The group, which owns B&Q and Screwfix in Britain and Castorama and Brico Depot in France and other markets, said on Monday both the do-it-yourself (DIY) and trade market were proving "resilient" and it was maintaining its full-year guidance.
Kingfisher said B&Q sold 730,000 units of vegetable plants, such as carrots and peas, 170,000 units of tomato plants, 160,000 units of strawberry plants and 370,000 units of herb plants. Sales of summerhouses were up 72% year on year.
Shares in Kingfisher were up 2.8% at 0740 GMT, paring 2022 losses to 25%.
It said group like-for-like sales fell 5.4% in the quarter to April 30 year on year but were up 16.2% on a three-year basis.
It said it was making strong market share gains and had good momentum into the second quarter with like-for-like sales down 2.5% for the two weeks to May 14 but up 21.8% on a three-year basis.
More people discovered or rediscovered DIY during the COVID-19 crisis as they spent more time at home, had fewer leisure options and travelled less.
Kingfisher said it was continuing to manage inflation pressures effectively and product availability was good, approaching pre-pandemic levels.
Despite economic uncertainty, it reiterated full-year 2022-23 guidance for adjusted pretax profit of about 770 million pounds ($967.5 million), down from 949 million pounds in 2021-22 when sales were boosted by the pandemic.
It said it would return a further 300 million pounds of surplus capital through another share buyback programme.
"We are focused on delivering on our strategic objectives and growth initiatives, including the growth of our scalable e-commerce marketplace, the expansion of Screwfix in the UK and France, (and) new store openings in Poland, further increasing our trade customer base," said Chief Executive Thierry Garnier.
