean it has to look like hay? Thanks.

    Dry spots in the summer are very common in Colorado, and there are a couple of primary causes. The first and most common is soil compaction which can be improved by aerating the lawn in spring. Another way to reduce compaction is to use Richlawn Turf Food, or Richlawn Pro-Rich along with a couple of applications of Revive. These products will help to move the water down to the roots and prevent them from dying back during the stress of summer heat. The other main cause of dry spots is lack of water, but if you use Richlawn and Revive, that issue will be significantly reduced. I would avoid the popular lawn tonic recipe that is out there now. Some of the ingredients actually tend to dry out the cuticle of the grass blade, which over time can cause some problems. Thanks for writing to us.

    I have the Fall-Winter Turf Food (15-3-6) and wanted to know if I can substitute this for the Pro Rich Turf Food (14-2-5)for a spring application now in mid to end of March? Do you think this is OK or am I better off saving these bags for fall? Thank you, Chris, Good Plugs Aeration & Lawn Service, LLC

    If you have fertilizer left over from fall it is perfectly fine to use it in the spring. For your second application you can go back to the regular Pro-Rich Turf Food.

    My lawn has what I have always called fairy ring. I understand it is some kind of fungus. 1. how can I treat it? 2 will rich lawn turf food add too much nitrogen? (which I have been told is the problem)

    Fairy ring is a best controlled with a combination of wetting agents and aeration; deep aeration to allow water to percolate down to the roots. Also, fertilize a bit more often with organic fertilizer like Richlawn 5-3-2 (every three weeks, lighter than package recommendations) to mask the symptoms. If areas are really bad, dig the infected areas and resod or reseed. You will need to remove the whitish-gray mycelium or root structure to be sure you've got all the disease spores.

    I have a bluegrass sod lawn that is experiencing what I have been told is necrotic ring spot. How can I treat this? It has been told to me that too much niotrogen is one of the culprits. What do you suggest to help solve this issue. It has taken over about 20% of my back yard.

    Necrotic ring spot is a very challenging lawn disease to control as it is persistent in weak lawns. Follow good cultural practices of core-aeration, deep less frequent watering and organic fertilizers that are lower nitrogen and slow-release. Pesticides are generally not effective and very costly. Reseeding with disease resistant varieties of grass is also quite helpful and will thwart the disease. Richlawn EZ Green grass seed blend would be a good option, as it is resistant to necrotic ring spot.

    I had a sprinker system put in last July and reseeded the trenches but am having trouble getting the grass to grow. I reseeded again but you can still tell where the trneches are. Should I wait and see how things look this spring after the lawn greens up or do I need to resod those areas?

    Hopefully you seeded with a variety of grass seed (not a patch or grass mixture) that will match the current sod; give it time to fill in and mow accordingly. New grass in trenched areas where the soil was disturbed is generally more vigorous due to the good aeration and drainage.

    I just had the deep aeration done yesterday and I want to know if I need to apply the Pro Rich Turf Food today and when to do some seeding also. Please help!

    Aeration is a great thing to do for your lawn in the spring, and it is a good idea to fertilize and overseed afterwards. Pro-Rich can be used at the time of seeding, due to it's organic base, and we have a new grass seed blend that was formulated for the Colorado front range. It is called Richlawn EZ Green, and it is available at most garden centers.

    I applied Richlawn Turf food yesterday based on a rainy weather forecast. It did not rain and is not supposed to rain for a couple of days. My sprinklers are not on yet. Do I need to water by hand or can I wait another couple of days until it is supposed to rain?

    Richlawn fertilizers are organic-based and do not need to be watered in immediately after application, unlike the fast-release synthetic fertilizers. Of course, if you can water it in with a hose sprinkler, before the sprinklers are activated, this will help get the Richlawn to activate and start greening up the lawn.

    Why should I purchase Richlawn over what I have been using from Scotts?

    It's a matter of gardening philosophy and using products formulated for our region. Richlawn is locally formulated for our soils and growing conditions, unlike the national brands. Also, being organic based, Richlawn releases slowly over a longer period of time and helps to condition the soil over the long run. Plus, you're not likely to burn the lawn from an over-application or not watering in immediately which is common with synthetic lawn fertilizers.

