Raspberry bushes create dark-red yellow, purple or berries depending on the variety. In Sunset Climate Zones 1 through 34 and 24 through 43 grow best in full sunlight to partial shade. Red raspberries developed in areas with plentiful rainfall are vulnerable to rust. Yellow rust is caused by the fungus Phragmidium rubi- . Small blemishes that are yellow appear on the leaf area of infected crops in the spring. Yellow rust can spread from plant to plant defoliation and bad fruiting when untreated.
Plant disease-free raspberries in full-sun. In places with well-draining soil and good air circulation. Space person raspberry crops 2 1/2 to 3 feet apart in rows. Plant row 6 to 10-feet away from each other.
Tie canes to stakes or a trellis utilizing string. Wrap the string round the cane 3 to 4 inches and tie it loosely. Space person canes at least 3″ away from each other when tying to permit air to circulate through the middle of the plant and dry any dampness caused by watering.
Water raspberry crops at ground-level. Avoid splashing water just as much as possible to avoid the fungus spreading to the plant in the soil. Water plants only through the day to give sufficient time to dry before night-fall to the crops.
Pull weeds from around the raspberries, keeping the floor free of vegetation that is excessive. Clean up fallen twigs, leaves and debris in the ground using a rake to eliminate components that protect the fungus spores. Other and the weeds eliminated components in a trash bin.
Raspberry crops in the spring as a preventative measure using a fungicide. Use the fungicide twice during dry periods during wet periods and every 7 to 10 times. Use fungicide to handle little outbreaks of rust through mid-July.
Cut out infected canes with pruning shears as quickly as rust is detected. Wear gloves when operating with raspberry canes to prevent damage to your own hands. Afflicted canes that are clip straight back to floor level. Pour 10 percent iso propyl alcohol remedy in a bucket or bowl. Dip the blades of the pruners to the the perfect solution is after each cut. Canes were afflicted by place throughout removing in a plastic bag. Rake up any dis-eased leaves on the floor and place them in-the-bag. Burn the discarded plant parts that were dis-eased to destroy the rust spores.
Dig up seriously dis-eased crops using a shovel. Burn the eliminated plant to remove the illness. Avoid brushing the plant throughout elimination against crops that are healthful.
After the canes have become dormant, prune ruined, dis-eased and dead canes in the drop or cold temperatures. Remove onethird of the plant’s development to start the plant’s middle for better air-circulation and sunlight publicity throughout the growing period.
