ToxicityTo humans
The plant commonly known as plum is not toxic to humans when the fruit flesh is eaten. However, the pits, leaves, and stems contain cyanogenic glycosides, which can release cyanide when ingested. If someone consumes crushed or chewed pits, they may experience symptoms of cyanide poisoning. These can include headache, dizziness, confusion, nausea, vomiting, difficulty breathing, and even loss of consciousness. In severe cases, ingestion of large quantities of cyanogenic compounds might lead to respiratory failure and death.
To pets
Plum trees, including the 'Cambridge Gage', can be toxic to pets if they ingest the leaves, stems, or pits. These parts of the tree contain cyanogenic glycosides, which can result in cyanide poisoning. Symptoms of poisoning in pets may include dilated pupils, difficulty breathing, panting, and shock. In severe cases, consuming large amounts of these cyanogenic compounds can cause coma or death. The fleshy part of the plum fruit is not toxic to pets, but care should be taken to ensure they do not have access to the dangerous parts of the plant.

WaterThe Cambridge Gage plum tree needs to be watered deeply, especially during the first few seasons after planting to establish a solid root system. Water the tree once a week with about 5 gallons of water, making sure to adjust for rainfall and soil type. During the growing season, if there's a prolonged dry spell, increase watering to twice a week. Reduce water quantity to around 3 gallons as the tree matures and relies more on its established roots. Always check that the soil is moist but not waterlogged to prevent root rot.
LightCambridge Gage plum trees thrive in full sunlight, which means they need at least six to eight hours of direct sunlight daily. The ideal spot is an open area away from taller structures or trees that could cast shade on the plum tree. Avoid locations where buildings, fences, or shrubbery will restrict the amount of sunlight, as this can reduce fruit production and affect plant health.
TemperatureThe Cambridge Gage plum tree grows best in temperatures between 65°F and 75°F but can handle winter chill down to around 15°F. It is crucial to protect the tree from extreme cold snaps that drop below this range, as it can damage or kill the tree. These plum trees can withstand high temperatures as well, but prolonged exposure to heat above 90°F may stress the plant.
PruningPrune the Cambridge Gage plum tree to encourage healthy growth, increase air circulation, and enhance fruit production. Pruning should occur in late winter or early spring before new growth starts. Remove any dead, damaged, or diseased limbs, thin out crowded branches, and shape the tree to maintain an open center. Pruning every year helps keep the tree productive and manageable.
CleaningAs needed
SoilThe Cambridge Gage, a European plum variety, thrives best in well-draining, loamy soil enriched with organic matter. A slightly acidic to neutral pH range of 6.0-7.0 is ideal for this fruit tree. The best soil mix would be a combination of garden soil, compost, and aged manure or a balanced organic fertilizer to provide nutrients.
RepottingThe Cambridge Gage plum tree, being a sizable fruit tree, is not typically repotted. Instead, after initial planting in the ground, it should remain in the same location as it has a large root system that requires ample space to grow.
Humidity & MistingThe Cambridge Gage plum prefers outdoor conditions and does not require specific humidity levels. It is adaptable to the natural humidity present in the environment where it is cultivated.
Suitable locationsIndoor
Not suitable for indoor cultivation.

Life cycleThe Cambridge Gage, a variety of European plum, begins its life cycle when seed germination occurs in favorable conditions of warmth and moisture. The seedling emerges and grows into a juvenile plant, during which time root establishment and shoot development take place. As it matures into an adult plant, it goes through a vegetative stage where it develops strong structural branches, foliage, and a robust root system. Following this, the plant enters the reproductive phase, characterized by the blossoming of white flowers in early spring, which are then pollinated by insects, leading to fruit set. The fruit, which is greenish-yellow and sweet when ripe, typically matures during late summer. Finally, as part of its perennial growth cycle, the Cambridge Gage will enter a period of dormancy during the colder months, shedding its leaves and resting until conditions are favorable again for the next growing season.
PropogationPropogation time
Summer-autumn
Propogation: The European plum, specifically the 'Cambridge Gage', is typically propagated through a process known as grafting, which is most commonly done during the dormant season, either late winter or early spring. Grafting involves taking a piece of a mature, disease-free plant, known as the scion, from the desired cultivar and joining it to a compatible rootstock. The scion, which is a shoot with dormant buds, is usually around 4 to 6 inches (10 to 15 cm) long. It is meticulously spliced onto a rootstock that has been specially selected for its hardiness, size, and compatibility with the soil and climate where the plant will be grown. The graft site is then sealed with grafting tape or wax to prevent dehydration and infection. After the graft has taken and the new plant begins to grow, it maintains the fruit characteristics of the 'Cambridge Gage' while benefitting from the rootstock's resilience and adaptability.