    Every spring my rear yard is covered in yellow spots from my female dog. What do you recommend I do to fix the yellow spots and/or what can I do to prevent them, short of getting rid of the dog.

    The most effective way of preventing damage from female or male dogs is to train the pet to relieve themselves in a specific area rather than “Rover going all over!” Dogs are never too old to be trained. Otherwise, use a wetting agent like Revive after you thoroughly core-aerate the dog spots. This will dilute the urine and allow the spots to start regrowth and fill in. Also, to mask the spottiness appearance in your lawn , fertilize with Richlawn to help mask the darker green spots so everything blends in.

    What setting do you recommend for a fertilizer spreader in order to get proper coverage with the organic richlawn?

    Richlawn is organic so the spreader setting is generally set to deliver the pellitized granules to come out easily. I suggest that you open the spreader setting to deliver at 50 to 60 percent; for example if your spreader is calibrated from 1 to 18, set the spreader at 9 or 10.8; check to see if the fertilizer is coming out properly over the driveway covered with a tarp so you can collect the fertilizer and avoid staining the concrete. Water the fertilizer into the lawn after application.

    I have been told I have Necrotic Ring Spot. I did just fertilize with Revive and ProRich (green bag), with aeration prior to that. It is now the middle of April - and I understand I should fertilize every 6 weeks with a low nitrogen slow release product. Which of your products should I purchase. I also want to try and reseed - should I pick up the old damaged turf? Can I do my yard in sections for reseeding as I have a very large yard.

    Continue to fertilize every 4 weeks with the organic-based Richlawn products at the recommended rates. Also, if the lawn has not been core-aerated, have that cultural practice done in the spring before the weather gets too hot. If you desire to reseed, do this after aeration so the grass seed will lodge in the holes left from aeration. This will allow the seeds to germinate more successfully. If there are dead areas from NRS, dig these out and replace with soil amended with compost.You can do sections at intervals, but seeding is best done now while it is cool and moisture is available.

    I have euonymous (?) shrubs and they have been hit by a disease that starts as yellowing of the leaves and ugly woody growths on the stalks. the plant eventually dies and the woody stalks are covered by a powdery material. this disease only affects these plants - plants next to them are unaffected. I have asked around and nobody knows what i'm talking about. I hope you can help me.

    This problem with euonymus is likely a virus that is not treatable. It is best to remove the infected plants and replace with healthy ones. To verify you may pursue the assistance of a plant pathologist at CSU.

    Great products, keep up the good work! Had one question on the Garden soil mix. I usually mix in EKO compost into the native soil for my vegetable garden, is the garden mix made to till in or could i just fill up the boxes with the soil?. Or do you think EKO Compost is the way to go for vegetables? You have so many great products to choose from its hard to make up my mind. Thanks for your time.

    If you desire, you can plant vegetables and flowers directly into boxes or containers filled with EKO Outdoor Planting mix, but your native soil can be improved with either EKO compost or the outdoor planting mix. Consider the amount needed to determine if this works with your garden budget. Plant at the proper depths and water in thoroughly. Be sure that containers have proper drainage. To prepare native garden soil, continue to use EKO Compost added to the soil at the ratio of one third compost to two-thirds native soil. Use EKO every garden season and you will soon have a rich, loamy garden soil.

    It is most likely bunches of tall fescue; the safest control is to dig the clumps out with a sharp shovel and repair the areas by planting fresh sod cut to fit the areas. Keep watered daily and it will have rooted in. Fertilize with Richlawn Turf Food to help mask the discolored portions. If this coarse grass is all over the lawn, you may consider starting over or live with it.

    Summer is the best time to apply Iron Rich as it is non-burning and this is when cool season lawns need the additional boost with iron nutrient. After application, be sure to sweep concrete surfaces before watering. You can use either a drop spreader or rotary type; I prefer the rotary spreader for more uniform application.

    Our yard has never been grass, last fall we pulled all the weeds, rototilled and then added 13 yds of planters mix to the sandy soil. Then in the spring we pulled all new weeds (a lot less than we started with) and rototilled the soil again. We purchased 9 lbs of Richlawn E-Z Green Colorado Premium Turf Blend to cover our 1500sqft lawn. The seed was sown on April 12th, 2011. The grass is about 1" tall however, we have a large amount of clover, as we have had since we moved in, only now its in mixed in with our new grass. My question is when can we apply an agent to fight the clover and what type of agent do you recommend that is least likely to affect the Richlawn blend we used?

