Use soil temperatures as a gauge when to start! Cool Season 45 F Warm Season 55F Very Warm Season 60F 2-3"depth late morning
Critical soil temperatures: Below ‘threshold temperatures' 45 F for cool season or 55 F for warm season Seeds: Seeds will not germinate or germinate very slowly. Cool season seeds will ‘sit there' until temperatures warm, warm season seeds may rot! Plants: Plants will not establish roots, start to grow, or (in some cases) not absorb water or nutrients. Cool season plants will ‘sit there' while warm season crops may deteriorate.
Soil temperature is consistent (stable for 3-4 days) Take soil temperature 2-3 inches deep about 10-11 AM Sandy soil warms up quicker than clay but sandy soil loses warmth more quickly in cool conditions Wet soil warms up slower than dry soil but holds heat better Microclimate (location around the home makes a difference)-slope, protected by fences, location around home or exposure
Soil Improvement Add organic matter. Apply in the fall season and till into soil.
Don’t work soil when wet. Allow to settle before planting. Good soil is made over time
Efficient application of water to plants. 75-80% of roots in upper ½ of root zone Cool season Warm season 18-24 in 24-36 in
Apply water to depth of active root absorption (12-15”) slowly and gradually so none runs off
Proper pest identification is critical to success in being able to select a proper control. Pest control Timely Effective for that pest Applied to where pest is Repeated if necessary
Spider Mites: Develop on undersides of leaves. Early detection is important. Standard insecticides not very effective (especially Sevin) Kelthane, sprayable oils (Sunspray), insecticidal soap (Safers) or Cygon. Watch for early ‘stippling’ on the upper leaf surface.
Cabbage worms from eggs laid on underside of leaves. Use a wetting agent to make water spread on foliage.
Wilting is not from lack of water Squash bug feeding on plants.
Watch egg clusters- they get darker just before hatch. Apply control measures when squash bugs are small and soft bodied
Don’t over-react! Apply the proper material at the proper time according to label directions in a thin coat to completely cover plant Probably best to use a fine mist spray with a compression sprayer. Not a duster or hose-end sprayer.
Rotation and Sanitation Use nutrients from soil more effectively Prevent some insect and disease problems Keep pests from spreading
