Cherimoya selection experiment in Vacaville, open ground.


Back in the spring of 2015 I started with 150 cherimoya seedlings in 1 gallon bags. Ninety one plants survived their first summer. About half were up-potted to 5 G pots to go into their first winter. The remaining plants were left in 1 gallon bags.

A couple dozens survivors were planted in ground (by the building wall) in the following spring (2016). More trees died in the following years. Now there are only one strong vigorous tree that bloomed and fruited in 2021. The tree experienced the range of temperatures between 23F - 114F. It grows by the Southern wall and does have some protection from the building.

The first fruit was produced in fall of 2021 without hand pollination. There is another small fruit developing on the tree. The ripe fruit was very pleasant in flavor and sweet, medium in size. I collected all seeds and started germinating them.

I plan to start propagating this tree in spring of 2022.


  1. Hi Maria..I just bought a farm in Sweeney Road which is at the border of Vacaville and Winters, off 505. I am interested in what you are doing. I have a couple of atemoya I want to grow in Winters. One has a small fruit now. It is a graft with a gefner and Africa Pride and another variety. I have 400 passionfruit vines planted already.

  3. Здравствуйте, Мария.Вот как вас можно найти в посыланиях из разных форумов.Держу дома зимой несколько сеянцев черимои.Вся масса молодых не пережила темной зимовки при низких положительных температурах.Может ли окрепшее деревцо выжить в этих условиях?Ваше предположение.У нас тут много желающих выростить черимою.Василий, Киев.

    1. Здравствуйте, Василий. Мне трудно сказать. Холодная веранда зимой им больше подойдет. Совсем тепло зимой им тоже не надо. В открытом грунте они у вас точно не выживут. От 5 до 10С со светом зимой им лучше всего.

  4. Way to go, Marta. Just reading about this now. What a cool experiment - a combination of zone pushing and selective breeding. I hope this variety and its progeny get distributed widely in marginal growing zones.