    It is best to wait until the new seeded lawn has been mowed at least three times before trying to control the clover. However, clover is an old-fashioned nurse-crop that adds nitrogen to the soil as a natural way to maintain a nice green ground cover. If you must use a commercial herbicide labeled for clover, read and follow label directions exactly as not to harm the new grasses.

    I applied Iron Rich to my lawn (fresh sod put in in Sept) two days ago. I added extra to a couple of yellow spots (one being really badly brown shaped like a half moon at the edge of my flower garden. Well it started raining for two straight nights that same night after I applied it and now the moon spot and about 5 other areas where it appears I added too much are totally brown, worse than they were before. Look burned. What should I do, wait a few days to see if the sun coming out improves the condition?

    Even though Iron Rich is organic-based, an over application or spills in the lawn during application can burn the crowns of the grass. Luckily, the roots and rhizomes of the grass are still alive and will fill back in eventually. Now is the time to core-aerate the areas where too much was applied and water well. The grass will begin to grow in and the spots should disappear within a month or so.

    Hello! I've been using your products for about 5 years and have been very satisfied with the results. I applied the Turf Food to my lawn in early April and now have a major problem with large areas of lawn that appear to be totally dead. Can this product burn the grass if it is not watered in enough? Even after all the rain we've received this past week, there has been no change to the problem areas (about 20-25% of the back yard). I would appreciate any information you could provide.

    When Richlawn is applied properly and at the recommended rate there is no problem with "burning", even if the organic-based fertilizer is not watered in immediately. It is when spills or an over application occurs that a slight burning may appear. However, the grass will grow back.
    Your problem with large areas dying is much more likely a fungus disease which often occurs with high moisture, or possibly an insect infestation. I recommend that you have the lawn checked by a reputable lawn service or your county agent.

    If the lawn was fertilized with a commercial grade synthetic, wait four weeks until you apply Richlawn. The issue of the lawn being a mix of clump grasses is not an easy one to solve. You may just have to live with it or if your budget allows, start over and plant a new lawn. You can also kill the clump grass areas one at a time using a Glyphosate product, and then re-seed the area with Richlawn EZ Seed mix.

    Sandy soils are notorious for leaching nutrients and can make lawn grasses more chlorotic (yellow) from iron and nitrogen deficiency. Core aeration with a topdressing of EKO Topdressing will help add some needed organics. Use the Iron Rich in summer to help keep the lawn green.

    Please tell me your suggestion on best watering practices. I am getting alot of different opinions. 3 x a week for 20 minutes a zone. Hot months, 3 x a week for 40 minutes a zone. Part of my lawn is very dry while the other is looking good. Don't want to overwater as I am trying to control the neucrotic ring spot. Also, having an extreme breakout of clusters of mushrooms, which appear in the sunny part of the yard. Any suggestions.

    This is difficult to answer as there is no single watering schedule for lawns as soils, drainage, temperature, and exposure will determine the turf‘s need for water. You must check frequently to determine which frequency works best and the depth of water percolation into the soil for your lawn.

    Common sense watering practices of watering in the cool of day,(set to come on between 3 to 6 a.m.) and watering long enough to get water to soak into the soil. The length of watering time will depend on the type of sprinkler head and amount of water delivered.

    Mushrooms are a result of high organic matter in the lawn which serves as the ideal environment for them to germinate and thrive. Aerate these areas to increase air circulation and reduce thatch buildup.

Also, can you make a recommendation to fill in the low spots on my lawn? The turf is in great shape so I don't want to start over, but need to fill those holes.

    EKO Top Dressing is finely screened, and can easily be applied using a broadcast spreader. As to filling in low spots, there are two methods and either one works well. The first is to add about a half inch of top soil every few weeks and gradually raise the level of the soil. The other method is to remove the sod in the low areas, level them and then put the sod back in to place. In either case, it is best to wait until spring when the grass is actively growing. The repair will take much less time.

    I have an area on the south side of the house that is currently "rocked" - removed yucca plants this summer, but need to completely sterilize the soil to kill all the weeds, sumac, etc. before doing anything else. What product do you recommend? Do I need to move all the rock (gulp!) What time of year should I do it? More than one application needed, etc? Thank you!

