Growing Tips (Fall)

- Fall is a season that should not be overlooked for proper vine management. Even though the plants are shutting down, they still require water.
- You want to have a slow, steady shutdown into the vines, so they’re ready and prepared for winter’s cold weather. So it’s important to water them, but only moderately because you don’t want them to keep growing and risk damage from a winter frost.
- Fall is a good time to do a petiole analysis, which lets you know the nutrient composition of your vines. With this knowledge in hand, you will be able to give your vines their proper balance of nutrients before they go dormant for the winter.
- During this time of the year, you also can look for any visual viral symptoms as well as sending your samples in for testing, should you suspect a possible virus.
- Please feel free to call Wonderful Nurseries for additional Fall growing advice that is pertinent to your specific vines and conditions.

Growing Tips (Winter):

We know that after the dry winter of 2012, some growers had difficulty this year with new vines and even established vineyards getting off to slow starts due to lack of adequate deep moisture in their fields.

If this coming winter follows as another dry one, it could cause problems with late 2013 vines, especially potted vines. New roots are near the surface and soil must not be allowed to dry. Vines will not require the same amount of water they need while active but roots continue to develop during dormancy. Vines in dry soils are at much higher risk to frost damage as well. If you know a heavy frost is forecast, irrigation ahead of the frost will give vines some protection.

We recommend you monitor soil moisture regularly throughout the winter months to ensure your vineyards gets off to a healthy start next spring. If you have any questions or concerns please contact your sales rep or feel free to call our office and we will be happy to assist you.

When it comes to winter vineyard management there are a couple of things you should remember to do.  First of all, trim back last year's NEW planting to two buds per vine and secondly, remember to water the vineyard throughout the winter IF THERE IS a lack of rain (which a lot of us are currently experiencing).

Growing Tips (Spring):

Acclimation: (keep vines moist, not wet and in the box in a shaded area).  Acclimation time should be increased for plantings as season progresses and growers should wait until buds push before planting on all orders shipped after May 1st. Soaking roots in water for a minimum of 4 hours is also recommended after acclimation before planting.

January - February 15th, No Acclimation Necessary
February 16th - 28th, 3 Days
March 1st - 15th, 5 Days
March 16th - 31st, 7 Days
April 1st - 30th, 10 Days
May 1st - 31st, 14 Days
June 1st - Anytime After, 14 Days Plus Rehydrate Vines Before Planting

-After May 1st buds should be starting to push in the shipping container/box before planting. 
-Hydration of vines can be helpful and can be done between 4-24 hrs before planting.    
-Dormant vines are shipped directly to the customer from cold storage unless the customer requests acclimation.   
-Please plan your shipping and planting accordingly.  Rushing to plant vines can cause higher than normal losses.  
-Once vines are received keep them in a shaded area in the packaging in which they were shipped until ready to plant so they do not dry out.  
-If taking delivery of multiple boxes that are palletized it is recommended that the boxes be removed from the pallet in a single layer on the ground for even acclimation.   
-If the weather forecast is calling for hot, dry weather it is better to leave the vines in the box in a shaded area and hold off on planting until there is a break in the weather.  
-A fold top carton is recommended for all dormant plants planted after May 1st.   This should be completed as vines are planted or not more than a few hours of planting as damage can occur very quickly to exposed vines.

Growing Tips (Summer):

Summer may be an off-season for planting, but it is still important to conduct routine maintenance that sustains the viability of your harvest. And it’s smart to get your fertilizing finished early so that your vines can reach dormancy at the proper time.

The material is particularly susceptible to heat stress during this time, so make sure that the vines receive sufficient water. Be diligent though, because overwatering can be just as harmful as under watering. Many growers like to use water sensor probes that are inserted into the ground to measure the correct water balance. Keep in mind, too, that younger vines need to be watered more frequently, but in smaller quantities, because their root system is closer to the surface. As the plant grows and the roots mature, longer but less frequent watering periods are recommended.

Good weed control should also be addressed during the summer months. This is crucial because weeds compete for moisture and nutrients. As a matter of fact, summer is a good time to conduct petiole analyses, which enable you to determine the nutrient composition of your vines as your fruit is maturing.

During summer, maintain consistency with your spraying program for mildews and funguses. If you don’t keep these year-round threats under control, it could effect the quality of your vines, long-term.

Use the summer months as a time to maintain and nurture your plants, keeping them free from heat stress, weeds, pests and pathogens. If you follow the proper steps, you should be right on schedule for fall.
