i am in senior highshool agricultre and we are currently growing zucchinis for a assignment along with other crops , but all the zucchinis we have grown grow to a huge size and taste watery and bland , any ideas why?

Hannah, it sounds like you didn't pick your zucchini early enough. Once the fruit are set I find that you need to pick them as soon as they reach an edible size. That's anything over about 5cm, depending how we're planning to use them.

Hannah, I have grown huge zucchinis too and what I do is just cut the top off and hollow them out then you go down to your local chinese and get your favourite takeaway or even just some fried rice and stuff them. pop it in the oven wrapped in foil until the zucchini is cooked and you will never look back!!.

large zucchini i cut in half length wise scoop out some flesh and fill it with a bolognese sauce and cooked rise mixed into the sauce. fill the zucchini cover with foil and bake in the oven can also have some cheese melt over the top to finish if desired lovely dish

Great Stuffed Zuchinni Cut lengthwise, hollow out, par boil in hot water for 5 minutes for better taste. Meanwhile take insides and chop into bitesize pieces, saute with chopped onion, garlic, when almost done add in some chopped tomatoes. Can do many variations with Rice and even can add tomato sauce... whatever you like can be creative of just follow recipe. Mix with 1 lb sausage, hamburger or Turkey Burger precooked until done, drain off grease. Put in baking dish and Top with Parmesan Cheese and bake at 350 until cheese browns and Serve YUMMY!

I planted my Zucchini in July and they started fruiting about 3 weeks ago but they get to about 10cm and then the flower drops off and they dont get any bigger. they start rotting. What should i be doing. I only have the one plant, does it have something to do with germination??

marrows are a type of zuccini and dido but marrows taste better when larger that zuccini.Zuccini taste like cardboard after they have reached about 15cm

Lisa, zucchini/courgettes behave like that when they are not fertilised. You could try using a soft paintbrush to do it by hand.
