How many sweets do I need for trick-or-treaters?

Budget 4-6 sweets per trick-or-treater. In a busy neighbourhood, you might get 50-100+ visitors. In quieter areas, 10-30. Last year's numbers are your best guide. Always buy 20% extra - it is better to have leftover sweets than to run out and disappoint children.

How many pumpkins do I need?

One large pumpkin by the front door is the minimum. For a party, place pumpkins along the path and on tables. A good display uses 3-5 pumpkins of different sizes. Carving pumpkins cost £2-£5 each from supermarkets or £1-£3 from farms and markets.

What Halloween decorations are essential?

A carved pumpkin with a candle is the classic must-have. Fake spider webs, battery-operated candles, and a spooky door wreath make a big impact cheaply. For parties, add dim lighting, themed tableware, and cobweb tablecloths. Budget £20-£50 for a good home display.

What are the best Halloween sweets for trick-or-treaters?

Individually wrapped sweets are best (Haribo, mini chocolate bars, Swizzels). Avoid nuts (allergies), unwrapped sweets (hygiene concerns), and very small items (choking hazard for little ones). Fun-size chocolate bars are always popular. Buy multipacks for the best value.
