Мы купили дом в деревне, а вместе с ним нам достался очень запущенный сад. Пытаемся привести его в порядок, провели омолаживающую обрезку, счистили лишайники со стволов. Участок влажный, приходится бороться еще и с паршой. Посоветуйте, какое средство для этого можно использовать.

Действительно, в старых садах часто широко распространена парша на

Будет минус огороду

Возвратные заморозки подстерегают наши растения почти до до середины

Шесть лет назад купила сорт вишни Любская. Мне его рекомендовали как очень зимостойкий и урожайный, но у меня дерево за эти годы плодоносило только 2 раза. В чем причина? Расскажите об этой вишне подробнее, я слышала, что это старинный сорт.

В условиях Московской области вишня — культура рискованного садоводства.

Длинноногий салат

Салат уйсун распространен на Дальнем Востоке, но хорошо растет

Перец живет долго

Как ни странно, самая перспективная культура для средней полосы

Купил семена черемши и хотел посеять весной, но знакомый говорит, что черемшу сеют только под зиму. Так ли это?

Семена черемши прорастают только при подзимнем посеве или после

Ветки смородины и крыжовника обросли лишайником. Это опасно для растений? Посоветуйте, что делать.

Мхи и лишайники часто появляются на коре старых плодовых

Из чего лучше всего приготовить субстрат для выращивания вешенки?

Вешенка довольно пластичный гриб, у него нет специфических предпочтений.

Сосед бывает разный: хороший и плохой

Для экономии места часто совмещают посевы, чередуя ряды двух-трех

У меня не получается рассада летников на окне. Правда ли, что семена некоторых летников нуждаются в стратификации? Может, причина моих неудач в этом и стоило сначала подержать семена в холодильнике?

Стратификация — это обработка пониженными температурами уже набухших семян
