In segment four Joey and Holly answer gardeners questions

Q Last year i had pears that had brown scab like areas on them what might that be and how or what do i do to fix it
A: Apple Scab and Pear Scab
Apple scab Venturia inaequalis, and the closely-related pear scab Venturia pyrina, are major fungal diseases affecting tree fruit crops.
Scab is spread by airborne spores causing dark green, velvety spots on leaves and dark, scabby blotches and cracks on the fruit. The lesions affect the appearance of the fruit and seriously reduce the crop’s commercial value. In addition, the cracks leave the fruit prone to rotting which affects the storage capability. On young shoots the cracking can also provide entry points for canker.
Control is via fungicides such as Captan-based products which may need to be applied as often as 15 times each season.

How to Treat Pear Scab Naturally Controlling pear scab without chemicals takes some vigilance. Since the inoculum lives in the diseased plant material, cleaning up dropped leaves in fall can help prevent the spread. Removing infected plant materials can also have some benefit. The fruit is often widely infected in storage. Be very careful during harvest to sequester any fruit that exhibits even the tiniest lesion. If even one gets into a storage crate, the rest of the harvest could get infected. Sanitation and good hygienic practices are the only offerings for pear scab control without spraying. Controlling Pear Scab with Sprays Fungicide sprays need to be applied 2 to 5 times during the season, depending upon where the tree is growing. The most important spray is done just as the flowers become pink. This is usually followed every 10 to 14 days by successive spraying to eradicate all the spores. Lime sulfur sprays applied at the delayed dormant season (usually around February to the middle of March) can help prevent spores from activating. A combination of chemical and natural methods is the best method of controlling pear scab in regions with warm, wet weather during flowering and fruiting.
Just peel and eat unless the infection gets so bad that the fruit cracks or becomes misshapen and secondary rot organisms destroy it.
Q. Why are my zucchini flowers not opening ?
A: i t can be a sign of stress. Sometimes it happens when you have a squash vine borer, the plants can be too close together. ... They are huge plants and need space. If they are closed still, they are not yet mature
Q what do you do with the soil afterwards you harvest your crops in your grow bag
A: What we do is fill the bag half full with the soil (continued)