    If your intention is to plant this area with flowers or other landscape plants, you should remove the rock. Soil sterilants are not recommended, as this would harm new plantings and roots from trees and shrubs nearby. Continue to dig out weeds and spot-treat if needed with a short-lived weed killer. If you get started soon, you can plant this autumn with perennials, ground covers and other available landscape plants. Good luck.

    is necrotis ring spot a disease that comes from the sod farms when you put the new soil for your new lawn down? or does it have to be brought in or spread in the soil after that?

    Necrotic ring spot is rarely brought in from sod farms, most farms grow healthy turf or they would not sell it. This disease is already in the soil from an area where the lawn was already infected or there were stress conditions that made the disease opportunistic. Maintenance of the lawn is key to prevent this disease which includes proper soil preparation prior to sodding, good watering practices and regular feeding with a slow-release nitrogen such as the Richlawn products.

    We live in the northern Colorado area. I used your Pro-Rich Winterizer around the end of October. Only problem is my spreader stuck open and I didn't catch it in time. The area is a small front lawn but I calculate that it doubled the recommended application amount. It snowed right after the application so I couldn't "flush" the front lawn. The lawn after the snow is melting is turning a funny gright yellow color. Is there anything I can do this late in the game?

    There is really nothing to do other than to water monthly during dry periods over the winter. Due to its organic based properties, the excess application of Pro-Rich Winterizer is not a problem. Typically, turf grasses begin going in to dormancy in November which would explain the off-color you are seeing. Your lawn will be fine, and should green-up earlier in the spring because you applied winterizer in late October.

    Help! I am in Erie, Colorado. This is Year 2 of using Richlawn products (fertilizer and grass seed) and following Plant Doctor tips...and my lawn is amazing, a complete turnaround from years past! However, this summer it also seems to have attracted all new sorts of weeds. Too many to control with simple spot spraying (I think). I have not used any major weed control products to date. Do you have any tips, perhaps a calendar similar to your fertilizer calendar that includes tips for some kind of general weed control? Product recommendations would be great, too. Thanks!

    If you are a true organic gardener and do not wish to use herbicides, mechanical and cultural control methods are recommended. This means keeping the lawn thick with the Richlawn fertilizers as recommended on the label, five to six feedings a year. Core-aeration at least twice; spring and autumn. A thick, dense lawn will choke out most annual weeds. Perennial weeds are controlled with digging and pulling when the soil is moist; pre-emergent controls such as corn gluten in spring to prevent weed seeds from germinating in mid to late spring. Otherwise, you will need to return to chemical herbicides and spot treat according to the label directions. Select from the more environmentally-friendly weed control products and follow label directions carefully.

    We went on vacation and our housesitter failed to water our Zoysia grass. It is now brown like hay. Will it grow back? We live in Texas and the temps are over 100 right now.

    Zoysia is a warm season grass and is acclimated to drought conditions. Typically, warm season grasses go dormant with extreme lack of water, and then green-up when irrigated. The best thing to do is give it a good soaking and hopefully it will respond. Best of luck in the hot summer days!!

    We live south of Castle Rock in the foothills. Last spring we tilled 20 40gal bags of scrub oak leaves in our garden and this year the garden did not produce like last year. Are the oak leaves good for the soil or do we have to add something?

    The lack of production from the garden this year, and the addition of scrub oak leaves are unrelated. This year has been challenging because our erratic weather. Cool, then wet, and then hot and dry. Oak leaves are great to add to the soil, but if you do add lthem in the future, be sure they are dry so they will break down in the soil faster. EKO Compost would also be something great to incorporate in to the soil.

    We live in Colorado Springs. Our flower beds and rock gardens are being taken over by clover. We pull out the clover often but it keeps returning. There are now some patches of clover in our lawn. We sure need a solution to this problem and will appreciate your advice.

    Clover is a perennial plant, which means it comes back year after year. Unless you can get every bit of the root (which is nearly impossible to do) the plant will shortly re-generate. If you can treat the clover without contacting desirable plants, then Roundup or another product containing glyphosate would solve the problem. If that is not possible, pieces of black plastic placed over the plants will deprive them of water and will kill them. Other than that, your best bet is to continue to pull them manually. Eventually, the root will starve and the plants will die. That method does take a good bit of time though.
