Opuntia grandis

continental : Let’s try to keep the ground fairly damp, watering every 2-3 weeks with 1-2 glasses of water; when the weather is very harsh and the temperatures are below zero, watering can be interrupted.

alpine : Every 3-4 weeks water the soil, trying to wet it deeply; keep the ground constantly moist, although we must avoid water stagnations. Usually 0-1 glasses of water are used.

mediterranean : We suggest watering regularly with 2-3 glasses of water, trying to keep the growing substratum pretty cool and moist; if the climate is very cold we can reduce watering. 1-2 weeks should go by between irrigations.

continental : For the the Opuntia grandis let's prefer very sunny locations, directly exposed to sunrays.
The Opuntia grandis isn’t rustic; during the cold months it is grown in the apartment.

alpine : For a balanced development, it is best for the the Opuntia grandis to receive as many hours possible of direct sunlight.
During the cold months these plants should be grown in an apartment because they can’t stand the cold; it’s best to keep the minimum temperatures above 15°C.

mediterranean : Plant which needs to be exposed to direct solar rays.
In the winter it’s best to move these plants in the apartment, as they need minimum temperatures above 12-15°C.

Fertilization Opuntia grandis : During the cold months of the year we recommend suspending the fertilization of the succulent plants, to avoid them from producing too many “new” tissues, which resist the cold weather very little and are easily attacked by fungal diseases, which develop more easily during the plants’ resting period.

Treatments Opuntia grandis : Towards the end of the winter, when the days tend to become longer and warmer, we suggest applying a treatment with mineral oil, against cochineals.
